Betalac AC is used to treat infections caused by susceptible bacteria, including: lower respiratory tract infections (such as pneumonia) caused by H. influenzae and M. catarrhalis; acute bacterial otitis media (middle ear infection); sinusitis; skin and skin structure infections (e.g., caused by S. aureus or E. coli). It is for adults and pediatric patients.

Dosing depends on age and weight. For adults and children over 40 kg, the typical dose is 500–875 mg every 12 hours or 250–500 mg every 8 hours (based on the amoxicillin part). For children 12 weeks and older, the dose is 25–45 mg/kg/day divided every 12 hours or 20–40 mg/kg/day divided every 8 hours. For neonates under 12 weeks, the dose is 30 mg/kg/day divided every 12 hours. Always follow a doctor’s prescription exactly.

Important cautions
Do not use Betalac AC if you have had a serious allergic reaction to amoxicillin, clavulanate, or other beta-lactam antibiotics (penicillins, cephalosporins).
