I think the expiration date on medications is that it starts to lose its strength. I think.

My daughter had me get something that you mix in water to help stifle a cold. I think it worked. I was just showing symptoms. It's called Emergen-C.

I've taken Alka-Seltzer for colds that helped, also Dayquil. I hope you are feeling better. Nothing worse than a nagging cold.
