The bottom line No known interaction

We found no known interaction between Hcg Diet and Apomorphine 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 Apomorphine

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 Apomorphine 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 Apomorphine, 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 Apomorphine 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 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. One of them is worth acting on rather than waiting out — marked below.

“Apomorphine is often used as a rescue treatment for sudden "off" episodes in Parkinson's disease, which makes a reliable dose worth protecting, and this is a list to read with real care rather than skim. Of the 67 supplements and herbs on file, two carry a major rating: St.”

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 Apomorphine Injection

What Is Apomorphine Injection Used For?

Brand names: Uprima, Apokyn, APO-go, APO-go Pen, APO-go PFS

Apomorphine hydrochloride injection is used for the acute, intermittent treatment of hypomobility (reduced ability to move) during 'off' episodes in advanced Parkinson's disease. These include both 'end-of-dose wearing off' (when a dose of another Parkinson's medication stops working before the next one is due) and unpredictable 'on/off' episodes.

It is studied and used as an add-on therapy alongside other Parkinson's medications. The brands Apokyn, Apomorphine Hydrochloride injection, and Onapgo are all subcutaneous (under-the-skin) formulations approved for this use.

Following Hcg Diet While Taking Apomorphine: Common Questions

Is it safe to follow Hcg Diet while taking Apomorphine?
We do not list a known interaction between Hcg Diet and Apomorphine. 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 Apomorphine have any of the same side effects?
Yes — our sources link each of them separately to 6 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 Apomorphine interact with any supplements?
Yes. Apomorphine has documented interactions with 67 supplements in our database — Hcg Diet is not one of them. The Apomorphine interaction page linked on this page lists every one, ranked by severity.
