How do I use this medicine?
Corifollitropin alfa is to be injected subcutaneously (into the fatty layer under the skin, preferably in the abdominal wall).

Your doctor or nurse will administer the injection for you. If you or your caregiver had been given the proper training on the preparation and injection techniques of this medicine, you or your caregiver may do the administration.

Use Corifollitropin alfa exactly as directed by your doctor or according to the instructions on the label. Do not administer more or less than instructed by your doctor.

Remember to rotate the injection sites. Do not inject into the same area all the time. New injection sites should be at least 1.5 inches away from the previous injection site. Do not inject near the navel (belly button).

Make sure you know how to use this medicine. If you have problems or do not understand the instructions, ask your doctor or pharmacist.

The dose and schedule of administration of Corifollitropin alfa will be decided by your doctor. Your doctor will advise you on the course of your treatment depending on your response to the medication.
What should I do if I have forgotten to use this medicine?
Ensure that you keep all appointments with your doctor so that you do not miss any doses. Your doctor also needs to regularly monitor your response to Corifollitropin alfa.

If you miss an appointment or miss an injection, alert your doctor or nurse. A replacement appointment or injection should be given as soon as possible.

Why is it important to keep my appointments with the doctor?

Keep your appointments with your doctor. Your doctor needs to monitor your condition and check your response to the medication regularly.
