Erythromycin.net is an independent, non-commercial reference website about one medicine: the macrolide antibiotic erythromycin. It brings together how the drug works, how it is dosed, and what its risks are, drawing on regulatory labeling and published clinical guidelines, in language that patients, students and clinicians can all use.
What This Site Is (and Is Not)
The site focuses on a single drug so that each topic can be covered in depth: its mechanism of action, spectrum and resistance, formulations and dosing, special populations, and safety.
- Independent. The site is not affiliated with, funded by or endorsed by any pharmaceutical manufacturer, pharmacy, distributor or healthcare provider.
- Non-commercial. Erythromycin.net does not sell medication, does not link to online pharmacies, and does not earn commissions from product links.
- No sponsored content. No page is paid for, sponsored or written to promote a product, brand or service. Brand names appear only to identify products described in official labeling.
- Not a medical service. The site cannot diagnose conditions, recommend treatment for an individual, or answer personal medical questions.
Who It Is For
The content is written for three overlapping audiences:
- Patients and caregivers who have been prescribed erythromycin and want to understand the medicine, its side effects and its interactions. Most pages open with a plain-language answer.
- Students in medicine, pharmacy, nursing and related fields studying macrolide pharmacology.
- Healthcare professionals looking for a quick, referenced summary. Clinical detail follows the plain-language introduction on each page.
The site is not directed at children.
Editorial Standards
Erythromycin is a prescription medicine, and errors in drug information can cause harm. Content therefore follows a source hierarchy, with higher-level sources taking precedence when they disagree:
- Regulatory labeling. Official prescribing information, such as U.S. FDA-approved labeling published on DailyMed, is the primary reference for indications, dosing, contraindications, warnings and interactions.
- National and international guidelines. For example, the CDC Sexually Transmitted Infections Treatment Guidelines, the American Academy of Pediatrics Red Book, the British National Formulary and NICE guidance, and the WHO Model List of Essential Medicines.
- Systematic reviews and meta-analyses, where guidance is absent or needs context.
- Primary studies, used to explain mechanisms or history, not to override labeling or guidelines.
Further principles applied to every page:
- Statistics, doses and recommendations are taken from identifiable sources. Where reliable figures are not available, the text describes findings qualitatively rather than inventing numbers.
- Where guidance has changed, for example where erythromycin has been replaced by other drugs in a guideline, the current recommendation is stated and older practice is identified as such.
- Off-label uses, such as erythromycin for gastroparesis, are clearly labeled as off-label.
- Regional differences (for example, U.S. versus U.K. product availability) are noted where they matter.
- Each page lists its references so readers can check the original source.
The site does not claim review by a named physician or a medical review board. Readers should treat it as a referenced summary and confirm decisions with a clinician or pharmacist.
How Pages Are Updated
Each page shows a last-updated date. Content is periodically reviewed against current product labeling and the latest editions of the guidelines listed above. A page is revised when labeling changes, a guideline is updated, or an error is reported. The date reflects the most recent substantive review or revision, not cosmetic changes.
Corrections Policy
Accuracy matters more than anything else on a medical reference site. If you believe something on Erythromycin.net is wrong, outdated or unclear, please contact the site by email at privacy@erythromycin.net (the address also listed in the privacy policy). Helpful reports include:
- the page address and the sentence in question;
- what you believe is incorrect; and
- a supporting source, ideally current labeling or a guideline.
Reports are checked against the source hierarchy above. Confirmed errors are corrected promptly and the page's last-updated date is revised. Please do not send personal health information; the site cannot provide individual medical advice.
Advertising and Analytics Disclosure
Erythromycin.net does not display advertising, does not participate in advertising networks, and does not accept payment for placement of content or links. The site uses Google Analytics (GA4) to collect aggregate traffic statistics, such as which pages are visited, so that the most-used content can be prioritized for review. Site visitors are not asked for personal or health information. For details on data handling, see the privacy policy.
Medical Disclaimer
All content is provided for general educational purposes. It may not reflect the most recent labeling in every country, and it cannot account for an individual's medical history, other medicines, allergies, pregnancy or breastfeeding status, or local antibiotic resistance patterns. Never start, stop or change a medicine based on information from this site. Always follow the advice of your prescriber or pharmacist and the patient information leaflet supplied with your medicine. In an emergency, such as a severe allergic reaction, fainting or a very fast or irregular heartbeat, seek urgent medical care.
Machine-Readable Summary (llms.txt)
A plain-text overview of the site's structure and key pages is available at /llms.txt, following the emerging llms.txt convention.
