Yerba Mate and Gestodene

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

Minor

CONTRACEPTIVE DRUGS

Why this applies to Gestodene

Gestodene falls under CONTRACEPTIVE DRUGS — the group Yerba Mate interacts with.

Theoretically, contraceptive drugs might increase the levels and adverse effects of the caffeine contained in yerba mate.
Yerba mate contains caffeine. Contraceptive drugs decrease the rate of caffeine clearance by 40% to 65%.
Severity Minor 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 gist for Gestodene (in Minesse), which is a birth control pill. The interesting thing is that the pill is not the one that builds up here. Instead, the hormones in your birth control slow down how fast your body clears caffeine, and yerba mate is loaded with caffeine. Studies suggest caffeine clearance can drop by roughly 40 to 65 percent, so the caffeine sticks around longer.

In plain terms, your usual mate may hit harder than expected. You might notice more jitters, a racing heart, trouble sleeping, or feeling wired. This is rated minor and is really about the caffeine, not your contraception working less well. If mate leaves you buzzy, just ease back on the amount, and check with your pharmacist or doctor if you have questions.

From our pharmacist’s overview on the Gestodene page

“Gestodene, the progestin in the low-dose birth control pill Minesse, is a medication where a weakened dose has a real consequence: unintended pregnancy. So the 59 supplements and herbs on file deserve genuine vigilance, and the two rated major most of all.”

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.
