What Is Humalog?
Humalog (insulin lispro injection) is a prescription rapid-acting injectable insulin analog (eg., it’s a manufactured insulin). This medication is used to treat diabetes. It works by lowering blood glucose (sugar) in the body.
Generic Name: Insulin Lispro
Brand Name(s): Humalog
Drug Availability: Prescription
Therapeutic Classification: Antidiabetic
Available Generically: Yes
Controlled Substance: N/A
Administration Route(s): Subcutaneous, intravenous
Active Ingredient: Insulin
Dosage Form(s): Solution
What Is Humalog Used For?
Humalog is a treatment option for type 1 and also type 2 diabetes (high blood sugar). In the United States, the Centers for Disease Control and Prevention (CDC) estimates that diabetes affects more than 37 million people—with prediabetes (when blood sugar is high but not high enough to be diagnosed as diabetes) affecting an additional 96 million people.
The National Diabetes Prevention Program (DPP) helps prevent or delay diabetes in people with prediabetes. If you have prediabetes and would like to know more about chapters of the DPP in your area, ask your healthcare provider for more information or contact a local program.
If you have diabetes, you might experience the following symptoms:
- Extreme hunger and thirst
- Frequent urination (peeing)
- Weight loss
Over time, uncontrolled high blood sugar levels can lead to diabetes-related complications, including neuropathy (nerve pain or numbness), diabetic foot sores, amputations, eye problems, and kidney impairment.
How to Take Humalog
In general, when using Humalog, take the following precautions:
- Carefully check the labeling on the package or container to make sure that you’re using the correct insulin product.
- Humalog should be clear and colorless. If you notice any color, cloudiness, or particles, don’t use it.
- Wash your hands with soap and water.
- If you’re using Humalog through a pen or an infusion pump, don’t dilute (water down) the insulin.
- Don’t dilute Humalog from vials on your own.
- When using an infusion pump, don’t mix Humalog U-100 with other insulins.
- If you’re injecting Humalog U-100 under your skin without an infusion pump, however, Humalog U-100 can be mixed with Neutral Protamine Hagedorn (NPH) insulins—like Humalin N or Novolin N. Other than NPH insulins, however, don’t mix Humalog U-100 with any other insulins.
- If you’re going to mix Humalog U-100 with an NPH insulin, draw Humalog U-100 into the syringe first before drawing up the NPH insulin product. For more detailed directions about missing insulins, talk with your pharmacist or healthcare provider.
- If you’re injecting Humalog under the skin without an infusion pump, use Humalog within 15 minutes before or immediately after your meal.
- Don’t use Humalog U-200 in an infusion pump.
- Don’t mix Humalog U-200 with other insulins.
- Don’t self-inject any type of Humalog directly into your vein.
- When switching between the Humalog U-100 and U-200 pens, there is no need to convert your dose. The pen has a dose window that shows the dose (in units) that you will inject.
- Don’t transfer Humalog U-200 from a prefilled pen into a syringe. Just use the Humalog U-200 pen to directly inject the insulin under your skin.
- Don’t repeatedly use the exact same injection or insertion (infusion) site within the same body region. Repeatedly injecting or infusing insulin in the exact same spot will raise your risk of thick, pitted, and lumpy skin.
- Don’t inject insulin into tender, bruised, scarred, pitted or damaged skin areas. Also, avoid skin that is scaly, hard, lumpy or thick.
Your healthcare provider can recommend which route you’ll use for your Humalog, which includes:
- Subcutaneous infusion through an insulin pump: If you’re going to use Humalog U-100 in an infusion pump, check the directions, which vary for each pump. Carefully read the labeling and packaging instructions. Talk with your pharmacist or healthcare provider for detailed information. In general, remember to change the Humalog in your pump reservoir every week, or after exposure to temperatures over 98.6 degrees Fahrenheit. Change your infusion sets and infusion set insertions at least every three days. Also, rotate your insertion (infusion) site within your chosen body region every three days. If you’re using a Humalog 3 milliliter (mL) cartridge for your D-Tron pump, you will need to throw away your cartridge every seven days.
