Trimethoprim 200mg tablets are available from The Independent Pharmacy Online Doctor service, following a free consultation, for the treatment of simple cystitis. To find out more about cystitis and see all the available treatments, see Cystitis page.
Trimethoprim 200mg tablets are antibiotics that are mainly used to treat urinary tract infections (also known as UTI's, cystitis, bladder infections or water infections). Trimethoprim is effective in around 9 out of 10 simple cystitis cases and will help to cure the infection in a couple of days. For most uncomplicated cases of cystitis, Trimethoprim 200mg tablets should be taken twice daily, one tablet every 12 hours until the prescribed course is complete. You should start taking Trimethoprim as soon as you feel the onset of cystitis symptoms.
Most cases of cystitis or UTIs are caused by E.coli, which originates in your gut. Trimethoprim does not kill E.coli, however, it stops bacterial DNA synthesis meaning it cannot replicate. This allows your immune system to destroy the infecting bacteria until they are gone and your infection is resolved.
Trimethoprim is not affected by food or alcohol so there is no need to alter your diet whilst taking it. Trimethoprim can be safely taken with other over-the-counter cystitis treatments, such as Cymalon & Cystopurin, which help to reduce the acidity of the urine. You can also take simple painkillers such as paracetamol, alongside Trimethoprim with no problems.
Your symptoms will normally improve within 24 - 48 hours of taking Trimethoprim 200mg tablets. You should always complete the course, even if you feel better. If your prescribed Trimethoprim 200mg tablets have not improved your symptoms after the three-day course, you should see your GP. This may suggest that your UTI is resistant to Trimethoprim or that your symptoms are caused by something other than a bacterial infection, which requires investigation.
Trimethoprim can also be used to prevent cystitis at a dose of 100mg at night. You would need to see your GP to discuss recurrent bouts of cystitis to see if Trimethoprim 100mg tablets are suitable.
- Take one Trimethoprim 200mg tablet twice daily, roughly 12 hours apart.
- You should always continue the course until it is complete unless otherwise directed by a doctor.
- You should start taking Trimethoprim 200mg tablets as soon as you recognize the symptoms from cystitis that has previously been diagnosed by your GP.
- You should see your GP if no improvement in your symptoms once the course is complete.
If you notice blood in your urine, or suffer with fever, chills, back pain, or vomiting your infection may be more serious and you should see your GP as soon as possible.
If you find that you have suffered with cystitis more than 3 times in one year you should see your GP for an investigation into the cause of your recurrent infections.
It is possible that you may be allergic to Trimethoprim. If you know you are allergic to Trimethoprim or have suffered a reaction previously do not take Trimethprim and discuss alternatives with your GP.
