Foundayo™ is the newest name on this list, and people are talking about it for one big reason: it is a pill, not a shot.

The FDA approved it on April 1, 2026. Here is what it is, in plain words.

The short version

  • Foundayo™ is a once-a-day pill for weight loss.
  • The medicine inside is orforglipron.
  • You can take it any time of day — no rules about food or water.
  • In studies, people lost about 12% of their body weight (around 27 pounds).
  • You need a prescription to get it.

What is it?

Foundayo™ is made by Eli Lilly. A doctor gives it to adults to help them lose weight and keep it off, when extra weight is a health risk.

It is special because it is a daily pill in a group of medicines that usually come as shots. It is the only GLP-1 pill you can take any time of day, with or without food or water.

What is it used for?

  • Help adults lose weight when it is a health risk.
  • Help keep weight off, with healthier eating and more movement.
  • Give people a choice with no needles.

How does it work?

Like the shots on this list, Foundayo™ copies your gut’s natural “full” signal, called GLP-1.

The clever part is that it does this as a small pill. So your stomach empties slower and you feel full sooner — no needle needed.

Shot or pill? How you take it

Foundayo™ is a pill you swallow once a day. You can take it morning, noon, or night — whatever fits your day.

It comes in a few strengths. Your provider starts you low and moves you up slowly, so your body can adjust.

How it compares to the others

Five big names get mixed up a lot. Here is how they line up:

Brand Medicine Made by Shot or pill? Mainly for
Zepbound® tirzepatide Eli Lilly Weekly shot Weight loss
Mounjaro® tirzepatide Eli Lilly Weekly shot Type 2 diabetes
Ozempic® semaglutide Novo Nordisk Weekly shot Type 2 diabetes
Wegovy® semaglutide Novo Nordisk Weekly shot (or a pill) Weight loss
Foundayo™ (this one) orforglipron Eli Lilly Daily pill Weight loss

What about side effects?

Side effects to know

The most common side effects are tummy problems, mostly at the start:

  • Feeling sick to your stomach
  • Diarrhea or constipation
  • Upset stomach or throwing up
  • Less appetite

These often get better over time. A few can be serious, so your doctor will go over the warning signs.

The good and the not-so-good

What people like

  • It is a pill, not a shot
  • Take it any time of day, food or not
  • No needles, no fridge needed
  • Brand-new and easy to start

What to keep in mind

  • You take it every day, not weekly
  • Newer, so less long-term track record
  • Tummy side effects at first
  • Prescription only

Common questions

Is Foundayo™ a shot?

No — it is a once-a-day pill. That is the whole point. If you want a shot, see Zepbound® or Wegovy®.

How is it different from the Wegovy® pill?

Both are GLP-1 pills for weight loss. Foundayo™ can be taken any time of day, with no food or water rules. That is its big plus.

How much weight do people lose?

In studies, people on the top dose lost about 12% of their body weight — around 27 pounds — with diet and exercise. Results vary.

Do I need a prescription?

Yes. A licensed doctor decides if Foundayo™ is safe and right for you.
