The FDA approved oral Wegovy (semaglutide) on December 22, 2025. Eli Lilly received approval for its pill, Foundayo (orforglipron), on April 1, 2026. It will be a fight for America’s fat. Instead of an injection, people who want to shed pounds with a GLP-1 medication can choose between oral medications. That may seem like a huge win for people who hate needles. But the reality may be a bit more complicated.
Many people may assume that pills are way easier than shots. But as you will see shortly, the instructions that come with oral Wegovy could be a bit challenging for some people. And a once weekly shot may be easier to remember and implement than a daily pill.
A diabetes expert we interviewed on our People’s Pharmacy radio show/podcast suggested that weekly injections might actually be easier for some people than a daily pill that has fairly strict timing rules, especially with regard to food and other medications.
Which Pill is Easier? Wegovy or Foundayo?
The instructions for Wegovy tablets are a bit challenging:
- “Take one WEGOVY tablet orally once daily on an empty stomach in the morning with water (up to 4 ounces). Do not take WEGOVY tablets with other liquids besides water.
- “Swallow tablets whole. Do not split, crush, chew or dissolve in any solution.
- “After taking a WEGOVY tablet, wait at least 30 minutes before eating food, drinking beverages or taking other oral medications.”
A lot of people don’t have half an hour in the morning to wait around before eating breakfast.
The instructions for Foundayo are a bit easier:
- “Take FOUNDAYO orally once daily, with or without food.
- “Swallow tablets whole. Do not break, crush, or chew.”
Which Pill Works Better? Wegovy or Foundayo?
There is no good answer to that question. That’s because there have been no head-to-head clinical trials that maintain identical protocols in a “blinded” setting. By blinded I mean that neither the volunteers nor the clinicians know who is getting the real pills and who is getting placebos.
We will have to wait some time to get that kind of data. Drug companies rarely fund this kind of head-to-head comparison. Their goal is to get FDA approval and hope that their marketing teams can convince doctors and patients that they have a better product.
What we have for now are what I would characterize as preliminary data. One of our favorite insider publications that covers the pharmaceutical industry is FIERCE Pharma.
On April 1, 2026 Fraiser Kansteiner shared these data on weight loss in FIERCE Pharma:
“The FDA based its approval on data from Lilly’s ATTAIN clinical program. In the ATTAIN-1 study, patients on the highest dose of Foundayo and who took the treatment as intended lost an average of 27.3 pounds, or 12.4% of their average body weight, versus 2.2 pounds (0.9%) for those who received placebo, Lilly noted in its approval announcement.
“Though comparisons across trials carry inherent flaws, Novo’s Wegovy pill won a U.S. green light based on data showing an average 16.6% weight loss among patients who adhered to treatment.
“In Lilly’s program, patients taking Foundayo regardless of trial completion lost an average of 25 pounds or 11.1% of their average body weight versus 5.3 pounds (2.1%) among their counterparts in the control arm.”
Until there is a head-to-head trial, though, I would hesitate to draw any conclusions about effectiveness.
What About the Cost of Wegovy vs. Foundayo?
Foundayo:
Price is always a hot button issue when it comes to pharmaceuticals. Will insurance pay for the oral medications? That depends upon the insurance company. I can make no predictions.
What I can tell you is that Eli Lilly has implemented something called LillyDirect. It provides online access to pharmacy services. There are “telehealth” providers, which I interpret as clinicians who may be able to prescribe. I won’t weigh in on the pros or cons of such a service at this time. The word on the street is that people who utilize this online approach (without insurance) will be paying around $149 a month for the lowest dose of Foundayo.
Keep in mind that the dose of GLP-1 drugs is often started low and gradually increased over the next several months. The Lilly price may increase as the dose is raised. I have seen estimates of around $299 a month if patients continue to take Foundayo at higher doses.
Wegovy:
The cash price for a starting dose of Wegovy has been reported at around $149 a month. I would not be surprised that as the dose is raised, the cost will climb to about $299 a month. I suspect that this will be a head-to-head battle of two enormous pharmaceutical companies. They will probably not compete on price but rather through advertising on television and other media. Be prepared for the fight for fat in coming months.
What About Side Effects for Foundayo and Wegovy?
Remember, both these drugs are are GLP-1 receptor agonists. That means they work by mimicking a natural hormone called glucagon-like peptide-1 (GLP-1). You can learn more about how such drugs work at this link.
Since both drugs are GLP-1 receptor agonists you might expect the side effects to be somewhat similar. At the highest dose, Foundayo caused the following adverse reactions:
- Nausea……………35%
- Constipation……24%
- Diarrhea…………25%
- Vomiting…………24%
- Indigestion………13%
- Abdominal pain..14%
I have had a hard time finding the side effects of oral Wegovy in the official prescribing information. But I did find some helpful information in a clinical trial of 25 mg of oral semaglutide published in the New England Journal of Medicine (Sept. 17, 2025).
- Nausea……………46.6%
- Constipation…….20.1%
- Diarrhea………….17.6%
- Vomiting…………30.9%
- Indigestion……….18.1%
It may not be fair to compare gastrointestinal side effects from different clinical trials. As mentioned above, the only way to truly compare these two weight loss pills would be to conduct a head-to-head clinical trial using the same exact protocol for both medications.
The Bottom Line on Foundayo and Wegovy Pills
I am not prepared to say that pills are better than injections or vice versa when it comes to weight loss. Some people hate shots, no matter how small the needle. For them, pills will be a better option. Others may find that the once-a-week shots are more convenient.
Oral medicine may be transported more safely, especially in the summer. Injectable drugs may not fare well in the back of a delivery van unless they are maintained in temperature-controlled packaging.
There are lots of questions that remain unanswered:
- Which GLP-1 drug really works better or are they about equal? Only a head-to-head trial can answer that and it may never be done.
- Which GLP-1 drug is safer long term? Again, only a head-to-head trial can answer that question well.
- Which will insurance actually cover? That will likely depend upon the insurance company.
- Will people stay on these drugs for life? That question remains open to debate. We have heard that when people stop their GLP-1 medication the weight comes back.
- And perhaps most important: Who will be able to afford these drugs? If insurance won’t pay, the cost will add up!