- Intravenous (into your vein) infusion: If you’re receiving Humalog U-100 as an intravenous infusion, your healthcare provider will help give this infusion to you. Don’t self-inject Humalog directly into your vein.
- Subcutaneous (under your skin) injection: More on this next.
If you’re going to inject Humalog under your skin (subcutaneous), the specific directions will vary per person. Use Humalog according to your healthcare provider’s recommendations. The following, however, are some typical steps to inject Humalog under your skin.
- Use an alcohol swab to clean your injection site, then allow your site to dry.
- Use an alcohol swab to clean the rubber stopper of your Humalog vial.
- Carefully remove the cap protecting the needle of your syringe.
- Fill your syringe with air by pulling the plunger of your syringe back until the black tip reaches the marking of your Humalog dose in units.
- Push the needle through the rubber stopper of your vial, and push the plunger all the way down to force air into your vial.
- Turn your vial with the inserted syringe upside down.
- Then, slowly pull the plunger back until the black tip reaches the marking of your Humalog dose in units.
- If you notice any air bubbles, gently tap the syringe a few times to move the air bubbles to the top of your syringe—which is near the needle.
- If necessary, adjust the plunger in or out until the black tip is at the appropriate marking (unit) for your Humalog dose.
- Without moving the plunger, pull your syringe to remove the needle from the rubber stopper of your insulin vial.
- With one hand, gently pinch a fold of skin at your injection site which can be in one of the following body regions: butt cheeks, stomach, thigh or upper arms. The need to pinch a fold of skin will vary for each person. Talk with your healthcare provider to discuss the necessity of pinching your skin.
- Using your other hand, hold your syringe with the needle at a 45-degree to a 90-degree angle to your injection site.
- Continue to pinch your fold of skin while inserting the needle into your injection site and pushing the plunger of your syringe until there is no more insulin left in your syringe.
- Keep the needle in your skin for a minimum of five seconds.
- Gently stop pinching the fold of your skin and remove the needle.
- If you notice blood after you take out the needle from your skin, use a piece of gauze to gently press down on your injection site. Don’t rub the area.
- Throw away your syringe with the attached needle in one of the following containers: red biohazard (sharps) container, hard plastic container (e.g., detergent bottle), or a metal container (e.g., empty coffee can). For additional information on how to appropriately and legally throw away your syringes and needles, talk with your pharmacist.
- Use an alcohol swab to clean your injection site, then allow the site to dry.
- Remove the cap from your Humalog KwikPen.
- Use an alcohol swab to clean the rubber stopper of your KwikPen.
- Peel off the circular paperlike seal from the needle.
- Attach and screw the needle to your KwikPen.
- Remove the big outer needle cap.
- Remove the inner needle cap.
- Turn the dose selector to two units.
- Hold your KwikPen with the needle pointing up.
- Use your finger to gently tap the cartridge window to move the air bubbles to the top of the cartridge—which is near the needle.
- Continuing to hold your KwikPen with the needle pointing up, press the push-button on the other end of the KwikPen for five seconds. You should see the dose selector return to zero and a drop of insulin on the needle tip.
- If you don’t see a drop of insulin on the needle tip, remove this needle, replace it with a new needle, and follow steps 1 through 11 again. Repeat step 12 until you see a drop of insulin on the needle tip. If you don’t see a drop of insulin on the needle tip by the fifth attempt for the U-100 pen or the ninth attempt for the U-200 pen, don’t use this pen and call the manufacturer (Eli Lilly) at 800-545-5979. You can also reach out to your pharmacist for assistance.
- With the dose selector back at number zero, turn the dose selector again until you reach the number of units that you’ve been instructed to inject for your situation. Make sure that the pointer lines up with your dose in units.
