<<Disclaimer: Verify this information before applying it to your situation.>> I experienced severe bloating, nausea, and light-headedness within an hour of swallowing a tetracycline capsule this morning (for a skin condition). Suspecting gluten, I called up the pharmacist who found lactose in the manufacturer's list of ingredients. He says there is no alternative for me, other than taking lactaid tablets. As I've already mentioned in a previous posting, lactaid tablets don't work for me. Has anyone else had this problem before? How did you deal with it? I've left a message for my physician, but I'm not hopeful. She doesn't seem to know much about cd. I'd really appreciate your help. Meantime I am discontinuing the antibiotic. Thanks, Shashi
