Grape and Ibuprofen

These two interact in 2 distinct ways. Each one is explained separately below.

Why Are There 2 Interactions?

Grape interacts with whole categories of medication. Ibuprofen falls into 2 of those categories, so it can interact with Grape in 2 different ways. We’ve listed each one below — your overall risk is driven by the most serious of them (Moderate).

Moderate

ANTICOAGULANT/ANTIPLATELET DRUGS

1 of 2

Why this applies to Ibuprofen

Ibuprofen falls under ANTICOAGULANT/ANTIPLATELET DRUGS — the group Grape interacts with.

Theoretically, grape extracts may have antiplatelet effects and may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.
In vitro evidence suggests that grape extracts might decrease platelet aggregation.
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 explains PharmD, Clinical Pharmacist

Here's the thing to know about pairing a grape supplement with ibuprofen (Advil, Motrin). Ibuprofen is an NSAID, and one of its well-known quirks is that it makes your platelets a little less sticky, so it already nudges up the chance of bleeding or bruising. Lab studies hint that concentrated grape extracts (like grape seed extract) may do something similar and slow platelet clumping too.

Stacked together, the worry is mainly additive: easier bruising, nosebleeds, or stomach upset and bleeding. I'll be honest though, this is based only on test-tube research, so it's theoretical. Eating grapes or drinking a little juice almost certainly won't matter. If you take a strong grape supplement daily, just mention it to your pharmacist or doctor first.

CYTOCHROME P450 2C9 (CYP2C9) SUBSTRATES

2 of 2

Ibuprofen also falls under CYTOCHROME P450 2C9 (CYP2C9) SUBSTRATES.

It is unclear if grape juice or grape seed extract inhibits CYP2C9; research is conflicting.
In vitro evidence shows that grape seed extract or grape juice might inhibit CYP2C9 enzymes. However, a small pharmacokinetic study in healthy adults shows that drinking 8 ounces of grape juice once does not affect the clearance of flurbiprofen, a probe-drug for CYP2C9 metabolism. The effects of continued grape juice consumption are unclear.
Severity Minor Likelihood Unlikely Evidence D

Interaction has been demonstrated in animal or in lab research but has been shown not to occur in humans..

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the short version: your body uses an enzyme called CYP2C9 to break down ibuprofen. Some lab studies hint that grape seed extract or grape juice might slow that enzyme down a little. If that happened, ibuprofen could hang around longer than usual, which in theory could nudge up its common side effects like stomach upset, heartburn, or fluid retention.

But I want to be honest about the evidence here. This concern comes mostly from test-tube data, and a small human study found that real grape juice did not actually change how a similar drug was cleared. So for most people, enjoying grapes or grape juice is very unlikely to cause a problem. If you take ibuprofen often or use concentrated grape seed supplements, just mention it to your pharmacist or doctor.

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.

About Grape

What is Grape?

Grape
  • Antioxidant support
  • Heart and circulation health
  • Vein problems (such as varicose veins)
  • Eye health
  • General anti-inflammatory support

Grapes and grape products like grape seed extract contain antioxidant compounds such as resveratrol and proanthocyanidins that may support heart and blood vessel health. While the food is healthy and generally safe, the supplement evidence for treating specific conditions is mostly limited or preliminary. Talk with your pharmacist or doctor before starting a grape supplement.

About Ibuprofen

What Is Ibuprofen Used For?

Brand names: Motrin, Children's Motrin, Advil, Children's Advil, Fenbid Forte Gel, Ibugel Forte, Arthrofen, Ebufac, Rimafen, Calprofen, Fenpaed, Galprofen, Nurofen for Children, Orbifen for Children, Brufen, Brufen Retard, Fenbid, Tab-Profen, Ibuprofen, Calodor

Oral ibuprofen products (tablets, coated tablets, and liquid-filled capsules) are used to temporarily relieve minor aches and pains from headache, backache, toothache, muscular aches, menstrual cramps, minor arthritis pain, and the common cold, and to temporarily reduce fever. The oral prescription tablet (Ibu) is also indicated for the signs and symptoms of rheumatoid arthritis and osteoarthritis, mild to moderate pain, and primary dysmenorrhea (painful periods).

Caldolor, an intravenous (IV) form, is approved for adults and children 3 months and older to manage mild to moderate pain, to manage moderate to severe pain alongside opioid pain medicines, and to reduce fever. A separate intravenous solution, Ibuprofen Lysine, is used specifically in premature infants to close a patent ductus arteriosus (PDA) — an abnormal blood vessel connection near the heart — when standard medical management has not worked.
