From the Guidelines
Azithromycin can be taken with or without food, but it is recommended to take it with food to minimize gastrointestinal side effects. When considering the administration of azithromycin, it's essential to weigh the benefits of reduced stomach upset against potential decreases in drug absorption. According to the guidelines for the prevention and treatment of travelers' diarrhea 1, azithromycin is generally well tolerated with minimal side effects, usually dose-related gastrointestinal complaints. Incident or worsening nausea or vomiting are exacerbated by the primary gastrointestinal infection, and are more common than in the treatment of non-gastrointestinal infections, with rates of 3% and <1%, respectively. Some key points to consider when taking azithromycin include:
- The medication is typically absorbed well regardless of food intake, which is one of its advantages as an antibiotic.
- If you experience nausea or stomach discomfort when taking azithromycin on an empty stomach, having it with a meal can help minimize these side effects.
- High-fat meals might slightly decrease the maximum concentration of the drug in your bloodstream, though this usually doesn't affect its overall effectiveness.
- Always take the full course of antibiotics even if you feel better before finishing the prescription.
- Remember to space azithromycin apart from antacids containing aluminum or magnesium by at least 2 hours, as these can reduce the absorption of the antibiotic. It's crucial to follow the prescribed dosage and administration instructions to ensure the effectiveness of the treatment and minimize potential side effects, as outlined in the guidelines for the prevention and treatment of travelers' diarrhea 1.
