Why is this medication prescribed?

Trofinetide is used to treat Rett syndrome (an inherited condition that causes severe developmental and nervous system problems) in adult and children 2 years of age or older. Trofinetide is an analog of glycine-proline-glutamate (GPE), a protein that occurs naturally in the brain. It is not known exactly how trofinetide works, but it may improve nerve function and structure.

How should this medicine be used?

Trofinetide is available as a liquid solution for oral use. It is often taken twice a day, either with or without meals, in the morning and the evening. Take trofinetide daily at approximately the same times. Pay close attention to the instructions on the label of your prescription and ask your pharmacist or doctor to explain anything you do not understand. Follow the directions on trofinetide exactly. Never take more or less of it, or take it more frequently than your doctor has instructed.

To measure and take your trofinetide solution dose precisely, use an oral syringe or dosing cup (a measuring device); do not use a regular spoon or cup. If your prescription does not come with an oral syringe or cup, ask your pharmacist for one.

Don’t take another dose of trofinetide if you throw up after taking it. The following day, stick to your usual dose schedule.

Your physician or pharmacist will provide instructions on how to administer trofinetide solution through a nasogastric (NG) tube if you have one.

Request a copy of the patient’s manufacturer’s information from your pharmacist or physician.
