FAQ
Fosfomycin is a prescription-only antibiotic when obtained from local pharmacies in the United Kingdom. Our store policy allows you to order it without a prescription and have it sent by mail.
Do not extend treatment or take additional sachets without clinical advice. A 3 g sachet is commonly used as a single dose for uncomplicated cystitis; persistent or worsening symptoms may need reassessment rather than more of the same antibiotic.
Do not keep leftover sachets for a future urinary infection or give them to anyone else. Take unused medicine to a pharmacy for safe disposal where possible, and keep sachets dry and out of the reach of children until then.
Yes. Fosfomycin granules for oral solution are supplied in sachets and can normally travel by post when packed to protect them from damage and moisture. On arrival, check that the sachets are intact and dry, and store them at 25°C; temporary excursions from 15°C to 30°C are permitted.
Fosfomycin is an antibiotic used principally for acute uncomplicated lower urinary tract infection, also called acute cystitis. The 3 g oral sachet regimen is established for adult women and female adolescents aged 12 years and over when it is appropriate for the infection.
Dissolve the entire contents of one sachet in a glass of water and drink the solution straight away; do not swallow the dry granules. For uncomplicated cystitis, the usual regimen is one 3 g sachet taken on an empty stomach, ideally at bedtime after emptying the bladder. Follow the regimen given for your particular condition.

Fosfomycin 3 g Sachet (Granules for Oral Solution)
Fosfomycin (fosfomycin trometamol) is a single-dose antibiotic taken by mouth and supplied as granules for oral solution. In UK prescribing information, it is used for uncomplicated lower urinary tract infection (acute cystitis) in women caused by susceptible strains of Escherichia coli and Enterococcus faecalis. It is not indicated for pyelonephritis (kidney infection) or perinephric abscess, so clinicians and patients should check the relevant UK product information for the licensed indication and prescribing details.
Dosage and Directions
Adults (women aged 18 and over): one sachet (3 g) taken as a single dose. It can be taken with or without food.
How to take: Pour the entire contents of the sachet into 3 to 4 ounces of water (1/2 cup) and stir until dissolved. Do not use hot water. Take it immediately after dissolving. Do not take it dry.
Your symptoms should improve within about 2 to 3 days. If they do not, contact your healthcare professional.
Precautions
- Do not use more than one single dose to treat one episode of acute cystitis. Repeated daily doses did not improve outcomes and increased side effects.
- Antibiotic-associated diarrhoea: diarrhoea can occur with antibiotics. Get medical advice straight away if you develop watery or bloody stools, with or without stomach cramps and fever, even up to 2 months after taking the dose.
- Pregnancy: use during pregnancy only if clearly needed.
- Breastfeeding: it is not known whether fosfomycin tromethamine passes into human milk; discuss feeding options with your UK healthcare professional.
- Paediatrics: safety and effectiveness in children 12 years and under have not been established.
Contraindications
Do not use in patients with known hypersensitivity to fosfomycin.
Drug Interactions
- Metoclopramide (and other medicines that increase gastrointestinal motility) may lower serum concentrations and urinary excretion of fosfomycin.
- Cimetidine does not affect fosfomycin pharmacokinetics when given at the same time.
Possible Side Effects
In clinical studies, the most common drug-related side effects (>1%) were diarrhoea, vaginitis, nausea, headache, dizziness, asthenia, and dyspepsia. Other events reported in clinical trials included rhinitis, back pain, dysmenorrhoea, pharyngitis, abdominal pain, rash, and temporary changes in lab results.
Rare serious events have been reported after marketing, mostly outside the United States, including angioedema, aplastic anaemia, asthma exacerbation, cholestatic jaundice, hepatic necrosis, and toxic megacolon. During post-marketing surveillance, anaphylaxis and hearing loss have also occurred.
Missed Dose
This product is taken as a single dose. If you forget to take it, take it as soon as you remember on the same day. Do not take an extra sachet to make up for a missed dose; contact your prescriber in the United Kingdom for advice.
Overdose
Events observed in patients who have taken too much fosfomycin include vestibular loss, impaired hearing, metallic taste, and a general decline in taste perception. In the event of overdose, treatment should be symptomatic and supportive. Seek urgent medical help if an overdose is suspected.
Storage
Store at 25°C (77°F); excursions permitted to 15-30°C (59-86°F). Keep out of the reach of children.

Customer questions
I'm in Newry, Northern Ireland. Can I confirm that fosfomycin can be delivered to my address before paying?
Please enter your Newry postcode at checkout before payment. The delivery options shown there confirm whether this product can be sent to your address.
I have bought a fosfomycin sachet for cystitis and have just found out that I'm pregnant. Should I still take it?
Do not make a stop-or-start decision on your own. Fosfomycin may be used in pregnancy when a prescriber considers it clinically necessary, but the infection and treatment choice should be reviewed promptly by a clinician.

This fosfomycin granules for oral solution worked well for me, though delivery was two or three days quicker back when I lived in London, not always the case from Leeds.
