Garlic and Ibuprofen lysine

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

Moderate

ANTICOAGULANT/ANTIPLATELET DRUGS

Why this applies to Ibuprofen lysine

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

Garlic may have antiplatelet effects and may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.
Raw garlic and a variety of garlic extracts have antiplatelet activity and can increase prothrombin time.
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 thing to keep in mind: ibuprofen lysine (NeoProfen) is a form of ibuprofen, an NSAID. Like other NSAIDs, it can make your platelets a little less sticky and can irritate the stomach lining, which already nudges up bleeding risk. Garlic, especially in concentrated supplement form, may also have a mild blood-thinning effect of its own. Put the two together and those small effects can add up.

To be honest, this concern is mostly theoretical, based on how garlic behaves in the lab rather than strong patient studies. Garlic in normal cooking amounts is very unlikely to matter. With garlic supplements, just watch for signs like easy bruising, nosebleeds, or stomach upset, and check with your pharmacist or doctor before combining them.

From our pharmacist’s overview on the Ibuprofen lysine page

“Ibuprofen lysine (NeoProfen) is an injectable form of the NSAID ibuprofen, and this list warrants real attention, starting with its six major entries. The dominant pattern is bleeding: 202 of the 268 ingredients on file can thin the blood or slow clotting, which stacks on an NSAID's own tendency to irritate the stomach and blunt platel…”

About Garlic

What is Garlic?

Garlic
  • High blood pressure
  • High cholesterol
  • Heart health
  • Immune support and common cold
  • Antimicrobial uses

Garlic is a common food and supplement that may modestly help with blood pressure and cholesterol, though the evidence is mixed and effects are usually small. It is generally safe in food amounts, but concentrated supplements can cause stomach upset, breath and body odor, and a higher risk of bleeding. Talk with your pharmacist or doctor before taking garlic supplements, especially if you take other medicines.

About Ibuprofen

What Is Ibuprofen Used For?

Brand name: NeoProfen

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.
