Please note that the first line treatment for cystitis that is caused by a bacterial UTI is Nitrofurantoin, as there is quite a high bacterial resistance to Trimethoprim. Therefore it is wise to only use Trimethoprim to treat a UTI after a urine test has confirmed that the bacterial strain causing the infection is sensitive to Trimethoprim. Please note that this treatment is currently only offered for female patients. If you are male and are experiencing symptoms of a urinary tract infection, you should visit your GP or a sexual health clinic as this could be a sign of another infection or a more serious underlying problem.

Note: You must complete a short online consultation so that our doctor can ensure that the treatment is suitable for you. The above pricing should only be used as a reference. The final decision to issue this treatment lies with the prescribing doctor.

What is Trimethoprim?

Trimethoprim is an antibiotic medication commonly used for bladder infections and urinary tract infections – the most common being cystitis. It treats the infection while reducing uncomfortable symptoms quickly.

We offer Trimethoprim in 100mg and 200mg doses:

  • the 100mg dose is used on a long-term basis to prevent infections if you suffer from cystitis regularly
  • the 200mg dose is used as needed to treat one-time infections

How does Trimethoprim work?

Trimethoprim is an antibiotic that works by preventing the bacteria that causes the infection from producing folate, which is what it needs to survive and multiply. Without this, the bacteria cannot spread, which allows the immune system to destroy the infection.

How do I take Trimethoprim?

This medication should be taken as directed by your doctor.

Trimethoprim is available from euroClinix as 100mg and 200mg tablets.

For a one-time infection, the usual dose is Trimethoprim 200mg, which needs to be taken twice a day for 3-14 days to effectively clear the infection.

When used long term as a preventative treatment, 100mg tablets are usually prescribed.

Tablets should be swallowed whole with a glass of water, and they can be taken with or without food.

Usually a short course of Trimethoprim will completely treat the infection. However, sometimes, a longer-term treatment is needed to avoid a reappearance.

It is important to take antibiotics exactly as instructed. Even if your symptoms improve quickly, you should always finish the entire course of medication. Not only could your infection come back if you stop taking them too soon, but bacteria can build up resistance to antibiotics, which will make them less effective at treating infections in the future.

You should always read the patient information leaflet thoroughly before beginning any new medication. You can find the patient information leaflet at the bottom of this page.

Trimethoprim and alcohol

While you can drink alcohol while on Trimethoprim, it is not recommended. You should drink plenty of clear liquids and refrain from drinking alcohol if you are using it to treat a urinary tract infection or cystitis.

Trimethoprim doses

You can purchase Trimethoprim 100mg and 200mg from euroClinix. The 200mg Trimethoprim course of tablets is usually recommended for a one-time infection and is taken for a maximum of two weeks.

The 100mg dose of Trimethoprim is usually prescribed for those who need a long-term preventative treatment of the infection.

What precautions should I take?

Trimethoprim is a commonly used antibiotic that is widely tolerated by most people. However, you should not take it if you:

  • are allergic to any of the ingredients
  • are pregnant or breastfeeding
  • have severe kidney or liver problems
  • have a blood disorder, like anemia

Ask a doctor before taking if you:

  • have kidney problems
  • have a folic acid deficiency
  • are at risk of hyperkalaemia (high blood potassium)
  • are taking repaglinide
  • have a disorder called porphyria
  • have an intolerance to some sugars

You should detail all medical information and any medication you are taking during your consultation, as some antibiotics may react negatively with other medications.

Trimethoprim side effects

As with all medications, it is possible that you may experience side effects, although not everyone will get them.

For those who do get side effects, the most common include:

  • feeling sick
  • diarrhoea
  • headache
  • itching or mild skin rashes

These will likely disappear once you have completed the course.

While most side effects are mild and short-lived, if you think you may be experiencing more serious side effects, you should seek immediate medical attention.

Read the patient information leaflet for a full list of side effects.

Where can I buy Trimethoprim online?

If approved, your prescription will be sent to our pharmacy. All orders made before 4:30pm are sent with fee overnight delivery, so you can feel better sooner.
