Summary
There are now two FDA-approved GLP-1 pills for weight loss, and they are not the same drug. Dr. Clete Barrick (board-certified in internal medicine and obesity medicine) breaks down the side-by-side: the chemistry, the dosing rules, the weight loss data, the side effects, the cost, and which patient profile fits each pill.
What you'll learn:
- Why Foundayo (orforglipron) and oral Wegovy (semaglutide 25 mg) are pharmacologically different drugs, not just two brands of the same thing
- The morning ritual oral Wegovy requires and why pharmacokinetic studies say you can't cheat it
- Trial weight loss numbers from ATTAIN-1 (Foundayo) and OASIS 4 (oral Wegovy) and what the 1.2-point gap actually means in real life
- The side effect paradox: lower nausea on Foundayo but higher discontinuation at the top dose
- May 2026 self-pay and insured pricing through LillyDirect and NovoCare
- The patient profiles where each pill is the right answer, and the case where a needle is still better than a pill
