What is this page for?

First and foremost: how Yoga interacts with medications. The heart of this page is the interaction list — every drug Yoga is known to interact with, and how serious each one is.

But these pages have grown well beyond that into a full monograph — what Yoga is, what people use it for and how strong the evidence is, its safety and side effects, and answers to the questions we’re asked most — written and reviewed by the clinical staff at HelloPharmacist. It’s educational information from our licensed clinical databases, not medical advice, and we don’t sell or endorse products. Our editorial policy

What Severity, Likelihood & Evidence Mean

Severity — How Serious It Can Be

Major. Clinically significant; generally best avoided, or used only under direct professional supervision.
Moderate. May need monitoring, a dose adjustment, or separating the times you take each one.
Minor. Generally not clinically significant, but still worth noting and mentioning to your pharmacist.
No known interaction. Checked against our sources with nothing documented — not the same as proven safety.

Likelihood — How Well It’s Documented

Likely. Well-controlled human studies have demonstrated the likely existence of this interaction
Probable. Interaction 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.
Possible. 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
Unlikely. Interaction has been demonstrated in animal or in lab research but has been shown not to occur in humans.

Where This Data Comes From

Interaction records are evidence-graded and sourced from the Natural Medicines database (TRC Healthcare), the same reference used by pharmacists and hospitals.

The bottom line

Overview

Yoga is not a herb or dietary supplement. It is a mind-body practice that began thousands of years ago in ancient India. The word "yoga" comes from a term meaning to join or unite, reflecting the idea of connecting the body, breath, and mind.

Modern yoga usually combines three main parts: physical postures (called asanas), breathing exercises (called pranayama), and meditation or relaxation. There are many styles, ranging from gentle and slow (such as restorative or Hatha yoga) to fast and physically demanding (such as Vinyasa or power yoga).

Today, people around the world practice yoga in studios, gyms, homes, and online. Many use it for fitness, stress relief, and overall well-being.

How it works

Yoga is thought to work through several connected pathways rather than a single active ingredient. The physical postures gently stretch and strengthen muscles, which may improve flexibility, balance, and posture.

The breathing and meditation parts may calm the body's stress response. Researchers believe yoga can help shift the nervous system toward a more relaxed state, which may lower heart rate, ease muscle tension, and reduce feelings of stress. Some studies have measured changes in stress hormones and markers of inflammation, though these findings are still being explored.

Much of this is based on smaller studies, and the exact mechanisms are not fully understood. The combination of movement, breath, and focused attention likely contributes to its overall effects.
