  • 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.

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.

Trimethoprim 200mg tablets are available from THE Medical 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 our Online Doctor 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.

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.

Trimthoprim has a small risk of nausea, vomiting, diarrhoea, and skin rash as with all medicines. Please read the Patient Information Leaflet enclosed with your medicines for a full list of side effects.

If you experience any adverse effects from taking Trimethoprim 200mg tablets it is important to let us know immediately. Please log in to your online account and message one of our healthcare professionals or alternatively call us on 0117 332 69 90. In a medical emergency you should contact the emergency services or go straight to your local Accident & Emergency.

Trimethoprim 200mg tablets should not cause a harmful interaction with any of your other current medicines. It should not be taken if you currently take azathioprine, ciclosporin, dapsone, digoxin, eplerenone, mercaptopurine, methotrexate, phenytoin, procainamide, pyrimethamine, repaglinide, rifampicin, or warfarin. This was checked during your online consultation. Please read the Patient Information Leaflet enclosed with your medicines for further information.

About Cystitis (UTI)

Cystitis (UTI) Background

THE Medical Online Doctor service allows women who require a supply of antibiotics for cystitis to have a private consultation with a doctor and receive the treatment they require in a safe and discreet manner.

Cystitis is an infection of the bladder causing pain and inflammation. It is also commonly known as a water infection, bladder infection or a urinary tract infection (UTI). It is caused by bacteria, usually from the anus, entering the urinary tract (urethra) and moving up to the bladder, causing infection.

The most common causes of cystitis are bacterial infection  - most commonly by caused the bacterium, E.Coli. The bacteria is more likely to enter the urethra during sex, if you wipe from back to front after using the toilet, when inserting a tampon or a contraceptive diaphragm. Bacteria in your bladder are more likely to cause an infection if there is a blockage in your urinary system, or there has been damage or irritation to your urinary system. 

Cystitis is most common in women than men, it is estimated almost all women will experience cystitis at least once in their life.  Around 1 in 5 of those that experience cystitis will suffer with it more than once, know as recurrent cystitis.

Cystitis is more common in women due to their shorter urethra, allowing bacteria to reach the bladder more easily. It is most common in women who:

  • Are pregnant
  • Are sexually active
  • Have been through the menopause
  • Are diabetic
  • Use a catheter
  • Have kidney problems

Cystitis (UTI) Symptoms

The most common symptoms of cystitis are: 

  • Burning, stinging or pain when you urinate
  • Feeling the need to urinate frequently
  • Only being able to produce small amounts of urine
  • Some pain behind the pubic bone or in the lower back

Other symptoms that may be present and indicate a more serious infection are:

  • Severe pain behind the pubic bone or in the lower back
  • Pain in the flanks (the sides of your lower back – where your kidney are located)
  • Nausea and vomiting
  • Fever (temperature over 38°C)
  • Blood in the urine

If any of the above symptoms are present you should consult a doctor as your infection may have moved up your urinary tract to your kidneys (called pyelonephritis) and require more serious treatment.

Urinary tract infections in children, men and the elderly should always be treated by their GP. In children sometimes the only symptom present may be fever, although they can also include not feeding/eating, sickness, increased sleep or incontinence (weak bladder). Symptoms may also be absent in the elderly but are more likely to include incontinence, confusion or fatigue.

It is important to know the difference between cystitis and thrush, two conditions that are often confused and mistreated by people who are self-medicating.

Cystitis (UTI) Diagnosis

Women who have had cystitis before that has been diagnosed and investigated by their GP, can self-diagnose their symptoms if they are similar to previously and there are none of the warnings symptoms present. 

It is very important that women who experience cystitis for the first time, as well as men and children, always consult their GP – it should not be self-treated.

Additionally, women should visit their GP if they:

  • Experience cystitis more than 3 times in a year for an investigation into the cause of recurrent cystitis.
  • Are pregnant or suspect they may be pregnant
  • Have a catheter inserted
  • Are experiencing any other the symptoms listed above that indicate their infection may be more severe including nausea, severe pain, fever or blood in the urine.
  • Are diabetic

Your GP can make an accurate diagnosis of your condition based upon your current symptoms and medical history. If necessary they will be able to take a urine sample and perform tests to aid a correct diagnosis. Cystitis can have similar symptoms to vaginal thrush and some sexually transmitted infections so a correct diagnosis is vital to successful treatment.

Cystitis (UTI) Treatment

Women who are able to self-diagnose their cystitis are able to purchase treatment without the need to visit their GP. The following treatment options are available: 

  • Urine alkylising sachets (cystitis sachets) – these help to make the urine less acidic reducing the stinging sensation when urinating. Examples include Cymalon, Cystopurin and Canesten Oasis.
  • Over the counter painkillers – normal painkillers such as paracetamol or ibuprofen can be used to reduce discomfort.
  • Antibiotics  - trimethoprim is available to purchase from our Online Doctor for women who have previously been diagnosed with cystitis by their GP. Trimethoprim is the first line antibiotic for treatment of simple cases of cystitis in women. They are taken twice daily in a short course of 3 days to clear up most simple cases of cystitis. Trimethoprim will normally improve the symptoms of cystitis with 24 hours and cure the condition within 72 hours. If the condition has not fully resolved once the 3 day course of cystitis is complete, or your symptoms have worsened, you should see your GP for further treatment and advice.

Women with cystitis should also adopt the lifestyle changes listed below in ‘Prevention’ to reduce symptoms and speed up recovery.

Cystitis (UTI) Prevention

Women who suffer with frequent cystitis should adopt the following preventative measures to reduce their chances of recurrent infection:

  • Drink plenty of water – this is though to help flush the bacteria causing cystitis through your system.
  • Avoid sex – whilst you are suffering with cystitis you should avoid sex as it can push more bacteria in to your urethra and make the infection worse.
  • Use plain soap – perfumed bubble baths, soaps and talcs can all trigger cystitis or make it worse.
  • Try to fully empty your bladder when you go to the toilet.
  • Don’t overfill your bladder – go to the toilet when you feel the need, try not to hold it in for prolonged periods placing stress on your bladder.
  • Wear cotton underwear – synthetic materials are less breathable and can increase the likeliness of cystitis.
  • Wear loose fitting bottoms made from breathable material.
  • Always wipe your genital area from front to back – this will avoid pushing bacteria towards your urethra and reducing the chance of infection.
  • Avoid food or drinks that make cystitis worse – these can include spicy foods, fruit juice, alcohol or coffee.
  • Urinate as soon as possible after sex  - this will help to flush out any bacteria that have been pushed into the urethra.
  • Have a shower instead of a bath – this reduces exposure to irritant chemicals added to baths.

Cranberry products may have some effect at reducing the occurrence of frequent cases of cystitis although the evidence is unclear as to their benefits.
