Alfuzosin may cause a condition that affects the heart rhythm (QT prolongation). QT prolongation can rarely cause serious (rarely fatal) fast/irregular heartbeat and other symptoms (such as severe dizziness, fainting) that need medical attention right away.

The risk of QT prolongation may be increased if you have certain medical conditions or are taking other drugs that may cause QT prolongation. Before using alfuzosin, tell your doctor or pharmacist of all the drugs you take and if you have any of the following conditions: certain heart problems (heart failure, slow heartbeat, QT prolongation in the EKG), family history of certain heart problems (QT prolongation in the EKG, sudden cardiac death).

Low levels of potassium or magnesium in the blood may also increase your risk of QT prolongation. This risk may increase if you use certain drugs (such as diuretics/"water pills") or if you have conditions such as severe sweating, diarrhea, or vomiting. Talk to your doctor about using alfuzosin safely.

This drug may make you dizzy. Alcohol or marijuana (cannabis) can make you more dizzy. Do not drive, use machinery, or do anything that needs alertness until you can do it safely. Limit alcoholic beverages. Talk to your doctor if you are using marijuana (cannabis).

Take this medication by mouth as directed by your doctor, usually once daily after a meal. This medication works best when taken with food. Taking alfuzosin on an empty stomach may make it not work as well.

Swallow the tablets whole. Do not crush or chew the tablets. Doing so can release all of the drug at once, increasing the risk of side effects.

Alfuzosin may cause a sudden drop in your blood pressure, which could lead to dizziness or fainting, usually within a few hours after you take it. This risk is higher when you first start taking this drug or if you restart treatment after you stop taking it. During these times, avoid situations where you may be injured if you faint.

To avoid injury from dizziness or fainting, your doctor may tell you to take your first dose of alfuzosin with food at bedtime so that your body can get used to its effects.

Take this medication regularly to get the most benefit from it. To help you remember, take it after the same meal each day.

Tell your doctor if your condition does not get better or if it gets worse.
