The GLP-1 obesity-treatment landscape is expanding in 2026 with the arrival of oral GLP-1 pills, new high-efficacy injectables like retatrutide, and broader cash-pay and retail discount programs. Oral Wegovy is expected to improve access and may be less expensive for cash payers, though strict dosing affects effectiveness. Retatrutide has shown nearly 29% average weight loss at the highest dose but comes with higher side-effect and dropout rates. Experts emphasize the need for specialist oversight and clear conversations about costs and expectations.
What to Watch in Weight-Loss Drugs in 2026: Oral GLP-1s, Potent New Injectables and Price Shifts

The GLP-1 treatment landscape is changing rapidly in 2026: oral versions of established drugs, new ultra-potent injectables and expanded cash-pay programs promise wider access — but higher efficacy can bring stronger side effects and ongoing affordability and care-quality concerns.
Oral GLP-1 Pills Arrive
Novo Nordisk recently received FDA approval for the first oral GLP-1 weight-loss medication, marketed as the Wegovy pill, and the product is expected to be widely available soon. Eli Lilly also plans to bring an oral GLP-1 to market in the near future.
Why it matters: Pills remove the barrier of injections for people who dislike needles and may lower cash prices compared with injectables, increasing convenience and potential uptake.
Pricing and Access
Company pricing announcements indicate the two lowest doses of the Wegovy pill will cost about $149 per month for cash-paying customers, with higher pill doses priced at $299 per month; insured patients could see out-of-pocket costs as low as $25 in some cases. By comparison, the lowest-dose Wegovy injection has been offered at around $349 per month for cash payers.
Retailers and manufacturers have rolled out cash-pay programs and discounts in recent years. Examples include discounted programs by Lilly and Novo Nordisk, retailer deals at Costco and Walmart, and the planned 2026 TrumpRx.gov portal, which will link consumers to drugmakers' discount sites. Projections cited by officials suggest injection prices on that platform could start near $350 per month and fall over time.
Efficacy, Dosing and Real-World Use
The new oral Wegovy regimen must be taken every morning on an empty stomach to achieve the best results. In a late-stage trial, participants who adhered to the strict schedule lost an average of 16.6% of body weight, while those who did not follow the regimen exactly lost 13.6% on average. Lilly’s upcoming oral option allows more flexible timing but still requires daily dosing.
Patient experience underscores potential benefits and limits. One trial participant reported losing about 40 pounds over roughly 18 months on the oral medication, improving energy and eating habits, but many patients will need individualized counseling about expectations and costs.
Retatrutide: Very High Efficacy, Higher Dropout
Eli Lilly’s experimental injection retatrutide — which targets GLP-1, GIP and glucagon — produced very large weight losses in Phase 3 testing. Lilly reported nearly 29% average weight loss at the highest dose after roughly 16 months in a trial of about 450 adults.
However, higher efficacy has been paired with more intense side effects and higher discontinuation: retatrutide’s highest-dose group had an 18.2% dropout rate versus 4% for placebo in the reported trial, and adverse events included nausea, diarrhea, constipation and vomiting. By contrast, a high-dose Zepbound trial reported a 6.2% dropout rate.
Clinical takeaway: Retatrutide may offer an option for people with severe obesity or those who have not responded to other GLP-1 therapies, but clinicians and patients should weigh greater potential benefit against higher side-effect and discontinuation risks. Lilly is wrapping up additional trials with completion expected in 2026 and may file for regulatory approval soon.
Care Delivery and Safety Considerations
Expanded self-pay and telehealth programs can improve access for patients whose insurance does not cover anti-obesity medications. However, experts stress the importance of proper medical oversight: patients should be assessed and followed by clinicians experienced in obesity medicine to manage dosing, expectations, side effects and long-term care.
“The GLP-1 landscape is expected to broaden significantly,” said Dr. Christopher McGowan. “For the first time, medical obesity treatment will move away from a one-size-fits-all model.”
As new formulations, pricing models and powerful investigational drugs appear, patients and clinicians will face choices about efficacy, safety, convenience and affordability. Ongoing data, transparent pricing and careful clinical follow-up will be critical to realizing the benefits while minimizing harms.
