Summer Savory and Naproxen, Pseudoephedrine

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

Moderate

ANTICOAGULANT/ANTIPLATELET DRUGS

Why this applies to Naproxen, Pseudoephedrine

Naproxen, Pseudoephedrine falls under ANTICOAGULANT/ANTIPLATELET DRUGS — the group Summer Savory interacts with.

In vitro research suggests that summer savory extract inhibits platelet aggregation and adhesion. Theoretically, summer savory might increase the risk of bleeding when used with antiplatelet or anticoagulant drugs. Some anticoagulant or antiplatelet drugs include aspirin, clopidogrel (Plavix), dalteparin (Fragmin), enoxaparin (Lovenox), heparin, ticlopidine (Ticlid), warfarin (Coumadin), and others.
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 with Aleve Cold and Sinus: it pairs naproxen (an NSAID pain reliever) with pseudoephedrine (a decongestant). Naproxen on its own can already nudge up your bleeding risk because it makes platelets, the cells that help your blood clot, a bit less sticky. That can show up as easier bruising, nosebleeds, or stomach irritation.

Now, summer savory has been shown in lab dish studies only to also slow platelets a little. So in theory, stacking the two could add up and raise bleeding risk a touch. This is theoretical and not proven in people, and a sprinkle of savory in your cooking is very unlikely to matter. Concentrated extracts or the essential oil are the real question mark. If you use those regularly, check with your pharmacist or doctor first.

From our pharmacist’s overview on the Naproxen, Pseudoephedrine page

“Aleve Cold and Sinus pairs naproxen, an anti-inflammatory painkiller, with pseudoephedrine, a decongestant that acts as a mild stimulant, and that combination is why its supplement list runs to 334 entries and deserves real vigilance. The two biggest themes mirror the two drugs.”

About Summer Savory

What is Summer Savory?

  • Digestive upset and gas
  • Sore throat and cough
  • Antimicrobial
  • Mild diarrhea
  • Seasoning/culinary use

Summer savory is a common kitchen herb that has long been used as a tea or remedy for digestive complaints and minor infections. Food amounts are generally considered safe, but human studies supporting its medicinal use are very limited, so don't rely on it to treat any health condition. Talk with a pharmacist or doctor before using concentrated extracts or the essential oil.
