Camphor and nilotinib

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

Moderate

HEPATOTOXIC DRUGS

Why this applies to nilotinib

nilotinib falls under HEPATOTOXIC DRUGS — the group Camphor interacts with.

Theoretically, concomitant use of camphor with other hepatotoxic drugs might increase the risk of liver damage.
There have been a few case reports of transient elevations in liver enzymes in adults after oral or topical use of camphor. There has also been one case of hepatotoxicity in an infant after topical camphor use.
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 nilotinib (Tasigna): it's a cancer medicine that can already be tough on your liver, so doctors watch your liver enzymes closely while you take it. Camphor, mostly used in rub-on products for sore muscles and congestion, has been tied to a few reports of liver enzyme bumps too, both from swallowing it and rarely from skin use.

The worry is that stacking two things that can stress the liver might add up. I want to be honest though, this is a theoretical concern based on how these work, not something proven to happen often. Normal topical use is unlikely to cause trouble, and camphor should never be swallowed. Just keep your liver checkups, and run any camphor product past your pharmacist or oncologist first.

About Camphor

What is Camphor?

  • Muscle and joint aches
  • Cough and chest congestion
  • Itching and skin irritation
  • Cold sores or minor wounds
  • Counterirritant for pain

Camphor is a strong-smelling compound from the camphor tree (or made synthetically) that is used in many topical rub-on products for muscle aches, itching, and chest congestion. It can be helpful for these uses when applied to the skin in small, regulated amounts, but it is toxic and potentially deadly if swallowed, so it should never be taken by mouth. Keep camphor products away from children and check with a pharmacist before use.

About Nilotinib

What Is Nilotinib Used For?

Brand name: Tasigna

  • Nilotinib is used to treat certain types of chronic myeloid leukemia (CML; a type of cancer of the white blood cells) who have recently found to have this condition in adults and children 1 year of age and older. It is also used to treat certain types of CML in adults whose disease could not be treated successfully with imatinib (Gleevec) or adults who cannot take imatinib because of side effects. Nilotinib is also used to treat certain types of CML in children 1 year of age or older whose disease could not be treated successfully with other tyrosine kinase inhibitor therapies or who cannot take these medications because of side effects. Nilotinib is in a class of medications called kinase inhibitors. It works by blocking the action of the abnormal protein that signals cancer cells to multiply. This helps to stop or slow the spread of cancer cells.
