Erythromycin or tetracycline ointment, the choice of drug

With infectious eye lesions, both drugs can be used, since they are equally effective. But if long-term treatment is required, then an agent with tetracycline should be chosen, since it to a lesser extent causes resistance of pathogenic microorganisms to an antibiotic.

Tetracycline and erythromycin penetrate the placenta and breast milk, so they must be used very carefully during pregnancy and breastfeeding.

If a medication is needed to treat skin lesions, then only 3% tetracycline ointment is suitable. It should be used to eliminate acne and rosacea, but for these diseases it is better to use other means aimed at combating acne.

Both methods are used in pediatrics, they are prescribed even to infants. For the treatment of ophthalmia in newborns, it is preferable to use an ointment with erythromycin.

It must be remembered that the use of drugs without first consulting a doctor is fraught with complications and the occurrence of side effects. If therapy is required for a pregnant woman or young child, then only a doctor should prescribe a medication.
