Most of cough suppressent and antibiotics in cough and cold is not desirable due to untoward side effects remember largest number if cases of cough and cold with without fever are viral and thus subside in less than a week
at most you can try home made remedy like karha honey garlic.
However if cough and fever is persistent beyond 7 days please consult your doctor. 3 phials of tixylix and antibiotics is not at all justified.
