Ganirelix (Fyremadel) is an injection that's given on certain days during the in vitro fertilization (IVF) process for people who have a hard time becoming pregnant. This medication is a gonadotropin-releasing hormone (GnRH) antagonist. It prevents your eggs from being released too soon before the egg retrieval step. Ganirelix (Fyremadel) is injected under the skin once daily during a certain number of days of the IVF cycle. Potential side effects include stomach pain, headache, and redness and swelling at the injection site.
Infertility (having trouble becoming pregnant)
Ganirelix (Fyremadel) is a gonadotropin-releasing hormone (GnRH) antagonist. It blocks GnRH, a hormone in the body that typically plays a role in preparing your body for ovulation (the release of an egg from your ovary). By blocking GnRH, ganirelix (Fyremadel) temporarily delays ovulation. This prevents the ovary from releasing eggs too soon before the egg retrieval procedure.

Generally well-tolerated
Comes as a ready-to-use prefilled syringe

The number of days you'll need to take ganirelix (Fyremadel) will depend on your particular IVF cycle and your situation. Follow your prescriber's directions very carefully to give the medication the best chance to help with the IVF process.
You can give yourself ganirelix (Fyremadel) injections at home. But you should have a healthcare professional teach you how to properly inject the medication before you do it yourself.
Always wash your hands with soap and water before you inject ganirelix (Fyremadel). Also make sure to wipe the area of skin you're going to inject the medication into with an alcohol swab before injecting. This will help prevent infections.
Inject ganirelix (Fyremadel) beneath the skin in the stomach area (at least 2 inches away from your belly button) or in the upper thigh. Use a different injection site each time. This will help prevent pain during injections and skin irritation.
To inject ganirelix (Fyremadel): Pinch your skin and insert the needle into the skin at a 45 to 90 degree angle. Press the plunger down slowly and steadily to inject the medication. Then, pull the syringe out quickly and hold a cotton ball against the injection area for several seconds.
You should use each ganirelix (Fyremadel) syringe only once. Never reuse them. Throw away the used syringe in a protective sharps container. Your prescriber might provide you with a sharps container. But if not, you can purchase one at most pharmacies. Don't throw syringes away in the regular trash since this can raise the risk for accidental needle-stick injuries.
Store ganirelix (Fyremadel) at room temperature away from light and heat. Don't put this medication in the refrigerator or freezer since this might damage it.
Ganirelix (Fyremadel) can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.
Risk factors: Latex allergy
Severe allergic reactions to ganirelix (Fyremadel) are possible, including life-threatening problems like anaphylaxis (closing of the throat). Get medical help right away if you notice hives, rash, swelling of the lips or tongue, or difficulty breathing after you take ganirelix (Fyremadel).
Some ganirelix (Fyremadel) products have a needle shield that contains natural rubber latex. If you have a latex allergy, you might have a higher risk of having an allergic reaction when you use ganirelix (Fyremadel). Let your prescriber know if you're allergic to latex before you start your injections. They might want you to inject the medication for the first time at their office in case you have a reaction to it.
You shouldn't take ganirelix (Fyremadel) if you're pregnant because the medication can cause harm to unborn babies if it's given during pregnancy. Because of this risk, your prescriber might ask you to take a pregnancy test before you start any fertility medications to make sure you're not pregnant. Tell your fertility specialist right away if you become pregnant during treatment with ganirelix (Fyremadel).
The typical dose is 250 mcg (the amount of medication in 1 prefilled syringe) injected under the skin once a day during a certain period of time in your IVF cycle. Your fertility specialist will tell you when to start and stop taking this medication.
Although certain medicines should not be used together at all, in other cases two different medicines may be used together even if an interaction might occur. In these cases, your doctor may want to change the dose, or other precautions may be necessary. Tell your healthcare professional if you are taking any other prescription or nonprescription (over-the-counter [OTC]) medicine.
Allergy to latex or dry natural rubber
Allergy to GnRH agonists, such as leuprolide
