Serum levels of 8—12 mcg/mL are possible after IV doses of 500 —1000 mg.

How is erythromycin administered?

Erythromycin is administered orally, intravenously, topically, and ophthalmically. Distribution of erythromycin is extensive following either oral or intravenous administration. Protein binding is extensive at 75% to 90%. Erythromycin is widely distributed into most body tissues except the brain and cerebrospinal fluid (CSF); in the presence of meningitis, penetration into the CSF increases. Tissue concentrations persist longer than do serum concentrations. Erythromycin concentrates in the bile and liver in patients with normal hepatic function. Because of erythromycin's relatively poor oral absorption, significant concentrations are achieved in the large intestine. Excretion of erythromycin is mainly via the bile, with some reabsorption. Only small amounts are found in the urine, with less than 5% excreted as unchanged drug. In adult patients with normal renal function, the serum half-life is about 1.5 hours.

Where is erythromycin excreted?

Erythromycin is excreted mainly by the liver. Patients with impaired hepatic or biliary function should receive erythromycin with caution.

Does erythromycin increase dihydrocodeine?

Chlorpheniramine; Dihydrocodeine; Pseudoephedrine: (Moderate) Concomitant use of dihydrocodeine with erythromycin may increase dihydrocodeine plasma concentrations, resulting in greater metabolism by CYP2D6, increased dihydromorphine concentrations, and prolonged opioid adverse reactions, including hypotension, respiratory depression, profound sedation, coma, and death. If coadministration is necessary, monitor patients closely at frequent intervals and consider a dosage reduction of dihydrocodeine until stable drug effects are achieved. Discontinuation of erythromycin could decrease dihydrocodeine plasma concentrations, decrease opioid efficacy, and potentially lead to a withdrawal syndrome in those with physical dependence to dihydrocodeine. If erythromycin is discontinued, monitor the patient carefully and consider increasing the opioid dosage if appropriate. Erythromycin is a moderate inhibitor of CYP3A4, an isoenzyme partially responsible for the metabolism of dihydrocodeine.

Can you give erythromycin to a mother?

According to the manufacturer, erythromycin should be used with caution in breast-feeding mothers because it is excreted into breast milk. A prospective observational study assessing the safety of macrolide antibiotics during lactation found that 12.7% (n = 55) of babies exposed to macrolides via breast milk experienced adverse events including rash, diarrhea, loss of appetite, and somnolence. The adverse event rate was similar to that seen in babies in a control group whose mothers were treated with amoxicillin (8.3%). Only 2 mothers in the study received erythromycin, 10 received azithromycin, 6 received clarithromycin, and the remainder were treated with roxythromycin. A population based cohort study found that babies diagnosed with infantile hypertrophic pyloric stenosis were 2.3—3 times more likely to have been exposed to a macrolide antibiotic through breast milk during the first 90 days of life than babies not exposed during that same time period. The study did not specify which antibiotic the mothers of affected babies were prescribed; however, the majority of macrolide prescriptions were for erythromycin (72%), with 7% for azithromycin and 1.7% for clarithromycin. The American Academy of Pediatrics (AAP) considers erythromycin to be a medication that is usually compatible with breast-feeding; azithromycin and clarithromycin have not been evaluated by the AAP. Consider the benefits of breast-feeding, the risk of potential drug exposure, and the risk of an untreated or inadequately treated condition. If a breast-feeding baby experiences an adverse effect related to a maternally ingested drug, healthcare providers are encouraged to report the adverse effect to the FDA.
