Interaction report

Lime and Voriconazole

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

Why Are There 2 Interactions?

Lime interacts with whole categories of medication. Voriconazole falls into 2 of those categories, so it can interact with Lime 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 Voriconazole

Voriconazole falls under PHOTOSENSITIZING DRUGS — the group Lime interacts with.

Theoretically, concomitant use of lime oil with photosensitizing drugs may increase the risk of phototoxicity.
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.

Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the thing with voriconazole (Vfend): it can already make your skin much more sensitive to sunlight. People on it often sunburn faster than usual, and long-term use has been tied to skin reactions. Lime oil applied to the skin contains compounds (like furanocoumarins and limonene) that can also react with sunlight, so in theory the two together could add up to a higher chance of burns, redness, or blistering on sun-exposed skin.

I want to be honest that this concern comes only from lab and animal data, so it's theoretical, not proven in people. Eating or drinking lime as a food is very unlikely to matter. The bigger caution is concentrated lime essential oil on your skin plus sun. Either way, good sun protection is smart while on voriconazole. Check with your pharmacist if you're unsure.

CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES

2 of 2

Voriconazole also falls under CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES.

Animal research shows that phenolics in lime juice inhibit cytochrome P450 3A4. This has been demonstrated in rats treated with sildenafil, a CYP3A4 substrate, and high doses of lime juice.
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.

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the gist: your body clears voriconazole partly through a liver enzyme called CYP3A4. Lab and animal studies suggest that certain plant compounds in lime juice can slow that enzyme down a bit. If the enzyme works slower, voriconazole could hang around longer than expected, which in theory might nudge up its levels and side effects like visual changes (blurry or bright vision), nausea, headache, or liver strain.

The important part is that this signal comes only from animal and test-tube research, not from people, so I wouldn't lose sleep over a squeeze of lime in your food or a drink. Concentrated lime supplements or large amounts of juice are a different story. Voriconazole is a finicky drug with a narrow safety window, so before using anything lime-based for health reasons, just run it by your pharmacist or doctor.

Severity how clinically significant the interaction is
Major

Clinically significant. Avoid the combination, or use only under close professional supervision.

Moderate

Usually worth avoiding or managing — may need monitoring, a dose change, or timing apart.

Minor

Generally not serious. Be aware of it and mention it to your pharmacist.

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.

About Lime

What is Lime?

Lime
  • Source of vitamin C
  • Digestive upset
  • Skin care
  • Mood and aromatherapy
  • Flavoring and food preservation

Lime is a common citrus fruit and a good natural source of vitamin C and plant antioxidants. As a food it is generally safe and enjoyed by most people, but evidence that lime treats any specific health condition is limited. Use the essential oil with care, and check with your pharmacist or doctor before using concentrated lime products for health reasons.

About Voriconazole

What Is Voriconazole Used For?

Brand name: Vfend

Voriconazole treats several serious fungal infections. Across all available forms — tablets, oral suspension, and intravenous (IV) injection — it is used for invasive aspergillosis (a dangerous mold infection), candidemia (Candida fungus in the bloodstream) in patients who are not neutropenic (not severely low on white blood cells), other deep-tissue Candida infections, and serious infections caused by Scedosporium apiospermum or Fusarium species in patients who cannot tolerate or have not responded to other antifungal treatments.

Esophageal candidiasis (a Candida infection of the esophagus, the swallowing tube) is also an approved use for most formulations. Note on the oral tablet form (generic voriconazole tablets): that specific tablet formulation is approved for patients aged 12 to 14 years weighing at least 50 kg, and all patients 15 years and older — not for younger or smaller children. The oral suspension and the IV injection are approved for patients 2 years and older for most of these conditions.
