Doxazosin, while effective in treating hypertension and benign prostatic hyperplasia (BPH), can cause several side effects. These vary in severity and frequency among individuals. Common side effects include dizziness, lightheadedness, and fainting, especially when standing up quickly. This is often due to a sudden drop in blood pressure (orthostatic hypotension). You should rise slowly from a sitting or lying position to minimize this risk.
Gastrointestinal Effects
Some people experience nausea, vomiting, or constipation. If these symptoms are severe or persistent, consult your doctor. Changes in bowel habits are relatively common and usually resolve as your body adjusts to the medication.
Other Potential Side Effects
Less common side effects include fatigue, headache, and swelling in the ankles or feet. In rare cases, more serious side effects like allergic reactions (rash, itching, swelling) or liver problems (yellowing of the skin or eyes) can occur. Seek immediate medical attention if you experience any severe or unexpected symptoms. Always inform your doctor about all medications you are taking, including over-the-counter drugs and supplements, to avoid potential drug interactions.
