PAH Medication & Treatment Guide

Learn more about the different types of medications that can help manage your PAH symptoms.

There are a variety of medicines available to treat your pulmonary arterial hypertension. The medicines for PAH work in a few ways. Some allow blood to flow more easily through the arteries of your lungs. Others help your heart and lungs work better. The medications you take may be pills, inhaled, or subcutaneous meaning you receive a shot of the medicine delivered through a small continuous pump.  It is important to work with your PAH specialist, a lung doctor or a heart doctor with expertise in this disease, to determine the treatment plan that will work best for you.
