Jambolan and Phenelzine Sulfate

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 Phenelzine Sulfate and Jambolan 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.

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.

Jambolan safety at a glance

Jambolan overall Use caution The fruit is widely eaten as food, but concentrated supplement doses are not well studied.

How we checked

Why No Interaction Is Listed for Phenelzine Sulfate

Interactions in our licensed database are recorded against drug classes, not just single drug names. Phenelzine Sulfate is filed under 6 classifications — including monoamine oxidase inhibitors (maois), antidepressant drugs, serotonergic drugs. Jambolan has documented interactions with 3 drug classes — the most serious being antidiabetes drugs (moderate), cytochrome p450 2c9 (cyp2c9) substrates (moderate) and sitagliptin (januvia) (minor) — and none of Phenelzine Sulfate’s classifications are among them.

Classification data comes from our licensed Natural Medicines dataset. A medication can belong to classes beyond those recorded there, so this describes how the check was run — it is not a safety guarantee.

About Jambolan

What is Jambolan?

  • Blood sugar support
  • Digestive upset and diarrhea
  • Sore throat and mouth health
  • Antimicrobial
  • General antioxidant support

Jambolan (Syzygium cumini), also called Java plum or black plum, is a tropical fruit tree traditionally used for blood sugar and digestive complaints. Human evidence for these uses is limited and not strong, so it should not replace proven treatments like diabetes medication. The fruit is safe as food, but talk to your pharmacist or doctor before using concentrated supplements.

Syzygium cumini · Myrtaceae · Seeds, fruit, leaves, and bark · Dried seed powder, capsules, tea, fruit extract, juice

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

Jambolan: dosing

There is no well-established standardized dose for Jambolan supplements. Traditional use and products vary widely in the part used (seed, fruit, leaf, or bark) and in how concentrated they are.Because a proven safe and effective dose has not been set, the best approach is to follow the directions on the product label and not exceed them.

About Phenelzine

What Is Phenelzine Used For?

Brand name: Nardil

Phenelzine treats depression in people described as “atypical,” “nonendogenous,” or “neurotic.” These patients often have a mix of anxiety and depression, along with phobic or hypochondriacal features (intense fears or excessive worry about health).

It is rarely the first antidepressant tried. It is more suitable for people who did not respond to the drugs more commonly used. Evidence is less conclusive for severe depression with endogenous features. These uses apply to Phenelzine Sulfate tablets and Nardil tablets.

Most-Reported Side Effects for Phenelzine Sulfate

From FAERS, the FDA’s public side-effect reporting system (0 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Depression 187 reports
