How it works

Trimethoprim is an antibiotic that attacks the bacteria causing the infection in your bladder. It might be needed if your cystitis symptoms do not clear on their own after a few days.

Very effective at treating the bacterial causes of cystitis.

Can cause nausea, vomiting, diarrhoea or an allergic rash.

Collection

Trimethoprim is available for collection only. 

Taking Trimethoprim

If you currently have cystitis our doctors can prescribe a course of Trimethoprim to be taken immediately. You can pick up the medicine from one of our pharmacies the same day your order it.

You will take one tablet twice a day. After a couple of days, the bacterial infection in your bladder should clear up. If it does not, you should consult a doctor.

Does Trimethoprim treat the underlying causes of cystitis?

Yes. Trimethoprim is an antibiotic that kills the bacteria causing the infection in your bladder. Trimethoprim cannot permanently prevent future infections, however, it only treats infections when they occur.

Alternative Treatments

Our clinic does not offer any alternative treatments for cystitis. However, if your cystitis is only mild, you may find it clears up on its own after a few days. To help this process along, you should drink plenty of water, take over-the-counter painkillers to help with the discomfort and refrain from sexual intercourse.
