Adverse reactions may occur with any medication. Common side effects are usually mild and self‑limiting.

Common Side Effects: - Nausea: mild to moderate stomach upset. - Diarrhoea: loose stools occurring within a few hours of dosing. - Abdominal pain: cramping or discomfort in the lower abdomen. - Headache: transient mild headache. - Vomiting: occasional emesis after ingestion. - Flatulence: increased gas production.

Serious or Rare Side Effects: - Allergic reactions: rash, pruritus, or anaphylaxis requiring immediate medical attention. - Clostridioides difficile infection: severe colitis presenting with watery diarrhoea. - Severe liver injury: jaundice, elevated transaminases, or hepatitis. - Renal impairment: worsening kidney function in susceptible individuals. - Hematologic abnormalities: rare cases of neutropenia or thrombocytopenia.

Before prescribing Monuril, clinicians should consider several safety aspects.

- Renal function assessment: adjust use in patients with severe renal impairment. - Pregnancy caution: safety category unknown; weigh benefits against potential risks. - Breastfeeding advice: consider potential excretion in milk and infant exposure. - Hypersensitivity screening: avoid in individuals with known fosfomycin allergy. - Concomitant medications: monitor for interactions that may affect efficacy or safety. - Store below 25°C: keep in the original pack, protect from moisture.

Fosfomycin may interact with other medicines, altering its absorption or effect.

Major Interactions (Avoid): - Antacids containing magnesium or aluminum: reduce fosfomycin absorption. - Metoclopramide: delays gastric emptying, decreasing bioavailability. - Other antibacterial agents: may interfere with synergistic activity.

Moderate Interactions (Monitor Closely): - Warfarin: possible increase in INR, requiring coagulation monitoring. - Oral contraceptives: potential reduction in contraceptive efficacy; advise additional protection. - Diabetes medications: may affect glycaemic control, necessitating closer monitoring.
