Rauvolfia Vomitoria and Ibuprofen, Pseudoephedrine

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

Why Are There 2 Interactions?

Rauvolfia Vomitoria interacts with whole categories of medication. Ibuprofen, Pseudoephedrine falls into 2 of those categories, so it can interact with Rauvolfia Vomitoria in 2 different ways. We’ve listed each one below — your overall risk is driven by the most serious of them (Major).

Major

STIMULANT DRUGS

1 of 2

Why this applies to Ibuprofen, Pseudoephedrine

Ibuprofen, Pseudoephedrine falls under STIMULANT DRUGS — the group Rauvolfia Vomitoria interacts with.

Theoretically, concomitant use might cause additive effects.
Yohimbine, a constituent of Rauvolfia vomitoria, has sympathomimetic effects and increases blood pressure in a dose-dependent manner. Theoretically, taking Rauvolfia vomitoria with stimulant drugs can have additive stimulant and hypertensive effects.
Severity Major 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 explains PharmD, Clinical Pharmacist

Here's the piece to watch with this combo: it's the pseudoephedrine part of your Dristan that matters most. Pseudoephedrine is a decongestant that mildly revs up your system, which can nudge your blood pressure and heart rate up a bit. Rauvolfia vomitoria contains yohimbine-like compounds that can do the same thing, so stacking them together could push those effects higher than either alone.

In real terms, that might mean a faster or pounding heartbeat, jitteriness, trouble sleeping, headache, or a noticeable bump in blood pressure. This concern is theoretical, based on how these compounds work rather than hard studies, so don't panic. The ibuprofen piece isn't the main issue here. Still, if you take anything with rauvolfia, please check with your pharmacist or doctor first, especially if you already have high blood pressure.

ANTICOAGULANT/ANTIPLATELET DRUGS

2 of 2

Ibuprofen, Pseudoephedrine also falls under ANTICOAGULANT/ANTIPLATELET DRUGS.

Theoretically, combining Rauvolfia vomitoria with antiplatelet or anticoagulant drugs might have additive effects.
Rauvolfia vomitoria contains small amounts of yohimbine. Research in healthy adults shows that taking yohimbine in doses of 8 mg or more seems to inhibit platelet aggregation in vitro by binding to the alpha-2 adrenoceptor. The effects of Rauvolfia vomitoria itself are unclear.
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.

Here's what's going on with this combo. Your Dristan product has two active pieces: ibuprofen, which on its own can mildly thin the blood and irritate the stomach, and pseudoephedrine, a decongestant that can raise blood pressure and heart rate. Rauvolfia vomitoria contains a small amount of yohimbine, which in lab studies seemed to make platelets a little less sticky. So in theory, stacking it on top of ibuprofen might add a touch to the blood-thinning effect.

Honestly, this is a weak, theory-only concern, and the real amount of yohimbine in this plant is unclear. The bigger flag for me is that rauvolfia strongly lowers blood pressure while pseudoephedrine raises it, so they fight each other. Please run this past your pharmacist before mixing them.

About Rauvolfia Vomitoria

What is Rauvolfia Vomitoria?

  • High blood pressure
  • Anxiety and agitation
  • Sleep problems
  • Mental health symptoms (traditional use)
  • Fever and general ailments

Rauvolfia vomitoria is an African shrub whose root contains powerful alkaloids, including reserpine, that have historically been used for high blood pressure and agitation. Because these compounds can strongly affect blood pressure, mood, and the nervous system, the plant can cause serious side effects and is not a casual supplement. Always talk to a doctor or pharmacist before using it.
