Indications
ProAmatine (generically known as midodrine) is a medication used to treat symptoms of low blood pressure when standing, also known as orthostatic hypotension. Midodrine is a vasopressor and antihypotensive medication used to treat low blood pressure by stimulating nerve endings in blood vessels, causing the blood vessels to constrict and increase blood pressure.
Uses and Dosage
Midodrine is usually taken three times a day, during daytime hours at least 3 hours. Take the last daily dose of midodrine before an evening meal and at least 4 hours before bedtime. Take midodrine at the same time every day and follow the instructions on your prescription label carefully. Only take midodrine as directed by your doctor, and do not change the dosage or frequency of your dose.
Midodrine is intended for use during waking hours when you are upright. Avoid taking a dose if you will be lying down for a long time. Talk to your doctor about proper positioning when lying down, which may involve elevating the head of your bed.
