Phentermine
Bottom line
Phentermine is sold here as a generic under its own name. Phentermine is also one of the active ingredients in Qsymia (phentermine and topiramate) — a combination with its own label, trial and price, so none of its figures are counted here. Every figure below carries its source and the date it was read.
No clinician has reviewed this page. Label and trial statements are quoted from the FDA label or the trial cited beside them. General guidance is marked as such, and every price carries the date it was verified. That is sourcing, not medical review. What we do and do not check · Who checked the price
What is phentermine, and what does it cost?
Phentermine is sold as a generic under its own name. Phentermine is also one of the active ingredients in Qsymia (phentermine and topiramate) — a combination with its own label, trial and price, so none of its figures are counted here. Its FDA label lists constipation, diarrhea, dizziness, headache, insomnia and dry mouth among the common reactions, each with its own page here. A compounded preparation of the same molecule is a different legal product rather than a discount on the approved one: compounding is an exemption from approval, so it carries no trial and no approved label of its own.
Where can I buy phentermine?

Phentermine, answered
- What is the cheapest phentermine?
- No verified all-in price is published for any route to phentermine on this site, which is a fact about the sellers rather than a gap here.
- Which products contain phentermine?
- Phentermine, sold as a generic under its own name. Phentermine is also one of the active ingredients in Qsymia (phentermine and topiramate) — a combination with its own label, trial and price, so none of its figures are counted here.
- Is compounded phentermine the same as the branded version?
- Same molecule, different legal product. Compounding is an exemption from FDA approval rather than a form of it, so a compounded preparation has no trial and no approved label of its own, and its quality is a fact about the pharmacy that mixes it. No seller on this site names that pharmacy — all eleven checked, with the pages read listed at /pharmacy.
Every price carries its source and the date it was read; anything past 45 days without a re-check is marked stale rather than quietly aging. Label information from FDA prescribing information for phentermine hydrochloride tablets (Aurolife Pharma). Information only, not medical advice.
