Drug & supplement interaction

Nickel + Terconazole

Terconazole brand name: Terazole.

No Known Interaction
The bottom line No known interaction

We found no known interaction between Nickel and Terconazole 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.

Nickel and Terconazole

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 Terconazole and Nickel 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.

How we checked

Why No Interaction Is Listed for Terconazole

Interactions in our licensed database are recorded against drug classes, not just single drug names. Terconazole is filed under 2 classifications — antifungals, oral drugs. Nickel has documented interactions with 1 drug class — the most serious being disulfiram (antabuse) (moderate) — and none of Terconazole’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.

No Interaction Found — But Data Suggests Nickel and Terconazole May Share a Side Effect

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.

  • Stomach pain Additional detail

    Nickel

    “Orally, consuming high doses of nickel 0.5-2.5 grams has been reported to cause nausea, vomiting, abdominal pain, and diarrhea. Patients with systemic nickel allergy syndrome (SNAS) can experience colic and diarrhea after consumption of nickel-rich foods.”

    Terconazole

    Listed in the ADVERSE REACTIONS section of the FDA label for Terconazole. Read the label on DailyMed ›

Reported for Nickel but not commonly for Terconazole: a severe allergic reaction, an allergic reaction, kidney problems and a skin rash.

Effects for Terconazole come from the ADVERSE REACTIONS section of its FDA label; effects for Nickel come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 805 voluntary FDA FAERS reports for Terconazole 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.

Special populations

Nickel in Pregnancy & Breastfeeding

Pregnancy And Lactation Likely Safe

When used orally and appropriately. Nickel is safe to use during pregnancy and lactation in doses below the tolerable upper intake level (UL) of 1 mg daily. There is insufficient reliable information available about the safety of nickel when taken in doses above the UL during pregnancy and lactation.

Everything else you take

See Every Supplement That Interacts With Terconazole

This page covers Nickel only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Terconazole page lists 20 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Coffee Charcoal (moderate), European Mandrake (moderate), Glucomannan (moderate) and Guar Gum (moderate).

By severity: 1 major · 7 moderate · 12 minor.

From our pharmacist’s overview on the Terconazole page

“Terconazole (Terazole) is a vaginal antifungal for yeast infections, and its supplement list earns genuine caution because of one standout: activated charcoal, the only major-rated interaction among the 20 on file. Charcoal binds many medicines and can lower their levels even when a drug is not taken by mouth, which makes it the entry…”

About Nickel

What is Nickel?

  • General trace-mineral supplementation
  • Supporting iron and other nutrient metabolism (theoretical)
  • Marketed for bone or hormone support

Nickel is a trace element found in tiny amounts in many foods, and most people get plenty through diet. There is no proven need for nickel supplements, and because nickel is a common cause of allergic reactions and can be toxic in higher amounts, most people should not take it. Talk with your pharmacist or doctor before using any nickel-containing supplement.

Trace mineral (metallic element) · Tablets, capsules, and as part of some multivitamin or trace-mineral supplements (often as nickel sulfate or nickel chloride)

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

Nickel: dosing

There is no established recommended supplement dose of nickel, because a clear human requirement has not been proven and most people get enough from food. Health authorities have set upper limits to help avoid harmful exposure, but this does not mean people need to take supplements to reach any amount.If a product contains nickel, follow the label and do not take more than directed.

About Terconazole

What Is Terconazole Used For?

Brand name: Terazole

Terconazole vaginal cream and vaginal suppositories are both indicated for the local treatment of vulvovaginal candidiasis — commonly known as a vaginal yeast infection caused by Candida species. Because these products only work against Candida, a healthcare provider should confirm the diagnosis before or during treatment.

Before starting a second course of treatment with terconazole vaginal suppositories, the diagnosis should be re-confirmed by lab tests and other possible causes of symptoms should be ruled out.

Taking Nickel and Terconazole Together: Common Questions

Is it safe to take Nickel with Terconazole?
We do not list a known interaction between Nickel and Terconazole. 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 Nickel and Terconazole have any of the same side effects?
Yes — our sources link each of them separately to one 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 Nickel and Terconazole combination checked?
Interactions in our licensed database are recorded against drug classes. Terconazole is filed under 2 classifications, and Nickel has documented interactions with 1 drug class — none of Terconazole'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 Nickel interact with any other medications?
Yes. Nickel has 1 documented drug interaction in our database — Terconazole 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 Terconazole interact with any supplements?
Yes. Terconazole has documented interactions with 20 supplements in our database — Nickel is not one of them. The Terconazole interaction page linked on this page lists every one, ranked by severity.
