My 3 old had persistent cough so i got her checked . Doctor prescribed telekast L kid for 30 days (one tablet at night) , and levolin 3.5 mg twice a day . Now 3 year old has dry mouth and constipation after 15 days. Also if one dose is missed then her cough worsens, should i continue the treatment and then go to doctor again or should i tell him my concerns now only , as my baby’s cough is only suppressing and not clearing.
