Good evening house, my baby started running temperature with cough and catarrh since on the 10th of this month, I took her to general hospital, the doctor gave us drugs for malaria and respiratory tract infection, since then the cough and catarrh still persist, I took her back to the hospital on the 25th, the doctor said the cough and catarrh will go on it own, but till now my baby is still having block nose and vomit at times when she's coughing, my question now is can a 4 months plus baby use cough drug? Because a nurse in my house said I should buy cough and drugs since she has taking antibiotics since on the 14th to on the 18th.
