Before prescribing Fosfomycin, clinicians should consider patient‑specific factors and safety measures.

- Renal function: assess kidney status, as dosing may need adjustment. - Hypersensitivity: avoid in patients with known allergy to fosfomycin or related compounds. - Pregnancy: use only if the potential benefit outweighs unknown risks. - Breastfeeding: consider potential exposure to the infant through milk. - Concomitant antibiotics: evaluate for possible additive toxicity. - Store below 25°C: keep in the original pack, protect from moisture.

Fosfomycin may interact with other medicines, requiring attention to avoid reduced efficacy or increased toxicity.

Major Interactions (Avoid): - Antacids containing aluminum or magnesium: may markedly reduce fosfomycin absorption. - Calcium‑containing supplements: can bind fosfomycin and lower its bioavailability.

Moderate Interactions (Monitor Closely): - Warfarin: fosfomycin may potentiate anticoagulant effect, requiring INR monitoring. - Oral contraceptives: possible reduction in hormonal efficacy, advise backup contraception. - Diuretics: monitor electrolyte balance as fosfomycin can affect sodium handling.
