acne
"I was on this antibiotic when I was in my early 20's and it worked really well. My skin cleared within a week. Although I started to get joint pain and had to stop taking it.

A couple of years later I went back on it and I didn't have any side effects but the doctor asked me to stop taking it because of the longer term side effects.

My skin has always been up and down but 3 years later it started to concern me so a dermatologist prescribed me them again a couple of weeks

Only this time the side effects were so much worse. I was vomiting and had severe chest pains, making it hard for me to breathe. I couldn't belive that the antibiotic that had worked so well for me was causing this amount of pain. So please, where you can, avoid taking them"
