Can I take Doxazosin and Ezetimibe together?

Why this happens

Doxazosin and ezetimibe work in completely different ways and are processed by different pathways in the body. Doxazosin relaxes blood vessels to lower blood pressure or improve urinary flow, while ezetimibe reduces the amount of cholesterol absorbed from food. They do not interfere with each other's absorption, metabolism, or excretion.

What you should do

You can continue to take both medications as prescribed by your doctor. As with any blood pressure medication like doxazosin, you should monitor for symptoms of low blood pressure, such as dizziness or lightheadedness, especially when starting treatment or increasing a dose.

Important precautions

First-dose hypotension

Doxazosin can cause a sudden drop in blood pressure, especially after the very first dose. This may make you feel dizzy or faint when standing up. It is recommended to take your first dose at bedtime to avoid falls.

Unexplained muscle pain - ezetimibe

Contact your doctor immediately if you experience unexplained muscle pain, tenderness, or weakness. While rare, this can be a sign of a serious muscle breakdown condition, particularly if you are also taking a statin.

Cataract surgery

If you are due to have eye surgery for cataracts, you must tell your surgeon you are taking doxazosin. It can cause a complication called 'Floppy Iris Syndrome' which the surgeon needs to prepare for.

Liver disease

You must not take ezetimibe if you have moderate or severe liver disease, or if you have unexplained changes in liver function tests.

Food and drink warnings

Alcohol

It is best to avoid or strictly limit alcohol while taking doxazosin. Alcohol can increase the blood-pressure-lowering effect of this medicine, which may make you feel dizzy, lightheaded, or faint, especially when standing up.

It is best to avoid or strictly limit alcohol while taking ezetimibe. Both alcohol and ezetimibe can affect your liver; combining them may increase the risk of liver damage or inflammation. If you have a history of liver disease, you should be particularly cautious.
