Guarana and Acetaminophen, Pseudoephedrine, Triprolidine

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

Moderate

STIMULANT DRUGS

Why this applies to Acetaminophen, Pseudoephedrine, Triprolidine

Acetaminophen, Pseudoephedrine, Triprolidine falls under STIMULANT DRUGS — the group Guarana interacts with.

Theoretically, concomitant use might increase stimulant adverse effects.
Guarana contains caffeine. Due to the central nervous system (CNS) stimulant effects of caffeine, concomitant use with stimulant drugs can increase the risk of adverse effects.
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 thing about Actifed Plus ES: one of its three ingredients, pseudoephedrine, is already a stimulant decongestant. Guarana is basically concentrated caffeine, so taking the two together stacks one stimulant on top of another. The concern isn't your liver or how the drug is broken down, it's simply the combined revved-up effect.

In real life that could mean a faster or pounding heartbeat, jitteriness, trouble sleeping, anxiety, or a bump in blood pressure. None of this is guaranteed, and this caution is mostly theoretical based on how caffeine and decongestants behave. Still, if you have heart issues or anxiety, it's worth a quick chat with your pharmacist before pairing them, especially with strong guarana supplements rather than a small amount in food.

From our pharmacist’s overview on the Acetaminophen, Pseudoephedrine, Triprolidine page

“Actifed Plus ES combines acetaminophen, pseudoephedrine, and triprolidine, and the pseudoephedrine is why I would check this page carefully before adding any supplement. Stimulation dominates the list: 44 ingredients, from ephedra to the everyday caffeine in coffee, tea, and cocoa, can stack on the decongestant and push blood pressure…”

About Guarana

What is Guarana?

Guarana
  • Energy and alertness
  • Reducing fatigue
  • Weight loss support
  • Athletic performance
  • Mental focus

Guarana is an Amazonian seed that is naturally high in caffeine, which explains most of its stimulant and energy effects. While it may give a short-term boost in alertness and reduce fatigue, strong evidence for weight loss or major performance gains is limited, and it carries the same risks as too much caffeine. Talk to your pharmacist or doctor before using it, especially if you have heart problems, anxiety, or are pregnant.
