Mechanism of action

* Because of the potential for chemical conversion to methamphetamine, pseudoephedrine & ephedrine are restricted substances. As of Sept 30, 2006, pseudoephedrine & ephedrine will be behind the counter. Only 3.6 g/day & 9 g/month will be dispensed. This works out to be 120 tablets of pseudoephedrine 30 mg per day, or 300 tabs/month.[5]
