I TAKE 5MG OF LEVETHOROZINE (SP) FOR UNDER ACTIVE THYROID, I DO THIS FIRST THING UPON GETTING UP IN MORNING, THEN WITHING 1/2 TO AN HOUR LATER I TAKE 10 MG OF GLIPISIDE ER. I ALSO HAVE MOBIC FOR RA CONDITIONS IN MY THUMBS. HOW FAR APART SHOULD I BE TAKING THESE MEDS FROM EACH OTHER? I AM TO TAKE VITAMIN D 3 BECAUSE I AM DEFICIENT AS WELL AS B12 - WORRIED ABOUT DRUG INTERACTION. I MONITOR MY BLOOD SUGAR 2 TIMES A DAY - MORE IF I FEEL IT IS NECESSARY, SINCERELY MELONIE