- With one hand, gently pinch a fold of skin at your injection site. The need to pinch the skin will vary per person. Talk with your healthcare provider to discuss the necessity of pinching your skin.
- Using your other hand, hold your KwikPen with the needle at a 90 degree angle to the injection site. Be careful not to press the push-button yet.
- Continue to pinch a fold of your skin while inserting the needle into the injection site and pressing the push-button all the way in until the dose selector returns to zero. The pointer should be lined up to the number zero. Keep the needle in your skin for a minimum of five seconds.
- Gently stop pinching the fold of your skin and remove the needle. Make sure to hold the push-button until the needle is out of your skin. It is normal to see a drop of insulin on the needle tip.
- If you see blood after you remove the needle from your skin, use a piece of gauze to gently press down on your injection site. Don’t rub the area.
- Remove the needle from your KwikPen and throw it in one of the following containers: red biohazard (sharps) container, hard plastic container (e.g., detergent bottle), or a metal container (e.g., empty coffee can). For additional information on how to appropriately and legally throw away your syringes and needles, talk with your pharmacist.
- Place the cap back on your Humalog KwikPen.
After bringing Humalog home from the pharmacy, you’ll need to protect your insulin from heat and light. Also, avoid freezing insulin. You can place unused vials and pens in your refrigerator between 36 degrees and 46 degrees. These refrigerated and unused vials and pens will last until the expiration date on the container or packaging.
If you prefer to store your unopened vials or unused pens at room temperature, however, then these products will only last for 28 days. Once you open a Humalog vial, you can store it in your fridge or at room temperature. But you will need to throw it away after 28 days. Once you use a Humalog pen, on the other hand, you can only store it at room temperature. And after 28 days, you will also need to throw it away.
If your healthcare provider recommends diluted (watered down) Humalog U-100 for you to inject under your skin, your healthcare provider will help you dilute your insulin in an appropriate amount and type of liquid. This diluted Humalog U-100 will be in good condition for 28 days in your refrigerator at 41 degrees. If you’re going to store your diluted Humalog U-100 at 86 degrees—which is above room temperature, your insulin will expire in 14 days.
If you are going to travel with Humalog, familiarize yourself with the regulations of your final destination. Make a copy of your Humalog prescription and consider asking your healthcare provider for documentation of medical necessity on a letter with an official letterhead. Also, have the original packaging or container with your name on it—from your pharmacy.
If you are carrying empty syringes, make sure to have Humalog physically on your person. You may also want to have an insulated bag with cold packs to prevent your insulin from getting too hot.
How Long Does Humalog Take to Work?
Humalog lowers your blood sugar very quickly. The manufacturer recommends injecting this insulin within 15 minutes before or immediately after a meal.
What Are the Side Effects of Humalog?
Similar to other insulins, side effects are possible with Humalog.
This is not a complete list of side effects and others may occur. A healthcare provider can advise you on side effects. If you experience other effects, contact your pharmacist or a healthcare provider. You may report side effects to the Food and Drug Administration (FDA) at fda.gov/medwatch or 800-FDA-1088.
Common Side Effects
Common side effects with Humalog include:
- Lipodystrophy (abnormal fat distribution)
- Low blood sugar
- Reactions at your injection or insertion site (area where you inject or infuse your insulin)
- Swelling of your hands and feet
- Weight gain
Severe Side Effects
Seek immediate medical attention if you experience any of the following severe side effects:
- Extremely low blood sugar: If you’re experiencing severely low blood sugar, you may experience clumsiness, coma, confusion, seizures, and slurred speech. If your blood sugar is this low, use the glucagon product that your healthcare provider prescribed.
- Extremely high blood sugar: If your blood sugar gets too high, you can develop diabetic ketoacidosis, which is a life-threatening condition of high ketones due to fat breakdown in your body. Symptoms of ketoacidosis, include dry mouth, fruity-smelling breath, nausea, and vomiting.
