Read the Patient Information Leaflet if available from your pharmacist before you start taking alfuzosin and each time you get a refill. If you have any questions, ask your doctor or pharmacist.
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.
Do not crush or chew extended-release tablets. Doing so can release all of the drug at once, increasing the risk of side effects. Also, do not split the tablets unless they have a score line and your doctor or pharmacist tells you to do so. Swallow the whole or split tablet without crushing or chewing.
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 improve or if it worsens.
