It is important not to confuse Loniten with Rogaine® (minoxidil). Rogaine is a liquid, topical medication applied to the scalp to stimulate hair growth. Although both of these medications contain minoxidil, they are not interchangeable. Do not use Loniten to stimulate hair growth. Liquids made from Loniten and applied to the scalp could cause too much minoxidil to be absorbed into the bloodstream, leading to potentially serious side effects.
