Pharmacology
Dosage & Administration
Adults: The usual dose is 1-2 gm daily in divided doses. This may be increased up to 4 gm per day according to the severity of the infection.
Children: The usual regimen is 30-50 mg/kg/day. In severe cases the dose may be doubled.
Interaction
Theophylline: Intravenous theophylline reduces the mean steady state erythromycin concentration after oral dosing by 37%. The clearance of intravenous theophylline is reduced by 83% in subjects currently taking oral erythromycin.
Carbamazepine: Several patients receiving treatment with carbamazepine showed two or three fold increases in their steady state plasma concentrations when erythromycin was given.
Digoxin: 12% of patients receiving digoxin metabolize up to 40% of an oral dose into cardioinactive metabolites in their guts. This microbiological conversion may be inhibited by erythromycin , resulting in increases in the serum digoxin level of up to 200%.
Warfarin: There have been several case reports of prolongation of the prothrombin time and bleeding in patients on warfarin given erythromycin.
Ergotamine: A single case report describes ergotamine toxicity in a patient under treatment with ergotamine.
