I have the Robiutssin extended release 12 hour cough and it says it has DXM polistrex equal to 30mg DXM hbr per 5ml. With it being the extended release in mind, would I need to take more to control tolerance or is the usual ~30-90mg still the right dose? And also would I need to take it earlier than the usual 30-45min before dosing?
