Yerba Mate and Terbutaline

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

Moderate

BETA-ADRENERGIC AGONISTS

Why this applies to Terbutaline

Terbutaline falls under BETA-ADRENERGIC AGONISTS — the group Yerba Mate interacts with.

Theoretically, the caffeine in yerba mate might increase the cardiac inotropic effects of beta-agonists, especially if taken in large amounts.
Yerba mate contains caffeine. Caffeine can increase cardiac inotropic effects of beta-agonists.
Severity Moderate Likelihood Probable Evidence D

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..

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the simple version. Terbutaline is a beta-agonist, meaning it relaxes your airways but can also rev up your heart a bit. Yerba mate carries caffeine, which is a stimulant in its own right. Put the two together and the concern is that they could nudge your heart in the same direction, leading to a faster or more pounding heartbeat, the jittery or shaky feeling, and sometimes a sense of being wound up or anxious.

I want to be honest about the strength of this one. It's mostly theoretical, based on how these things work rather than firm studies, and it matters more with larger amounts of mate. A casual cup is unlikely to cause trouble. If you drink mate regularly or notice extra jitters or palpitations, just mention it to your pharmacist or doctor.

About Yerba Mate

What is Yerba Mate?

Yerba Mate
  • Energy and alertness
  • Weight loss
  • Mental focus
  • Digestive support
  • Antioxidant support

Yerba mate is a caffeine-containing herbal beverage from South America that is widely enjoyed for its stimulating, coffee-like effects. While it is rich in antioxidants and is being studied for weight, blood sugar, and cholesterol, strong human evidence for most health claims is limited. Drinking very hot mate over many years has been linked to higher risk of certain cancers, so enjoy it warm and in moderation.

About Terbutaline

What Is Terbutaline Used For?

Brand names: Bricanyl, Brethine, Bricanyl Injection, Bricanyl Turbohaler

Terbutaline Sulfate — available as both a tablet and a subcutaneous (under-the-skin) injection — is used to prevent and reverse bronchospasm (sudden tightening of the airways) in adults and children 12 years and older. It is indicated for people with asthma and for reversible bronchospasm associated with bronchitis and emphysema.

Both Terbutaline Sulfate Tablets and Terbutaline Sulfate Injection share these approved uses. The injection form acts more quickly and is given by a healthcare provider under the skin, while the tablet form is taken by mouth on a regular schedule during waking hours.
