The bottom line No known interaction

We found no known interaction between Hcg Diet and Amphetamine 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.

Hcg Diet and Amphetamine

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 Amphetamine 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 Amphetamine, 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

What Hcg Diet Itself Has Been Linked To

This is not an interaction — nothing below involves Amphetamine. It is the side-effect record for Hcg Diet on its own, from the licensed Natural Medicines monograph. If something new turns up after you add Hcg Diet, this list is the first place to look. 3 entries are worth acting on rather than waiting out — marked below.

  • Muscle weakness / Low potassium Worth acting on Additional detail

    “The HCG diet can cause refeeding syndrome. In one case report, a patient developed refeeding syndrome, including severe muscle weakness, nausea, hypophosphatemia, hypokalemia, elevated creatine kinase, and ST-segment depression with marked U waves, after taking HCG 1000 IU subcutaneous daily and restricting food consumption to less than 500 calories per day for 3 weeks.”

  • Blood clots Worth acting on Additional detail

    “The HCG diet can cause edema, thromboembolism, ascites, and pleural effusion. In a case report, a 64-year-old female presented to the emergency room with a deep venous thrombosis and a pulmonary embolism after taking 20 drops of HCG sublingually twice daily for 2 weeks. The patient was treated with anticoagulants and started on chronic warfarin therapy.”

Overlapping uses

What Amphetamine Is Prescribed For, and What Hcg Diet Has Been Studied For

These two come up together because they touch the same health topic — not because they do the same job. Amphetamine is a prescription medicine with approved uses on its FDA label. Hcg Diet is an eating pattern: what follows is what researchers have looked at it for, and how strong that evidence is.

Amphetamine is prescribed for: Amphetamine treats Attention Deficit Hyperactivity Disorder (ADHD) in patients 6 years and older. Adzenys XR-ODT, Dyanavel XR, and the amphetamine extended-release orally disintegrating tablet formulations are specifically approved for ADHD in this age group. Amphetamine Sulfate tablets and Evekeo (amphetamine sulfate tablets) are also approved for narcolepsy (a sleep disorder causing uncontrollable daytime sleepiness) and as a short-term aid in a calorie-restricted weight-loss program for exogenous obesity (weight gain from external factors like overeating) in patients who have not responded to other approaches.

Hcg Diet has been studied for:

  • Obesity studied, not established Hcg Diet has been studied for this. Natural Medicines rates the evidence: Likely Ineffective Read what the research shows

    Hcg Diet for obesity

    Clinical studies show that the HCG diet does not improve weight loss in patients with obesity.

Effectiveness ratings and the research summaries above are the verbatim record from the Natural Medicines database, which grades evidence from “Effective” down to “Insufficient Reliable Evidence To Rate”. A rating below the top of that scale means researchers have looked at it — not that it works, and never that it can stand in for a prescribed medicine. Do not stop or replace Amphetamine on your own; if you are taking Hcg Diet for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

From our pharmacist’s overview on the Amphetamine page

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.

Following Hcg Diet While Taking Amphetamine: Common Questions

Is it safe to follow Hcg Diet while taking Amphetamine?
We do not list a known interaction between Hcg Diet and Amphetamine. 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.
Are Hcg Diet and Amphetamine used for the same thing?
They overlap in purpose, which usually means the real question is whether you need both rather than whether they are safe together. This page lists the shared uses and how strong the evidence is for Hcg Diet in each. That is a conversation for your prescriber, especially if Amphetamine is being adjusted to a target.
Does Amphetamine interact with any supplements?
Yes. Amphetamine has documented interactions with 130 supplements in our database — Hcg Diet is not one of them. The Amphetamine interaction page linked on this page lists every one, ranked by severity.
