If you have diabetes, your doctor might suggest GlucaGen as a treatment option. It’s a prescription drug used for the following:

  • to treat severe hypoglycemia (low blood sugar) in adults and children with diabetes
  • to pause movement of the digestive tract in adults undergoing certain diagnostic tests

The active ingredient in GlucaGen is glucagon. (An active ingredient is what makes a drug work.) Glucagon belongs to a class of medications called glucose elevating drugs.

GlucaGen comes as a powder that you, a caregiver, or a healthcare professional will mix with sterile water to make a liquid solution. This solution is then given as one of the following:

While you may give yourself injections under your skin and into your muscle, only a healthcare professional may inject GlucaGen into your vein.

This article describes the dosages of GlucaGen, as well as its strength and how to take it. To learn more about GlucaGen, see this in-depth article.

Note: This article covers GlucaGen’s usual dosages provided by the drug’s manufacturer. But when using GlucaGen, always take the dosage your doctor prescribes.

This section covers standard GlucaGen, GlucaGen Diagnostic Kit, and GlucaGen HypoKit dosages and administration information. Before prescribing this medication, your doctor will go over dosage instructions specific to your needs.

What are the forms of GlucaGen?

GlucaGen comes in the following forms:

  • GlucaGen HypoKit: This kit contains 1 milliliter (mL) of sterile water in a syringe and 1 milligram (mg) of GlucaGen in a single-dose vial.
  • GlucaGen Diagnostic Kit: This kit comes with 1 mL of sterile water in a syringe and 1 mg of GlucaGen in a single-dose vial.
  • GlucaGen 1-mg single-dose vial

What strength does GlucaGen come in?

GlucaGen comes in one strength: 1 mg of the drug per 1 mL (1 mg/1 mL) of sterile water.

What are the usual dosages of GlucaGen?

Your doctor will usually start you on a low dosage of GlucaGen. But they may have you use more if your symptoms don’t improve after your first dose.

The information below describes dosages that are commonly used or recommended. But be sure to take the dosage your doctor prescribes for you. They’ll determine the best dosage to fit your needs.

Dosage for severe low blood sugar

The recommended GlucaGen HypoKit dosage for severe hypoglycemia (low blood sugar) is 1 mg/1 mL of sterile water. It’s injected as a single dose in one of the following ways:

If symptoms are not relieved after 15 minutes, a second 1-mg dose may be injected using a new kit.

Dosage for use with certain radiology exams

The recommended dosage for use with diagnostic tests varies depending on which part of the digestive tract your doctor needs to treat. After your doctor decides the correct dosage for your condition, they’ll inject it as a single dose.

The following chart shows recommended GlucaGen dosages for use with diagnostic tests. (Note that each mg of the drug comes in 1 mL of sterile water.)

Injection typeDosage to relax stomach or small intestineDosage to relax large intestine
Into a vein0.2 mg to 0.5 mg0.5 mg to 0.75 mg
Into a muscle1 mg1 mg to 2 mg

What’s the dosage of GlucaGen for children?

The dosage of GlucaGen for children is based on their age and body weight in kilograms (kg)*. Each dose is injected as a single dose in one of the following ways:

A second dose may be given using a new kit if the child’s symptoms don’t improve after 15 minutes.

The following table shows GlucaGen HypoKit dosage for children with severe low blood sugar:

Child’s weightGlucaGen HypoKit dosage
25 kg or more1 mg in 1 mL sterile water
Less than 25 kg0.5 mg in 0.5 mL sterile water
Unknown in children ages 6 years and older1 mg in 1 mL sterile water
Unknown in children ages 5 years and younger0.5 mg in 0.5 mL sterile water

* One kg equals about 2.2 pounds (lb).

Is GlucaGen used long term?

Yes, GlucaGen is usually used as a long-term treatment when prescribed for episodes of low blood sugar. If you and your doctor determine it’s safe and effective for you, you’ll likely use it long term.

Dosage adjustments

GlucaGen is usually injected as a one-time dose when used for diagnostic testing.

When GlucaGen is used to treat severe low blood sugar, you can inject a second dose 15 minutes after the first if the first dose doesn’t work well enough.

The dosage of GlucaGen your doctor prescribes may depend on several factors. These include:

  • the type and severity of the condition you’re using GlucaGen to treat
  • your age
  • your weight
  • the form of GlucaGen you’re using
  • how you’re injecting GlucaGen
  • how well your body responds to GlucaGen (see “Dosage adjustments” under “What is GlucaGen’s dosage?”)

Your doctor will prepare and inject the GlucaGen Diagnostic Kit or single-use vial if you’re using the drug for certain diagnostic tests.

If you’re using GlucaGen HypoKit to treat severe hypoglycemia (low blood sugar), you can follow these step-by-step instructions on the drug manufacturer’s website.

Once you are fully awake and able to eat or drink after receiving a GlucaGen injection, you should consume 15 grams (g) of fast-acting carbohydrates.

Recovery from severe low blood sugar may require help from others. So be sure to let a caregiver or others around you know about your GlucaGen HypoKit and how to use it.

For information on GlucaGen expiration, storage, and disposal, see this article.

Accessible drug containers and labels

If you find it hard to read the prescription label on your medication, tell your doctor or pharmacist. Some pharmacies may provide medication labels that:

  • have large print or use braille
  • feature a code you can scan with a smartphone to change the text to audio

Your doctor or pharmacist may be able to recommend pharmacies that offer these accessibility features if your current pharmacy doesn’t.

Do not use more GlucaGen than your doctor prescribes, as this can lead to serious side effects.

Symptoms of overdose

Symptoms caused by a GlucaGen overdose can include:

What to do in case you use too much GlucaGen

Call your doctor right away if you think you’ve injected too much GlucaGen. You can also call 800-222-1222 to reach the American Association of Poison Control Centers or use its online resource. But if you have severe symptoms, immediately call 911 (or your local emergency number) or go to the nearest emergency room.

The sections above describe the usual dosages provided by the drug’s manufacturer. If your doctor recommends GlucaGen for you, they’ll prescribe the dosage that’s right for you.

Remember, you should not change your dosage of GlucaGen without your doctor’s recommendation. Only take GlucaGen exactly as prescribed. Talk with your doctor if you have questions or concerns about your current dosage. Here are some examples of questions you may want to ask them:

  • Will eating my regular foods affect my GlucaGen dosage for my diagnostic test?
  • When will my child need to switch to an adult dosage of GlucaGen?
  • Is it safe to use more than two doses of GlucaGen within 24 hours?
