Loniten
Common Name:
minoxidil
How does Loniten work? What will it do for me?
Minoxidil belongs to a group of medications known as vasodilators. It is used to control severely elevated blood pressure that is not manageable with a water pill and two other blood pressure medications. After the first dose of minoxidil, blood pressure usually starts to go down within one-half hour.
High blood pressure increases the work of the heart, and it may damage the heart, kidneys, brain, and blood vessels if left for too long. Minoxidil works by relaxing the blood vessels so the blood passes through them more easily. This helps to lower blood pressure.

The recommended starting dose of minoxidil for adults is 5 mg given in 2 divided doses (i.e., 2.5 mg taken 2 times a day).
If the desired blood pressure is not achieved, your doctor may increase the dose to 10 mg daily after 3 days, 20 mg daily after an additional 3 days, and 40 mg daily after 3 more days. These are only guidelines. Some people may require higher doses to keep their blood pressure under control.
The dose for children less than 12 years of age is based on weight. The recommended dose is 0.2 mg per kilogram of body weight each day, divided into 2 equal doses and will be calculated by your doctor.
