Zaptra12.5 (paroxitine+clonazepam)  3. Brain MRI, [ he found very small spot on MRI  ( hypodense in left besal ganglia)] So he also suggest clopitab 75(clopidogral) .  on that time my anxiety level was too high and  I was thinking I have serious issue in my brain, I can't do anything in my life ect. Then after 90days he took off clopitab, but continue zaptra and betacap for my anxiety and panic ocd,  But the problem is those medicines still continue from last 8 year just betacap reduce to 20mg, zaptra LS is continue clonazepam reduce now from .50, to .25. now from few year i have some memory problem,  confussion, lack of concentrations .so  how can I get rid off from those medicines? doctor please suggest something or help me.
