Hey. It's been awhile since I posted. I've been doing GREAT for the last year and a half now ever since I've been on caltrate. Anyways I was at my Dermatologist today for my acne checkup. I've been an an Antibiotic for almost two years now. He said that I shouldn't take the Caltrate at the same time I take the anibiotic because they can bind together and not work as well. Said take the Caltrate and hour before or after taking it.He did also have me get a blood test today because I've been on the antibiotic for so long.So what is it that the anti biotic does to my body that can be harmful? I've heard its not good to be on them for a long time.I have had a few small pimple breakouts lately because I think I've taken the calcium caltrate too soon when taking my antibiotic. No way I'm stopping Caltrate for my acne!Btw My doctor said I shouldn't drink milk that much or any other dairy product for that matter cause of the IBS. Will the caltrate make up for the lack of dairy products?
