Taking Nitrofurantoin

If you have a water infection, our GPs can prescribe Nitrofurantoin to be taken immediately.

The capsules should be taken twice daily with meals or milk and you should begin to see some improvement within 48 hours. You should see a doctor if your symptoms are not improving after 48 hours or if they continue for longer than three days.

Does Nitrofurantoin treat the underlying causes of urinary tract infections?

Yes. Nitrofurantoin is an antibiotic that kills the bacteria causing the bladder infection. It is the first choice medicine for treatment of uncomplicated urinary tract infections.  

Alternative Treatments

Nitrofurantoin has been recognised as the first choice antibiotic treatment for all UTIs by Public Health England. However, if for any reason Nitrofurantoin is not suitable, our GPs may prescribe Trimethoprim as an alternative treatment.

LloydsPharmacy Online Doctor is committed to providing excellent medical care to its patients and complying with clinical guidelines.

Mild symptoms of UTIs may also clear up on their own within a few days. You should drink plenty of water and refrain from sexual intercourse during this time. Over-the-counter painkillers can also be taken to help relieve pain or discomfort.
