Turpentine Oil and Mafenide

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

Moderate

TOPICAL DRUGS

Why this applies to Mafenide

Mafenide 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 simple version. Mafenide (Sulfamylon) is a cream you spread on burned skin to help keep infection away. The worry with turpentine oil is that it can act like a skin penetration helper. In animal studies it pushed more ibuprofen through the skin, so in theory it could let more mafenide soak in too. More mafenide getting into your body could mean more of its known issues, like stinging or burning at the site, skin rash, and at higher absorbed amounts a change in your blood's acid balance (metabolic acidosis) that can leave you breathing fast.

Keep in mind this is theoretical and based only on lab and animal work, not people. Mafenide is not a prodrug, so it doesn't need activating. Still, please don't layer turpentine products onto burned or broken skin without checking with your doctor or pharmacist first.

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.
