The Oral GLP-1 Revolution
Until recently, every FDA-approved GLP-1 medication for weight loss required a weekly injection. That changed with the approval of Oral Wegovy® (oral semaglutide) and Foundayo™ (oral orforglipron) — giving patients needle-free options for the first time. Today, patients choosing between GLP-1 medications face a meaningful decision: oral pill or injectable.
Both formats deliver clinically significant weight loss. The right choice depends on your lifestyle, needle comfort, and the specific medication that best fits your health profile.
The Oral Options
Foundayo™ (Oral Orforglipron)
Foundayo™ is the only FDA-approved oral GLP-1 that can be taken any time of day — no food or water restrictions. It's a small-molecule drug (non-peptide), which means it's absorbed through the gut without the timing restrictions that peptide-based pills require. Clinical trials (ATTAIN-1) showed 12.4% average body weight loss at the highest dose. Available through LillyDirect at $149/month.
Oral Wegovy® (Oral Semaglutide)
Oral Wegovy® is the first FDA-approved GLP-1 pill for weight loss. It uses the same active ingredient as injectable Wegovy® but in pill form. OASIS trials showed 15.1% average weight loss at the 50mg dose. It must be taken on an empty stomach with limited water. Available through NovoCare at $149/month.
The Injectable Options
Wegovy® (Semaglutide Injection)
Wegovy® is the established standard of care — a once-weekly injection with STEP trial data showing 14.9% average weight loss. It's also the first GLP-1 with proven cardiovascular risk reduction (SELECT trial). Available through NovoCare at $199/month.
Zepbound® (Tirzepatide Injection)
Zepbound® is a dual-action GLP-1/GIP agonist with the highest average weight loss of any approved medication — 22% in the SURMOUNT trials. Available as Vials or KwikPen through LillyDirect at $299/month.
