Drug Description


Monurol is prescribed for treating acute cystitis in women, a form of uncomplicated urinary tract infection commonly referred to as bladder infection. 

As an antibiotic, Monurol eradicates infection-causing bacteria within hours of ingestion. It remains effective in the bladder for over 3 days, persistently eliminating bacteria. 

Uses and Dosage 

Carefully read the accompanying medication guide and patient information leaflet of Monurol before the first use and with each prescription refill. Seek guidance from your doctor or pharmacist for any queries or additional information. 

Monurol comes in a powder form to be mixed with water for oral administration. Do not take the dry powder without adding water. 

Typically, this medication is administered as a single dose without regard to food intake. Refrain from taking more than one dose unless specifically instructed by your doctor. 

To properly take Monurol, follow these steps: 

  1. Empty the entire contents of the sachet into 3 to 4 ounces of cold water (½ cup). 
  2. Stir to dissolve and consume the entire mixture right away. 
  3. To ensure a complete dosage, add a small amount of water to the same glass, swirl gently, and drink promptly. 

For optimal results, take Monurol exactly as directed. 

Inform your doctor if your condition does not improve after 3 days or if it becomes worse.
