Minoxidil is a vasodilator medicine and helps in lowering blood pressure by causing the blood vessels to dilate.

Remember not to confuse topical minoxidil with the oral one. Although it’s very much effective in patients with androgenic hair loss, it’s not clear if it’s of much help in alopecia areata (spot baldness).
Dosage and tips on how to use minoxidil include:
Note that minoxidil has less effect on old age patients. It also doesn’t work well in patients with large areas of baldness or the ones who have been bald for longer period of time. The use of Rogaine should be continued to increase the hair growth and to maintain the increase. See your doctor if you don’t see any increase in hairs after 4 months use.

Discuss with your doctor if you experience any of the side effects of Rogaine. The increase in dandruff and development of contact dermatitis is considered to be due to alcohol and propylene glycol in various preparations of topical minoxidil, used as vehicle for the main drug.

FDA has assigned pregnancy category C to minoxidil. Which means that the animal studies using oral minoxidil do not show the evidence of teratogenicity. However, reduced rate of conception and increased fetal absorption incidences were observed in animals (rabbits) who were given the medicine 5 times the usual oral dose for humans. Minoxidil oral and topical both should not be used in a pregnant woman. Among 4 reported cases of oral minoxidil exposure in human pregnancy, two of them were associated with congenital abnormalities, but due to the presence of severe hypertension in those patients and also the usage of other drugs to control it, makes it difficult to consider minoxidil as a teratogen, however possibility still exists. One patient experienced no side effect too.
Minoxidil is excreted into the breast milk. Due to the potential development of side effects while nursing infants, the drug should not be used in nursing women to avoid any adverse affects.
