Interaction report

Khella and Amiodarone

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

Why Are There 2 Interactions?

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

Moderate

PHOTOSENSITIZING DRUGS

1 of 2

Why this applies to Amiodarone

Amiodarone falls under PHOTOSENSITIZING DRUGS — the group Khella interacts with.

Theoretically, concomitant use might result in increased photosensitivity. Khella constituents can cause photosensitivity. Some drugs that cause photosensitivity include amitriptyline (Elavil), quinolones (Ciprofloxacin, others), sulfa drugs (Septra, Bactrim, others), and tetracycline.
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.

Here's the thing to know about this combo: it's really about your skin, not your heart rhythm. Amiodarone is well known for making your skin much more sensitive to sunlight, and it can even give your skin a bluish-gray tint with long-term use. Khella contains compounds (like khellin) that can also trigger sun sensitivity. Put the two together and you could sunburn faster or react more strongly to UV light than you'd expect.

I'll be straight with you, this is a theoretical concern based mostly on anecdotal reports, not strong studies. Khella won't change how amiodarone works on your heart. Still, since amiodarone alone already makes you sun-sensitive, it makes sense to use good sunscreen and cover up. Run any khella use past your pharmacist or doctor first.

HEPATOTOXIC DRUGS

2 of 2

Amiodarone also falls under HEPATOTOXIC DRUGS.

Theoretically, khella might have additive adverse effects on the liver when used with hepatotoxic drugs. Khella can increase liver transaminases. Some drugs that can adversely affect the liver include acetaminophen (Tylenol), amiodarone (Cordarone), carbamazepine (Tegretol), isoniazid (INH), methotrexate (Rheumatrex), methyldopa (Aldomet), and many others.
Severity Moderate Likelihood Possible Evidence B

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 amiodarone: it's well known for being tough on the liver. Even on its own, your doctor checks your liver enzymes regularly while you're taking it. Khella can raise those same liver enzymes, so the concern is that pairing the two could add up and stress your liver more than either would alone.

This is a theoretical concern based on limited evidence, not something proven to happen often, so I don't want you to panic. Still, with a drug like amiodarone that already carries liver risk, I'd play it safe. Watch for things like yellowing skin or eyes, dark urine, belly pain, or unusual tiredness, and please check with your pharmacist or doctor before adding khella.

Likelihood how strong the evidence is that the interaction actually happens in people
  • LikelyWell-controlled human studies have demonstrated the likely existence of this interaction.
  • ProbableInteraction 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.
  • PossibleInteraction 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.
  • UnlikelyInteraction has been demonstrated in animal or in lab research but has been shown not to occur in humans.
Evidence the quality of the studies behind the rating (graded A–D)
  • AHigh-quality meta-analysis (quantitative systematic review).
  • BCase-control study.
  • CConsensus.

From our pharmacist’s overview on the Amiodarone page

“Amiodarone (Pacerone, Cordarone) treats dangerous heart rhythms, and this is one supplement list I would genuinely be careful with. Of the 210 ingredients on file, 11 carry a major rating, and the everyday one is grapefruit, which blocks the liver enzyme that clears amiodarone and can push the drug's level higher than intended.”

Khella is a Mediterranean herb whose seeds contain compounds like khellin that may relax smooth muscle in the airways and blood vessels. While it has a long history of traditional use for breathing and heart problems, modern evidence in supplement form is limited, and it can cause side effects and sun sensitivity, so talk with your pharmacist or doctor before using it.

About Amiodarone

What Is Amiodarone Used For?

Brand names: Pacerone, Cordarone

Amiodarone is prescribed for adults with serious, life-threatening heart-rhythm problems that haven't responded to other medications. Specifically, it's used for two dangerous arrhythmias (abnormal heartbeats): recurrent ventricular fibrillation (a chaotic, potentially fatal heart rhythm) and recurrent ventricular tachycardia (a dangerously fast heart rhythm that causes unstable blood pressure).

Because amiodarone comes with significant risks, doctors reserve it for situations where other options haven't worked or can't be tolerated. It is not a first-choice medication — it's a last-resort tool for serious, life-threatening conditions.
