Im taking this medicine against acne.
Wants to know a few things.
1. Except for redness of skin, what other side effects are there?
2. Is it okay for prolong use?
3. Is it an anti biotic?

thanks

2) yes, although your dose may be decreased once you are using it for acne prevention rather than to get rid of already present acne.
3) no
