Most people with high blood pressure do not feel sick. If you are taking this medication for high blood pressure, keep taking it even if you feel well. To help you remember, take it at the same time(s) each day. Use this medication regularly in order to get the most benefit from it. Take your first new dose at bedtime when your dose is increased unless directed otherwise by your doctor. This will decrease the possibility of fainting. You should take this first dose as you are going to bed. To reduce your risk of fainting, the first dose prescribed by your doctor will be the smallest dose available. Prazosin can occasionally cause sudden fainting after the first dose and anytime that your dose is increased. The dosage is based on your age, medical condition and response to therapy. If stomach upset occurs, take with food or milk. Take this medication by mouth with or without food, usually two or three times daily or as directed by your doctor.
