Quick read · 5 min

Last reviewed: June 2026Based on 2 clinical trialsEvery claim linked to source

Two FDA-approved GLP-1 pills for weight loss. Oral semaglutide is Wegovy pill (Novo Nordisk). Orforglipron is Foundayo (Eli Lilly). Here is how they compare in clinical data.

Weight loss at maximum dose

Separate trials — no head-to-head data exists between these two drugs. Results from 68-week clinical trials at maximum approved dose.

Oral Wegovy(semaglutide pill)16.6%(~40 lbs)
Foundayo(orforglipron)12.4%(~30 lbs)

For a 240 lb person. Averages from separate studies — no direct head-to-head comparison exists. Individual results vary substantially.

Monthly cost self-pay

Both are similar at entry level. With insurance, both are typically ~$25/month.

Oral Wegovy(semaglutide pill)~$149/mo
Foundayo (lowest dose)(orforglipron)~$149/mo
Foundayo (highest dose)(orforglipron max)~$349/mo

List prices and manufacturer self-pay programs. Insurance coverage varies.

No head-to-head trial exists. Oral semaglutide data comes from a Novo Nordisk trial; orforglipron data from two Eli Lilly trials. The comparison above uses data from separate studies, which is less definitive than a direct comparison.

Side effects comparison

From each drug's main weight loss trial. Both are oral GLP-1s with similar stomach side effects during dose escalation.

Beyond weight loss

Daily routine

Oral semaglutide
Strict 30-minute fast required — no food or water before eating
Orforglipron
Zero food timing restrictions — take anytime, eat immediately after

Heart benefit

Semaglutide
20% reduction in major heart events — proven in SELECT trial (17,604 adults)
Orforglipron
No heart outcomes data yet — blood pressure improvements observed in trials

Side effects

Nausea (both drugs)33–44%
Quit due to side effects~7%
Peaks at weeks2–4

Neither profile is dramatically different from the other

Key trade-off

These two pills differ on weight loss (oral semaglutide higher), convenience (orforglipron much simpler — no fasting), and heart evidence (semaglutide proven, orforglipron pending). Neither is universally better — they suit different priorities. A doctor can help you decide based on your medical history and schedule.
