Drug

Minoxidil

Pronounced

"min-OX-ih-dill"

Uses

Minoxidil is used with other medications to treat high blood pressure (hypertension). Lowering high blood pressure helps prevent strokes, heart attacks, and kidney problems. Minoxidil works by relaxing blood vessels so blood can flow more easily.

Warning

Minoxidil may cause serious heart problems or worsen chest pain (angina). This medication is only used when other treatments have not worked well or cannot be taken.

Your doctor should direct you to also take other medications to reduce the side effects of minoxidil. These medications include a "water pill" (diuretic) to prevent the body from holding on to too much water and salt and a heart medication (such as a beta blocker including propranolol) to prevent the heart from working too hard or beating too fast.

Your doctor will follow you closely while you are taking this medication. Keep all regular medical and lab appointments.
