Can I take Aspirin and Doxazosin together?

Why this happens

Aspirin belongs to a group of medicines called NSAIDs. These can cause the body to retain salt and water and can affect certain chemicals (prostaglandins) that help keep blood vessels open. This can work against doxazosin, which is designed to relax blood vessels and lower blood pressure. Both drugs can also affect the lining of the stomach or the way blood clots.

For most people, taking an occasional low-dose aspirin (such as 75mg for heart protection) with doxazosin is fine. However, if you are taking higher doses of aspirin for pain or inflammation, you should monitor your blood pressure regularly. If you notice your blood pressure rising, or if you experience any unusual bruising, persistent stomach pain, or black, tarry stools, contact your doctor.

Asthma

Do not take aspirin if you have asthma that is worsened by aspirin or other non-steroidal anti-inflammatory drugs (NSAIDs), as it can trigger a severe or life-threatening asthma attack.

First-dose hypotension (fainting)

Doxazosin can cause a sudden, large drop in blood pressure when you first start taking it or when the dose is increased. Take your first dose at bedtime to avoid fainting or dizziness.

Stomach ulcers or bleeding disorders

Avoid aspirin if you have a history of stomach ulcers or bleeding problems, as it significantly increases the risk of serious internal bleeding.

Alcohol

Drinking alcohol while taking aspirin can increase the risk of irritation and bleeding in your stomach and intestines. It is best to limit alcohol intake or avoid it if you have a history of stomach ulcers.
