Hi I have had acne for years now and I went to the doctor who prescribed Oxytetracyline which is a mild antibiotic. The instructions do say that it is designed to treat infections that are caused by bacteria. I went to a health specialist who checked me out my blood, urine, salt levels and all the rest, he said that it was a digestive problem that i have yet a am struggling to find something to help it only Oxytetracyline which the doctor gives me everytime i go. I would like to stop taking them but when i do it comes back on my face and chest as as many of you know is not just plain ugly but sore.
