What is isoxsuprine (Vasodilan)?

Isoxsuprine is in a class of drugs called vasodilators. Isoxsuprine relaxes veins and arteries, which makes them wider and allows blood to pass through them more easily.

These actions may help treat the symptoms of conditions such as cerebral vascular insufficiency (poor blood flow to the brain), arteriosclerosis (hardening of the arteries), Raynaud's phenomenon, and other conditions involving poor blood flow in the veins and arteries.

Isoxsuprine may also be used for purposes other than those listed in this medication guide.

What are the possible side effects of isoxsuprine (Vasodilan)?

Stop taking isoxsuprine and seek emergency medical attention if you experience an allergic reaction (difficulty breathing; closing of the throat; swelling of the lips, tongue, or face; or hives).

Stop taking isoxsuprine and contact your doctor if you develop a rash.

Other, less serious side effects may be more likely to occur. Continue to take isoxsuprine and talk to your doctor if you experience

  • chest pain or an irregular heartbeat (call your doctor if this becomes bothersome);
  • nausea or vomiting; or
  • dizziness or weakness.

Side effects other than those listed here may also occur. Talk to your doctor about any side effect that seems unusual or that is especially bothersome. You may report side effects to FDA at 1-800-FDA-1088.
