Print Friendly, PDF & Email

Generic Name: fosfomycin trometamol
Product Name: Monurol

Indication: What Monurol is used for

Monurol is only used to treat uncomplicated infections of the bladder in females.

Ask your doctor if you have any questions about why this medicine has been prescribed for you. Your doctor may have prescribed it for another reason.

Monurol is not addictive.

It is available only with a doctor’s prescription.

Action: How Monurol works

Monurol contains the active ingredient fosfomycin trometamol and it belongs to a group of medicines called antibiotics. It works by killing bacteria which can cause infections.

Fosfomycin inhibits the first stage of bacterial wall synthesis. It inhibits the phosphoenolpyruvate transferase enzyme, thereby irreversibly blocking the condensation of uridine diphosphate-N-acetylglucosamine with p-enolpyruvate.

There has been very limited fosfomycin susceptibility testing performed in Australia to date. Recommendations are based on studies performed overseas.

Bacterial species commonly susceptible to fosfomycin using European Committee on Antimicrobial Susceptibility Testing (EUCAST) or Clinical and Laboratory Standard Institute (CLSI) susceptibility testing guidelines:

  • Escherichia coli;
  • Proteus spp.;
  • Klebsiella spp.;
  • Citrobacter spp.;
  • Enterococcus faecalis.

Bacterial species variably susceptible or resistant to fosfomycin using EUCAST or CLSI susceptibility testing guidelines:

  • Enterobacter spp.;
  • Serratia marcescens;
  • Providencia spp.

Bacterial species frequently resistant to fosfomycin using EUCAST or CLSI susceptibility testing guidelines:

  • Morganella morganii.

Oral fosfomycin is not recommended in the treatment of the following bacterial species which do not have EUCAST or CLSI susceptibility testing guidelines:

  • Staphylococcus saphrophyticus;
  • Pseudomonas aeruginosa;
  • Enterococcus faecium;
  • Staphylococcus aureus;
  • Acinetobacter spp.;
  • Stenotrophomonas maltophilia;
  • Bacteroides spp.;
  • Other anaerobic bacteria.

Monurol contains 5.631 g of fosfomycin trometamol as the active ingredient, equivalent to 3 g of fosfomycin.

It also contains the inactive ingredients tangerine flavour, orange juice flavour, saccharin, and sucrose (Monurol contains 2.213 g of sucrose).

This medicine does not contain lactose, gluten, tartrazine or any other azo dyes.

Dose advice: How to use Monurol

Before you take Monurol

When you must not take it

Do not take Monurol if you:

  • Are allergic to fosfomycin trometamol or any of the other ingredients listed here;
  • Have severe kidney problems (creatinine clearance below 10 ml/min);
  • Are undergoing haemodialysis.

Some of the symptoms of an allergic reaction may include:

  • Shortness of breath;
  • Wheezing or difficulty breathing;
  • Swelling of the face, lips, tongue or other parts of the body;
  • Rash, itching or hives on the skin.

Do not give this medicine to a child under the age of 12 years. Safety and effectiveness in children younger than 12 years have not been established.

Do not take this medicine after the expiry date printed on the pack or if the packaging is torn or shows signs of tampering. If it has expired or is damaged, return it to your pharmacist for disposal.

If you are not sure whether you should start taking this medicine, talk to your doctor.

Before you start to take it

Tell your doctor if you have allergies to any other medicines, foods, preservatives or dyes.

Tell your doctor if you have or have had any of the following medical conditions:

  • An intolerance to some sugars;
  • Previously had diarrhoea after taking any antibiotics;
  • Kidney problems, but your creatinine clearance is above 10 ml/min.

Tell your doctor if you are pregnant or plan to become pregnant or are breastfeeding. Your doctor can discuss with you the risks and benefits involved. If you are pregnant, the active ingredient in Monurol can cross the placenta and Monurol can pass into the foetus. There is a possibility that your baby may be affected. The active ingredient in Monurol passes into breast milk and there is a possibility that your baby may be affected.

If you have not told your doctor about any of the above, tell them before you start taking Monurol.

Taking other medicines

Tell your doctor or pharmacist if you are taking any other medicines, including any that you get without a prescription from your pharmacy, supermarket or health food shop.

Some medicines and Monurol may interfere with each other. These include:

  • Metoclopramide or other drugs that increase the movement of food through the stomach and intestines, because they may reduce the uptake of fosfomycin trometamol by your body;
  • Anticoagulants, as their ability to prevent your blood from clotting, might be altered by fosfomycin trometamol and other antibiotics.

These medicines may be affected by Monurol or may affect how well it works. You may need different amounts of your medicines, or you may need to take different medicines.

Your doctor and pharmacist have more information on medicines to be careful with or avoid while taking this medicine.
