I have Parkinsons and anxiety.  Am currently on effexor er 37.5 and want to stop due to constipation side effect.  I have tried multiple anti-depressants with little success.  I believe the anxiety (jitters) is a result of my parkinsons meds.  It only occurs after I take my medicine.  Do I have to wean off the effexor?  Ive been on it for 2 weeks.  Can you recommend a antidepressant for med induced anxiety?  I need the meds unfortunately for control of my parkinsons (14 years now)
Hello, Welcome to Chat Doctor In more than 50% of patients of Parkinson's disease psychiatric symptoms like depression and anxiety are seen. The symptoms are seen due to disease itself and probably not due to medicines. Venlafaxine is a good Chat Doctor.  As per my opinion it should be tapered gradually over 2-4 weeks. There are other medicines specially SSRIs as Sertraline that can be used in anxiety and depression associated with Parkinson's patient. You can consult your psychiatrist to get prescription for the anxiety symptoms. Thanks
