Turpentine Oil and Minocycline

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

Moderate

TOPICAL DRUGS

Why this applies to Minocycline

Minocycline 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 with turpentine oil and minocycline: turpentine oil is a skin penetration helper, meaning it can loosen up the skin barrier and let things soak through more easily. The concern is mostly about topical products. If you ever applied a minocycline-containing topical alongside a turpentine rub on the same patch of skin, in theory more of the drug could get absorbed, which could nudge up its effects and side effects.

Honestly though, this is shaky, theoretical evidence drawn from lab and animal studies (with ibuprofen, not minocycline), so I wouldn't lose sleep over it. Most folks take minocycline as a pill, where a skin rub won't change much. Still, keep turpentine oil off any area where you apply a medicated cream, and check with your pharmacist if you're unsure.

From our pharmacist’s overview on the Minocycline page

“This is one of the longer interaction lists I review, and with minocycline it earns real care rather than a shrug. Most entries pair this tetracycline antibiotic, taken for acne and other infections, with supplements that raise bleeding risk, and a second sizable group, beer and wine included, can add strain on the liver.”

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 Minocycline

What Is Minocycline Used For?

Brand names: Vectrin, Dynacin, Minocin, Minocin IV, Solodyn, Acnamino MR, Minocin MR, Sebomin MR, Aknemin, Arestin Miscrosperes, Amzeeq, Zilxi

Minocycline is mainly used for infections caused by susceptible bacteria. Oral capsules and tablets, and Minocin intravenous (IV), are labeled for many infections. These include rickettsial infections such as Rocky Mountain spotted fever, Mycoplasma pneumoniae respiratory infections, chlamydia-related infections, plague, tularemia, cholera and brucellosis (with streptomycin). Some gram-negative bacterial infections are included when lab testing shows the bacteria respond.

Other minocycline products are not for infections at all. Extended-release tablets (including Minolira) treat inflammatory acne lesions in patients 12 and older. Amzeeq foam treats inflammatory acne in patients 9 and older. Zilxi foam and Emrosi capsules treat inflammatory rosacea lesions in adults. Arestin is placed in gum pockets by a dental professional for adult periodontitis.
