Fig and Sulfasalazine

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

Moderate

PHOTOSENSITIZING DRUGS

Why this applies to Sulfasalazine

Sulfasalazine 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 thing to know about pairing fig with sulfasalazine: this isn't about your blood levels of the drug going up or down. Sulfasalazine on its own can make your skin more sensitive to the sun, meaning you may burn faster or break out in a rash with less sun exposure than usual. Fig, especially concentrated fig leaf products and the sap, has also been linked to sun-triggered skin reactions (photodermatitis). Put them together and you could, in theory, be a bit more prone to that.

To be fair, this is a theoretical concern based on how each one behaves, not strong proof. Eating figs as food is very unlikely to be an issue. If you use fig leaf supplements, just practice good sun habits (sunscreen, a hat) and check with your pharmacist or doctor before stopping anything.

See Every Supplement That Interacts With Sulfasalazine

This page covers Fig only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Sulfasalazine page lists 39 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Alfalfa (moderate), Angelica Archangelica (moderate), Arrach (moderate) and Bergamot (moderate).

By severity: 1 major · 28 moderate · 10 minor.

From our pharmacist’s overview on the Sulfasalazine page

“Activated charcoal is the single major-rated risk for sulfasalazine (Azulfidine), because charcoal can bind the drug in the gut and cut how much your body absorbs, weakening a medicine people rely on for rheumatoid arthritis or ulcerative colitis. That entry alone earns this list of 39 supplements and herbs a careful read.”

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 Sulfasalazine

What Is Sulfasalazine Used For?

Brand names: SAS, Azulfidine EN-Tabs, Azulfidine

Sulfasalazine tablets (Azulfidine and generic) treat mild to moderate ulcerative colitis and are used as an add-on therapy in severe ulcerative colitis. They also help keep ulcerative colitis in remission — reducing the frequency of flare-ups.

The delayed-release tablets (Azulfidine EN-tabs and generic delayed-release) have the additional approvals of treating rheumatoid arthritis in adults who haven't responded well enough to NSAIDs or salicylates, and polyarticular-course juvenile rheumatoid arthritis in children who also haven't responded adequately to those drugs.
