NASATAPP every how many hours for 2 months old baby?

I just gave my baby nasatapp today since yun yung binigay na gamot nung pedia na nag check up sa kanya sa medical mission my baby has cough and colds hindi naman nasabi ng pedia kung ilang hours interval pero 3 times a day daw. Nag assume ako na its every 4 hours then upon reading sa box every 6 to 8 hours pala sya.. okay lang kaya na napainom ko sya ng 4 hrs palang ang interval sana po may makasagot
