Erythromycin: Uses, Dosage, Safety, and Prescription Information

Erythromycin is a prescription macrolide antibiotic used for selected infections caused by susceptible bacteria. It does not treat viral illnesses. The diagnosis, culture information when available, allergy history, and interaction profile should guide antibiotic selection.

An Erythromycin price varies by strength, formulation, pharmacy, and insurance. Patients may buy Erythromycin only with a valid prescription. An Erythromycin price does not establish that an antibiotic is appropriate.

Indications

Erythromycin may be prescribed for specific respiratory, skin, or other bacterial infections and selected prevention indications. Take it only for a proven or strongly suspected bacterial infection and complete the prescribed course unless the prescriber changes it. Patients can buy Erythromycin from a regulated pharmacy after evaluation; the Erythromycin price is secondary to correct treatment.

Dosage

Formulations have different instructions. Delayed-release tablets must be swallowed whole and should not be crushed, chewed, or divided. Adult regimens may use 250 mg, 333 mg, or 500 mg at intervals chosen for the infection. Patients with a valid prescription can buy Erythromycin 250 mg, Erythromycin 333 mg, or Erythromycin 500 mg when each strength matches the prescribed regimen. Do not double a missed dose.

Safety Information

Tell the prescriber about liver disease, myasthenia gravis, heart-rhythm problems, low potassium or magnesium, pregnancy, breastfeeding, and all medicines. Erythromycin can prolong QT and cause serious arrhythmias. Seek urgent care for palpitations, fainting, chest pain, severe watery or bloody diarrhea, jaundice, severe rash, or allergic swelling.

Interactions

Erythromycin has clinically important interactions, including with some statins, antiarrhythmics, anticoagulants, colchicine, certain calcium-channel blockers, and CYP3A4-metabolized medicines. Do not use with contraindicated interacting products such as pimozide. A pharmacist should screen all medicines before patients buy Erythromycin. The Erythromycin price is less important than interaction safety.
