you will not experience any harm. tetracycline is safe to be taking internally -- a very common and older antibiotic available in capsule form.
i'm on isotretinoin. i was at fault that i use tetracycline ointment 1% on my lip. it happened just 1 time. is it serious? . the ingredients of that tetracycline ointment - 5 g/tube: tetracyclin hydroclorid (50 mg) lanolin (247 57 mg) vaselin (4291 57 mg) beeswax (272 28 mg) parafin (138 57 mg). does tetracycline cream on skin affect just the skin or affect inside the body?
