Alopecia Topical Minoxidil
BRAND NAME: Rogaine (Regaine - UK)
DRUG CLASS AND MECHANISM: Oral minoxidil, a medication that originally was used to treat high blood pressure, has been found to increase hair growth. This lead to the development of topical (solution applied to the skin) minoxidil. Topical minoxidil (Rogaine) has been shown to stimulate hair growth on the bald spot of the back of the head in men. In women, Rogaine can increase hair growth in the forehead areas. Minoxidil is in a class of drugs called hair growth stimulants.
PRESCRIPTION: yes
GENERIC AVAILABLE: no
PREPARATIONS: Solution 2%, 60cc bottles.
STORAGE: Should be stored at room temperature.
PRESCRIBED FOR: Rogaine is used to treat the bald spot in male pattern baldness. In females, it is used to treat diffuse hair loss or thinning on the scalp in the frontal areas.
DOSING: Rogaine has to be applied on the scalp at least twice daily and for at least four months to see results. Rogaine works less well in patients that are older, have larger areas of baldness, and have been bald for longer periods of time. Rogaine should be applied to a normal dry scalp only and left in place for at least four hours. Rogaine must be continued in order to maintain or increase the hair growth achieved.
DRUG INTERACTIONS: Oral minoxidil can cause a fall in blood pressure, an increase in the heart rate, and weight gain (fluid retention). An increase in the absorption of minoxidil from the scalp can occur in patients with inflamed or abnormal scalps, leading to side effects mentioned above. Patients with heart failure or significant coronary heart disease should avoid Rogaine because of these side effects. Rogaine's alcohol base can irritate the eyes. Rogaine should not be used with other topical medications because they may increase its absorption and side effects. Rogaine should be used with caution in those with high blood pressure.
PREGNANCY: Rogaine should not be used in pregnancy.
NURSING MOTHERS: Rogaine should not be used by nursing women.
SIDE EFFECTS: Skin side effects are seen at times with Rogaine, including irritation, itch, contact dermatitis, hives, swelling, and sensitivity.
