Wegovy Shots vs. Wegovy Pills for Weight Loss?

Semaglutide has gotten a lot of attention over the past few years. If you don’t recognize this generic drug name, you probably do recognize the brand names: Ozempic for type 2 diabetes and Wegovy for weight loss. Both these GLP-1 agonist medications are self-administered injections, but not everyone is enthusiastic about needles. Rumor has it that a new oral version of semaglutide (Wegovy pills) is poised for entry into the marketplace for weight loss. That’s because a recent study in the New England Journal of Medicine (Sept. 18, 2025) demonstrated success! So here’s the question: Wegovy shots or Wegovy pills for weight loss? It’s a lot more complicated than you might imagine.

How Well Did Oral Semaglutide Work for Weight Loss:

First, a little surprise. There has been an oral form of semaglutide for over six years. It’s called Rybelsus and the FDA approved a variety of doses: Rybelsus R1 formulation comes in 3 mg, 7 mg and 14 mg pills. Then there’s Rybelsus R2 formulation that comes in 1.5 mg, 4 mg and 9 mg pills. These oral formulations are approved for glucose control in the treatment of type 2 diabetes. The maximum daily dose = 14 mg of semaglutide.

Rybelsus has not been FDA approved for weight loss, even though it contains the same active ingredient, semaglutide, that is found in Wegovy shots. But we have a suspicion that a new oral formulation of semaglutide is about to hit the marketplace.

The New England Journal of Medicine Research:

As mentioned above, a study of oral semaglutide (25 mg) was published in the New England Journal of Medicine (Sept. 18, 2025). At the start of the study 205 participants were randomly assigned to get semaglutide and 102 participants were randomly assigned to get placebo pills. At the end of the trial the people in the oral semaglutide group did significantly better than those on placebo:

RESULTS:

“In the oral semaglutide group, 152 of 192 of the participants with an observation at week 64 (79.2%) had a reduction in body weight of 5% or more, 121 (63.0%) had a reduction of 10% or more, 96 (50.0%) had a reduction of 15% or more, and 57 (29.7%) had a reduction of 20% or more; in the placebo group, 28 of 90 of the participants (31.1%) had a reduction of 5% or more, 13 (14.4%) had a reduction of 10% or more, 5 (5.6%) had a reduction of 15% or more, and 3 (3.3%) had a reduction of 20% or more.”

Here is how the authors describe the potential benefits of oral semaglutide (Wegovy Pills):

“Currently available GLP-1 receptor agonists for the treatment of obesity are administered subcutaneously; oral formulations that do not compromise efficacy would offer patients greater choice. The reasons patients may prefer oral administration over the subcutaneous route are most often needle aversion and local skin reactions. In addition, unlike injectable agents, oral agents may not require a refrigerated chain of delivery and could widen the reach of obesity care in many regions of the world where a lack of refrigeration represents a barrier to access.”

The Bottom Line on Wegovy Pills:

Not surprisingly, oral semaglutide performed better than placebo. Almost one third of the people taking Wegovy pills lost at least 20% of their body weight. That’s not shabby.

A Word About the Name Wegovy Pills:

We are only speculating about the name for the oral semaglutide formulation that Novo Nordisk will ultimately bring to market for weight loss. Many drug companies like to come up with new names for different uses of the same medicine. Hence we have Ozempic for semaglutide when the drug is injected for type 2 diabetes. Then there is Wegovy when it is injected for weight loss. And Rybelsus is the name for oral semaglutide when it is used for type 2 diabetes.

So what will the company call oral semaglutide when the drug is prescribed for weight loss? There is a rumor that the company will market Wegovy pills as well as Wegovy shots to help people lose weight. The dose will be higher than oral Rybelsus for diabetes. I’m betting that the company will bring out 25 mg pills and maybe even a higher dose. Remember, the diabetes doses range between 1.5 and 14 mg.

What About the Side Effects of Wegovy Pills?

If we look at the side effects associated with oral Rybelsus at a dose of 14 mg we see that the active drug caused:

• Nausea in about 20% of patients
• Abdominal pain in about 11% of patients
• Diarrhea in about 10% of patients
• Decreased appetite in about 9% of patients
• Vomiting in about 8% of patients
• Constipation in about 5% of patients

In the oral semaglutide study published in the New England Journal of Medicine, the side effects reported at the 25 mg dose were:

• Nausea in about 47% of patients
• Vomiting in about 31% of patients
• Nasal symptoms in about 21% of patients
• Constipation in about 20% of patients
• Indigestion in about 18% of patients
• Diarrhea in about 18% of patients
• Headache in about 12% of patients
• Burping in about 10% of patients

Another Downside of Wegovy Pills:

You might think that people would much prefer oral medicine to an injection. A diabetes expert we consulted challenged that idea. He pointed out that oral semaglutide (Rybelsus) for diabetes has these “important” instructions:

• “Take RYBELSUS on an empty stomach in the morning with water (up to 4 ounces of water). Do not take RYBELSUS with other liquids besides water.
• After taking RYBELSUS, wait at least 30 minutes before eating food, drinking beverages or taking other oral medications.
• Swallow tablets whole. Do not split crush or chew.”

A lot of people hit the ground running in the morning…metaphorically, that is. They may not have time to wait 30 minutes before having a cup of coffee or tea and eating breakfast. Instead of self-injecting semaglutide once a week, people have to take a pill every day. That’s one more thing to remember. And it will slow some folks down.

Microdosing Semaglutide vs. a Wegovy Pill:

I am not going to go into much detail on microdosing semaglutide shots. This is not FDA-approved! It is considered experimental and unproven. But we have been hearing through the grapevine that some people are injecting smaller doses of semaglutide to reduce the risk of side effects.

Some doctors are supervising this strategy to “personalize” the dose. The goal is to maintain effectiveness and reduce the likelihood of adverse reactions. It clearly needs thorough testing, something the drug company may not want to do.

Final Words:

Will the FDA approve oral semaglutide for weight loss? Will the drug company name this formulation Wegovy pills? Time will tell. In the meantime, please let friends and family know that if they have been trying to lose weight for a long time and if they hate shots, oral semaglutide just might be an option.
