If you’re experiencing cystitis, a three-day course of antibiotic treatment with nitrofurantoin can be an effective way to clear it up.
Cystitis is usually caused by a bacterial infection irritating the bladder. As an antibiotic, nitrofurantoin works by killing the bacteria that cause the infection. Your symptoms should improve within two days of starting treatment.
If we prescribe cystitis treatment, you would take one capsule twice a day for three days.
It’s unusual to experience side effects with nitrofurantoin. It’s possible that you might feel sick or dizzy. If this happens to you, do not drive or operate heavy machinery.
For the full information on side effects and how to take nitrofurantoin safely, it’s important to read the Patient Information Leaflet that comes with your medicine.
This service is for women, 18-64 years only.
If you suffer from cystitis repeatedly you should see your GP to work out your best treatment option.
It’s important that you tell us which other medicines you’re taking – whether they’re prescription or medicines you’ve bought without a prescription. You must also tell us about any other medical conditions. We need to know so that we only prescribe nitrofurantoin if suitable for you.
If you’re pregnant or breastfeeding you should not use this service. Please see your GP for a face-to-face appointment.
Cystitis may clear up without an antibiotic, within five days. But we advise you get treated after two days if your symptoms are unpleasant.
Other healthcare providers may prescribe a different antibiotic or therapy.
