7-alpha-hydroxy-dhea + Phentermine
Phentermine brand names: Adipex-P, Fastin, T Diet, Phentride, Obenix, and others.
We found no known interaction between 7-alpha-hydroxy-dhea and Phentermine 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.
7-alpha-hydroxy-dhea and Phentermine
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 Phentermine and 7-alpha-hydroxy-dhea 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.
Worth understanding: our licensed dataset holds no drug-interaction record for 7-alpha-hydroxy-dhea at all — not against Phentermine, 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.
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.

What Phentermine Is Prescribed For, and What 7-alpha-hydroxy-dhea Has Been Studied For
These two come up together because they touch the same health topic — not because they do the same job. Phentermine is a prescription medicine with approved uses on its FDA label. 7-alpha-hydroxy-dhea is a supplement: what follows is what researchers have looked at it for, and how strong that evidence is.
Phentermine is prescribed for: Phentermine is approved as a short-term addition to a weight-loss program — not a standalone treatment. It is used alongside reduced-calorie eating, increased physical activity, and behavior changes to help manage obesity in adults whose body mass index (BMI) is 30 kg/m² or higher, or 27 kg/m² or higher when other risk factors such as controlled high blood pressure, diabetes, or high cholesterol (hyperlipidemia) are also present. All available phentermine products — including Adipex-P, Lomaira, and various generic capsules and tablets — share this same FDA-approved use. Lomaira tablets are specifically dosed to be taken three times daily before meals, while other formulations are generally taken once daily.

Obesity studied, not established 7-alpha-hydroxy-dhea has been studied for this. Natural Medicines rates the evidence: Insufficient Reliable Evidence To Rate Read what the research shows
7-alpha-hydroxy-dhea for obesity
Although there has been interest in using oral 7-alpha-hydroxy-DHEA for obesity, there is insufficient reliable information about the clinical effects of 7-alpha-hydroxy-DHEA for this purpose.
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 Phentermine on your own; if you are taking 7-alpha-hydroxy-dhea for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

See Every Supplement That Interacts With Phentermine
This page covers 7-alpha-hydroxy-dhea only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Phentermine page lists 61 supplements it has a documented interaction with, worst first, each one explained.
The most serious there right now: Activated Charcoal (major), Ephedra (major), Peyote (major), Rauvolfia Vomitoria (major) and Sida Cordifolia (major).
By severity: 5 major · 43 moderate · 13 minor.
From our pharmacist’s overview on the Phentermine page
“Ephedra is the pairing I most want anyone taking phentermine (Adipex-P) to know about. Phentermine is itself a stimulant appetite suppressant that raises heart rate and blood pressure, and ephedra piles the same cardiovascular strain on top of it.”

Where does our data come from?
- Source: the Natural Medicines (TRC Healthcare) clinical database — the evidence-graded professional reference for herb & supplement interactions. 7-alpha-hydroxy-dhea is not yet covered by that licensed database, so its write-up cites publicly available medical sources directly (see the references below).
- Citation library: 103,510 references behind our interaction content, 65,311 of them resolved to verified PubMed/DOI sources. See every 7-alpha-hydroxy-dhea reference on this page ↓
- Freshness: we automatically re-check this combination every week — this pair was last verified September 20, 2026. The 7-alpha-hydroxy-dhea and Phentermine records this page draws on were last updated June 22, 2026.
- What “no known interaction” means: no documented interaction in the sources above — not a guarantee of safety. Supplements are studied far less than prescription drugs, so we say exactly what the evidence supports, and nothing more.
About 7-alpha-hydroxy-dhea
What is 7-alpha-hydroxy-dhea?
- Anti-aging support
- Immune support
- Weight management
- Energy and vitality
- Hormone metabolism support
7-alpha-hydroxy-DHEA is a natural breakdown product (metabolite) of the adrenal hormone DHEA, and very little reliable human research exists on taking it as a supplement. Because it is hormone-related and poorly studied, the safest approach is to avoid it unless a knowledgeable doctor or pharmacist advises otherwise.
Not a plant; this is a hormone metabolite (made in the body or made synthetically for supplements) · Capsules, tablets, sublingual products (often marketed as part of DHEA-related supplements)
An interaction check asks whether these two react with each other — it does not ask whether 7-alpha-hydroxy-dhea is a good idea for someone in your situation. Here is what our 7-alpha-hydroxy-dhea record says about it on its own.
7-alpha-hydroxy-dhea: dosing
There is no established or standardized dose for 7-alpha-hydroxy-DHEA. Reliable studies that would tell us a safe and effective amount are lacking.If a product is used, follow the directions on the label and do not exceed them.
