Minoxidil may increase chest pain (angina) or cause other heart problems. It is important that you keep all appointments with your doctor so that you can be monitored for any symptoms or changes. If chest pain occurs or worsens while you are taking this medication, call your doctor immediately. Your doctor may prescribe other medicines as part of your minoxidil therapy. Do not stop taking these medications unless your doctor tells you to do so.
WHY is this medicine prescribed?
Minoxidil is used with other drugs to treat high blood pressure. It works by relaxing the blood vessels so that blood can flow more easily through the body.
This medication is sometimes prescribed for other uses; ask your doctor or pharmacist for more information.
HOW should this medicine be used?
Minoxidil comes as a tablet to take by mouth. It usually is taken once or twice a day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take minoxidil exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Minoxidil controls high blood pressure but does not cure it. Continue to take minoxidil even if you feel well. Do not stop taking minoxidil without talking to your doctor.
What SPECIAL PRECAUTIONS should I follow?
Before taking minoxidil,
- tell your doctor and pharmacist if you are allergic to minoxidil or any other drugs.
- tell your doctor and pharmacist what prescription and nonprescription medications you are taking, especially other medications for high blood pressure, diuretics ('water pills'), guanethidine, and vitamins.
- tell your doctor if you have or have ever had heart disease, a heart attack, pheochromocytoma, or kidney disease.
- tell your doctor if you are pregnant, plan to become pregnant, or are breast-feeding. If you become pregnant while taking minoxidil, call your doctor.
- if you are having surgery, including dental surgery, tell the doctor or dentist that you are taking minoxidil.
- you should know that this drug may make you drowsy. Do not drive a car or operate machinery until you know how it affects you.
- ask your doctor about the safe use of alcohol while you are taking minoxidil. Alcohol can make the side effects from minoxidil worse.
What SPECIAL DIETARY instructions should I follow?
Your doctor may prescribe a low-salt or low-sodium diet. Follow these directions carefully.
What should I do IF I FORGET to take a dose?
Take the missed dose as soon as you remember it. However, if it is almost time for the next dose, skip the missed dose and continue your regular dosing schedule. Do not take a double dose to make up for a missed one.
