Trimethoprim 200mg is usually given to patients that are suffering from a urinary tract infection. It can be taken by both men and women, but the exact dosage depends on what type of UTI you have.
20mg trimethoprim generally comes in tablet form, but if you struggle to swallow tablets, you may be able to ask your own GP for an oral solution, which might need to be ordered in for you or made up by your local pharmacist.
Trimethoprim 200mg is usually taken twice a day, in the morning and in the evening, though dosages can vary depending on what you’re taking trimethoprim for.
Trimethoprim 200mg is currently only available in generic form, and not as a brand.
Trimethoprim is a safe medication when taken properly, but there are certain groups that need to be careful, as it could end up causing more harm than good in some cases. Examples of those that need to be careful include:
- Those that are allergic to trimethoprim
- Those with any type of blood disorder
- Pregnant women
- People with severe liver disease
- Those with kidney problems
- Anyone with a folic acid deficiency
If you belong to any of these groups of people and think that you may need to take trimethoprim, please contact your GP for more advice, as they may decide it isn’t suitable for you, or that you require additional monitoring whilst taking it.
Trimethoprim for kidney infection
Trimethoprim is sometimes prescribed to patients with a kidney infection. Sometimes, if a UTI is left without treatment, the infection can spread to the kidneys and cause more serious problems, hence why trimethoprim can still help with kidney infections.
If you suspect that you have a kidney infection or a UTI that’s been left untreated for too long, you should see your own GP urgently for a face to face consultation, as you may need to be referred for tests or given a different treatment. A kidney infection can be serious, so it’s important to get seen as quick as possible if you think you might have one.
Trimethoprim for acne
Trimethoprim is sometimes prescribed to treat acne in a similar way to other antibiotics such as lymecycline, minocycline and oxytetracycline. However, it isn’t one of the most commonly prescribed treatments for this condition, as many GPs will recommend a topical treatment first, followed by one of the other antibiotics mentioned before trialling trimethoprim.
Unfortunately, Doctor4U isn’t able to prescribe trimethoprim for acne, as you’ll need to see your own doctor if other treatments haven’t worked for you. This is because you may need to be referred to a specialist before being given a course of trimethoprim to try. If you need other acne treatments, please take a look at which treatments we’re able to offer here.
Trimethoprim for UTI
Trimethoprim is one of the most common treatments for cystitis, something that both men and women can experience.
If you think you need it, Doctor4U can prescribe trimethoprim for a UTI after you’ve completed some consultation questions for our doctors to review.
Trimethoprim works for UTIs by stopping bacteria from producing a protein called folate. Folate is needed for bacteria to produce DNA and multiply, so when folate is taken away, the bacteria dies, clearing the infection. When taking trimethoprim for a UTI, you should start to feel better within 24 hours of starting treatment, and the infection should clear up after 3 days, or however long your course of medication lasts.
Trimethoprim isn’t actually the first-choice antibiotic for many cases of cystitis now, as some bacteria has become resistant to it. Instead, doctors now offer nitrofurantoin as a first-line treatment, with the option to take trimethoprim if you have issues with the alternative. If you’d like to buy nitrofurantoin, please click here to read about the treatment.
Trimethoprim dose for UTI
For uncomplicated UTIs, the recommended dosage of trimethoprim is 200mg taken twice daily – one tablet in the morning and one tablet in the evening.
Trimethoprim tablets are normally prescribed for 3 days for uncomplicated UTIs, which should be long enough for your infection to clear. However, in some cases, your own doctor might recommend taking trimethoprim for up to 14 days. This may happen to you if you are a male, a pregnant woman, or have a severe or complicated UTI that wouldn’t be sufficiently treated with 3 days of antibiotics.
Doctor4U generally gives a 3-day course of trimethoprim to those that complete the consultation form for cystitis, but if you’re still experiencing symptoms after your course of treatment has finished, please see your own GP for a face to face consultation, as you may need to be referred for tests or given a different medicine such as nitrofurantoin.
Trimethoprim side effects
Trimethoprim is an antibiotic, and as with all antibiotics, it has the potential to cause adverse effects. Not everybody that takes trimethoprim gets side effects, and may that do find that they’re mild or easy to deal with. However, if the side effects of your medication outweigh the benefits, you should speak to your own doctor about trying a different treatment.
Some of the most commonly reported trimethoprim side effects include:
High blood levels of potassium
Skin rashes and itching
Agitation or abnormal behaviour
Tinnitus (ringing in the ears)
Low blood sugar levels
Joint and muscle aches
Shortness of breath
All side effects of trimethoprim are available in the patient information leaflet that comes with your order, and you should read it thoroughly before taking any of the medication.
Other, serious side effects may include:
- Anaphylactic shock
- Chest pain, fainting and collapse
- Blistering or peeling skin, skin lesions and swelling
If you get any of these side effects whilst taking trimethoprim, you should call 999 immediately.
You may be more at risk of experiencing side effects if you’re already taking one or more of the following medications:
Bone marrow depressants
Angiotensin II antagonists
If you’re already taking any of these medications, please speak to your GP before you buy trimethoprim, as it may not be suitable for you.
Best antibiotic for UTI
Currently, doctors prefer to offer nitrofurantoin as an antibiotic for UTIs, as many infections seem to respond better to that than trimethoprim. However, some people aren’t able to take nitrofurantoin, or find that their infection doesn’t respond to it, and in this case, they will be offered trimethoprim.
You can buy trimethoprim from Doctor4U after completing a consultation form for cystitis. Once you’ve filled out all questions, it will be sent to our doctors for review.
