No Known Interaction
The bottom line No known interaction

We found no known interaction between Jaborandi and Phentermine in our sources. Absence of a documented interaction is not the same as proven safety, and does not guarantee one does not exist. Do not start, stop, or change a medication or supplement based on this page; confirm with your pharmacist or doctor first.

Jaborandi and Phentermine

We checked these two against our interaction database. Here is what we found.

No Known Interaction Found

We did not find a documented interaction between Phentermine and Jaborandi in our sources. This does not guarantee that the combination is completely free of risk — there is often limited research on supplements and herbal products, especially around drug interactions.

Worth understanding: our licensed dataset holds no drug-interaction record for Jaborandi at all — not against Phentermine, and not against any other medication we track. This verdict therefore rests on the absence of any recorded data, not on research that looked at this combination and found nothing. We cannot rule an interaction out.

If you decide to take both, the practical routine is simple: add one new thing at a time and note the date you started it. If the combination is going to disagree with you, it usually shows in the first days to a couple of weeks — and a start date turns “I’ve been feeling off” into something a pharmacist can actually work with. Do not stop a prescribed medicine on your own.

Always talk with your pharmacist or doctor before making changes to your medications or supplements, particularly if you take several medications or have an ongoing health condition.

What Jaborandi Itself Has Been Linked To

This is not an interaction — nothing below involves Phentermine. It is the side-effect record for Jaborandi on its own, from the licensed Natural Medicines monograph. If something new turns up after you add Jaborandi, this list is the first place to look. 3 entries are worth acting on rather than waiting out — marked below.

  • A slow heartbeat Worth acting on Additional detail

    “Orally, jaborandi can cause toxicity. Symptoms of jaborandi poisoning include bradycardia, bronchospasm, colic, cardiac collapse and possible arrest, convulsions, hypotension, dyspnea, nausea, severe salivation, strong secretion of sweat, and vomiting. The lethal oral dose of jaborandi leaf is approximately 5-10 grams (18).”

Everything above comes from the Natural Medicines adverse-effect record for Jaborandi — expand a row for the licensed statement it rests on. We read the ADVERSE REACTIONS section of Phentermine’s FDA label too, and the two lists don’t meaningfully overlap — which is why no Phentermine column appears here.

See Every Supplement That Interacts With Phentermine

This page covers Jaborandi only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Phentermine page lists 61 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Ephedra (major), Peyote (major), Rauvolfia Vomitoria (major) and Sida Cordifolia (major).

By severity: 5 major · 43 moderate · 13 minor.

From our pharmacist’s overview on the Phentermine page

“Ephedra is the pairing I most want anyone taking phentermine (Adipex-P) to know about. Phentermine is itself a stimulant appetite suppressant that raises heart rate and blood pressure, and ephedra piles the same cardiovascular strain on top of it.”

About Jaborandi

What is Jaborandi?

  • Dry mouth (xerostomia)
  • Glaucoma and high eye pressure
  • Promoting sweating
  • Increasing saliva production
  • Traditional remedy for various ailments

Jaborandi is a South American plant best known as the natural source of pilocarpine, a drug used in modern medicine for glaucoma and dry mouth. The raw herb is potent and potentially toxic, so it is not something to use casually as a home remedy. If you need its effects, use the FDA-approved pilocarpine products prescribed by your doctor rather than the crude plant.

Pilocarpus microphyllus · Rutaceae · Leaves · Standardized pharmaceutical extract (pilocarpine), eye drops, tablets, and historically as a tea or tincture

An interaction check asks whether these two react with each other — it does not ask whether Jaborandi is a good idea for someone in your situation. Here is what our Jaborandi record says about it on its own.

Jaborandi: dosing

There is no established safe dose for the crude Jaborandi herb, and we do not recommend self-dosing with the raw plant because its potency is unpredictable and it can be toxic.The purified drug pilocarpine is a different story — it comes in carefully measured tablets and eye drops with doses set by a doctor.

About Phentermine

What Is Phentermine Used For?

Brand names: Adipex-P, Fastin, T Diet, Phentride, Obenix, Pbc Phentride, Pbw Phentride, Phentrol #3, Ionamin, Phentrol #6, Phentrol #2, Phentrol #5, Phentrol, Obermine, Phentermine, Suprenza

Phentermine is approved as a short-term addition to a weight-loss program — not a standalone treatment. It is used alongside reduced-calorie eating, increased physical activity, and behavior changes to help manage obesity in adults whose body mass index (BMI) is 30 kg/m² or higher, or 27 kg/m² or higher when other risk factors such as controlled high blood pressure, diabetes, or high cholesterol (hyperlipidemia) are also present.

All available phentermine products — including Adipex-P, Lomaira, and various generic capsules and tablets — share this same FDA-approved use. Lomaira tablets are specifically dosed to be taken three times daily before meals, while other formulations are generally taken once daily. Treatment is intended to last only a few weeks.
