MONUROL is an antibiotic that fights infection caused by bacteria. MONUROL is used to treat bladder infections.

Proper Use of this medication

Follow all directions on your prescription label. Do not take this medicine in larger or smaller amounts or for longer than recommended.

MONUROL is usually given in only one dose. Do not take more than a single dose unless your doctor tells you to.

You may take MONUROL with or without food.

MONUROL is a powder medicine that must be mixed with water before using it. Do not take the dry powder without adding water.

Dissolve the powder in 3 to 4 ounces (1/2 cup) of cold water. Stir this mixture and drink all of it right away. To make sure you get the entire dose, add a little more water to the same glass, swirl gently and drink right away.

Do not mix MONUROL oral powder with hot water.

It may take 2 or 3 days before your symptoms improve.

Call your doctor if your symptoms do not improve within 3 days after treatment, or if you have a fever or any other new symptoms.

To be sure MONUROL is the right antibiotic for the type of infection you have, your urine may need to be tested before and after you take this medicine.

Store at room temperature away from moisture and heat. Keep the powder in its original package until you are ready to mix your dose.
