Please do not give any alternative medicine or change dosages without consulting your paediatrician. Moxclav is a potent antibiotic, and Ascoril LS is a bronchodilator/expectorant; if your 7-month-old is not improving, the cause might be viral (which antibiotics cannot treat) or require a different treatment. Self-medicating infants is highly risky. Please have a paediatrician re-evaluate your baby immediately to listen to their chest and check their breathing. In the meantime, ensure your baby is well-hydrated with breast milk or formula, and you may use saline nasal drops with a bulb syringe to help clear congestion safely.
