Full prescribing information FDA SPL
🎯 Indications and Usage ▾
INDICATIONS AND USAGE: For the treatment of superficial ocular infections involving the conjunctiva and/or cornea caused by organisms susceptible to erythromycin. For prophylaxis of ophthalmia neonatorum due to N. gonorrhoeae or C. trachomatis . The effectiveness of erythromycin in the prevention of ophthalmia caused by penicillinase-producing N.gonorrhoeae is not established.
For infants born to mothers with clinically apparent gonorrhea, intravenous or intramuscular injections of aqueous crystalline penicillin G should be given; a single dose of 50,000 units for term infants or 20,000 units for infants of low birth weight. Topical prophylaxis alone is inadequate for these infants.
⏱️ Dosage and Administration ▾
DOSAGE AND ADMINISTRATION: In the treatment of superficial ocular infections, a ribbon approximately 1 cm in length of Erythromycin Opthalmic Ointment should be applied directly to the infected structure up to 6 times daily, depending on the severity of the infection. For prophylaxis of neonatal gonococcal or chlamydial conjunctivitis, a ribbon of ointment approximately 1 cm in length should be instilled into each lower conjunctival sac. The ointment should not be flushed from the eye following instillation.
A new tube should be used for each infant.
⛔ Contraindications ▾
CONTRAINDICATIONS: This drug is contraindicated in patients with a history of hypersensitivity to erythromycin.
🤒 Adverse Reactions ▾
ADVERSE REACTIONS: The most frequently reported adverse reactions are minor ocular irritations, redness, and hypersensitivity reactions.
🤰 Pregnancy ▾
Pregnancy: Teratogenic Effects: Pregnancy Category B. Reproduction studies have been performed in rats, mice, and rabbits using erythromycin and its various salts and esters, at doses that were several multiples of the usual human dose. No evidence of harm to the fetus that appeared related to erythromycin was reported in these studies.
There are, however, no adequate and well controlled studies in pregnant women. Because animal reproductive studies are not always predictive of human response, the erythromycins should be used during pregnancy only if clearly needed.
🧒 Pediatric Use ▾
Pediatric Use - See INDICATIONS AND USAGE and DOSAGE AND ADMINISTRATION .
🧓 Geriatric Use ▾
Geriatric Use: No overall differences in safety or effectiveness have been observed between elderly and younger patients.
🧬 Clinical Pharmacology ▾
CLINICAL PHARMACOLOGY: Microbiology: Erythromycin inhibits protein synthesis without affecting nucleic acid synthesis. Erythromycin is usually active against the following organisms in vitro and in clinical infections: Streptococcus pyogenes (group A β-hemolytic) Alpha-hemolytic streptococci (viridans group) Staphylococcus aureus , including penicillinase-producing strains (methicillin-resistant staphylococci are uniformly resistant to erythromycin) Streptococcus pneumoniae Mycoplasma pneumoniae (Eaton Agent, PPLO) Haemophilus influenzae (not all strains of this organism are susceptible at the erythromycin concentrations ordinarily achieved) Treponema pallidum Corynebacterium diphtheriae Neisseria gonorrhoeae Chlamydia trachomatis