- Heart failure: If you’re having heart failure, you might notice appetite loss, breathing problems, confusion, excessive sweating, and fast heart rate. You may also notice coughing and wheezing that don’t go away.
- Low potassium: If you have low amounts of potassium in your body, you may also have symptoms of abnormal heartbeat, constipation, muscle spasms, and numb or tingly sensations in your body.
- Severe allergic reaction: If you’re experiencing a severe allergic reaction, symptoms may include breathing problems, fast heartbeat, rash and sweating. You might also feel faint.
Long-Term Side Effects
Repeatedly using the exact same injection or insertion (infusion) spot raises your risk of lipodystrophy, which is an abnormal distribution of fat. This medical condition can lead to pitted-looking skin due to thinning of your fat tissue. It can also cause thick-looking skin due to the thickening of fat tissue.
Report Side Effects
Humalog may cause other side effects. Call your healthcare provider if you have any unusual problems while taking this medication.
If you experience a serious side effect, you or your provider may send a report to the FDA’s MedWatch Adverse Event Reporting Program or by phone (800-332-1088).
Dosage: How Much Humalog Should I Take?
Drug Content Provided and Reviewed by
The dose of this medicine will be different for different patients. Follow your doctor’s orders or the directions on the label. The following information includes only the average doses of this medicine. If your dose is different, do not change it unless your doctor tells you to do so.
The amount of medicine that you take depends on the strength of the medicine. Also, the number of doses you take each day, the time allowed between doses, and the length of time you take the medicine depend on the medical problem for which you are using the medicine.
For injection dosage form:
For diabetes mellitus:
- Adults and children 3 years of age and older—The dose is based on your blood sugar and must be determined by your doctor.
- Children younger than 3 years of age—Use and dose must be determined by your doctor.
- For diabetes mellitus:
Pregnant people: In reference to currently available data, there is no connection between using Humalog and negative effects on your unborn fetus. Uncontrolled diabetes, however, can raise your chance of miscarriage, preterm birth, stillbirth and delivery complications. Be sure to discuss any concerns with your healthcare provider.
Breastfeeding people: Data about the effect of Humalog on nursing babies are lacking. Discuss any questions that you may have about using Humalog while nursing with your healthcare provider.
Children: The FDA approved Humalog to treat type 1 diabetes in children. You can use Humalog as under-the-skin injections. You can also use Humalog U-100 in an infusion pump. The manufacturer of this medicine, however, hasn’t studied Humalog for use in children under 3 years old or in children with type 2 diabetes.
People with kidney or liver problems: People with kidney or liver problems have a higher risk of low blood sugar with Humalog. As a result, your healthcare provider may recommend closely monitoring your blood sugar and adjusting your insulin dose as needed.
Humalog is typically used 15 minutes before or right after a meal. If you remember your missed Humalog dose before or right after mealtime, then immediately inject your missed dose. If some time (e.g., more than one hour) has passed since your missed dose, you can usually wait until your next scheduled meal and dosing time.
If you’re using Humalog in your insulin pump, perform the following maintenance tasks as soon as you remember:
- Change the Humalog in your pump reservoir every week or if it’s been exposed to temperatures over 98.6 degrees.
- Change your infusion sets and infusion set insertions at least every three days.
- Rotate your insertion (infusion) site within your chosen body region every three days.
- If you’re using a Humalog 3 milliliter cartridge for your D-Tron pump, you will need to throw away your cartridge every seven days.
Don’t try to double up and use extra insulin to make up for missed doses.
Since next steps to take after a missed Humalog dose will vary per person, refer to your healthcare provider’s recommendations. If you still have questions or concerns, call your healthcare provider.
