Pu-erh Tea and Acetaminophen, Caffeine, Pyrilamine

These two interact in 2 distinct ways. Each one is explained separately below.

Why Are There 2 Interactions?

Pu-erh Tea interacts with whole categories of medication. Acetaminophen, Caffeine, Pyrilamine falls into 2 of those categories, so it can interact with Pu-erh Tea in 2 different ways. We’ve listed each one below — your overall risk is driven by the most serious of them (Moderate).

Moderate

STIMULANT DRUGS

1 of 2

Why this applies to Acetaminophen, Caffeine, Pyrilamine

Acetaminophen, Caffeine, Pyrilamine falls under STIMULANT DRUGS — the group Pu-erh Tea interacts with.

Theoretically, concomitant use might increase stimulant adverse effects.
Pu-erh tea 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 Probable Evidence C

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 explains PharmD, Clinical Pharmacist

Here's the thing to keep in mind with Midol Max Strength Menstrual: it already has caffeine built right into it. Pu-erh tea brings its own caffeine to the table too. So when you sip a cup (or several) while taking this product, you're basically stacking caffeine on top of caffeine.

That can nudge up the usual caffeine-type side effects, things like feeling jittery, a racing or pounding heart, trouble sleeping, an upset stomach, or feeling anxious or restless. This is more of a theoretical, common-sense concern based on expert opinion than a proven danger, and a single normal cup of tea is unlikely to cause trouble for most people. If you tend to be caffeine-sensitive or drink a lot of pu-erh, it's worth a quick chat with your pharmacist or doctor.

DIURETIC DRUGS

2 of 2

Acetaminophen, Caffeine, Pyrilamine also falls under DIURETIC DRUGS.

Theoretically, using pu-erh tea with diuretic drugs might increase the risk of hypokalemia.
Pu-erh tea contains caffeine. Caffeine, especially in excessive amounts, can reduce potassium levels due to stimulation of the sodium-potassium pump. Diuretics can also cause lower potassium levels.
Severity Minor 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 to know about a product like Midol Max Strength: it already contains caffeine of its own, alongside the acetaminophen (pain reliever) and pyrilamine (an antihistamine). Pu-erh tea also has caffeine. The concern on file is theoretical and rated minor, and it's really about the caffeine stacking up. Large amounts of caffeine can nudge potassium out of your bloodstream and into your cells, which can leave potassium levels a little low.

For most people having a normal cup or two of pu-erh, this isn't a big deal. But if you're drinking a lot of it on top of the caffeine in Midol, you might notice jitteriness, a racing heart, or trouble sleeping. If you take a true diuretic too, mention it to your pharmacist, since that combo is where low potassium matters more.
