Frequently Asked Questions

What infections does Erythromycin treat?

Erythromycin (erythromycin) is a macrolide antibiotic used for community-acquired pneumonia, atypical respiratory infections (Mycoplasma, Chlamydia, Legionella), pertussis (whooping cough), Streptococcal pharyngitis in penicillin-allergic patients, skin and soft tissue infections, acne, and selected genitourinary infections including non-gonococcal urethritis. It is also a key option in erythromycin-containing Helicobacter pylori eradication regimens.

How long do I need to take Erythromycin?

Typical courses run 5–14 days depending on the infection. Take it consistently spaced (every 8 or 12 hours depending on the regimen). Macrolides have a long post-antibiotic effect — even after the last dose, tissue levels remain therapeutic for several days.

What are the most common side effects?

Macrolides are well known for GI effects — nausea, abdominal cramping, and diarrhoea — because they directly stimulate gut motilin receptors. erythromycin also has a class warning for QT-interval prolongation; avoid combination with other QT-prolonging drugs (citalopram, certain antipsychotics, quinolones, methadone) and discuss with your clinician if you have known long-QT, electrolyte disturbance, or significant cardiac disease.

Does Erythromycin interact with other medicines?

Macrolides (especially erythromycin and clarithromycin) are strong CYP3A4 inhibitors, raising blood levels of statins (simvastatin and lovastatin should be paused), warfarin, certain calcium-channel blockers, ergot alkaloids (avoid completely), pimozide (avoid), and several immunosuppressants. Provide a full medication list to your prescriber.

Can I take Erythromycin during pregnancy?

erythromycin is generally considered acceptable during pregnancy when clinically needed — safety data are extensive. Erythromycin estolate (a specific salt) is avoided in pregnancy due to maternal hepatotoxicity, but other formulations are acceptable. Always confirm with the prescriber.

Can I drink alcohol while taking Erythromycin?

There is no direct disulfiram-like reaction with macrolides, but moderate to heavy alcohol can worsen GI side effects and is best minimised during the course.
