Drug Information
11 reviews for Fosfomycin
Fosfomycin is an antibiotic used to treat simple bladder infections (cystitis) in women. It comes as granules in a sachet that you mix into water, and usually just one dose is needed.
What is it used for?
- Simple bladder infections in adult women and teenage girls
How does it work?
Fosfomycin stops bacteria from building their outer wall, which kills them. It collects in the urine and stays there for a few days, so a single dose can clear the infection.
This information is written in simple words to help you understand this product. It does not replace advice from your doctor or pharmacist.
Read these points before you start. If any of them apply to you, talk to your doctor or pharmacist first.
- Do not take it if you have ever had an allergic reaction to this antibiotic or to a similar one.
- Antibiotics only work on infections caused by bacteria. They do not help colds, flu or most sore throats, which are caused by viruses.
- Take the whole course your doctor gives you, even if you feel better after a few days. Stopping early can let the infection come back and make germs harder to treat in the future.
- Tell your doctor if you are pregnant, trying for a baby or breastfeeding.
- Never share your antibiotics or keep leftovers for another time.
- Tell your doctor if you have kidney problems.
- It is not for kidney infections. See a doctor if you have a high fever, back pain or shivering.
- Tell your doctor or pharmacist about every other medicine, vitamin or herbal product you use.
- Keep this product out of the reach and sight of children.
Like all medicines, Fosfomycin can cause side effects, but not everybody gets them.
Common side effects
- Feeling sick (nausea) or being sick
- Diarrhoea or loose stools
- Stomach ache or indigestion
- Headache or dizziness
- Vaginal itching or discharge
These are usually mild and often get better as your body gets used to it. Tell your doctor if they bother you or do not go away.
Stop using it and get medical help straight away if you notice:
- Severe diarrhoea that is watery or has blood in it, even up to 2 months after you finish the medicine
- Signs of an allergic reaction, such as a rash, swelling of the face, lips or tongue, wheezing or trouble breathing
- A skin rash that blisters or peels, with fever and sore mouth or eyes
This is not a complete list. If you notice anything unusual, ask your doctor or pharmacist.
- Take it on an empty stomach, about 2 to 3 hours before or after a meal. Bedtime, after emptying your bladder, is a good time.
- Pour all of the granules from one sachet into half a glass of cold water.
- Stir until dissolved, then drink it straight away.
- One sachet (3 g) is usually the whole treatment. Do not take a second dose unless your doctor tells you to.
If you miss a dose: It is usually a single dose, so this does not apply. If you forget to take it, take it as soon as you remember.
If you use too much: Contact your doctor, a poison control centre or your local emergency number straight away, even if you feel fine. Take the pack with you.
How to store it: Keep it in its original pack at room temperature (below 25°C / 77°F), away from heat, damp and direct sunlight. Do not use it after the expiry date.
- QIs one dose of Fosfomycin really enough?
- A
Yes, for most simple bladder infections. The medicine stays in your urine for a few days and keeps working.
- QHow soon will I feel better after Fosfomycin?
- A
Many people feel better within 2 to 3 days. If you do not, or you feel worse, contact your doctor.
- QWhy take Fosfomycin at bedtime?
- A
Emptying your bladder first, then taking it at night, lets the medicine stay in your bladder longer while you sleep.
