Nitrofurantoin 50mg capsules for cystitis

Burning when you pee and needing to go more often can be signs of a bladder infection. If you also have a fever, shivering, vomiting or pain in your side or back just below the ribs, seek urgent advice from your GP or NHS 111. These can be signs of a kidney infection and need a different assessment.

What will the prescriber ask?

In the UTI consultation, explain when your symptoms began and whether you have had similar infections or taken antibiotics recently. Tell the prescriber about pregnancy, kidney problems, allergies and medicines you use, including cystitis sachets.

Which capsules are in this pack?

Each capsule contains 50mg of nitrofurantoin. Check the strength and formulation on your prescription because 100mg modified-release capsules have a different dosing schedule. Follow your label for the dose and course length.

Seek medical advice if symptoms get worse or do not start to improve within 48 hours of starting treatment. Read the NHS guide to nitrofurantoin for more about taking the medicine and possible side effects.
