Antibiotic Administration Guidelines

Introduction to Antibiotic Administration

Taking antibiotics like azithromycin with food may help minimize common gastrointestinal side effects such as nausea, abdominal discomfort, diarrhea, and vomiting, as recommended by the MMWR Recommendations and Reports 1

The standard dosing regimen for adults is typically 500 mg on day 1, followed by 250 mg once daily on days 2-5, as recommended by the CDC and FDA 1
Azithromycin absorption is not significantly affected by food intake, according to the MMWR Recommendations and Reports 1
Azithromycin tablets can be taken with or without food, but patients should be cautioned not to take azithromycin with aluminum or magnesium-containing antacids simultaneously, as these reduce absorption 1
The medication should be taken at least 2 hours before or after antacids, to minimize potential interactions 2

Patients on oral anticoagulants should have their prothrombin times carefully monitored when taking azithromycin, as concomitant administration may potentiate the effects of oral anticoagulants 1
Patients taking medications metabolized by the cytochrome P450 enzyme system (e.g., digoxin, triazolam, ergot alkaloids) should be monitored for potential drug interactions 1
For patients with hepatic impairment, exercise caution as azithromycin is primarily eliminated via the liver, although the strength of evidence for this guideline is not provided

Common side effects of azithromycin include gastrointestinal disturbances (abdominal discomfort, diarrhea, nausea, vomiting), headache, and dizziness, and patients should be monitored for these potential side effects 1
No specific monitoring of drug levels is required for azithromycin, unlike with aminoglycosides or vancomycin, according to general medical guidelines 3
