Cough : Both contain an antihistamine. Theraflu doesn't contain an effective cough suppressant but promethazine-codeine does. If you have a dry irritating and persistent cough, I would take this suppressant syrup and I don't think it will be a problem to take it again according to the dosage instructions.
