Stendra is a prescription medication used
to treat erectile dysfunction in men. Stendra belongs to a group of drugs called phosphodiesterase
(PDE) inhibitors. These work by increasing blood flow to the penis during sexual stimulation.
This increased blood flow can cause an erection. This medication comes in tablet form and is
taken typically once a day, on an as needed basis, approximately 30 minutes before sexual
activity. Stendra can be taken with or without food. Common side effects of Stendra include headache,
flushing, and back pain.
