Rue and Interferon Gamma-1b

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

Moderate

PHOTOSENSITIZING DRUGS

Why this applies to Interferon Gamma-1b

Interferon Gamma-1b falls under PHOTOSENSITIZING DRUGS — the group Rue interacts with.

Theoretically, rue might increase the risk for phototoxicity when used with photosensitizing drugs.
Rue contains photosensitizing furanocoumarins and psoralens and has been associated with multiple reports of phototoxic reactions. There is also one case report of an increased phototoxic response to psoralen and ultraviolet A (PUVA) therapy associated with ingestion of rue.
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 gist with Actimmune (interferon gamma-1b) and rue. This isn't about your liver breaking the medicine down or one speeding up the other. The concern is purely about your skin and the sun. Rue naturally contains furanocoumarins and psoralens, plant compounds that can make your skin much more sensitive to sunlight. Interferon products are grouped among medicines that can also make you sun-sensitive, so stacking the two could, in theory, raise your odds of a quick, exaggerated sunburn or a phototoxic skin reaction.

Honestly, the evidence here is thin (mostly scattered case reports), so I don't want to alarm you. Still, it's an easy thing to play it safe with: use sunscreen, cover up, and check with your doctor or pharmacist before mixing rue with this injection.

From our pharmacist’s overview on the Interferon Gamma-1b page

“Liver injury is the first thing to understand about supplements and interferon gamma-1b (Actimmune), a drug given for serious immune conditions that can strain the liver on its own. All three major-rated interactions here point that way: Siberian cocklebur, an herb linked to liver failure, plus alcohol in the form of beer and wine.”

About Rue

What is Rue?

Rue
  • Menstrual cramps
  • Digestive upset
  • Muscle spasms and pain
  • Headache
  • Insect repellent (topical)
  • Traditional folk remedy

Rue is a strong-smelling herb from southern Europe with a long history in folk medicine, but there is very little reliable human research to support its health uses. It can be toxic in larger amounts and is considered unsafe during pregnancy, so most people should avoid it or use it only under professional guidance.

About Interferon Gamma-1b Injection

What Is Interferon Gamma-1b Injection Used For?

Brand name: Actimmune

Actimmune (interferon gamma-1b) is approved for two specific inherited conditions. First, it reduces how often and how severely serious infections occur in people with chronic granulomatous disease (CGD) — a rare inherited disorder where certain immune cells can't fight off infections properly.

Second, Actimmune is used to delay disease progression in patients with severe, malignant osteopetrosis (SMO) — a rare inherited bone disorder where bones become abnormally dense and the immune system doesn't work as it should.
