Fig and Diphenhydramine

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

Moderate

PHOTOSENSITIZING DRUGS

Why this applies to Diphenhydramine

Diphenhydramine falls under PHOTOSENSITIZING DRUGS — the group Fig interacts with.

Theoretically, fig might increase the risk of photosensitivity when used in combination with photosensitizing drugs.
Many cases of photodermatitis from fig leaf have been reported. Some drugs that also cause photosensitivity include amitriptyline (Elavil), quinolones (Ciprofloxacin, others), sulfa drugs (Septra, Bactrim, others), and tetracycline.
Severity Moderate 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 explains PharmD, Clinical Pharmacist

Here's the gist with fig and diphenhydramine (Benadryl). This isn't about how your body breaks the drug down, so don't worry about your antihistamine getting stronger or weaker. The concern is purely about your skin and sunlight. Fig leaf in particular contains compounds that can make skin more sensitive to the sun, and diphenhydramine is also listed as a drug that can do this. Put them together and, in theory, you might sunburn a little more easily than usual.

I'll be honest though, this one is theoretical, based on how these compounds behave rather than real-world reports of the two combined. Eating a fig or two won't be an issue. Concentrated fig leaf supplements plus a lot of sun exposure is where I'd be more careful. Use sunscreen, and check with your pharmacist if you have questions.

From our pharmacist’s overview on the Diphenhydramine page

“Diphenhydramine (Benadryl, Simply Sleep) is sedating by design, and most of the 147 supplements and herbal ingredients on this list lean into that. Seventy-eight are sedating substances themselves, alcohol and kava the standouts, and stacking them can slow breathing and reflexes well beyond ordinary drowsiness.”

About Fig

What is Fig?

  • Constipation and digestive health
  • Blood sugar support
  • Cough and sore throat
  • Skin conditions (topical sap)
  • Source of fiber and minerals

Fig (Ficus carica) is a common fruit that has long been used as a gentle food remedy for constipation, and its leaves are used traditionally for blood sugar and coughs. The fruit is a safe and nutritious food, but evidence for fig leaf supplements treating specific health conditions is limited. Talk to your pharmacist or doctor before using concentrated fig leaf products, especially if you have diabetes.
