African Wild Potato and Acetaminophen, Pseudoephedrine, Triprolidine

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

Moderate

CYTOCHROME P450 1A2 (CYP1A2) SUBSTRATES

Why this applies to Acetaminophen, Pseudoephedrine, Triprolidine

Acetaminophen, Pseudoephedrine, Triprolidine falls under CYTOCHROME P450 1A2 (CYP1A2) SUBSTRATES — the group African Wild Potato interacts with.

In vitro research shows that African wild potato extract inhibits cytochrome P450 1A2 (CYP1A2). However, this effect has yet to be reported in humans. Until more is known, use with caution. Theoretically, concomitant use of African wild potato with CYP1A2 substrates might increase the risk for adverse effects from these substrates. Some of these drugs include amitriptyline (Elavil), haloperidol (Haldol), ondansetron (Zofran), propranolol (Inderal), theophylline (Theo-Dur, others), verapamil (Calan, Isoptin, others), and others.
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

Let's break down what we're really looking at here. The concern is that, in test-tube studies only, African Wild Potato may slow down a liver enzyme called CYP1A2. If that happened in real people, drugs cleared by that enzyme could build up a bit and cause stronger side effects. The good news is this product (Actifed Plus ES) is a combo of acetaminophen, pseudoephedrine, and triprolidine, and none of those three lean heavily on CYP1A2 for their breakdown, so a meaningful interaction is unlikely.

I'd still keep an eye out for the usual culprits with this medicine: feeling jittery or wired, a racing heart, or trouble sleeping from the pseudoephedrine, and drowsiness from the triprolidine. Since this is only lab data, there's no need to panic, but it's always worth a quick chat with your pharmacist before combining them.

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…”
