Minoxidil Risks and Side Effects
Minoxidil (known in the U.S. as Rogaine), is a topical foam applied to the scalp to treat certain types of hair loss in both men and women. The drug, which was first used exclusively as an oral medication to treat high blood pressure, was found to cause increased growth and thickening of the hair, and has since become a highly popular treatment for those experiencing hair loss. Minoxidil stimulates hair growth and slows balding, and has been shown highly effective for people under the age of 40. It is unclear exactly how Minoxidil stimulates hair growth, but many suspect that Minoxidil’s dilation of the tiny blood vessels in the scalp, increases blood circulation to the follicles, thereby promoting growth. Like many topical medicines, Minoxidil can cause side effects, some of which are similar to the side effects experienced by those taking the oral treatment for hypertension.
Some users of Minoxidil may experience itching or skin rash, although uncommon. Rare Minoxidil side effects include acne at the application site, burning of the scalp, facial hair growth, inflammation at the hair root, red skin, facial swelling, and, in some users, increased hair loss. Minoxidil can also irritation of the scalp or may dry out the scalp, causing dandruff. The treatment can also make the scalp more susceptible to sunburn.
If the body absorbs too much Minoxidil, additional risks could occur, although these risks are rare. These Minoxidil risks include: vision changes or blurred vision, dizziness, lightheadedness, fainting, flushing, headache, numbness in the extremities, swelling in the face, hands or feet, and rapid weight gain. Topical Minoxidil, like its oral counterpart, can affect heart rate, heart rhythms, and blood pressure. If you experience any adverse side effects from Minoxidil, you should contact your doctor immediately.
There are a few additional precautions for those using Minoxidil. Pregnant or breast-feeding women should avoid exposure to Minoxidil. Additionally, if you are a cat owner, you should keep Minoxidil in a place where your cat cannot get into it. Minoxidil is highly toxic to cats (and also rats).
To minimize the risk of experiencing side effects with Minoxidil, avoid using multiple topical treatments on the scalp at once, or within a short time span. Hair coloring, permanents, or relaxers should be used after washing hair, and should be applied at least 24 hours before applying Minoxidil foam. You should also wash your hands after applying. Talk to your doctor before starting Minoxidil treatment. Discuss your allergies, current health conditions, and other medicines you are currently taking. It is also important to follow the dosing instructions, and not to apply more or more often than recommended by the manufacturer or your doctor.
If you are looking for a hair loss treatment, and are considering Minoxidil foam, speak with a hair loss specialist to find out if this medication is the right solution for you. Your doctor will be able to assess the kind of hair loss you are experiencing and determine if Minoxidil is a good solution, given your health history, allergies, and medications.
