Prazosin Side Effects

Prazosin, frequently sold under the brand name Minipress, is a drug used for treating hypertension (high blood pressure). The use of Minipress may cause a variety of side effects based on the dosage and particular individual.

Identification

• Prazosin is considered an alpha-blocker which causes the blood vessels in the body to both relax and expand. In doing so, Prazosin effectively treats high blood pressure and enlarged prostate. Prazosin works by blocking the body's natural chemicals causing the constriction of vessels.

Common Side Effects

• The following less serious side effects may occur as a result of using Prazosin: dizziness and drowsiness, irregular urination, joint or muscle aches, nausea, vomiting, upset stomach, fatigue, headache, dry mouth, mild depression and nosebleed. Any persistent side effects from the above list require immediate medical attention as they may signal a more serious problem.

Serious Side Effects

• According to drugs.com, users of Prazosin have experienced a number of serious side effects including blurred vision, pounding heartbeat, puffiness of the extremities, chest pain and shortness of breath. Severe allergic reaction may also occur. Contact your doctor immediately in the case of any of these severe side effects.

Using Prazosin

• Prazosin can be taken with or without food, but the user should closely follow her particular prescription. Never take a double dose to compensate for a missed dose, instead skip the dose and continue on your regular schedule. Take with a full glass (8 oz.) of water and before bedtime to avoid dizziness and lightheadedness.

Warning

• Since Prazosin can cause dizziness and lightheadedness, be sure to sit up and stand slowly. Avoid alcohol as it can increase the intensity of certain side effects.
