Insulin aspart

Insulin is a hormone that helps lower blood sugar levels. Insulin aspart is a fast-acting insulin that begins to work about 15 minutes after you inject it, reaches its highest effect in about 1 hour, and continues to work for 2 to 4 hours.

Insulin aspart is used to help control blood sugar in adults and children with diabetes mellitus. Insulin aspart is sometimes used along with a long-acting or intermediate-acting insulin.

Insulin aspart may also be used for reasons not mentioned in this medication guide.

Never share an injection pen, cartridge, or syringe with another person, even if the needle has been changed.

You should not use insulin aspart if you are allergic to it, or if you are having low blood sugar (hypoglycemia).

Insulin aspart is not approved for use by anyone younger than 2 years old, and should not be used to treat type 2 diabetes in a child of any age. Fiasp is for use only in adults.

Tell your doctor if you have ever had:

• liver or kidney disease; or
• low levels of potassium in your blood (hypokalemia).

Tell your doctor if you also take pioglitazone or rosiglitazone (sometimes found in combinations with glimepiride or metformin). Taking certain oral diabetes medicines while using insulin may increase your risk of serious heart problems.

Tell your doctor if you are pregnant or breastfeeding.

Follow your doctor's instructions about using insulin if you are pregnant or become pregnant. Controlling diabetes is very important during pregnancy, and having high blood sugar may cause complications for both the mother and the baby.

Get emergency medical help if you notice signs of an insulin allergy: redness or swelling at the injection site, an itchy skin rash all over your body, difficulty breathing, a fast heartbeat, feeling faint, or swelling in your tongue or throat.

Insulin aspart can cause serious side effects. Contact your doctor immediately if you experience:

• heart problems—swelling, rapid weight gain, or shortness of breath; or
• low potassium—leg cramps, constipation, irregular heartbeats, fluttering in your chest, increased thirst or urination, numbness or tingling, or muscle weakness or feeling limp.

Common side effects of insulin aspart may include:

• low blood sugar;
• weight gain;
• low potassium;
• swelling in your hands and feet;
• skin rash, itching, redness, or swelling; or
• thickening or hollowing of the skin at the injection site.

This is not a complete list of side effects; others may occur. Contact your doctor for medical advice about side effects. You can report side effects to the FDA at 1-800-FDA-1088.

Follow all directions on your prescription label and read all medication guides or instruction sheets. Use the medicine exactly as directed.

Insulin aspart is injected under the skin, or as an infusion into a vein. A healthcare provider will give your first dose and may teach you how to properly use the medication by yourself.

Your healthcare provider will show you where on your body to inject insulin aspart. Use a different place each time you give an injection. Do not inject into the same place two times in a row.

Do not inject insulin aspart into skin that is damaged, tender, bruised, pitted, thickened, scaly, or has a scar or hard lump.

After using Novolog, you should eat a meal within 5 to 10 minutes. Fiasp should be given at the start of a meal or within 20 minutes after starting a meal.

Read and carefully follow any Instructions for Use provided with your medicine. Ask your doctor or pharmacist if you do not understand these instructions.

Prepare an injection only when you are ready to give it. This medicine should be clear and colorless. Do not use the medicine if it has changed colors or has particles in it. Call your pharmacist for new medicine.

If you use an injection pen, use only the pen provided with your medicine. If you use this medicine with an insulin pump, do not mix or dilute insulin aspart with any other insulin. Change the medicine in the reservoir at least every 6 days.

Never share an injection pen, cartridge, or syringe with another person, even if the needle has been changed. Sharing these devices can allow infections or disease to pass from one person to another.

You may have low blood sugar (hypoglycemia) and feel very hungry, dizzy, irritable, confused, anxious, or shaky. To quickly treat hypoglycemia, eat or drink a fast-acting source of sugar (fruit juice, hard candy, crackers, raisins, or non-diet soda).

Your doctor may prescribe a glucagon injection kit in case you have severe hypoglycemia. Be sure your family or close friends know how to give you this injection in an emergency.

Also watch for signs of high blood sugar (hyperglycemia) such as increased thirst or urination.

Blood sugar levels can be affected by stress, illness, surgery, exercise, alcohol use, or skipping meals. Ask your doctor before changing your dose or medication schedule.

Insulin aspart is only part of a treatment program that may also include diet, exercise, weight control, blood sugar testing, and special medical care. Follow your doctor's instructions very closely.

Keep this medicine in its original container protected from heat and light. Do not draw insulin from a vial into a syringe until you are ready to give an injection. Do not freeze insulin or store it near the cooling element in a refrigerator. Throw away any insulin that has been frozen.

Storing unopened (not in use) insulin aspart:

• Refrigerate and use until expiration date; or
• Store at room temperature and use within 28 days.

Storing opened (in use) insulin aspart:

• Store the vial in a refrigerator or at room temperature and use within 28 days.
• Store the cartridge or injection pen at room temperature (do not refrigerate) and use within 28 days. Do not store the injection pen with a needle attached.

Use a needle and syringe only once and then place them in a puncture-proof "sharps" container. Follow state or local laws about how to dispose of this container. Keep it out of the reach of children and pets.

In case of emergency, wear or carry medical identification to let others know you have diabetes.

Since insulin aspart is taken before meals, you may not have a specific dosing schedule. Whenever you take insulin aspart, make sure to eat a meal within 5 to 10 minutes. Do not use extra insulin aspart to compensate for a missed dose.

Always keep insulin on hand. Get your prescription refilled before you run out of medicine completely.

Seek emergency medical help or call the Poison Help line at 1-800-222-1222. An insulin overdose can lead to serious low blood sugar (hypoglycemia). Symptoms include drowsiness, confusion, blurred vision, numbness or tingling in your mouth, trouble speaking, muscle weakness, clumsy or jerky movements, seizures (convulsions), or loss of consciousness.

Insulin can cause low blood sugar. Do not drive or operate machinery until you know how insulin aspart affects you.

Avoid medication errors by always checking the medicine label before injecting your insulin.

Do not drink alcohol or use medications that contain alcohol. Alcohol can cause low blood sugar and may interfere with your diabetes treatment.

Insulin may not work as well if you take other medicines at the same time. Some drugs can also reduce your symptoms of hypoglycemia, making it harder to know when your blood sugar is low. This includes both prescription and over-the-counter medicines, vitamins, and herbal products. Not all possible interactions are included here. Inform your doctor about all medicines you begin or stop.
