Interaction with other drugs

Fosfomycin tromethamine can interact with other drugs, potentially affecting their effectiveness or causing adverse effects. Here are some known drug interactions:

  • Probenecid: Probenecid is a medication often used to treat gout. It can reduce the elimination of fosfomycin from the body, leading to increased levels of fosfomycin in the bloodstream. This can enhance the effectiveness of Monurol.
  • Drugs That Affect the Kidneys: Since Monurol is primarily excreted by the kidneys, drugs that affect kidney function may influence the elimination of fosfomycin. This can include medications that affect renal function or other antibiotics that are excreted by the kidneys.
  • Metoclopramide: Metoclopramide is a medication used to treat gastrointestinal issues. It can potentially increase the absorption of fosfomycin, leading to higher blood levels. If you are taking metoclopramide.
  • Anticoagulants (Blood Thinners): Fosfomycin may have a potential interaction with certain anticoagulant medications. If you are taking blood thinners, your healthcare provider should monitor your blood clotting parameters carefully.
  • Other Antibiotics: Concurrent use of fosfomycin with other antibiotics may lead to increased antibiotic resistance and reduced effectiveness.
