From the Guidelines
To manage nausea caused by doxycycline, take the medication with a full stomach and a full glass of liquid, and avoid lying down for 1 hour after taking it. This approach is recommended by the CDC in their 2024 clinical guidelines on the use of doxycycline postexposure prophylaxis for bacterial sexually transmitted infection prevention, United States, 2024 1. The guidelines emphasize the importance of counseling patients on the potential side effects of doxycycline, including gastrointestinal intolerance, and providing guidance on actions to take to mitigate these side effects.
Some key points to consider when taking doxycycline to minimize nausea include:
- Taking the medication with a full glass of liquid to help prevent esophagitis and reduce stomach irritation
- Avoiding lying down for 1 hour after taking doxycycline to prevent esophagitis
- Separating the doxycycline dose by at least 2 hours from dairy products, antacids, and supplements that contain calcium, iron, magnesium, or sodium bicarbonate, as these can reduce the absorption of the medication
- Informing your healthcare provider about any other medications you are taking, including over-the-counter medications, to assess for possible drug interactions 1.
It is essential to follow the prescribed dosage and take doxycycline exactly as directed to minimize the risk of side effects and ensure the effectiveness of the treatment. If nausea persists despite these measures, it is crucial to consult your healthcare provider about alternative options, such as anti-nausea medications or switching to an alternative antibiotic.

- Take doxycycline with food, as this can help reduce nausea and emesis 3
- Take doxycycline at night with dinner, as this may result in better tolerance and reduced nausea 3
- Consider using an enteric-coated doxycycline formulation, which may have better gastrointestinal tolerability and reduce nausea and vomiting 4
