Monuril (Fosfomycin Trometamol)

Fosfomycin Trometamol, the active ingredient in Monuril, is a fosfomycin (phosphonic acid derivative antibacterial) presented as an oral tablet for oral use. It treats acute uncomplicated urinary tract infection, primarily in adult women, by eradicating susceptible uropathogens and providing symptomatic relief with a single-dose regimen.

Monuril, a fosfomycin antibacterial, is indicated for infections of the urinary tract.

Acute uncomplicated urinary tract infection (female): provides bacterial eradication and rapid symptom relief. Acute uncomplicated urinary tract infection (male): offers effective treatment when indicated, targeting common uropathogens. Recurrent uncomplicated urinary tract infection (prophylaxis): may be used as a single-dose therapy under medical supervision to reduce recurrence.

Fosfomycin Trometamol may cause a range of adverse reactions, which are categorized by frequency and severity.

Common Side Effects: - Nausea - Diarrhea - Headache

Serious or Rare Side Effects: - Anaphylactic reaction - Stevens‑Johnson syndrome or toxic epidermal necrolysis - Clostridioides difficile‑associated colitis

When prescribing Monuril, clinicians should consider several precautionary measures to ensure safe use.

Assess renal function: adjust use in patients with severe renal impairment. Verify hypersensitivity: avoid in individuals with known allergy to fosfomycin or its excipients. Evaluate pregnancy status: use only if potential benefit justifies potential risk. Monitor gastrointestinal tolerance: counsel patients on possible nausea or diarrhea. Review concomitant medications: consider possible interactions that may affect efficacy. Store at ambient temperature: keep in original packaging, protect from moisture and heat.

Fosfomycin Trometamol can interact with other medicines; some combinations should be avoided while others require monitoring.

Major Interactions (Avoid): - Antacids containing aluminum or magnesium: may markedly reduce fosfomycin absorption. - Probenecid: can increase systemic exposure and risk of toxicity. - Warfarin: may potentiate anticoagulant effect and raise INR.

Moderate Interactions (Monitor Closely): - Oral contraceptives: possible reduction in hormonal efficacy; advise backup method. - Diabetes medications: monitor blood glucose as fosfomycin may affect glycemic control. - Other renally excreted drugs: adjust dosing if renal function is compromised.
