The price tag on weight loss prescriptions can range from affordable to truly eye-opening. Factors like drug class, insurance coverage, and pharmacy choice all play a part.

Semaglutide is the most sought-after GLP-1 medication for both diabetes and obesity. Uninsured cash prices currently average $1,100 per month. With commercial insurance, monthly copays can be as low as $25—with prior authorization and manufacturer copay cards—but approval rates for weight management indications remain inconsistent as of 2024.
Tirzepatide, launched for obesity as Zepbound, is the highest-efficacy prescription as of 2024. Without insurance coverage, expect cash prices up to $1,350/month. Manufacturer savings programs occasionally drop monthly cost to $25–$100 for those with qualifying insurance—though patient assistance eligibility is narrow.
Still widely prescribed, liraglutide (Saxenda) often appears on insurance formularies for both diabetes and obesity. Cash price hovers around $1,200/month, with discount cards commonly reducing the patient share to $200–$350/month. Medicaid and some ACA plans cover it for qualifying patients.
The most prescribed oral weight loss medication, phentermine is dramatically less expensive than GLP-1s—especially for uninsured patients. Most pharmacies offer 30-day supplies between $15 and $50. Coverage by insurance is variable; most copay assistance does not apply.
Pricing is rarely straightforward. List prices are just the start—your final out-of-pocket depends on a tight weave of insurance rules, pharmacy benefit managers (PBMs), and manufacturer discounts. Here’s what to know:

Some commercial insurance plans cover select medications, such as Saxenda or Wegovy, with prior authorization. Medicare typically excludes coverage for obesity drugs, while Medicaid varies by state. Always check your plan’s formulary and ask your prescriber’s office to run a coverage check before filling a prescription.
Phentermine is usually the lowest-cost option, with most 30-day supplies under $60, even without insurance. Other older generic medications (like orlistat) may also be affordable, but new GLP-1s (semaglutide, tirzepatide) are much more expensive unless covered by insurance or patient assistance.
Savings cards are issued by pharmaceutical manufacturers and usually lower copays for eligible, commercially insured patients. They cannot be used with government insurance (Medicare/Medicaid) or for uninsured/self-pay. Most cards require the prescription be filled at a participating pharmacy, and have annual maximum savings limits.
Typically, the monthly cost refers only to the pharmacy price for medication. Initial evaluations, lab monitoring, and follow-up visits are billed separately unless bundled in a specialty clinic’s cash program. Ask your prescriber for a full breakdown of all potential costs before starting.
As of early 2024, there are no FDA-approved generic versions of semaglutide, tirzepatide, or liraglutide for weight loss. Some “compounded” versions may be available from certain pharmacies, but these can involve risks and are not recommended unless under strict medical oversight.
