How should I use fosdenopterin?
Follow all directions on your prescription label and read all medication guides or instruction sheets. Your doctor may occasionally change your child's dose. Use the medicine exactly as directed.
Fosdenopterin is given using an infusion pump attached to a catheter placed into a vein. A healthcare provider can teach you how to properly use the infusion pump by yourself.
You may need to keep a diary of the dates and times for each dose you give to your child. You may also need to record information about the specific vials and amounts of fosdenopterin you use each time. Take this information with you every time you take your child t the doctor.
Read and carefully follow any Instructions for Use provided with your medicine. Ask your doctor or pharmacist if you don't understand all instructions.
Fosdenopterin must be mixed with a liquid (diluent) before using it. When using injections by yourself, be sure you understand how to properly mix and store the medicine.
Do not shake the mixed medicine.
Prepare an injection only when you are ready to give it. Each infusion should be finished within 4 hours after you mixed the medicine with the diluent.
Do not use if the medicine looks cloudy, has changed colors, or has particles in it. Call your pharmacist for new medicine.
Fosdenopterin doses are based on weight. Your child's dose needs may change if the child gains or loses weight.
Store unmixed fosdenopterin in a freezer. Keep each vial in its original carton and protect from light.
Take the medicine out of the freezer and let it reach room temperature for 30 minutes before mixing with the diluent. You may also warm the medicine in your hands for 3 to 5 minutes. Do not heat the medicine.
You may store mixed medicine in the refrigerator or at room temperature. If stored in a refrigerator, allow the mixture to reach room temperature before giving the injection. Complete the injection within 4 hours after mixing the medicine.
