A member asked:

I drank one packet of theraflu nighttime severe cough & cold about 4 hrs ago, my cough will not stop. can i take 2.5ml of promethazine-codeine syrup?

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.
