Celery and Aminolevulinic Acid Hydrochloride

Here is the interaction we found between these two, with the evidence behind it.

Minor

PHOTOSENSITIZING DRUGS

Why this applies to Aminolevulinic Acid Hydrochloride

Aminolevulinic Acid Hydrochloride falls under PHOTOSENSITIZING DRUGS — the group Celery interacts with.

Theoretically, celery might increase the risk of photosensitivity reactions when taken with photosensitizing drugs.
Laboratory research shows that celery contains photosensitizing agents such as phenols and psoralens.
Severity Minor Likelihood Possible Evidence D

Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the thing about aminolevulinic acid (like Ameluz or Gleolan): it's a light-activated medicine. Your skin or the treated area becomes very sensitive to light on purpose so the therapy can work, but that also means you can sunburn easily and get redness, swelling, or stinging if you get too much light exposure afterward.

Celery naturally contains compounds called psoralens, which can also make skin more reactive to sunlight. So in theory, piling celery (especially concentrated seed extract or oil supplements) on top could add a little to that light sensitivity. I'll be honest with you, this is based only on lab research and a few anecdotal reports, so it's a minor, mostly theoretical concern. Eating celery as food is unlikely to matter much. Just follow your sun-protection instructions closely, and mention any supplements to your dermatologist or pharmacist.

From our pharmacist’s overview on the Aminolevulinic Acid Hydrochloride page

“Aminolevulinic acid (Ameluz, Gleolan) works by making targeted cells intensely sensitive to light, so I treat its supplement list with genuine care. Twenty of the 37 interacting ingredients, chlorophyll among them, carry photosensitizing effects of their own, and stacking those on a drug built around light sensitivity risks harsher ski…”

About Celery

What is Celery?

Celery
  • High blood pressure
  • Fluid retention (diuretic)
  • Joint pain and inflammation
  • Anxiety and sleep
  • Digestive support

Celery is a common vegetable that is also taken as a seed extract or oil supplement, mainly for blood pressure, fluid retention, and joint discomfort. Human evidence for these supplement uses is limited and mostly preliminary, so it should not replace proven treatments. Celery is generally safe as food, but concentrated supplements and possible allergic reactions warrant caution.
