Mastic + nilotinib
nilotinib brand name: Tasigna.
We found no known interaction between Mastic and nilotinib in our sources. Absence of a documented interaction is not the same as proven safety, and does not guarantee one does not exist. Do not start, stop, or change a medication or supplement based on this page; confirm with your pharmacist or doctor first. Additionally, although there is no interaction, the two are separately associated with some of the same side effects, which would make a new symptom harder to attribute to one or the other.
Mastic and nilotinib
We checked these two against our interaction database. Here is what we found.
No Known Interaction Found
We did not find a documented interaction between nilotinib and Mastic in our sources. This does not guarantee that the combination is completely free of risk — there is often limited research on supplements and herbal products, especially around drug interactions.
Worth understanding: our licensed dataset holds no drug-interaction record for Mastic at all — not against nilotinib, and not against any other medication we track. This verdict therefore rests on the absence of any recorded data, not on research that looked at this combination and found nothing. We cannot rule an interaction out.
If you decide to take both, the practical routine is simple: add one new thing at a time and note the date you started it. If the combination is going to disagree with you, it usually shows in the first days to a couple of weeks — and a start date turns “I’ve been feeling off” into something a pharmacist can actually work with. Do not stop a prescribed medicine on your own.
Always talk with your pharmacist or doctor before making changes to your medications or supplements, particularly if you take several medications or have an ongoing health condition.

What nilotinib Is Prescribed For, and What Mastic Has Been Studied For
These two come up together because they touch the same health topic — not because they do the same job. nilotinib is a prescription medicine with approved uses on its FDA label. Mastic is a supplement: what follows is what researchers have looked at it for, and how strong that evidence is.
Mastic has been studied for:
-
Cancer studied, not established Mastic has been studied for this. Natural Medicines rates the evidence: Insufficient Reliable Evidence To Rate Read what the research shows
Mastic for cancer
Although there has been interest in using oral mastic for cancer, there is insufficient reliable information about the clinical effects of mastic for this purpose.
Effectiveness ratings and the research summaries above are the verbatim record from the Natural Medicines database, which grades evidence from “Effective” down to “Insufficient Reliable Evidence To Rate”. A rating below the top of that scale means researchers have looked at it — not that it works, and never that it can stand in for a prescribed medicine. Do not stop or replace nilotinib on your own; if you are taking Mastic for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

About Mastic
What is Mastic?
- Indigestion and stomach upset
- Stomach ulcers and H. pylori support
- Oral and gum health
- Bad breath
- General antioxidant/anti-inflammatory support
Mastic is a resin from the mastic tree that has a long history of use for digestive complaints and oral health. Some small studies suggest it may help with indigestion, stomach ulcers, and dental hygiene, but the evidence is limited and not conclusive. It is generally well tolerated in food amounts, but talk to your pharmacist or doctor before using it as a supplement, especially if you are pregnant or breastfeeding.
Pistacia lentiscus · Anacardiaceae · Resin (gum) from the tree; sometimes the essential oil · Capsules, chewable gum/resin tears, powder, essential oil, mouthwash, toothpaste
An interaction check asks whether these two react with each other — it does not ask whether Mastic is a good idea for someone in your situation. Here is what our Mastic record says about it on its own.
Mastic: dosing
There is no official or standardized dose of mastic. Studies have used different forms and amounts, so it is hard to recommend one exact dose. The strength of capsules, powders, and chewing products can vary a lot between brands.The safest approach is to follow the directions on the product label and not exceed the suggested amount. Because supplements are not tightly regulated, choose a reputable brand when possible.

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.
