Information for Patients about BiDil®
BiDil is approved for use with other heart medicines to treat heart failure in black patients to improve survival, improve heart failure symptoms, and help patients stay out of the hospital longer. There is little experience in patients with heart failure who experience significant symptoms while at rest. Most patients in the clinical study of BiDil also received other heart failure medicines.

Tell your doctor about any allergies you have, especially if you're sensitive to nitrates, such as nitroglycerin tablets or isosorbide dinitrate (Isordil®). BiDil has a nitrate component, so you need to let your doctor know.

Tell your doctor if you're taking any erectile dysfunction or pulmonary hypertension drugs like Viagra® or Revatio™ (sildenafil), Levitra® (vardenafil) or Cialis® (tadalafil). Mixing these with BiDil may cause a sudden drop in blood pressure, fainting, chest pain, or heart attack.

Also tell your doctor if you are taking any medication to decrease blood pressure because when taken with BiDil, blood pressure may become too low.

It is possible you'll get headaches, especially at first, but they often lessen over time. For some patients, Tylenol® (acetaminophen) helps ease the discomfort. Keep your doctor posted on your headache progress and Tylenol use; he or she may want to adjust your dosage.

If you experience dizziness, call your doctor. Please make sure to tell your doctor about any of the signs or symptoms mentioned below or about any unusual events that worry you.

Drinking less fluids than your doctor recommends or losing fluid due to diarrhea, sweating, or vomiting may cause low blood pressure, lightheadedness, or fainting. If fainting occurs, stop taking BiDil and contact your doctor immediately.

Lightheadedness may occur when standing, especially after sitting or lying down.

If you experience any achy and/or swollen joints, unexplained fever for more than a few days, skin rashes, chest pain, prolonged weakness or fatigue (even after a good night's sleep), or any other unexplained signs or symptoms, make sure to tell your doctor as they may be signs of a serious medical condition.

You may also experience rapid heartbeat that could lead to chest pain or aggravate chest pain, or numbness or tingling in the hands or feet.

Headache and dizziness were the most frequent side effects experienced in studies with BiDil.  Other side effects included chest pain, weakness, nausea, chest infection, low blood pressure, sinusitis, palpitations, high blood sugar, runny nose, tingling, vomiting, impaired vision, high cholesterol, and rapid heart rate. 

You are encouraged to report negative side effects of prescription drugs to the FDA.  Visit or call 1-800-FDA-1088.
