Selexipag Injection

WHY is this medicine prescribed?

Selexipag injection is used in adults who are taking selexipag tablets to treat pulmonary arterial hypertension (PAH, high blood pressure in the vessels that carry blood to the lungs) but are temporarily unable to take medications by mouth. Selexipag injection is in a class of medications called selective nonprostanoid IP prostacyclin receptor agonists. It works by relaxing the blood vessels in the lungs to allow blood to flow easily.

HOW should this medicine be used?

Selexipag injection comes as a solution (liquid) to be injected intravenously (into a vein). It is usually injected slowly over 80 minutes by a doctor or a nurse. It is usually given twice a day for as long as you are unable to take selexipag tablets by mouth.
