Pregnancy Risk Factor
Adverse events were not observed in animal reproduction studies. Erythromycin has been shown to cross the placenta following oral dosing. Refer to the Erythromycin (Systemic) monograph for details. The amount of erythromycin available systemically following ophthalmic application is not known. Systemic absorption would be required in order for erythromycin to cross the placenta and reach the fetus.
• Discuss specific use of drug and side effects with patient as it relates to treatment. (HCAHPS: During this hospital stay, were you given any medicine that you had not taken before? Before giving you any new medicine, how often did hospital staff tell you what the medicine was for? How often did hospital staff describe possible side effects in a way you could understand?)
• Patient may experience eye redness. Have patient report immediately to prescriber vision changes, eye pain, or severe eye irritation (HCAHPS).
• Educate patient about signs of a significant reaction (eg, wheezing; chest tightness; fever; itching; bad cough; blue skin color; seizures; or swelling of face, lips, tongue, or throat). Note: This is not a comprehensive list of all side effects. Patient should consult prescriber for additional questions.
