My son is 7.5 months old, he is suffering from severe cough and cold, doctor prescribed amoxicillin and potassium clavulanate oral suspension IP antibiotic, to give 2.5 ml daily twice, today is 5th day, still cough has been not reduced, while coughing he will cry and will act like getting vomit, he cries whole day and refuses to eat r drink, and there is loose motion also. My question is, how many days it takes to get cure? Will my son will be alright from this medicine only? Shall I change the doctor? Plsssss pour your suggestions.
