How to take erythromycin + tretinoin
Use only on the skin as directed by the prescriber.
Press the screw-cap top onto the foam pad until it clicks, invert the bottle to wet the pad, then wipe over the affected skin.
Avoid excessive application, skin folds and the angles of the nose.
Keep away from the eyes and eyelids. Rinse thoroughly with water after accidental contact.
Wash the solution from your fingers after application.
Do not apply before swimming.
Keep away from cigarettes and flames until completely dry because the solution is flammable.
