Can you drink alcohol while taking Aminolevulinic acid?
Last updated September 7, 2026.
Alcohol has no known direct interaction with aminolevulinic acid, so a drink is usually acceptable, but timing around your treatment matters more than the drink itself. The form you are given changes the picture. Topical products such as Levulan Kerastick and Ameluz are activated by light, and your treated skin stays very sensitive to sunlight and bright indoor light for roughly 40 to 48 hours after application. Alcohol widens blood vessels, so it can make the flushing, stinging, and swelling in a treated area feel stronger, and it makes it easier to skip the sun precautions that protect your skin. The oral form, Gleolan, is taken a few hours before brain tumor surgery, so your fasting, anesthesia, and alcohol instructions come from the surgical team. Tell your clinician if you drink daily, have liver disease, or take other medicines that raise light sensitivity.
What to do
- Protect the light window first: Stay out of sunlight and bright indoor light for the full 40 to 48 hours your product specifies, whether or not you drink.
- Skip drinks on treatment day: Alcohol adds flushing and warmth to skin that is already stinging and swollen, so wait until the reaction settles.
- Follow surgical instructions exactly: If you are taking oral Gleolan before a procedure, your fasting and alcohol rules come from the surgical and anesthesia team.
- Report heavy or daily drinking: Regular alcohol use and liver disease are worth telling your clinician about before treatment, since liver blood tests can shift temporarily.
- Check your other medicines: Some antibiotics, diuretics, and acne drugs also increase light sensitivity, so review your full list before your appointment.
- Know when to call: Contact your clinician for severe pain, spreading blistering, signs of infection, or yellowing of the skin or eyes.
