Drug & supplement interaction

Hcg Diet + Terconazole

Terconazole brand name: Terazole.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 20, 2026
The bottom line No known interaction

We found no known interaction between Hcg Diet 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.

Interaction report

Hcg Diet 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 Hcg Diet in our sources. This does not guarantee that the combination is completely free of risk — research on Hcg Diet alongside specific medications may be limited.

Worth understanding: our licensed dataset holds no drug-interaction record for Hcg Diet at all — not against Terconazole, and not against any other medication we track. This verdict therefore rests on the absence of any recorded data, not on research that looked at this combination and found nothing. We cannot rule an interaction out.

Hcg Diet is an eating pattern rather than something you take. Ask your pharmacist or doctor before changing how you eat while on a prescribed medicine: some medicines are dosed around meals, and a change in diet can change how they work. 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.

What to actually watch for

No Interaction Found — But Data Suggests Hcg Diet 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 following Hcg Diet while taking the medicine can make those effects more likely to turn up, and harder to pin on one or the other if they do.

    Terconazole

    Listed in the ADVERSE REACTIONS section of the FDA label for Terconazole, and in voluntary FDA adverse-event reports. Read the label on DailyMed ›

Reported for Hcg Diet but not commonly for Terconazole: blood clots, muscle weakness, anxiety or restlessness and mood changes or irritability.

Effects for Terconazole come from the ADVERSE REACTIONS section of its FDA label; effects for Hcg Diet 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.

See Every Supplement That Interacts With Terconazole

This page covers Hcg Diet 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 Hcg Diet

What is Hcg Diet?

  • Rapid weight loss
  • Appetite control during dieting
  • Body fat reduction

The HCG diet pairs a very low-calorie diet (often around 500 calories a day) with human chorionic gonadotropin, a pregnancy hormone, and claims to cause fast, targeted fat loss. There is no good scientific evidence that hCG helps with weight loss or hunger, and the FDA has not approved it for this use; any weight lost comes from the extreme calorie restriction, which can be dangerous. Talk to your doctor or pharmacist before trying any HCG product.

Human chorionic gonadotropin (hCG) hormone, used with a very low-calorie diet · Injections, sublingual (under-the-tongue) drops, oral pellets, sprays

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

Hcg Diet: dosing

There is no safe or approved dose of hCG for weight loss. Because the FDA has not approved this use, no reliable dosing exists, and over-the-counter products are not standardized or proven.We do not recommend the HCG diet. Never start a very low-calorie diet or use hormone products on your own.

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.

Following Hcg Diet While Taking Terconazole: Common Questions

Is it safe to follow Hcg Diet while taking Terconazole?
We do not list a known interaction between Hcg Diet 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 Hcg Diet 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.
Does Terconazole interact with any supplements?
Yes. Terconazole has documented interactions with 20 supplements in our database — Hcg Diet is not one of them. The Terconazole interaction page linked on this page lists every one, ranked by severity.
