Interaction report

Lime and Nifedipine

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. Nifedipine 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 Nifedipine

Nifedipine 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 deal with lime and your nifedipine. This isn't about lime changing how your blood pressure pill works or how your body breaks it down. The concern is purely about your skin and sunlight. Certain medicines, including nifedipine, can make your skin a bit more sensitive to the sun, and concentrated lime oil on the skin can do the same. Put together, the worry is a slightly higher chance of sunburn or a rash on sun-exposed skin.

Honestly, this is a theoretical, lab-based concern, so don't lose sleep over it. Squeezing lime in your food or drink isn't the issue. The caution is more about applying lime essential oil to your skin and then heading into bright sun. If you use lime oil topically, rinse it off and use sunscreen, and check with your pharmacist if you have questions.

CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES

2 of 2

Nifedipine 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

Your body relies on an enzyme called CYP3A4 to clear nifedipine out of your system. Some lab and animal research suggests that plant compounds in lime juice can slow that enzyme down. If that happens, nifedipine could linger longer and build up, which may lead to stronger effects like dizziness, flushing, headache, swelling in your ankles, or blood pressure that drops lower than expected.

Here's the reassuring part: this is based only on animal studies using high doses of lime juice, so it's far from proven in people. A squeeze of lime on your food almost certainly won't be an issue. If you're thinking about concentrated lime products or lime essential oil, just check with your pharmacist or doctor first.

  • 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).

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 Nifedipine

What Is Nifedipine Used For?

Brand names: Procardia XL, Adalat PA, Adalat, Nifedin, Nifed PA, Nifed, Procardia, Adalat XL, Adalat CC, Adalat LA, Adalat Retard, Adipine MR, Adipine XL, Cardilate MR, Coracten SR, Coracten XL, Fortipine LA 40, Hypolar Retard 20, Nifedipress MR, Nifopress Retard, Tensipine MR

Nifedipine treats high blood pressure (hypertension), chronic stable angina (chest pain brought on by physical effort), and vasospastic angina (chest pain caused by spasm of the coronary arteries, sometimes called Prinzmetal's angina). Lowering blood pressure with nifedipine helps reduce the risk of strokes and heart attacks.

The capsule form is approved for vasospastic angina and chronic stable angina only — it is not approved for high blood pressure. The extended-release tablet (including Procardia) covers all three uses: vasospastic angina, chronic stable angina, and high blood pressure.
