Hi Everyone, Does anyone have anything special to report re cough meds and their possible interaction with PD meds? I'm particularly interested in Novahistex (DM) but would like to know if there are *any* cough meds not compatible with PD meds. The 'DM' addition to these meds may or may not be important. Many thanks in advance for any and all advice. H.Spence ([log in to unmask]
