Minoxidil may cause serious heart problems, including worsening of chest pain. Minoxidil is usually given with beta-blockers to prevent certain heart side effects and with diuretics to prevent serious fluid build-up. If you have severe, uncontrolled high blood pressure or if you take guanethidine, you should only begin taking Minoxidil under direct medical supervision (eg, in a hospital). You will be monitored to prevent side effects, which may occur if your blood pressure lowers too much or too quickly.
Lowering high blood pressure in patients who do not respond to other therapy.
Minoxidil is a vasodilator. It reduces blood pressure by relaxing and dilating (widening) blood vessels. Blood flows more freely and at a lower pressure through dilated blood vessels.
