Many experts consider it safe to use acne medicine that uses erythromycin (a prescription antibiotic cream) or azelaic acid, but you will need to talk to your doctor first.
Using benzoyl peroxide, which is available over the counter, might manage acne. Some doctors consider it safe; others do not. Few studies have looked into its safety, so double check with your doctor before using it.
When all else fails, talk to your doctor before using over-the-counter products. Medication should be a last resort, because even topical medicines (applied to your skin) can enter your bloodstream and cross the placenta to your unborn child.
