Begin treatment with a low dose to minimize side effects. Common side effects include dizziness, lightheadedness, and fainting, especially when standing up quickly. These typically lessen with continued use but require cautious movement and potential adjustments to your daily routine. Stay hydrated.
Managing Side Effects
Dizziness and lightheadedness frequently occur, particularly during the initial phase of treatment. Rise slowly from sitting or lying positions. If you experience significant dizziness, contact your doctor. Avoid driving or operating machinery until you know how doxazosin affects you. Avoid alcohol, as it can worsen these effects.
Other Potential Side Effects
Less common side effects include nasal congestion, fatigue, and edema. In rare cases, more serious reactions like priapism (persistent erection), or severe allergic reactions may occur. Seek immediate medical attention for any severe reactions. Inform your physician of all current medications you are taking, including over-the-counter drugs and herbal supplements, to prevent drug interactions. Regular blood pressure monitoring is advised during treatment. Inform your doctor if you experience swelling in your ankles, feet, or legs.
Precautions
Doxazosin may lower your blood pressure. This should be monitored closely, particularly if you have heart problems or low blood pressure. It can interact negatively with certain medications, so provide your doctor with a complete medication history. Be aware that this medication can cause blurry vision or affect your ability to focus. Exercise caution while driving or operating heavy machinery.
Allergic Reactions
Severe allergic reactions are rare but possible. Signs include hives, rash, swelling of the face, lips, tongue, or throat. If this occurs, seek immediate medical help. If you experience any unusual symptoms or side effects, consult your physician immediately. The information provided here should not substitute professional medical advice.
