Help patients afford Adipex-P with this provider guide to generic pricing, discount coupons, patient assistance programs, and cost conversations.
When you prescribe Adipex-P (Phentermine) for weight management, you're giving your patient one of the most effective and affordable short-term appetite suppressants available. But "affordable" is relative. For patients on tight budgets, without adequate insurance, or confused by pricing at the pharmacy counter, even a low-cost medication can become a barrier to adherence.
This guide is designed for prescribers, clinical pharmacists, and care team members who want to proactively help patients access Adipex-P at the lowest possible cost — and build cost transparency into their weight management workflow.
Understanding the pricing landscape helps you set expectations during the prescribing conversation:
The takeaway: generic Phentermine is remarkably inexpensive, but patients don't always know this. Many assume their prescription will cost what they've heard about newer weight loss drugs like Wegovy ($1,000+/month) and may delay or avoid filling their prescription as a result.
A simple statement during the visit — "This medication should cost you less than $15 a month with a coupon, and your insurance may cover it for even less" — can eliminate sticker shock before it starts.
As of 2026, the landscape for brand-specific manufacturer support is limited:
In practice, because generic Phentermine is so inexpensive, manufacturer assistance programs are rarely the most impactful intervention. Your uninsured patients will benefit more from discount coupons and pharmacy selection.
Free discount programs are the single most effective cost-reduction tool for generic Phentermine. Here are the major options to recommend:
GoodRx consistently offers the lowest prices for generic Phentermine — often $4–$10 for 30 tablets depending on the pharmacy. Patients can search for pricing at goodrx.com, show the coupon on their phone at the pharmacy, and pay the discounted cash price. GoodRx Gold members may see prices as low as $1.80.
SingleCare offers comparable pricing and is accepted at most major pharmacy chains including CVS, Walgreens, and Walmart. Patients can get a free card at singlecare.com.
Multiple additional platforms offer competitive pricing for Phentermine. Encourage patients to compare prices across 2–3 platforms since pricing varies by pharmacy and location.
Walmart's $4 generic prescription program includes Phentermine at many locations, making it one of the cheapest options for patients without insurance. No coupon required — patients just need to ask the pharmacy.
Consider keeping a printed handout or digital resource with links to 2–3 coupon platforms (GoodRx, SingleCare, Walmart $4 list) that your front desk or nursing staff can provide at checkout. This takes the guesswork out of saving for patients who aren't tech-savvy.
This is where providers have the most direct impact on patient costs:
Generic Phentermine Hydrochloride 37.5 mg is therapeutically equivalent to brand-name Adipex-P and costs a fraction of the price. Unless a patient has a documented intolerance to a specific generic manufacturer's formulation, there is rarely a clinical reason to prescribe brand-name.
When writing prescriptions, ensure "dispense as written" (DAW) is not checked unless you have a specific reason. Some EHR systems default to brand names — verify that generic substitution is permitted.
For patients who experience side effects at 37.5 mg, consider:
If a patient's insurance doesn't cover Phentermine or they need longer-term treatment, consider these alternatives:

Cost shouldn't be an afterthought. Here are practical ways to integrate affordability discussions into your weight management practice:
When you prescribe Phentermine, tell patients approximately what they should expect to pay. A simple statement like "Generic Phentermine typically costs $5–$15 a month — I'll make sure we prescribe the generic" builds trust and removes a major barrier to filling the prescription.
At follow-up visits, ask: "Have you had any trouble affording your medication?" Patients often won't volunteer this information, but they'll answer honestly when asked directly.
Train front desk and nursing staff to:
Many modern EHR systems integrate real-time pharmacy benefit information. If your system supports it, check the patient's expected copay before sending the prescription. This allows you to address cost concerns in real time.
If a patient reports cost as a barrier, document it in the chart. This supports prior authorization requests, appeals, and future prescribing decisions. It also helps identify patients who may benefit from a PAP referral.
Phentermine is already one of the most affordable prescription weight loss options available — but patients don't always know that. By proactively addressing cost at the point of prescribing, equipping your staff with coupon resources, and screening for financial barriers at follow-up, you can remove one of the most common obstacles to medication adherence.
