Lime and Rasagiline

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

Moderate

PHOTOSENSITIZING DRUGS

Why this applies to Rasagiline

Rasagiline falls under PHOTOSENSITIZING DRUGS — the group Lime interacts with.

Theoretically, concomitant use of lime oil with photosensitizing drugs may increase the risk of phototoxicity.
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 rasagiline (Azilect) and lime. This isn't about how your body breaks the medicine down or how well it controls your Parkinson's symptoms. Instead, it's about your skin. Lime oil contains compounds (called furocoumarins) that can make skin more sensitive to sunlight, and rasagiline is grouped with drugs that may do the same. Put them together and, in theory, you could sunburn more easily or get a rash on exposed skin.

I want to be honest about the strength of this: it's based on lab work, not real patient cases, so it's more of a theoretical caution than a proven problem. Enjoying lime in food or a drink is very unlikely to matter. If you're applying lime essential oil to your skin and then heading outdoors, use sunscreen and check with your pharmacist.

From our pharmacist’s overview on the Rasagiline page

“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 Lime

What is Lime?

Lime
  • Source of vitamin C
  • Digestive upset
  • Skin care
  • Mood and aromatherapy
  • Flavoring and food preservation

Lime is a common citrus fruit and a good natural source of vitamin C and plant antioxidants. As a food it is generally safe and enjoyed by most people, but evidence that lime treats any specific health condition is limited. Use the essential oil with care, and check with your pharmacist or doctor before using concentrated lime products for health reasons.
