Foundayo and Wegovy are both GLP-1 medications for weight loss. One is a pill. One is an injection. Here's how they compare.
Quick Comparison
| Foundayo | Wegovy | |
|---|---|---|
| Active drug | Orforglipron | Semaglutide |
| Drug class | GLP-1 agonist | GLP-1 agonist |

How They Work
Both medications mimic the GLP-1 hormone. This hormone helps you feel full and slows how fast your stomach empties.
Foundayo uses orforglipron. It's a GLP-1 receptor agonist in pill form.
Wegovy uses semaglutide. It's the same drug as Ozempic, but approved specifically for weight loss.
The main difference is how you take them. Foundayo is a pill. Wegovy is a shot.
Weight Loss Results
From clinical trials:
| Medication | Average Weight Loss | Study Length |
|---|---|---|
| Foundayo (17.2 mg) | ~11% of body weight | 72 weeks |
| Wegovy (2.4 mg) | ~15% of body weight | 68 weeks |
Important: These were separate trials, not head-to-head studies. You cannot directly compare the numbers. They tested different groups of people.
What we can say:
- Both led to meaningful weight loss
- Both worked better than placebo
- Results vary by person
Convenience
Foundayo wins on convenience for people who hate needles.
- Foundayo: Take one pill each day. Anytime. No food or water restrictions.
- Wegovy: One injection per week. You inject it yourself into your stomach, thigh, or upper arm.
Some people prefer weekly injections because they forget daily pills. Others prefer daily pills because needles feel scary or hard.
Neither approach is wrong. Pick what fits your life.
Side Effects
Both cause similar GI side effects:
- Nausea (most common)
- Diarrhea or constipation
- Stomach pain
- Vomiting (less common)
- Decreased appetite
Side effects are usually worst during the first few weeks. They often improve as your body adjusts.
Both medications carry a boxed warning about thyroid tumors seen in rodent studies. The risk in humans is unknown. You should not take either if you or your family have a history of medullary thyroid carcinoma or MEN 2 syndrome.
Dosing
Foundayo dosing:
- Starts low and increases over time
- Maximum dose: 17.2 mg daily
- Taken as a once-daily pill
Wegovy dosing:
- Starts at 0.25 mg weekly
- Increases every 4 weeks
- Maximum dose: 2.4 mg weekly
Both medications use a "start low, go slow" approach. This helps your body adjust and reduces side effects.
Cost
List prices:
- Wegovy: ~$1,350/month
- Foundayo: Pricing varies by pharmacy and insurance
Your actual cost depends on:
- Your insurance plan
- Whether your plan covers weight loss medications
- Manufacturer savings programs
- Whether you use a copay card
Check your formulary for both medications. Coverage varies widely.
Who Should Choose Foundayo?
- You hate needles
- You want a daily routine
- You have trouble with injections
- Your insurance covers it
Who Should Choose Wegovy?
- You prefer weekly dosing
- You want the longer track record
- You've used semaglutide before
- Your insurance covers it
Can You Switch?
Yes. Some people switch if:
- They don't get enough results
- Side effects are too hard
- Insurance changes
- They want to try a different approach
If you switch, you'll start at the lowest dose of the new medication. Talk to your doctor before changing anything.
The Bottom Line
Both Foundayo and Wegovy work for weight loss. The main difference is the pill vs the injection.
If needles are a dealbreaker, Foundayo gives you a real option. If you prefer weekly dosing or want the more established track record, Wegovy may be the better fit.
The right choice depends on what you can stick with, what your insurance covers, and what your doctor recommends.
