Turmeric and Rasagiline

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

Minor

CYTOCHROME P450 1A2 (CYP1A2) SUBSTRATES

Why this applies to Rasagiline

Rasagiline falls under CYTOCHROME P450 1A2 (CYP1A2) SUBSTRATES — the group Turmeric interacts with.

Theoretically, turmeric might increase levels of drugs metabolized by CYP1A2. However, research is conflicting.
In vitro and animal research show that the turmeric constituent, curcumin, inhibits CYP1A2. However, other in vitro research suggests that curcumin does not significantly affect CYP1A2.
Severity Minor 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 rasagiline (Azilect) and turmeric. Rasagiline is cleared from your body mainly by a liver enzyme called CYP1A2. Some early lab and animal research suggests the curcumin in turmeric might slow that enzyme down a little. If that happened in a real person, rasagiline could build up slightly, which in theory might mean more of its effects or side effects like dizziness, low blood pressure when standing, headache, or trouble sleeping.

That said, the evidence here is weak and even conflicting, so I wouldn't lose sleep over it. Everyday turmeric in cooking is very unlikely to matter. If you're taking a concentrated curcumin supplement, just give your pharmacist or doctor a heads-up so they can keep an eye on how you feel.

“Rasagiline (Azilect) treats Parkinson's disease by blocking monoamine oxidase, the same enzyme that clears tyramine from aged and fermented foods. That shared pathway explains most of the 14 major-rated interactions on this page.”

About Turmeric

What is Turmeric?

Turmeric
  • Joint pain and arthritis
  • Inflammation
  • Digestive upset
  • Antioxidant support
  • Skin conditions

Turmeric is a popular spice whose main active compounds, curcuminoids, are studied mostly for inflammation and joint pain. Some research is promising, but quality is mixed and curcumin is poorly absorbed on its own. For most people, dietary amounts are safe, but talk to your pharmacist or doctor before taking concentrated supplements, especially if you are pregnant, nursing, or have a medical condition.

About Rasagiline

What Is Rasagiline Used For?

Brand name: Azilect

Rasagiline tablets — sold as Azilect, Rasagiline, and Rasagiline mesylate — are approved to treat Parkinson's disease (PD). They can be used on their own (monotherapy) or added to other Parkinson's medications, including levodopa.

When used alongside levodopa, rasagiline helps manage Parkinson's symptoms that are not fully controlled by levodopa alone. Your doctor may adjust your levodopa dose when the two are combined.
