The prescription drug Loniten lowers blood pressure by relaxing the blood vessels and improving blood flow. This medicine is only approved for treating severe blood pressure that is not adequately controlled with other medications and is causing damage to body organs. Loniten comes in tablet form and is taken once or twice daily. Possible side effects include headaches, dizziness, and vomiting.
Minoxidil, the active ingredient in Loniten, is also available in a liquid form (Rogaine®), which is applied topically to the scalp to promote hair growth. Loniten tablets should not be used in any way to stimulate hair growth. Making a liquid from Loniten and using it on the scalp could result in too much of the medication being absorbed into the bloodstream, leading to dangerous side effects.
