Can I take Alfugress and Rantac together?

Why this happens

Alfuzosin (Alfugress) is an alpha-blocker that relaxes muscles in the prostate and bladder neck, which can lower blood pressure. Ranitidine (Rantac) is an H2 blocker used for stomach acid. While they do not interfere with how each other is processed in the body (metabolism), their combined effect on the body could potentially lead to a mild drop in blood pressure.

It is generally safe to take these two medications together. To be safe, move slowly when getting out of bed or sitting up to avoid dizziness. If you feel very dizzy or faint, contact your doctor. Note: Ranitidine (Rantac) has been withdrawn in many countries due to manufacturing concerns; ensure your supply is current and prescribed by a healthcare professional.

Postural hypotension

This medicine can cause a sudden drop in blood pressure when you stand up, especially within the first few hours of taking the first dose. You may feel dizzy or faint; sit or lie down until the feeling passes.

Cataract surgery

If you are due to have eye surgery for cataracts, you must tell your surgeon you are taking this medicine. It can cause 'Intraoperative Floppy Iris Syndrome', which requires the surgeon to use a different technique to avoid complications.

Alcohol

Drinking alcohol while taking this medicine can increase the risk of feeling dizzy, lightheaded, or faint, especially when standing up. It is best to limit or avoid alcohol until you know how the medicine affects you.

Food (General)

You must take this medicine immediately after a meal (usually the same meal each day). Taking it on an empty stomach can significantly reduce how much of the medicine is absorbed by your body, making it less effective.
