Know the basics

What is erythromycin used for?

Erythromycin is used to treat a wide variety of bacterial infections. Erythromycin may also be used to prevent certain bacterial infections. Erythromycin is known as a macrolide antibiotic. It works by stopping the growth of bacteria.

Erythromycin treats or prevents only bacterial infections. Erythromycin will not work for viral infections (such as common cold, flu). Unnecessary use or misuse of any antibiotic can lead to its decreased effectiveness.

OTHER USES: This section contains uses of this drug that are not listed in the approved professional labeling for the drug but that may be prescribed by yourhealth care professional. Use erythromycin for a condition that is listed in this section only if it has been so prescribed by your health care professional.

Erythromycin may also be used to treat a certain type of stomach condition involving slowed digestion (gastroparesis).

How should I take erythromycin?

Take erythromycin by mouth as directed by your doctor, usually before a meal. Erythromycin is best absorbed when taken on an empty stomach. If nausea occurs, you may take erythromycin with food or milk.

This medication has a bitter taste if crushed. Swallow the medication whole. Do not chew or crush.

The dosage and length of treatment are based on your medical condition and response to treatment. In children, the dosage is also based on age and weight.

Antibiotics work best when the amount of medicine in your body is kept at a constant level. Therefore, take erythromycin at evenly spaced intervals. To help you remember, take it at the same time(s) each day.

If you are using erythromycin to treat an infection, continue to take erythromycin until the full prescribed amount is finished, even if symptoms disappear after a few days. Stopping erythromycin too early may result in a return of the infection. Tell your doctor if your condition persists or worsens.

If you are taking erythromycin to prevent certain bacterial infections, take it exactly as directed by your doctor. Do not stop taking the medication without your doctor’s approval

How do I store erythromycin?

Erythromycin is best stored at room temperature away from direct light and moisture. To prevent drug damage, you should not store erythromycin in the bathroom or the freezer. There may be different brands of erythromycin that may have different storage needs. It is important to always check the product package for instructions on storage, or ask your pharmacist.
