3 Proper Usage

Proper usage of Remodulin requires strict adherence to your doctor’s orders. The medicine is infused under your skin or into a vein by using a specialized pump. Instructions on the use of the pump are given by a nurse or other trained health professional.

Here are some points to consider:

Use exactly the same amount of the medicine as recommended by your doctor. The instructions for preparation of the medicine and use of the pump are given by your doctor or nurse.

Remodulin is continuously infused using a portable pump. To ensure continuous infusion, you have to clearly understand how to use a particular type or model of the pump.

For subcutaneous (under the skin) infusion, the medicine must be infused through different sites in the body. The sites of infusion should be rotated to prevent injury to a specific part. It’s better to note down the infusion sites.

Make sure you know the authorized person to call in case any problem arises.

A second infusion pump is required when the first pump fails to function. Therefore, maintain a 24-hour backup pump.

If your doctor asks you to use this medicine for years, learn more about the chronic treatment from him/her.

Dosing: For best results, follow your doctor to know what amount of medicine you should take in a single dose. The doses of a medicine can differ according to the conditions for which it is being prescribed.
