From the Guidelines

It is not recommended to take doxycycline with alcohol, as it can reduce the antibiotic's effectiveness and potentially worsen side effects. According to the CDC guidelines for the diagnosis and management of Q fever 1, patients may take doxycycline with food to avoid stomach upset, but there is no mention of taking it with alcohol. However, it is known that combining alcohol with doxycycline can decrease the antibiotic's half-life in the bloodstream, making it less effective at treating the infection.

Some key points to consider when taking doxycycline include:

  • Taking the medication with food to avoid stomach upset, but avoiding dairy products within 2 hours of taking the medication 1
  • Being aware of potential gastrointestinal side effects like nausea, vomiting, and stomach pain, which may be increased when taking doxycycline with alcohol
  • The importance of completing the full course of antibiotics as prescribed, usually 7-14 days depending on the condition being treated
  • Staying hydrated and avoiding further alcohol consumption until the full course of antibiotics is completed

The standard doxycycline dosage is usually 100mg once or twice daily, as recommended for the treatment of acute and chronic Q fever 1. For the best treatment outcome, it is recommended to avoid alcohol completely during the doxycycline course. If you've already consumed alcohol while on doxycycline, it is essential to continue your medication as prescribed and avoid further alcohol until you've completed the full course of antibiotics.
