Product Overview

Loniten (minoxidil) is a medication primarily used for the treatment of severe or hard-to-treat hypertension (high blood pressure). It works by relaxing and widening blood vessels, allowing blood to flow more easily and reducing the strain on the heart. This FDA-approved medicine is recommended as a daily dosage of 5 mg for adults, given in two divided doses, with the possibility of gradually increasing the dosage based on blood pressure control. The starting dose for children under 12 years is 0.1 to 0.2 milligrams per kilogram of body weight per day.

Using Loniten under close supervision is essential, usually alongside a beta-adrenergic blocking agent to prevent increased heart rate and a diuretic to prevent fluid retention. Patients should be cautious of potential side effects such as rapid weight gain, difficulty breathing, and severe skin reactions.

Loniten is contraindicated in individuals with a history of hypersensitivity to any of its components, those with pheochromocytoma, and patients with pulmonary hypertension related to mitral stenosis. It should be stored at room temperature, away from light and moisture, and out of reach of children and pets. Before taking Loniten, patients should inform their healthcare providers about all other medications they are using to avoid potential drug interactions.
