Common Uses

Erythromycin belongs to the macrolide class of antibiotics and is effective in treating a variety of bacterial infections. It is also prescribed to help prevent bacterial endocarditis and to reduce the risk of rheumatic fever flare-ups.

Dosage and Directions

Follow your doctor’s instructions exactly when taking erythromycin. Each dose should be taken with a full glass (8 ounces) of water. This medication can be taken either on an empty stomach or with food or milk to reduce stomach upset. Do not crush, chew, or break enteric-coated or delayed-release tablets; swallow them whole.

Precautions

• Antibiotics like erythromycin may cause diarrhea, which can sometimes signal a new infection. Contact your doctor if you experience watery or bloody diarrhea.
• Do not use anti-diarrheal medications unless advised by your healthcare provider.

Contraindications

Do not take erythromycin if you have an allergy to it or if you are currently using medications such as cisapride (Propulsid) or pimozide (Orap). Patients with liver disease or myasthenia gravis may require dose adjustments or additional monitoring. While erythromycin is generally considered safe during pregnancy, inform your doctor if you are pregnant or planning to become pregnant. The drug can pass into breast milk, potentially harming a nursing infant, so discuss use with your healthcare provider if you are breastfeeding.

Possible Side Effects

Seek immediate medical help if you develop signs of an allergic reaction, such as hives, swelling of the face, lips, tongue, or throat, or difficulty breathing. Contact your doctor promptly if you experience any of the following serious effects:

• Chest pain, irregular heartbeat, light-headedness, or fainting
• Nausea, stomach pain, mild fever, loss of appetite, dark urine, pale stools, or jaundice
• Watery or bloody diarrhea

More common, less severe side effects may include nausea, vomiting, diarrhea, stomach discomfort, dizziness, headache, fatigue, vaginal itching or discharge, and mild skin rash or itching.

Drug Interactions

Many medications can interact with erythromycin. Inform your doctor about all prescription drugs, over-the-counter medications, supplements, vitamins, and herbal products you use. Do not start any new medications without consulting your healthcare provider.

Missed Dose

If you miss a dose, take it as soon as you remember. If it is nearly time for your next dose, skip the missed one and continue with your usual schedule. Avoid doubling doses to compensate for missed ones.

Overdose

Seek emergency medical attention if you suspect an overdose. Symptoms may include nausea, vomiting, diarrhea, stomach pain, or hearing problems.

Storage

Store erythromycin at room temperature, protecting it from moisture and heat.
