Why is this medication prescribed?

For the treatment of migraine headaches (severe, throbbing headaches that can occasionally be accompanied by nausea and sensitivity to light or sound), galcanezumab-gnlm injection is utilized. The signs of a cluster headache, which are severe headaches that typically affect one side of the head or the area surrounding one eye, are also treated with it. The drug galcanezumab-gnlm is a member of the monoclonal antibody drug class. It functions by preventing the body’s natural material from acting in a way that results in migraine headaches.

How should this medicine be used?

Galcanezumab-gnlm injection is available as a solution (liquid) in prefilled injection pens and syringes for subcutaneous (under the skin) injection. For the initial dose, galcanezumab-gnlm injection is often administered as 2 separate injections using a prefilled injectable pen or syringe given one after the other, followed by 1 injection once a month. Galcanezumab-gnlm injection is typically administered as 3 consecutive injections with a prefilled syringe given one after the other for the initial dose and subsequently 1 injection once a month to treat cluster headaches. Use an injection of galcanezumab-gnlm on or about the same day each month. If there is anything you do not understand about the instructions on your prescription label, contact your doctor or pharmacist to clarify it. Exactly as prescribed, administer galcanezumab-gnlm injection. Use only as directed by your doctor, either in the recommended amount or frequency.

You might be able to administer the medication yourself at home, or you might ask a friend or family member to do it for you. Ask your doctor to demonstrate how to inject the medication to you or the person giving the shots.

Both a prefilled syringe and a prefilled injection pen are available for the drug galcanezumab-gnlm injection. Before injecting the medication, let the syringe or injection pen warm to room temperature for 30 minutes away from direct sunlight. Never attempt to reheat the drug by putting it in a hot water bath, microwave, or any other device. Only administer each injection once, and use the entire amount of liquid in the syringe or injection pen. Put used syringes or injectable pens in a container that won’t puncture. How to get rid of the puncture-resistant container should be discussed with your doctor or pharmacist.

Galcanezumab-gnlm should be injected into the buttocks, stomach, back of the upper arm, or thigh. Avoid injecting into areas of skin that are soft, thick, bruised, red, scaly, or hard.

Before injecting galcanezumab-gnlm, always check the solution. The solution should be clear, colorless, barely yellow or barely brown. If the injection of galcanezumab-gnlm is hazy or contains flakes or solid particles, do not use it. Never shake it.

The injection galcanezumab-gnlm aids in migraine prevention but does not treat it. Even if you feel well, continue administering the galcanezumab-gnlm injection. Stop using galcanezumab-gnlm injection only after seeing your physician.

What special precautions should I follow?

Before using galcanezumab-gnlm injection,

  • Inform your doctor and pharmacist about any additional prescription and over-the-counter drugs, vitamins, dietary supplements, and herbal products you are now taking or intend to use. Your physician might need to adjust the dosage of your drugs or keep a close eye on you for side effects.

What special dietary instructions should I follow?

Keep eating normally unless your doctor instructs you otherwise.

What should I know about storage and disposal of this medication?

Keep this medication tightly closed in the original container and out of the reach of children. Do not freeze it; instead, keep it in the refrigerator. The drug can be stored at room temperature in the original carton for up to 7 days after being taken out of the fridge.

As many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and are simple for young children to open, it is crucial to keep all medications out of sight and out of reach of children. Always lock safety caps and promptly stash medication up and away from young children where it is out of their sight and reach to prevent poisoning.

Unused prescriptions must be disposed of carefully to prevent pets, kids, and other people from ingesting them. You should not, however, dispose of this medication in the toilet. Instead, utilizing a medicine take-back program is the easiest approach to get rid of your medication. To find out about take-back programs in your area, speak with your pharmacist or the garbage/recycling department in your city. If you do not have access to a take-back program, see the FDA’s Safe Disposal of Medicines website at for additional information.

In case of emergency/overdose

Call the poison control hotline at 1-800-222-1222 in the event of an overdose. Additionally, information can be found online at Call 911 right once if the person has collapsed, experienced a seizure, is having difficulty breathing, or cannot be roused.

What other information should I know?

Keep all of your doctor’s appointments.

Do not share your medication with anybody else. Any queries you may have regarding medication refills should be directed to your pharmacist.

You should keep a written record of every medication you take, including any over-the-counter (OTC) items, prescription drugs, and dietary supplements like vitamins and minerals. This list should be brought with you whenever you see a doctor or are admitted to the hospital. You should always have this information with you in case of emergencies.
