Cystitis is a troublesome condition arising from infection in the urine. It usually resolves quickly with antibiotic. Some women are prone to repeated episodes of cystitis. Men rarely suffer from cystitis and the treatment offered here is not for men.
- Cystitis is usually associated with burning and soreness when passing water (doctors call this dysuria)
- There is usually a need to pass water frequently, sometimes many times in an hour
- During a water infection it is usually not possible to delay passing urine when there is an urge to go (urgency)
Sometime the frequency of cystitis infections can be reduced by wearing natural fibre rather than synthetics next to the skin. Drinking plenty each day also helps to keep the bladder flushed and can help to reduce infections. Passing water after intercourse can help for women who tend to get infections after intercourse. These simple measures maybe helpful in preventing infection, although often they are not.
Doctors often can not find out why a woman is getting repeated episodes of cystitis. When a woman first starts having these infections tests are sometimes carried out. The tests are usually normal.
In some women cystitis is associated with recent intercourse or can be associated with stress. However, most water infections seem to start for no particular reason. If a woman has repeated episodes of cystitis, and the pattern of infection and symptoms are not changing, doctors usually just treat each infection as it arises with antibiotic.
Treating cystitis with trimethoprim
Trimethoprim will cure cystitis infections in about 60% to 85% of cases. The success rate varies from one part of the UK to another. Trimethoprim is the antibiotic doctors prescribe most frequently for cystitis (200mg every 12 hours for 3 days).
When Trimethoprim is ineffective, or not suitable, other antibiotic can be tried. During infection it also helps to drink plenty, about 4 litres or 5-6 pints a day. Citrate sachets, available from chemists, that de-acidify the urine, can also help.
Other antibiotics commonly used to treat cystitis include ciprofloxacin, norfloxacin, ofloxacin, co-amoxiclav (Augmentin), and nitrofurantoin. These antibiotics are sometimes a first choice or are an alternative to trimethoprim. They are not available from Dr Fox.
Service aimed at
Standby antibiotic treatment is only for those women who are prone to cystitis and have already been diagnosed with it in the past. You should only use this treatment if you are confident you know when you have cystitis.
Only take antibiotic if you have pain on passing urine, frequency of passing urine and blood in the urine, or severe symptoms.
This service is not for the treatment of cystitis that has already started. If cystitis symptoms have already started see a doctor face-to-face. This will guarantee there is no delay in starting treatment.
Response to treatment
Simple cystitis will improve greatly within 24 hours of starting antibiotics. If symptoms are not improving in the first 24 hours, or have not gone completely at the end of 3 days, medical advice is needed. If symptoms worsen rather than improve medical advice is needed straightaway.
Complications and cautions
Infection can travel up from the bladder into the kidney. This is known as pyelonephritis and requires urgent medical attention and sometimes hospital treatment.
Any of the following symptoms may indicate serious pylonephritis:
- Back pain (indication of possible infection in the kidney)
- Fever (high temperature, flushing, shivering, feeling hot and cold)
- Nausea and sickness and loss of appetite
- Generalised aching and flu-like feeling and collapse
All the above symptoms suggest something more serious than a simple cystitis and the need to seek medical advice straight away.
Trimethoprim side effects
Most people taking trimethoprim experience no, or very mild, side effects. There may be gastrointestinal upsets, such as indigestion, loose stools and rashes. If a rash develops trimethoprim should be stopped and medical advice sought.
To combat antibiotic resistance please:
- Only use antibiotics when needed
- Never share antibiotics
- Always complete course as instructed
- Take unused medicine to local pharmacy for disposal
