Taking oral minoxidil can result in certain risks. One of these risks involves hypertrichosis, which is the term for unusual hair growth on other parts of the body. This happens because oral minoxidil affects the whole body systemically, and can thus lead to hair growth in places other than the scalp. However, it's important to note that this condition usually resolves itself within four months of stopping the treatment.
Another potential side effect is lower extremity edema, a condition characterized by the swelling of legs, ankles, and feet. Some women may also experience headaches, palpitations, and nausea when taking this medication.
While they are less likely to occur, there are other risks associated with oral minoxidil usage. These include pleural effusion, which is the buildup of fluid between the layers of tissue lining the lungs and chest cavity. Also, some women may experience hypotension, a condition marked by lower-than-normal blood pressure. This can lead to feeling light-headed.
