Both Foundayo[1] and Wegovy[2] have a boxed warning, the most serious type of warning from the Food and Drug Administration (FDA). They are contraindicated in patients with a personal or family history of thyroid C-cell tumors, including medullary thyroid carcinoma (MTC). They are also contraindicated in patients with Multiple Endocrine Neoplasia syndrome type 2 (MEN 2). Remember to discuss the potential risks of either of these medications with your healthcare provider.

Highlights

  • Both Foundayo and Wegovy are FDA-approved for chronic weight management and can help with weight loss.
  • Wegovy is available as an injection and a tablet while Foundayo is only available as a tablet.
  • MEDvidi has licensed healthcare providers in multiple states who are able to prescribe Foundayo or Wegovy online after a detailed health assessment if deemed clinically necessary.

Many new medications are being approved to help with weight loss and weight management. The majority of these medications are glucagon-like peptide-1 (GLP-1) receptor agonists and have historically only been available as a weekly injection. Recently, several tablet forms of GLP-1 medications have been approved, such as Wegovy and Foundayo. 

If you are considering a medication to help with weight loss or weight management and are comparing Foundayo vs Wegovy, this guide will help you understand how each medication works, the standard dosage, and what you can expect from the medications. This knowledge will help you in your discussion with a healthcare provider.

What Are Foundayo and Wegovy

Both Foundayo and Wegovy are GLP-1 medications but they contain different active ingredients and are slightly different examples of GLP-1s. 

Wegovy

Wegovy contains the active ingredient semaglutide, which is a peptide GLP-1. It is available both as a weekly injection and as a tablet. Because it is a peptide — and peptides are broken down by stomach acid and digestive enzymes — it also has a specific ingredient in the tablets that helps to enhance its absorption into the body. 

Foundayo

Foundayo is a once-daily medication that is available as a tablet. It contains the active ingredient orforglipron. It is a unique GLP-1 in that it is a non-peptide, which means that it has a different chemical structure. This structure allows it to be more stable in the digestive tract and not broken down as easily so that it can be absorbed into your body.

How Foundayo and Wegovy Work for Weight Loss

Both medications tell your stomach and your brain that you feel full. This enables you to stick to a diet without experiencing overwhelming cravings or food noise. GLP-1 medications work specifically on the GLP-1 pathways by doing the following:

  • Slowing gastric emptying
  • Reducing appetite signals
  • Altering your reward pathway, so food cravings are not as intense

Is Foundayo or Wegovy Better for Weight Loss?

Both Foundayo and Wegovy are effective for weight loss. In clinical trials for Foundayo[1] , participants lost up to 11% of their body weight during 72 weeks of treatment. In clinical trials of Wegovy[2] , participants lost up to 16% of their body weight by week 68.

The biggest takeaway is that both Foundayo and Wegovy caused significant weight loss in clinical trials. One of the most important factors to being successful in losing weight on either medication is how your body tolerates the medication, what side effects you experience, and whether you make the necessary lifestyle adjustments, such as eating a balanced, reduced-calorie diet and increasing physical activity.

Consult a licensed medical provider online to find out what weight loss option may be right for you.

Foundayo and Wegovy Dosage

Both Foundayo and Wegovy are usually started at a lower dose and titrated up slowly to an ongoing maintenance dose. This is so that your body has time to adjust to the medication, which helps to deal with side effects and monitor your response to the medication better.

Side Effects and Interactions of Foundayo and Wegovy

Since both Foundayo and Wegovy are GLP-1 medications, they have very similar side effect profiles. Most of the common side effects are related to gastrointestinal issues and often get better as you continue the medication for longer. 

Common Side Effects of Foundayo and Wegovy

Both Foundayo[1] and Wegovy[2] can cause:

  • Nausea and vomiting

Serious Side Effects of Foundayo and Wegovy

The list above is not exhaustive, and different patients may experience different adverse reactions. Consult your healthcare provider to make sure any other health conditions do not increase the risk for side effects.

Drug Interactions

Both Foundayo and Wegovy slow gastric emptying and can interfere with the absorption of oral medications. Foundayo can interfere with certain medications that induce or inhibit an enzyme called CYP3A4 that helps to break down medications. 

It’s important to tell your healthcare provider about all prescription and over-the-counter medications, herbs, and supplements, so they can make sure Foundayo or Wegovy is safe for you. 

"Most GLP-1 side effects are gastrointestinal and often improve with time, but patients should still report persistent nausea, vomiting, abdominal pain, dehydration, or symptoms of low blood sugar. These symptoms may require dose adjustment, closer monitoring, or a different treatment approach. "

Foundayo and Wegovy Cost

Both Foundayo and Wegovy are only available for weight loss as brand-name medications. The list price of Wegovy is $1349.02 for a monthly set of tablets or injections. However, there are multiple ways to save, from insurance coverage to discount programs. With the manufacturer’s offer for new patients, one will pay $199 to $349 for a one-month supply of Wegovy pens and from $149 for a monthly supply of Wegovy tablets.

Foundayo costs around $780 when paying cash. It also has a discount program from a manufacturer, resulting in monthly expenses of $149 to $299, depending on the dosage.

If you qualify for your insurance to cover weight loss medications, the cost may be even less. You should talk with your pharmacy, prescriber, and your insurance carrier to determine the cost of Foundayo or Wegovy for you.

What to Ask Your Provider About Weight Loss Medications

If you believe a weight loss medication may be helpful for you, talk with your healthcare provider. Here are examples of certain questions you can discuss:

  • Will a GLP-1 medication help me lose weight? 
  • How much weight can I expect to lose? 
  • Which weight loss medication may be the best fit for me? What if it doesn’t work? 
  • What side effects should I be aware of with GLP-1 weight loss medications?

Your healthcare provider may also suggest other medications or non-medication options to help your symptoms, including diet and exercise goals. They will also discuss your past attempts at losing weight and what has or has not worked for you.

FAQs

Yes, it is possible for you to switch from Wegovy to Foundayo if deemed appropriate by your clinician. Talk with your healthcare provider, and they will help to make a plan for you to safely switch medications. You may need to start at a lower dose of Foundayo and titrate up to a maintenance dose. 

Because Wegovy tablets have an ingredient that helps improve absorption, there are certain food requirements. This includes taking Wegovy tablets on an empty stomach and at least 30 minutes before any food. It’s also important to take the medication with only a small amount (up to 4 ounces) of plain water. 

No, Foundayo and Wegovy should not be taken together. It is not recommended to combine GLP-1 medications, and taking two of these medications will not increase or speed up weight loss. Taking Foundayo and Wegovy together can increase your risk of severe side effects. It is recommended to follow a weight loss diet and exercise routine with a GLP-1 medication to maximize weight loss. 

When taking GLP-1 medications like Foundayo and Wegovy for weight loss, it is important that you eat healthy and eat enough protein to maintain your muscle mass. Talk with your healthcare provider about the recommended amount of daily protein that is right for you. They may also suggest you work with a nutritionist to ensure you are eating a proper diet. 

Obesity is considered a chronic medical condition. Research has shown that when people stop taking GLP-1 medications, they are likely to regain the weight they lost. GLP-1 medications are intended to be used long-term. Talk with your healthcare provider about how long you can expect to take Foundayo or Wegovy.
