Althrocin Drops may be prescribed for a 4‑month‑old baby only if a paediatrician confirms a bacterial infection. The dosage is individualised and depends on factors such as the severity of the infection, the baby’s age, weight, and overall health. A paediatrician will assess these before deciding the appropriate dose and duration. Antibiotics should never be used without medical supervision, as inappropriate use can cause side effects, disturb the baby’s gut microbiota, contribute to antibiotic resistance, and result in ineffective treatment. Professional guidance is essential to ensure both safety and proper care.