Do your best to work toward finding ways to regularly remember your Humalog doses and insulin pump maintenance tasks. Forgetting doses and insulin pump maintenance tasks can cause uncontrolled high blood sugar levels and side effects. Over time, these high blood sugar levels can result in diabetes-related complications—like amputations, eye problems, heart disease, kidney problems and stroke.
Overdose: What Happens If I Take Too Much Humalog?
If you accidentally use too much Humalog, you may experience low blood sugar symptoms—like fast heartbeat, hunger, irritability, sweating, and tremors. So, if your blood sugar isn’t too low, use the following “15-15 rule”:
- Eat or drink 15 grams of carbohydrates (carbs), which is a type of macronutrient in foods and drinks. The following are some examples of 15 grams of carbs: glucose tablets or gel tube—read the label to understand how many tablets or how much gel will equal 15 grams of carbs; half a cup of juice or regular soda; one tablespoon of sugar or honey; and hard candies or jelly beans—read the label to understand how many candies or jelly beans will equal 15 grams of carbs.
- Wait 15 minutes.
- Check your blood sugar.
- Keep repeating steps one through three until your blood sugar is above 70 milligrams per deciliter (mg/dL).
- Once your blood sugar is above 70 mg/dL, eat a small meal or snack to prevent your blood sugar from dropping again.
If you’re experiencing clumsiness, coma, confusion and seizures, then your blood sugar is too low for the 15-15 rule. You may need to use the glucagon product that your healthcare provider prescribed. Glucagon is a naturally occurring hormone that encourages your liver to release glucose (sugar) into the bloodstream.
Since extremely low blood sugar is also linked to low potassium, get medical help right away—even after using your glucagon prescription. You might need hospital observation until your blood sugar and potassium levels reach normal ranges again.
What Happens If I Overdose on Humalog?
If you think you or someone else may have overdosed on Humalog, call a healthcare provider or the Poison Control Center (800-222-1222).
If someone collapses or isn’t breathing after taking Humalog, call 911 immediately.

Never share insulin pens or cartridges with others under any circumstances. It is not safe for one pen to be used for more than one person. Sharing needles or pens can result in transmission of hepatitis viruses, HIV, or other bloodborne illnesses.
Your doctor will want to check your progress at regular visits, especially during the first few weeks you take this medicine. Blood tests may be needed to check for unwanted effects.
It is very important to follow carefully any instructions from your health care team about:
- Alcohol—Drinking alcohol (including beer and wine) may cause severe low blood sugar. Discuss this with your health care team.
- Other medicines—Do not take other medicines during the time you are taking insulin lispro unless they have been discussed with your doctor. This especially includes nonprescription medicines such as aspirin, and medicines for appetite control, asthma, colds, cough, hay fever, or sinus problems.
- Counseling—Other family members need to learn how to prevent side effects or help with side effects if they occur. Also, patients with diabetes may need special counseling about diabetes medicine dosing changes that might occur because of lifestyle changes, such as changes in exercise and diet. Furthermore, counseling on contraception and pregnancy may be needed because of the problems that can occur in patients with diabetes during pregnancy.
- Travel—Keep a recent prescription and your medical history with you. Be prepared for an emergency as you would normally. Make allowances for changing time zones and keep your meal times as close as possible to your usual meal times.
In case of emergency: There may be a time when you need emergency help for a problem caused by your diabetes. You need to be prepared for these emergencies. It is a good idea to:
- Wear a medical identification (ID) bracelet or neck chain at all times. Also, carry an ID card in your wallet or purse that says that you have diabetes and a list of all of your medicines.
- Keep an extra supply of insulin lispro and syringes with needles or injection devices on hand in case high blood sugar occurs.
- Keep some kind of quick-acting sugar handy to treat low blood sugar.
- Have a glucagon kit and a syringe and needle available in case severe low blood sugar occurs. Check and replace any expired kits regularly.
This medicine may cause a serious allergic reaction, including anaphylaxis, which can be life-threatening and requires immediate medical attention. Tell your doctor right away if you have a rash, itching, shortness of breath, swelling of the face, tongue, and throat, trouble breathing, or chest pain after you receive this medicine.
