Is there something wrong with these ibuprofen pills?

Equate uses hydroxypropyl methylcellulose as a binding and release agent for their ibuprofen. If your medication was exposed to high or low temps (like leaving it in a car, near a stove or if it was compromised during shipping), the compound will crystalize and make it look metallic or glittery. It shouldn't leave any adverse effects if you took it but for safety sake, I would go ahead and toss that bottle and get a new one to ensure it works as designed. Also... try to keep it at room temp this time.

You’re not alone. I’m asking myself the same question after just purchasing Equate Ibuprofen tablets. All the tablets are coated with a glittery, metallic substance. I’m still using it with crossed fingers. I couldn’t find much help on the Internet.

That's weird. I've had equate ones and they weren't like that.
