Fig and Promethazine

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

Moderate

PHOTOSENSITIZING DRUGS

Why this applies to Promethazine

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

Here's the simple version: both fig leaf and promethazine (Phenergan) can make your skin more sensitive to sunlight. Promethazine already carries a known risk of sunburn-like reactions, rashes, or redness when you're out in bright sun. Fig leaf has been linked to skin reactions too, so using them together might add up and make you burn or break out more easily in the sun.

I want to be honest about how solid this is. This concern is theoretical, based on how each one behaves rather than real reports of the two combined. Eating figs as a normal food is very unlikely to matter. The bigger question is concentrated fig leaf products or rubbing fig leaf on your skin. If you take both, just use good sun protection and check with your pharmacist or doctor.

From our pharmacist’s overview on the Promethazine page

“Promethazine (Phenergan) is a phenothiazine antihistamine used for allergies, nausea, and motion sickness, and it is strongly anticholinergic on its own, causing dry mouth, blurred vision, drowsiness, and constipation. That is why the 83 supplements and herbs on this list deserve real attention, starting with the three rated major.”

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.

About Promethazine

What Is Promethazine Used For?

Brand name: Phenergan

Promethazine is used for a wide range of conditions. Tablets, oral solution, and rectal suppositories (brands including Phenergan, Promethegan, and Phenadoz) are approved for seasonal and perennial allergic rhinitis, vasomotor rhinitis, allergic conjunctivitis, hives (urticaria), angioedema, dermographism, and allergic reactions to blood or plasma. They are also used for motion sickness (both prevention and active treatment), nausea and vomiting related to anesthesia and surgery, sedation, and as a helper medication alongside pain relievers after surgery.

Promethazine hydrochloride injection (brands including Phenergan and Promethazine HCl injection) is used for many of the same purposes but is reserved for situations where oral treatment is not possible — including allergic emergencies as an adjunct to epinephrine, sedation during labor, and as an aid during certain surgical procedures such as bronchoscopy and eye surgery.