You may have some skin redness, rash, itching, or swelling at the injection site. If this irritation is severe or does not go away, call your doctor. Do not inject insulin lispro into a skin area that is red, swollen, or itchy.
Using this medicine together with other diabetes medicine (eg, pioglitazone, rosiglitazone, Actos®, Actoplus Met®, Avandia®) may cause serious heart problems or edema (fluid retention). Check with your doctor immediately if you are rapidly gaining weight, having shortness of breath, chest pain or discomfort, extreme tiredness or weakness, trouble breathing, uneven heartbeat, or excessive swelling of the hands, wrist, ankles, or feet.
Too much insulin lispro can cause hypoglycemia (low blood sugar). Low blood sugar can also occur if you use insulin lispro with another antidiabetic medicine, changes in insulin regimen (eg, insulin strength, type of insulin, injection site), delay or miss a meal or snack, exercise more than usual, drink alcohol, or cannot eat because of nausea or vomiting or have diarrhea. Low blood sugar must be treated before it causes you to pass out (unconsciousness). People feel different symptoms of low blood sugar. It is important that you learn which symptoms you usually have so that you can treat it quickly. Talk to your doctor about the best way to treat low blood sugar.
Symptoms of low blood sugar include anxiety, behavior change similar to being drunk, blurred vision, cold sweats, confusion, depression, difficulty in thinking, dizziness or lightheadedness, drowsiness, excessive hunger, fast heartbeat, headache, irritability or abnormal behavior, nervousness, nightmares, restless sleep, shakiness, slurred speech, and tingling in the hands, feet, lips, or tongue.
If symptoms of low blood sugar occur, eat glucose tablets or gel, corn syrup, honey, or sugar cubes, or drink fruit juice, non-diet soft drink, or sugar dissolved in water to relieve the symptoms. Also, check your blood for low blood sugar. Go to a doctor or a hospital right away if the symptoms do not improve. Someone should call for emergency help immediately if severe symptoms, such as convulsions (seizures) or unconsciousness occur. Have a glucagon kit available, along with a syringe and needle, and know how to use it. Members of your household should also know how to use it.
Hyperglycemia (high blood sugar) may occur if you do not take enough or skip a dose of your antidiabetic medicine or insulin, changes in insulin regimen, you overeat or do not follow your meal plan, have a fever or infection, or do not exercise as much as usual. High blood sugar can be very serious and must be treated right away. It is important that you learn which symptoms you have in order to treat it quickly. Talk to your doctor about the best way to treat high blood sugar.
Symptoms of high blood sugar include blurred vision, drowsiness, dry mouth, flushed, dry skin, fruit-like breath odor, increased urination, ketones in the urine, loss of appetite, stomachache, nausea or vomiting, tiredness, troubled breathing (rapid and deep), unconsciousness, and unusual thirst. If these symptoms occur, check your blood sugar level and then call your doctor for instructions.
This medicine may make you dizzy or drowsy. Do not drive or do anything else that could be dangerous until you know how this medicine affects you.
What Are Reasons I Shouldn’t Take Humalog?
The manufacturer recommends against using Humalog if the following applies to you:
- Your blood sugar levels are low.
- You have a severe allergic reaction to Humalog or any of its ingredients.
What Other Medications Interact With Humalog?
Use caution with the following medications:
- Medications that raise the risk for low blood sugar, such as sulfonamide antibiotics, such as Bactrim DS (sulfamethoxazole/trimethoprim)
- Medications that lower Humalog’s effectiveness and raise blood sugar levels, such as steroids (e.g., prednisone) and atypical antipsychotics, including Zyprexa (olanzapine) or Seroquel (quetiapine)
- Medications that heighten or dull Humalog’s effects, such as alcohol or lithium
- Medications that hide symptoms of low blood sugar, such as beta-blockers, such as Coreg (carvedilol)
This isn’t a complete list of medications that can interact with Humalog. For more detailed information about medications that interact with Humalog, talk with your pharmacist or healthcare provider.
