So glad to find this forum! I totally agree that Core is a HORRIBLE generic. I broke out in red blotches on my face about 4 days after taking this brand, and it went away when I stopped the medication. My Dr prescribes Teva 30mg and I have not had problems until recently. The pharmacy couldn’t get 30mg tabs but they could get 15 mg. About 4 days into taking them my face broke out again in big red blotches. Hmmmmm. Strange. What is going on with Teva? I have read that they are struggling financially. I don’t have insurance and pay cash. Do I have to buy the brand or just not take anything? Btw I’ve had good luck with Mallinkrodt.
