Is Taking Folic Acid Safe After A Stroke?

I HAD A MASSIVE STROKE IN MY CERREBELLUM IN DECEMBER OF THIS YEAR SINCE THEN I HAVE HAD 3 TIAS IN WHICH I LOSS USE OF MY LEFT LEG HOWEVER IT HAS ALWAYS RESOLVED ITSELF BUT SETS BACK MY PROGRESSS. THEY WANT ME TO TAKE FOLIC ACID AND BVITAMINS IS ADDITION TO COMADIN WHICH WAS JUST CHANGED FROMPLAVIX AFTER THE 3RD TIA INR FRIDAY WAS 2.8 AND I ALSO TAKE MECLAZINE AND LISINAPRIL CHOLESTEROL PILLS AND PEPCID VALIUM AND ZOOLOFT SINCE THE STROKE DUE TO ANXIETY....SCARY THIS ALL HAPPENING AT 61 WITH NO PREVIOUS HX OR ANY ABUSE MY MAJOR CONCERN TODAY IS THE FOLIC ACID AS I HAVE READ BAD SIDE EFFECTS THANK YOU