What Medications Are Similar?
There are many different types of insulin. Humalog is a rapid-acting insulin, which is usually given around mealtime.
Other mealtime insulins include:
- Afrezza (inhaled insulin)
- Apidra (glulisine)
- Aspart products, such as NovoLog and Fiasp
- Human regular insulin products, such as Humulin R, Novolin R, or Myxredlin
- Other lispro products, such as like Admelog and Lyumjev
All of the above insulins are rapid acting except for the human regular insulin products, which are short acting. Compared to rapid-acting insulins that are given within 15 minutes of meals, short-acting insulins are given within 30 minutes of meals. While these two types of insulins are slightly different, these insulins have no differences in achieving blood sugar goals and lessening low blood sugar symptoms.
Additionally, unlike the rapid-acting insulins, some of the short-acting ones—like Humulin R and Novolin R—are available as over-the-counter (OTC) medications, which don’t require a prescription from your healthcare provider. As OTC products, the short-acting insulins might also be less costly than the rapid-acting insulins—even without insurance coverage.
Since all of these insulins are mealtime insulins, they’re not typically used together for diabetes. If you have any questions or concerns, talk with your pharmacist or healthcare provider.
Frequently Asked Questions
Where is Humalog available?
Humalog is available as a prescription from your healthcare provider. Many of your local retail pharmacies will carry Humalog in the refrigerator behind the pharmacy counter. If necessary, the pharmacy staff can also order this insulin for you.
How much does Humalog cost?
Humalog is a brand-name insulin product. So, it might be costly without insurance coverage. If cost is a concern, consider talking with your pharmacist or healthcare provider about switching to the generic version or changing to one of the OTC short-acting insulins. You can also reach out to the manufacturer for more information about discounts.
Will I need other insulins in addition to Humalog?
In addition to Humalog, many people also have a basal insulin to help them achieve their fasting blood sugar goals.
Basal insulin is another type of insulin that mimics the background (baseline) insulin in people without diabetes who typically release a certain amount of insulin 24 hours throughout the day regardless of what food or beverages they’ve had.
Fasting blood sugar is your blood sugar without any food for at least eight hours. Many people measure this blood sugar level in the morning after a full night of sleep without food.
Why can’t I turn the dose selector to my dose?
You can only give yourself up to 60 units with one injection from many of the KwikPens. For the Junior KwikPen, however, this pen will only allow up to 30 units for one injection. If your healthcare provider recommended a dose higher than 60 units for most KwikPens or 30 units for the Junior KwikPen, then you will need to give yourself more than one injection.
Also, you cannot select a dose that is more than the number of units left in the KwikPen. So, if you need more units than what is left in your KwikPen, you can inject the amount that is left in this pen. Then, use a new pen to inject the rest of your dose. Another option is to throw away the used KwikPen—without a needle—in your regular trash and use a brand new pen to inject the full insulin dose.
Remember to use a new needle for each injection.
How Can I Stay Healthy While Using Humalog?
In addition to regularly taking or using your medications for diabetes, there are other ways to stay healthy, which include the following:
- Make sure to regularly check your blood sugar and perform next steps depending on the results and your healthcare provider’s recommendations.
- Eat a healthy diet.
- Have a regular exercise routine.
- Work toward achieving a healthy weight.
- Stay hydrated.
- Work with a registered dietitian nutritionist (RD/RDN), specifically one that is a Certified Diabetes Care and Education Specialist (CDCES). RDs/RDNs with a CDECES certification are specially trained to help people with diabetes to successfully manage their condition.
Maintaining a healthy lifestyle can help you have well-controlled blood sugar and prevent diabetes-related complications.
