About this medication
Minoxidil belongs to the general class of medicines called antihypertensives. It is used to treat high blood pressure (hypertension). High blood pressure adds to the workload of the heart and arteries. If it continues for a long time, the heart and arteries may not function properly. This can damage the blood vessels of the brain, heart, and kidneys, resulting in a stroke, heart failure, or kidney failure. High blood pressure may also increase the risk of heart attacks. These problems may be less likely to occur if blood pressure is controlled. Minoxidil works by relaxing blood vessels so that blood passes through them more easily. This helps to lower blood pressure. Minoxidil has other effects that could be bothersome for some patients. These include increased hair growth, weight gain, fast heartbeat, and chest pain.

However, improper use of liquids made from minoxidil tablets can result in minoxidil being absorbed into the body, where it may cause unwanted effects on the heart and blood vessels. Minoxidil is available only with your doctor's prescription. This product is available in the following dosage forms:
