Ginkgo and Triamcinolone

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

Moderate

P-GLYCOPROTEIN SUBSTRATES

Why this applies to Triamcinolone

Triamcinolone falls under P-GLYCOPROTEIN SUBSTRATES — the group Ginkgo interacts with.

Theoretically, taking ginkgo with P-glycoprotein substrates might increase the levels and adverse effects of these substrates.
A small clinical study in healthy volunteers shows that using ginkgo leaf extract 120 mg orally three times daily for 14 days can increase levels of the P-glycoprotein substrate, talinolol, by 36% in healthy male individuals. However, single doses of ginkgo do not have the same effect.
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, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the short version: triamcinolone is moved around your body partly by a transporter called P-glycoprotein. Ginkgo may slow that transporter down a bit, which could let slightly more triamcinolone hang around in your system. In theory that means a touch more steroid effect and possibly more of the usual side effects, like fluid retention, raised blood sugar, mood or sleep changes, or stomach irritation.

I'll be honest with you though, this is mostly theoretical. The evidence comes from a small study using a different drug (talinolol), and a single dose of ginkgo didn't do much at all. For occasional or short-term triamcinolone, I wouldn't lose sleep over it. Still, it's worth a quick chat with your pharmacist or doctor before you combine them, since ginkgo can also thin the blood.

About Ginkgo

What is Ginkgo?

Ginkgo
  • Memory and cognitive support
  • Age-related mental decline
  • Circulation problems
  • Tinnitus (ringing in the ears)
  • Dizziness or vertigo

Ginkgo is one of the world's most popular herbal supplements, mostly taken to support memory and circulation. The evidence for these uses is mixed and generally weak, and it is not proven to prevent memory loss or dementia. It is usually well tolerated in healthy adults, but it can thin the blood, so talk to your pharmacist or doctor before using it.

About Triamcinolone

What Is Triamcinolone Used For?

Brand names: Aristocort, Kenacort, Adcortyl Intra-articular / Intradermal, Kenalog Intra-articular / Intramuscular, Adcortyl in Orabase, Triesence

Triamcinolone is available in many forms — injections, creams, ointments, nasal sprays, dental pastes, and eye injections — each approved for specific uses. Injectable forms given into muscle are used when oral steroids aren't an option, covering severe allergies (like asthma flares, severe skin reactions, drug reactions, and serum sickness), serious skin diseases, certain endocrine (hormonal) disorders, and more.

Injections given directly into a joint (intra-articular) or soft tissue help with conditions like rheumatoid arthritis, gout flares, bursitis, and tendon inflammation. Injections into skin lesions (intralesional) treat conditions such as keloids, alopecia areata, and psoriatic plaques. Triesence (an ophthalmic injection) is specifically indicated for eye conditions like uveitis and temporal arteritis, and for visualization during eye surgery. Topical creams, ointments, lotions, and sprays relieve itching and inflammation from corticosteroid-responsive skin conditions. Dental paste forms (Oralone, Kourzeq) treat painful mouth sores from injury. Nasal sprays temporarily relieve hay fever and upper respiratory allergy symptoms such as runny nose, sneezing, and congestion.
