Hi hi, has anyone been put on antibiotics called Dioxycline?
It's to help acne and rosacea (redness/scars that may appear on face).
What are the side effects?

Do you mean Doxycycline? If so then yes, it is used to treat acne and rosacea. More so for acne, rosacea if only it's a really bad flare. Side affects are irritation and sun sensitivity, so you're more likely to burn with prolonged exposure in the sun. Wear sunscreen and you'll be fine. Some people say they get dizzy the first couple times taking it. If you've been prescribed generic instead of name brand there's a chance of acid reflux. Other than that, it's a really effective antibiotic and works really well.
