I think the expirstion date signals when you can expect a loss of potency to begin. I would think that at 7 months past expiration there is a minimal loss, not enough to chuck the meds. Why don't you try one and see how much relief it provides. If it is half as potent, double up the dosage. Just a guess on my part but I think you are probably going to have better than 50% potency and maybe close to 100%.
