i was wondering if anyone could tell me which drug is most comonly taken in the early stages of PD. My mothers friend takes 'EFEXOR - XR' (VENLAFAXIN). However, I have been reading that 'LEVODOPA' is common. Can anyone tell me the difference betweeen these two? Maybe a little about LEVODOPA? is the drug she is taking an anticholinergic drug? Help me please????? Thankyou Kind Regards Emma
