Can I drink alcohol while taking Doxazosin?

Alcohol reduces blood pressure. Drinking alcohol while taking these tablets can cause the blood pressure to drop (hypotension). Therefore, drinking alcohol while taking these tablets is not recommended, at least in the initial days.

What drugs do I need to avoid while taking Doxazosin tablets?

Some drugs that can interact with Doxazosin are;

  • Blood pressure-lowering drugs
  • Ketoconazole
  • Erectile dysfunction drugs
  • Anti-inflammatory drugs

This list is incomplete. Always tell your doctor or pharmacist if you are using medication.

What should I do in case of a missed Doxazosin pill?

If you forget to take a pill, wait for the next pill and take it as usual. It would help if you never used double doses in any case.

How effective are Doxazosin tablets for blood pressure?

These tablets are very effective, and 76% of patients in one study have shown satisfaction. Those who did not fine effectiveness usually require more than one drug (combination therapy) to treat their hypertension.

Can I stop using Doxazosin after my blood pressure returns to normal?

You need to continue using the Doxazosin tablets even if your blood pressure has become normal. Leaving will cause the blood pressure to go high again.

What would happen if I had taken too many Doxazosin tablets?

In case of overdosing, your blood pressure will drop, and you will develop the symptoms of hypotension. You should immediately call the doctor.
