What is Erythrocin?

Erythrocin is an antibiotic (sold under the trade names Erythromycin, E-Mycin, Ethril, Ilosone or Pediamycin) derived from the Streptomyces erythreus actinomycete.

How to take Erythrocin?

Erythrocin is an oral medication, usually prescribed in the form of a 250 mg coated tablet, although a suspension is available for infants.

Take each tablet just before or with meals to avoid an upset stomach. Swallow each tablet whole with a glass of water.
