HomeHow Much Does Phentermine Cost?How Much Does Phentermine Cost? Sally Cohen Last Updated: October 16, 2019 One of the main reasons for phentermine’s enduring popularity is its cost. It’s the most affordable drug in its class and remains the most-commonly prescription appetite suppressant in the US (1, 2 ).Still, for people on a tight budget, the fact that many insurance companies choose not to cover anti-obesity drugs like phentermine, or only cover them in specific cases, proves problematic.Thankfully, there are several ways to buy phentermine for less – even if insurance does not cover it. Is Phentermine Covered by Insurance? Phentermine's cost is an important consideration for many patientsSome insurance companies cover phentermine as a treatment for obesity, but most do not.Experts estimate that about one third of insurance companies cover all FDA-approved weight loss medications, another third cover some drugs in some cases, while the remaining third do not cover any pharmaceutical therapy for obesity ( 3 ).Medicaid and other government insurance programs do NOT cover phentermine or any other anti-obesity medication in most states ( 4 ).Lack of insurance coverage for weight loss medications is related to:1. MoneyWeight loss significantly improves health outcomes for the vast majority of patients, but insurance companies may not see those savings for years to come. So, profit-driven insurance companies, especially those with high patient turnover, are often hesitant to cover preventative treatments like weight loss medications.2. Safety ConcernsThe US Preventative Task Force repeatedly fails to recommend pharmaceuticals as an advisable treatment for obesity in the primary care setting ( 5 ). A number of experts other experts also believe that the risk of serious side effects from phentermine far outweighs any potential benefit. So, safety concerns in the absence of proven efficacy act as another barrier to more-universal insurance coverage.3. ReputationFinally,weight loss medications have a reputation problem too. Doctors and insurance companies both remember past diet pill debacles and remain overly-cautious about encouraging their use ( 3 ).The Phen-Fen crisis of the late 1990s – wherein multiple patients died of primary pulmonary hypertension (PPH) and heart valve irregularities after taking a combination of phentermine and [now-discontinued] fenfluramine – is still fresh in many experts’ minds ( 6 ).As a result, many providers (and insurance companies) are hesitant to wholeheartedly endorse any new prescription diet pills.Given the scarcity of insurance coverage for anti-obesity medications, research insurance coverage before going-in for a weight loss consult. If your insurance plan does not cover phentermine, ask your doctor to prescribe a more affordable, generic pill instead of a brand name option like Adipex-P or Qsymia.How Much is Phentermine Without Insurance? Generic phentermine pills are relatively affordable, even without insuranceWithout a prescription, a month’s worth of phentermine costs anywhere from $30 to over $200 depending on the brand, form and dosage.
