How long does Diclofenac (Voltaren) last in the body?
It takes approximately 5.5 half lives before the drug is completely out of your system. As the half life is 2 hours it would take about 11 hours (2 hours x 5.5 half lives) before diclofenac would have been out of your system,so theoretically you would have been diclofenac free by 4.30 am. So it was safe for you to take Zoloft at 9.30 am.
