Since she is only three and a half months old and has been coughing for over a week, it is very important not to start any new medications without a doctor's guidance. While the chlorpheniramine and phenylephrine in Sinarest AF helped her runny nose, and ambroxol in Mucolite was used, persistent coughing in young infants needs a physical exam. Please have her evaluated by a pediatrician. They can listen to her chest to ensure her lungs are clear and recommend the safest treatment. In the meantime, keeping her well-hydrated and using saline nasal drops can help her feel more comfortable.

Sinarest AF Drops contain Chlorpheniramine and Phenylephrine. This medicine should not be given to a 5-month-old baby unless specifically prescribed by a paediatrician. In infants, cold and cough medicines can carry risks, and the correct treatment depends on the baby’s age, weight, symptoms, and overall health. Please consult a paediatrician before giving this medicine to ensure safety and proper care.

Sinarest AF syrup or drops can be given to a 3-month-old only under a paediatrician's guidance, as the dose and safety need careful supervision. Always consult the doctor before giving any cold medicine.
