Product information: Fosfomycin for UTI

What is fosfomycin?

Fosfomycin is a prescription antibiotic used to treat uncomplicated urinary tract infections (UTIs), such as cystitis, in women. It comes as granules in a sachet that you dissolve in water and drink as a single dose. It works by stopping bacteria from building their cell walls, which kills them.

Fosfomycin is one of the antibiotics recommended in UK guidance when nitrofurantoin is not suitable. It is not suitable for kidney infections. Your prescriber will check your medical history to make sure it is safe for you.

Who can get fosfomycin for a UTI?

Fosfomycin may be suitable if you:

  • Are a woman aged 18 or over and not pregnant
  • Have symptoms such as needing to pee more often or urgently, pain or burning when you pee, or cloudy urine
  • Do not have a high temperature, pain in your back or side, or feel generally unwell

Nitrofurantoin is usually the first choice for UTIs in women. Our prescribers may recommend fosfomycin if nitrofurantoin is not suitable for you, for example because of reduced kidney function, an allergy or a recent UTI that did not clear.

During your online consultation, we’ll ask you about:

  • Your symptoms and how long you have had them
  • Any symptoms that could suggest a kidney infection, such as fever or back pain
  • Any medical conditions you have, especially kidney problems
  • Past or present allergies to medicines
  • Any medication or treatments you’re currently having
  • If you’re pregnant or breastfeeding

This will help your prescriber find a treatment that’s safe and effective for you. Antibiotics are only prescribed when clinically appropriate to reduce unnecessary antibiotic use and antimicrobial resistance.

Side Effects

Like any treatment, fosfomycin can cause some side effects, although not everybody gets them. Most are mild and pass with time, such as:

  • Diarrhoea
  • Feeling sick (nausea) or indigestion
  • Headache or dizziness
  • Vaginal itching or thrush

We’ll explain what to look out for and ways to manage any side effects.

Rarely, fosfomycin can cause serious side effects. Get urgent medical advice if you develop severe diarrhoea, especially if it contains blood or mucus.

Please call 999 or go straight to A&E if you have:

  • Difficulty breathing or swallowing
  • Swelling of the face, lips, tongue or throat
  • A severe skin rash with blistering, peeling or sores

If you notice any changes not listed above or if any side effects become difficult to manage, please speak to your doctor or pharmacist for further guidance. You can also report it through the Yellow Card Scheme to help others take their medication safely.

Yes. Fosfomycin is one of the antibiotics recommended by NICE for uncomplicated UTIs in women who are not pregnant, when nitrofurantoin is not suitable. It works against E. coli, the bacteria that cause most UTIs, and because it’s a single dose, there’s no course to remember.

Complete our online consultation for a clinical assessment by one of our experienced prescribers to find out whether you’re eligible for a prescription to buy fosfomycin 3g sachets online.

Monuril is a brand name for fosfomycin 3g granules. They contain the same active ingredient and work in the same way.

Yes. A single 3g dose of fosfomycin stays at high levels in your urine for 1 to 2 days, which is long enough to treat most uncomplicated UTIs in women. Your symptoms may take 2 to 3 days to settle after the dose.

You cannot buy fosfomycin over the counter at a pharmacy as it is a prescription-only medication. This means you must have a prescription from a licensed prescriber to buy fosfomycin for a UTI.

If you think you have a UTI, you can fill out our simple online questionnaire to start your consultation with one of our UK-registered prescribers. Then, if prescribed, you can buy fosfomycin 3g sachets through our online pharmacy with fast UK delivery.

You can order fosfomycin 3g sachets through an online pharmacy after a clinical assessment with a registered prescriber. A prescriber will only prescribe fosfomycin if it’s clinically appropriate for you and your situation.

Do not buy antibiotics from pharmacies or websites that do not require a consultation with a medical professional.

At My Chemist Plus, you can have a free consultation with a UK-registered, experienced prescriber for fosfomycin. If prescribed, you can order fosfomycin online with fast UK-wide delivery. Fill out a quick health questionnaire to get started.

Not always. Some mild UTIs get better on their own within a few days. Antibiotics are usually recommended when your symptoms are bothersome, aren’t improving, or you have several typical symptoms together. Our prescribers use these clinical criteria during your consultation to decide whether antibiotics are likely to help.

Always follow your prescriber’s instructions. Fosfomycin is a single dose, so you only take it once.

  • Take it on an empty stomach, at least 2 to 3 hours before or after eating. Bedtime, after emptying your bladder, is often best.
  • Empty the contents of the sachet into a glass of water, stir and drink it straight away.
  • Do not take it with hot water.

If you are sick (vomit) within a few hours of taking fosfomycin, contact us or a pharmacist for advice, as the dose may not have been absorbed.

For women with an uncomplicated UTI, the dose is a single 3g sachet, taken once.

Many women start to feel better within 1 to 3 days. If your symptoms do not start to improve within 3 days, or they get worse, seek medical advice. Do not take another antibiotic without a new assessment.

Our service does not supply fosfomycin during pregnancy. UTIs in pregnancy need a urine test and a different choice of antibiotic, so please speak to your GP or midwife.

If you’re breastfeeding, let your prescriber know during your consultation so they can give you the right guidance.

Alcohol does not interact with fosfomycin. But, it’s a good idea to avoid alcohol while you have a UTI, as it can irritate your bladder and make symptoms worse.

Fosfomycin can make some people feel dizzy. If this happens, do not drive or operate machinery until you feel better.

Fosfomycin does not affect the contraceptive pill directly. It also does not affect the emergency contraceptive pill. But, fosfomycin can cause vomiting or diarrhoea in some people.

If you’re vomiting or have diarrhoea for more than 24 hours, this may prevent your contraceptive pill from working. To find out what to do, read the patient information leaflet that comes with your contraceptive medication, speak to your doctor, or visit the NHS website for guidance.

Tell your prescriber about all medicines you take. In particular, mention metoclopramide, used for sickness, as it can stop fosfomycin working as well.

Nitrofurantoin is usually the first choice for UTIs in women, with trimethoprim and pivmecillinam as other options. Your prescriber will recommend the most suitable treatment during your consultation.

Learn more about nitrofurantoin and trimethoprim for UTIs.

While you recover, drink plenty of fluids so you pee regularly, and take paracetamol or ibuprofen for pain if they’re suitable for you. Rest and avoid sex until you feel better.

To help prevent UTIs in future, wipe from front to back after using the toilet, pee as soon as possible after sex, and don’t hold in your pee when you need to go.

Seek urgent medical advice if you:

  • Have a high temperature or feel hot and shivery
  • Have pain in your lower back or side, just under your ribs
  • Feel sick, are vomiting or feel very unwell
  • Notice blood in your urine that does not go away
  • Do not start to feel better within 48 hours of starting treatment
