Pronunciation: GLOO-ka-gon

Common Brand Name(s): Glucagen

Important: How To Use This Information

This is a summary and does NOT have all possible information about this product. This information does not assure that this product is safe, effective, or appropriate for you. This information is not individual medical advice and does not substitute for the advice of your health care professional. Always ask your health care professional for complete information about this product and your specific health needs.

Uses

This medication is the same as your body's own glucagon, a natural substance that raises blood sugar by causing the body to release sugar stored in the liver. It is used to treat very low blood sugar (hypoglycemia) that may cause you to need help from others. To be ready ahead of time, make sure a family member or caregiver knows where you keep this medication and how to use it.

Glucagon may also be used before certain X-ray procedures of the gut. It slows down movement of the stomach, intestines, and colon, which may help make the X-ray more clear.

How To Use

Read the Patient Information Leaflet and Instructions for Use provided by your pharmacist when you get this medication and each time you get a refill. Keep this medication handy in case it is needed. If you have any questions, ask your doctor or pharmacist.

Caregivers should know the symptoms of low blood sugar (see also Precautions section) and be instructed on how to give glucagon if needed. An episode of very low blood sugar should be treated right away to prevent serious effects (such as brain damage).

Before using, check this product visually for particles or discoloration. If either is present, do not use the liquid. Learn how to store and discard medical supplies safely.

Inject this medication into a muscle or under the skin as directed by the doctor. The dosage is based on your age. Children's dosage is also based on their weight. After giving this medication, get medical help right away.

If the person is unconscious, turn the person on their side to prevent choking in case they vomit. If the person does not wake up after 15 minutes, another dose may be given, if available.

When the person wakes up and is able to swallow, give them a quick sugar source (such as glucose tablets, juice). Glucagon only works for a short time, and low blood sugar may return. Keep the blood sugar level up by eating snacks such as crackers, cheese, a meat sandwich, or milk.

Always call your doctor right away when an episode of very low blood sugar has happened. You may need more medical treatment, or your insulin dose and diet may need to be adjusted.

Side Effects

Nausea, vomiting, or headache may occur. Irritation, redness, or swelling at the injection site may also occur. If any of these effects last or get worse, tell your doctor or pharmacist promptly.

Remember that this medication has been prescribed because your doctor has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.

Tell your doctor right away if you have any serious side effects, including:

  • fast/pounding heartbeat

A very serious allergic reaction to this drug is rare. However, get medical help right away if you notice any symptoms of a serious allergic reaction, including:

  • rash
  • itching/swelling (especially of the face/tongue/throat)

This is not a complete list of possible side effects. If you notice other effects not listed above, contact your doctor or pharmacist.

Precautions

Before using glucagon, tell your doctor or pharmacist if you are allergic to it; or if you have any other allergies. This product may contain inactive ingredients (such as latex used in some products), which can cause allergic reactions or other problems. Talk to your pharmacist for more details.

Before using this medication, tell your doctor or pharmacist your medical history, especially of:

  • tumor of the pancreas (insulinoma)
  • adrenal gland problems (such as Addison's disease, pheochromocytoma)
  • not eating/poor eating habits
  • frequent low blood sugar

Low blood sugar (hypoglycemia) is more likely if you do not consume enough calories from food, or if you do unusually heavy exercise. Symptoms include sudden sweating, shaking, fast heartbeat, hunger, blurred vision, dizziness, or tingling hands/feet. It is a good habit to carry glucose tablets or gel to treat low blood sugar. If you don't have these reliable forms of glucose, rapidly raise your blood sugar by eating a quick source of sugar such as table sugar, honey, or candy, or drink fruit juice or non-diet soda. Tell your doctor right away about the reaction and the use of this product. To help prevent low blood sugar, eat meals on a regular schedule, and do not skip meals. Check with your doctor or pharmacist to find out what you should do if you miss a meal.

Tell your doctor if you are pregnant before using this medication.

It is unknown if this drug passes into breast milk, but it is unlikely to harm a nursing infant. Consult your doctor before breast-feeding.
