If it's an antibiotic. I recommend get off of it asap. Even though it will clean you out as far as acne goes and fight it off, it will also lower your immune system badly (this is why it is a doctor's last resort and they don't like to give antibiotics to people who are sick unless it is absolutely necessary such as strep or something)
I took an antibiotic for years for my acne and even though it took care of it, i now have an extremely weak immune system and cannot fight things off as well as I should be able to. I also suffer from a lot of allergies due to this.
