Lime + Guselkumab

Guselkumab brand name: Tremfya.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 13, 2026
The bottom line No known interaction

We found no known interaction between Lime and Guselkumab 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. Additionally, although there is no interaction, the two are separately associated with some of the same side effects, which would make a new symptom harder to attribute to one or the other.

Lime and Guselkumab

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 Guselkumab and Lime 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.

Lime safety at a glance

Lime overall Generally safe Lime is safe for most people when used as a normal food or drink.
Pregnancy Use caution Lime as food is generally fine, but concentrated extracts or essential oil should be avoided unless cleared by your doctor.
Breastfeeding Use caution Lime in food amounts is likely fine, but safety of concentrated products is not well studied.

Safety guidance is general; always confirm with your pharmacist or doctor for your situation.

How we checked

Why No Interaction Is Listed for Guselkumab

Interactions in our licensed database are recorded against drug classes, not just single drug names. Guselkumab is filed under a single classification — immunosuppressants. Lime has documented interactions with 2 drug classes — the most serious being cytochrome p450 3a4 (cyp3a4) substrates (moderate) and photosensitizing drugs (moderate) — and none of Guselkumab’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.

What to actually watch for

No Interaction Found — But Data Suggests Lime and Guselkumab May Share Several of the Same Side Effects

This is not an interaction. Neither one changes how your body handles the other, and nothing here says they react together. What our sources do show is that each has separately been linked to the effects below — so taking both can make those effects more likely to turn up, and harder to pin on one or the other if they do. One of them is worth acting on rather than waiting out — marked below.

  • Bleeding or bruising Worth acting on Additional detail

    Lime

    “Orally, lime juice may cause diarrhea or tooth sensitivity and wear, but these adverse effects are rare.

    Topically, lime oil and lime juice can cause allergic contact dermatitis (12,4058,100122,100132). Phytophotodermatitis is common when topical exposure to lime is followed by exposure to the sun.

    Intravaginally, 20% to 100% lime juice can cause burning, dryness, pain, itching, erythema, edema, or abnormal bleeding.”

    “Intravaginally, 20% lime juice has resulted in burning, dryness, erythema, and edema. Higher doses of 25%, 50%, or 100% lime juice were dose-dependently related to vaginal, cervical, or vulval symptoms, especially pain, itching, and abnormal bleeding. The abnormal bleeding was most common in women that had applied 100% lime juice with a tampon. Peeling, erythema, discharge, and tenderness also occurred.”

Effects for Guselkumab come from the ADVERSE REACTIONS section of its FDA label; effects for Lime come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 35,559 voluntary FDA FAERS reports for Guselkumab that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Wording is matched across sources by our own clinical vocabulary, so treat this as a prompt to pay attention, not a diagnosis.

See Every Supplement That Interacts With Guselkumab

This page covers Lime only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Guselkumab page lists 53 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Active Hexose Correlated Compound (ahcc) (moderate), Alfalfa (moderate), American Ginseng (moderate), Andrographis (moderate) and Ashwagandha (moderate).

By severity: 52 moderate · 1 minor.

From our pharmacist’s overview on the Guselkumab page

“Guselkumab (Tremfya) quiets an overactive branch of the immune system to control psoriasis and psoriatic arthritis, and all 53 supplements on this list interact the same way, by potentially revving that system back up. None is rated major, 52 are moderate and one is minor, so for most people this reads as a watch list rather than a sto…”

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.

Citrus aurantifolia · Rutaceae · Fruit, juice, peel, and essential oil · Fresh fruit, juice, essential oil, zest/peel, extracts

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

Lime: dosing

There is no standardized medicinal dose of lime. As a food, people use lime juice, zest, or wedges freely to taste.

About Guselkumab Injection

What Is Guselkumab Injection Used For?

Brand name: Tremfya

Tremfya (guselkumab) injection is approved to treat adults and children 6 years of age and older who weigh at least 40 kg (about 88 lbs) with moderate-to-severe plaque psoriasis or active psoriatic arthritis. It is also approved for adults with moderately to severely active ulcerative colitis or Crohn's disease.

For plaque psoriasis and psoriatic arthritis, Tremfya is an option when systemic therapy or phototherapy is appropriate. For ulcerative colitis and Crohn's disease, Tremfya is approved for adult patients only — it has not been established as safe and effective for children with those conditions.

Most-Reported Side Effects for Guselkumab

From FAERS, the FDA’s public side-effect reporting system (35,559 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Taking Lime and Guselkumab Together: Common Questions

Is it safe to take Lime with Guselkumab?
We do not list a known interaction between Lime and Guselkumab. That does not guarantee the combination is risk-free, so confirm with your pharmacist or doctor — especially if you take other medications or have a health condition.
Do Lime and Guselkumab have any of the same side effects?
Yes — our sources link each of them separately to 5 of the same effects. That is not an interaction: neither changes how your body handles the other. It does mean that if one of those effects turns up, it can be harder to tell which one is behind it. They are listed on this page with the source behind each.
How was the Lime and Guselkumab combination checked?
Interactions in our licensed database are recorded against drug classes. Guselkumab is filed under 1 classification, and Lime has documented interactions with 2 drug classes — none of Guselkumab's classifications are among them. A medication can belong to classes beyond those recorded in our dataset, so this describes how the check was run rather than guaranteeing safety.
Does Lime interact with any other medications?
Yes. Lime has 886 documented drug interactions in our database — Guselkumab is simply not one of them. If you take anything else, it is worth checking each one; they are all listed on this page.
Does Guselkumab interact with any supplements?
Yes. Guselkumab has documented interactions with 53 supplements in our database — Lime is not one of them. The Guselkumab interaction page linked on this page lists every one, ranked by severity.
