In short

  • Drinking moderate amounts of alcohol is unlikely to affect anti-malarial medication.
  • But if you drink excessively, you may affect how the medication metabolised by the body.
  • The way the medication is metabolised means that you may reduce the effectiveness of the medication, or you may feel the effects of alcohol more quickly.

Drinking moderate amounts of alcohol is unlikely to affect anti-malarial medication. But if you drink excessively, you may affect how the medication metabolised by the body. The way the medication is metabolised means that you may reduce the effectiveness of the medication, or you may feel the effects of alcohol more quickly.

You should also be aware that drinking alcohol can affect your judgement, and you may be more likely to misuse a mosquito net or repellent or forget to take your medication or use preventative measures altogether.

Always read the patient information leaflet for up to date guidance and consult your doctor if you have any further questions relating to your medication.
