Sage and Ranitidine Bismuth Citrate

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

Moderate

P-GLYCOPROTEIN SUBSTRATES

Why this applies to Ranitidine Bismuth Citrate

Ranitidine Bismuth Citrate falls under P-GLYCOPROTEIN SUBSTRATES — the group Sage interacts with.

Theoretically, sage might increase levels of drugs transported by P-glycoprotein.
In vitro research suggests that common sage (Salvia officinalis) can inhibit the multi-drug transporter protein, P-glycoprotein. This effect has not been reported in humans.
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 gist for Tritec (ranitidine bismuth citrate). Your body uses a tiny pump called P-glycoprotein to move certain drugs around and push some of them back out. In test-tube studies, sage seems to slow that pump down. If that happened in people, a little more of the drug could stay in your system instead of being shuttled out, which in theory could nudge levels up slightly.

That said, this is only laboratory data and has never actually been seen in humans. Ranitidine is also usually a gentle, well-tolerated medicine (mild side effects like headache or constipation), so I wouldn't lose sleep over sage in your cooking. Concentrated sage extracts or the essential oil are a different story. If you take those regularly, just mention it to your pharmacist or doctor.

About Sage

What is Sage?

Sage
  • Sore throat and mouth irritation
  • Digestive upset
  • Excessive sweating
  • Memory and thinking
  • Menopause symptoms (hot flashes)
  • General antioxidant support

Sage is a common kitchen herb that is generally safe in food amounts and is traditionally used for sore throats, digestion, sweating, and memory. Some early research is encouraging for sore throat and menopausal hot flashes, but most uses are not well proven. Concentrated extracts and the essential oil should be used carefully because high doses contain a compound called thujone, which can be harmful.

About Ranitidine

What Is Ranitidine Used For?

Brand name: Tritec

Ranitidine is used to treat several acid-related stomach and esophageal conditions. These include active duodenal ulcers (ulcers in the small intestine) and benign gastric ulcers (stomach ulcers), GERD (gastroesophageal reflux disease, or chronic acid reflux), erosive esophagitis (irritation and damage to the esophagus from acid), and pathological hypersecretory conditions — rare disorders where the stomach produces too much acid, such as Zollinger-Ellison syndrome and systemic mastocytosis. It is also used as maintenance therapy to keep ulcers and esophagitis from coming back after healing.

Over-the-counter products Acid Reducer and Wal-Zan tablets are specifically labeled to relieve heartburn associated with acid indigestion and sour stomach, and to prevent heartburn brought on by certain foods or beverages.
