Eryc (Erythromycin base)

Indications

Eryc is a prescription antibiotic used to treat a variety of bacterial infections. It contains an active ingredient called Erythromycin. Erythromycin belongs to the macrolide antibiotic class of medications. Erythromycin works by binding to the bacteria's ribosomes and preventing the production of proteins, which are essential for the bacteria's survival and reproduction. As a result, the bacteria become unable to multiply and die out.

Use erythromycin and other antibiotics only to treat or prevent infections caused by bacteria, and not viruses, as antibiotics are ineffective against viral infections. Eryc should also be used only under the guidance and supervision of a healthcare professional, as it may interact with other medications or cause side effects in some patients.

Use and Dosage

Eryc is available in capsule form and contains enteric-coated pellets of erythromycin base for oral administration. For maximum absorption, take Eryc on an empty stomach. However, if nausea occurs, you may take it with food or milk. Swallow the capsule whole and do not crush, chew, or break it.

The dosage and duration of treatment will be determined by your medical condition and response to treatment, and in children, it is also based on their age and weight. To ensure optimal effectiveness, take Eryc at evenly spaced intervals and at the same time each day. If Eryc is being used to treat an infection, continue taking the medication until the full prescribed amount is finished, even if symptoms improve before the treatment is complete.

Stopping the medication too soon may result in a recurrence of the infection. If you are taking Eryc to prevent bacterial infections, make sure to follow your doctor's instructions and not discontinue the medication without approval from your doctor.
