Turpentine Oil and Mitomycin

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

Moderate

TOPICAL DRUGS

Why this applies to Mitomycin

Mitomycin falls under TOPICAL DRUGS — the group Turpentine Oil interacts with.

Some in vitro research shows that alpha-pinene, the major constituent of turpentine oil, does not increase the absorption of chlorpromazine or haloperidol when applied topically. However, animal research shows that turpentine oil increases the absorption of ibuprofen when applied topically. Theoretically, applying turpentine oil to the skin along with other medications might increase the effects and side effects of these medications.
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 for Mitomycin. The concern on file is about skin absorption: turpentine oil can act like a penetration booster, meaning it may help whatever sits next to it on the skin soak in a little more. In lab and animal studies it nudged up the absorption of a topical drug like ibuprofen, though it didn't do that for every medicine tested. So this is a theoretical worry, not something proven in people.

This really only matters if you're using a topical or skin-applied form of mitomycin near where turpentine oil is rubbed in. In that case, more getting through the skin could mean more local irritation, redness, or stinging. To be safe, keep turpentine oil away from any area where mitomycin is applied, and run it by your oncology pharmacist or doctor first.

From our pharmacist’s overview on the Mitomycin page

“Activated charcoal is the entry to know first with mitomycin (Mutamycin, Mitosol, Jelmyto), a chemotherapy drug, because charcoal binds medications and can cut the amount the body receives, and it carries this list's only major rating. A weakened dose of a cancer treatment is a real loss, so I would treat these 26 interactions with gen…”

About Turpentine Oil

What is Turpentine Oil?

Turpentine Oil
  • Muscle and joint aches (topical)
  • Cough and congestion (chest rubs)
  • Minor skin conditions
  • Antiseptic
  • Toothache (traditional)

Turpentine oil is a strong-smelling pine resin product used mostly in tiny amounts in topical rubs for muscle aches and congestion. It can be dangerous and even deadly if swallowed, and reliable evidence for health benefits is very limited. Never drink turpentine oil, and only use diluted, purified products on the skin with care.

About Mitomycin

What Is Mitomycin Used For?

Brand names: Mutamycin, Mitosol, Jelmyto

Mitomycin (and its brand Mutamycin) is used intravenously in combination with other chemotherapy drugs to treat disseminated adenocarcinoma (a type of cancer that has spread) of the stomach or pancreas, when other treatments have not worked. It is not intended to replace surgery or radiation therapy.

Mitomycin is also the active ingredient in other products for different uses: Jelmyto treats low-grade upper tract urothelial cancer (cancer of the upper urinary tract); Zusduri treats recurrent low-grade intermediate-risk non-muscle invasive bladder cancer; and Mitosol is used as a surgical aid during certain glaucoma eye surgery. These are separate products with distinct indications and are not interchangeable with the intravenous injection form.
