What Is the Difference Between Phentermine & Phentarmine?

Phentermine is a popular and very effective diet drug, but it can be tricky to spell, particularly if you have only heard of it from your friends and never seen it written in an authoritative place. Unscrupulous Internet retailers take advantage of this fact by capitalizing on common misspellings such as phentarmine, fentermine, phentremine, etc.

Phentermine Facts

• The diet drug phentermine has been around since the late 1950s, and is still one of the most popular diet drugs available, because of its efficacy, low price, and long history. Phentermine and phentermine hydrochloride, or phentermine HCL, are the only technically correct names for this drug. It is currently sold under the trade names Ionamin and Adipex-P, as well as in generic form.

Phentermine Fakes

• With the advent of Internet search technology and online pharmacies, many people seek to purchase phentermine online. Buying phentermine online can be risky, however, because there are many imitation products with misspelled variations of the phentermine name.

Common Misspellings

• Common misspellings include phentarmine, phentramine, phentremine, fentermine, fentiramine, phentiramine and phentirimine.

Phentermine and Fastin

• Fastin was originally a trade name for phentermine, owned for many years by a subsidiary of SmithKline Beecham, but it stopped making the product over a decade ago. A supplement company known as Hi Tech Pharmaceuticals picked up the Fastin name and applied the name to its product, phenylethylamine HCL, which is an over-the-counter supplement that is nothing like phentermine. The pills it makes are designed to look very similar to generic phentermine. Be careful not to take these look-alike pills.

The Real Deal

• If you are interested in trying phentermine or phentermine HCL, they are considered Schedule IV controlled substances by the FDA and DEA and hence cannot be legally purchased without a doctor's prescription.
