Please Note

All medication can cause side effects. We have only listed a few to be aware of. Details of all side effects, including rare side effects to be aware of, are listed in the patient information leaflet (PIL). When completing your medical questionnaire, it is very important that you answer the questions truthfully. This is to ensure your doctor has a full picture of your medical history before prescribing. List all medicines you are already taking, including non-prescription and herbal medicines.
Alternatives

Whilst some cystitis infections may clear up of their own accord, you can ease symptoms by drinking 2-3 litres a day to flush the bladder and by taking cranberry tablets which are available from your pharmacy. Nitrofurantoin is the first line treatment antibiotic available.
Looking after your medicine

Do not take medicines after the expiry date stamped on the pack. Keep all medicines out of the reach and sight of children.

Medicines are only intended to be used by the person they are prescribed for. Do not give your prescribed medicine to anybody else, even if they have the same symptoms as you. Medicines can be harmful if used by anybody other than the person they have been prescribed for.
