Capsicum and Ticagrelor

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

Moderate

ANTICOAGULANT/ANTIPLATELET DRUGS

Why this applies to Ticagrelor

Ticagrelor falls under ANTICOAGULANT/ANTIPLATELET DRUGS — the group Capsicum interacts with.

Theoretically, capsicum may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.
In vitro research shows that capsicum might increase the effects of antiplatelet drugs. Also, population research shows that capsicum is associated with an increased risk of self-reported bleeding in patients taking warfarin. However, clinical research shows that taking a single dose of capsaicin (Asian Herbex Ltd.), the active ingredient in capsicum, 400-800 mcg orally in combination with aspirin 500 mg does not decrease platelet aggregation when compared with taking aspirin 500 mg alone. Also, there was no notable effect on measures of platelet aggregation with capsaicin. It is unclear whether capsaicin must be used in more than a single dose to affect platelet aggregation.
Severity Moderate Likelihood Possible Evidence B

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 explains PharmD, Clinical Pharmacist

Ticagrelor (Brilinta) already does an important job: it keeps your platelets from clumping together so you don't form a dangerous clot after a heart attack, stent, or stroke. The thinking here is that capsicum, the active part of chili peppers, may also nudge platelets in that same direction, so stacking the two could add up to a slightly higher chance of bleeding or bruising.

Honestly, the evidence is thin and mostly theoretical. Lab studies hint at an effect, but a human study using capsaicin with aspirin didn't show meaningful changes. Chili in your food is very unlikely to matter. Concentrated capsicum supplements are the bigger question mark. Watch for easy bruising, nosebleeds, or bleeding gums, and check with your pharmacist or doctor before adding a supplement.

What These Ratings Mean

Every interaction above is graded three ways — here’s the key to each label.

Severity how clinically significant the interaction is
Major

Clinically significant. Avoid the combination, or use only under close professional supervision.

Moderate

Usually worth avoiding or managing — may need monitoring, a dose change, or timing apart.

Minor

Generally not serious. Be aware of it and mention it to your pharmacist.

Likelihood how strong the evidence is that the interaction actually happens in people
  • LikelyWell-controlled human studies have demonstrated the likely existence of this interaction.
  • ProbableInteraction has not been documented in well-controlled studies, however, the interaction has been demonstrated in some small human studies or in controlled animal studies in conjunction with multiple case reports.
  • PossibleInteraction 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.
  • UnlikelyInteraction has been demonstrated in animal or in lab research but has been shown not to occur in humans.
Evidence the quality of the studies behind the rating (graded A–D)
  • AHigh-quality meta-analysis (quantitative systematic review).
  • BCase-control study.
  • CConsensus.
  • DAnecdotal evidence.

By severity: 5 major · 241 moderate · 40 minor.

From our pharmacist’s overview on the Ticagrelor page

“Grapefruit sits at the top of this list for good reason. Ticagrelor (Brilinta) is cleared by the CYP3A4 enzyme, and grapefruit blocks that enzyme, so drug levels can climb and bleeding becomes more likely.”

About Capsicum

What is Capsicum?

  • Nerve pain (neuropathy)
  • Muscle and joint pain (arthritis)
  • Back pain
  • Digestive support
  • Cluster headache (intranasal)

Capsicum (chili pepper) contains capsaicin, which is best known and best studied as a topical treatment for certain types of pain. Topical capsaicin products are supported by reasonable evidence for some nerve and joint pain, but oral supplements are far less proven. Use it carefully, follow product directions, and talk to your pharmacist or doctor before starting.

About Ticagrelor

What Is Ticagrelor Used For?

Brand name: Brilinta

Ticagrelor tablets are used to lower the risk of cardiovascular death, heart attack, and stroke in adults who have had an acute coronary syndrome (ACS — a sudden reduction of blood flow to the heart) or a previous heart attack. They also reduce the risk of stent thrombosis (a blood clot forming in a coronary stent) in people stented during ACS treatment.

Ticagrelor tablets are also used to reduce the risk of a first heart attack or stroke in people with coronary artery disease (CAD) who are at high risk — including those with type 2 diabetes. Brilinta is additionally indicated to reduce the risk of stroke in adults with a mild acute ischemic stroke or a high-risk transient ischemic attack (TIA, sometimes called a "mini-stroke").
