You technically can drink alcohol while taking fluconazole, but most medical sources say it’s better to avoid or strictly limit it because of side effects and liver strain.

Quick Scoop

  • No major, direct “do not mix” interaction is known between fluconazole and alcohol.
  • Both can stress your liver and cause similar side effects like nausea, dizziness, and stomach upset, which may get worse together.
  • If you have liver issues, drink heavily, or feel unwell on fluconazole, alcohol is strongly discouraged.
  • A single small drink is unlikely to cause serious harm for most healthy people, but many clinicians still recommend skipping alcohol until treatment is done.

What actually happens if you drink?

Fluconazole is processed in the liver and can rarely cause liver irritation or injury, especially with repeated or high doses or in people with existing liver disease. Alcohol is also processed in the liver, so combining the two adds extra workload and can increase the chance of liver problems in vulnerable people.

You may notice:

  • Stronger nausea, stomach upset, or vomiting
  • More dizziness or feeling “off” after drinking
  • Headache or general fatigue
  • Very rarely, signs of liver trouble: yellow eyes/skin, dark urine, pale stools, severe abdominal pain, or intense fatigue.

If any of those serious signs show up, urgent medical care is needed.

One‑time pill vs longer course

  • Single 150 mg dose (e.g., for vaginal yeast infection): Many sources say a small, moderate drink around this time is usually low risk for otherwise healthy adults, though avoiding alcohol for the rest of the day is still the safest approach.
  • Multiple‑day or high‑dose course (e.g., for systemic or recurrent infections): Stronger reason to avoid alcohol because your liver is working harder and side effects can add up.

When you really should not drink

Strongly avoid alcohol and call your doctor/pharmacist if:

  • You have known liver disease, hepatitis, fatty liver, or very high alcohol use.
  • You are on other medicines that can affect the liver (some statins, TB meds, certain seizure meds, etc.).
  • You start feeling unusually sick on fluconazole (severe nausea, belly pain, dark urine, yellowing skin/eyes).

Practical “safer‑side” tips

If your own doctor has not given specific guidance and you are otherwise healthy:

  1. Prefer to avoid alcohol completely during fluconazole treatment and for at least 24–48 hours after the last dose, especially with multi‑day courses.
  1. If you do drink:
    • Keep it to a small amount (e.g., one standard drink).
    • Drink slowly and with food.
    • Stay well hydrated and watch for any unusual symptoms.
  1. Stop drinking and seek help if you feel unusually dizzy, very unwell, or notice any liver‑warning signs.

Bottom line: There is no strict, absolute ban on drinking with fluconazole, but because of overlapping side effects and liver stress, the safest move—especially if you are unwell or on a longer course—is to skip alcohol and check directly with your own clinician or pharmacist for personalized advice.
