Droxidopa is used to treat symptoms of low blood pressure when standing, caused by a certain medical condition (neurogenic orthostatic hypotension-NOH). This medication can lessen symptoms of low blood pressure when standing (orthostatic hypotension), such as dizziness, lightheadedness, or the "feeling that you are about to black out." Droxidopa is used by people whose daily activities are severely affected by this condition, even after other treatments are used (such as support stockings, water bolus). It is thought to work by making the blood vessels become more narrow, which increases blood pressure.

Take this medication by mouth as directed by your doctor, usually 3 times a day (morning, midday, and late afternoon). Swallow the capsules whole. You may take this medication with or without food, but it is important to choose one way and take this medication the same way with every dose. This drug is taken during daytime hours, when people stand most often. It should not be taken after the evening meal or less than 3 hours before bedtime.

The dosage is based on your medical condition and response to treatment. To reduce your risk of side effects, your doctor may direct you to start this medication at a low dose and gradually increase your dose. Follow your doctor's instructions carefully.

Tell your doctor if your condition does not improve or if it worsens.
