What does insurance cover?

Insurance coverage varies widely by plan, employer, and country. Some plans cover GLP-1 medications for diabetes but not for weight loss. Others cover weight loss medications with restrictions (like requiring proof of failed diet first). Check with your insurer about coverage criteria.

What are manufacturer savings programs?

Companies like Eli Lilly (LillyDirect) and Novo Nordisk (NovoCare) offer co-pay assistance programs for eligible patients with commercial insurance. These can reduce out-of-pocket costs significantly compared to the list price — the exact amount depends on your plan and income. Eligibility criteria vary; each medication's cost page has its own programme figures.

Is oral semaglutide cheaper because it is less effective?

No. The oral formulation (Wegovy pill) is chemically identical to the injection but requires daily dosing instead of weekly. It was priced lower due to manufacturing scale and market dynamics, not efficacy differences.

Do prices include all the costs?

List prices shown here are for the medication only. You may also have doctor visit costs, lab work, and monitoring. Some medications require weekly or monthly visits; others can be managed with less frequent check-ins.

Do prices ever go down?

Yes. Oral semaglutide, approved in late 2025, is priced by dose at $149–$299/month — a dramatic price drop from the injection. Generic versions of older medications are available. GLP-1 generic versions may become available as patents expire.

Is GoodRx useful for weight loss drugs?

GoodRx can reduce prices for some medications, especially generics like phentermine/topiramate and naltrexone/bupropion. For brand-name GLP-1 drugs, manufacturer savings cards typically offer better discounts than GoodRx. It is worth checking both.

Are compounded versions of GLP-1 drugs safe?

Compounded semaglutide and tirzepatide are available from some pharmacies at lower prices, but they are not FDA-approved and quality control varies. The FDA has issued warnings about some compounded products. If you choose a compounded version, use only a licensed 503B outsourcing facility and discuss with your doctor.

Should I switch drugs to save money?

Possibly. If you are on an expensive injectable and responding well, ask your doctor about switching to a cheaper oral version (like oral semaglutide, $149–$299/month by dose). If you need the strongest possible weight loss, the cost difference may be worth it. This is a conversation with your prescriber.

How much does weight loss medication cost?

Monthly cost, self-pay or generic price (reviewed September 2026)

From cheapest to most expensive — before insurance. List price is shown separately where it differs from the self-pay range.

Generic phentermine/topiramate$30–$80/mo

Orlistat OTC (Alli)$40–$60/mo

Naltrexone/bupropion (Contrave)$100–$400/mo

Oral Wegovy / Foundayo$149–$349/mo

Tirzepatide (Zepbound, LillyDirect self-pay)$299–$449/mo (list price ~$1,086/mo)

Liraglutide (Saxenda)$1,000–$1,349/mo

Semaglutide injection (Wegovy)$349–$399/mo (list price ~$1,349/mo)

Self-pay and generic prices as listed above; list price shown in parentheses where it applies. Insurance, savings cards, and patient assistance programmes can reduce these further.

The landscape changed fast. Oral semaglutide (Wegovy pill), approved in late 2025, is priced by dose at $149–$299/month — making a GLP-1 accessible to far more people. Generic phentermine/topiramate costs as little as $30/month.

Insurance and savings programs

List prices are rarely what people pay. Two things commonly reduce costs significantly:

Manufacturer savings cards — Eli Lilly's LillyDirect and Novo Nordisk's NovoCare can bring monthly costs down to as little as $25 for eligible patients on commercial insurance
Insurance — coverage is inconsistent and varies by plan, employer, and country. Some plans cover GLP-1s for diabetes but not weight loss
Medicare Part D — Foundayo (orforglipron) coverage expected from July 2026 at approximately $50/month

Five ways to reduce what you pay

Get the manufacturer savings card

Both Novo Nordisk (NovoCare) and Eli Lilly (LillyDirect) offer savings programmes. With commercial insurance, your copay may be reduced to as little as $25/month. These cards are free and can be applied at the pharmacy.

Ask about the oral pill version

For semaglutide, the oral pill (Wegovy pill, $149–$299/mo by dose) produced weight loss in a similar range to the injection ($1,349/month at list price) in its own trial, at a fraction of the injection's list price.

Compare pharmacy prices

Prices vary significantly between pharmacies. Use GoodRx or similar tools to compare pricing. Mail-order pharmacies and big-box retailers (Costco, Sam's Club) sometimes offer lower prices.

More ways to reduce what you pay

Check if you qualify for patient assistance

Both manufacturers offer patient assistance programmes for people without insurance or with financial hardship. These can provide medication at no cost for qualifying individuals.

Work your insurance

If your plan denies coverage, ask your doctor about prior authorisation or step therapy. Some plans cover GLP-1s for diabetes but not weight loss — your doctor may be able to document medical necessity.

If cost is a hard barrier right now

If medication is not affordable right now, that does not mean your options are limited. Clinical data supports several non-medication approaches.

Structured diet (caloric deficit)

About 5–8% weight loss on average

See the diet guide

Diet + exercise combined

About 7–10% weight loss on average
