Interaction Details
Naproxen is classified as belonging to the following category: Cytochrome P450 1A2 (Cyp1A2) Substrates
There is some concern that turpentine oil can inhibit CYP1A2 enzyme activity by up to 90% via induction of inflammation and subsequent downregulation of CYP activity. However, animal research suggests that turpentine oil does not affect the metabolism of phenacetin, a CYP1A2 substrate, despite inducing inflammation.
Some medications metabolized by CYP1A2 include clozapine (Clozaril), cyclobenzaprine (Flexeril), fluvoxamine (Luvox), haloperidol (Haldol), imipramine (Tofranil), mexiletine (Mexitil), olanzapine (Zyprexa), pentazocine (Talwin), propranolol (Inderal), tacrine (Cognex), theophylline, tizanidine (Zanaflex), zileuton (Zyflo), zolmitriptan (Zomig), and others.

Turpentine Oil Overview
Turpentine oil is a yellowish liquid that is extracted from the resin of some pine trees. It has a strong, pungent aroma and is used in a variety of industrial and commercial applications, including the production of paints, varnishes, solvents, and disinfectants.
Turpentine oil has also been used in traditional medicine as a natural remedy for a variety of ailments. It is thought to have antiseptic, expectorant, and diuretic properties, and it is sometimes used to treat respiratory conditions, such as coughs and bronchitis, as well as skin conditions, such as wounds and fungal infections.
Turpentine oil is most commonly used as a fragrance additive in some over-the-counter medicated chest rubs, such as Vicks VapoRub. It is important to note that turpentine oil can be toxic if ingested or inhaled in large amounts, and it can cause a number of side effects, including nausea, vomiting, dizziness, and difficulty breathing. It should be used with caution and only under the supervision of a healthcare provider.
Naproxen Overview
-
Prescription naproxen is used to relieve pain, tenderness, swelling, and stiffness caused by osteoarthritis (arthritis caused by a breakdown of the lining of the joints), rheumatoid arthritis (arthritis caused by swelling of the lining of the joints), juvenile arthritis (a form of joint disease in children), and ankylosing spondylitis (arthritis that mainly affects the spine). Prescription naproxen tablets, extended-release tablets, and suspension are also used to relieve shoulder pain caused by bursitis (inflammation of a fluid-filled sac in the shoulder joint), tendinitis (inflammation of the tissue that connects muscle to bone), gouty arthritis (attacks of joint pain caused by a build-up of certain substances in the joints), and pain from other causes, including menstrual pain (pain that happens before or during a menstrual period). Nonprescription naproxen is used to reduce fever and to relieve mild pain from headaches, muscle aches, arthritis, menstrual periods, the common cold, toothaches, and backaches. Naproxen is in a class of medications called NSAIDs. It works by stopping the body's production of a substance that causes pain, fever, and inflammation.
