Oral GLP-1 Medications: Everything You Need to Know About the New Weight Loss Pills

In This Article

What Are Oral GLP-1 Medications?

Oral GLP-1 medications are a new class of weight loss and diabetes pills that work like the hormone GLP-1 in your body. GLP-1 stands for glucagon-like peptide-1, which is a natural hormone that helps control blood sugar and makes you feel full after eating. These medications copy what this hormone does, but they come in pill form instead of injections.

Until recently, GLP-1 medications were only available as daily or weekly shots. Now, patients can take a daily pill instead. This change makes these powerful medications available to people who don’t like needles or prefer taking pills.

The FDA approved the first oral GLP-1 for weight loss in December 2025. This approval marked a major shift in how doctors can treat obesity.

How Do Oral GLP-1 Medications Work?

These medications work by mimicking your body’s natural GLP-1 hormone in three main ways. First, they act on the part of your brain that controls your hunger. This helps to feel fuller faster while also reducing cravings. Second, they slow down how fast food leaves your stomach, which helps you feel full longer after meals. Third, they help your pancreas make more insulin when your blood sugar is high. Lastly, they reduce how much sugar your liver makes.

The pills are specially designed to survive stomach acid and get absorbed into your bloodstream. This was the biggest challenge in creating oral versions of these drugs. Scientists had to find ways to protect the medication as it travels through your digestive system.

When you take an oral GLP-1 medication, it starts working within hours. However, it takes several weeks to reach full effectiveness. Most people need to start with a low dose and gradually increase it to avoid side effects.

The First Oral GLP-1 for Weight Loss: Wegovy Pill

The biggest breakthrough came with the approval of oral semaglutide 25mg, known as the Wegovy pill. This once-daily tablet contains the same active ingredient as the weekly Wegovy injection, but you take it every day instead of getting a shot once a week.

The Wegovy pill went through extensive testing called the OASIS-4 trial. In this study, people taking the pill lost an average of 14% of their body weight over 64 weeks. People taking a placebo pill only lost about 2% of their weight during the same time period.

This new weight loss pill form launched in early January 2026 and gives patients a new option if they want the benefits of Wegovy but prefer not to use injections. You can learn more about Wegovy options to understand how these medications might fit into your treatment plan.

Comparing Oral vs Injectable Forms

The oral and injectable forms of semaglutide work almost equally well for weight loss. Both versions help people lose 13-15% of their body weight on average. The main differences are in how often you take them and some side effects.

With Wegovy injections, you give yourself a shot once a week. With the pills, you take one tablet every day. Some people find daily pills easier to remember as part of their routine. Others prefer weekly injections because they don’t have to think about medication every day.

The side effects are similar between both forms, but some people may experience more stomach upset with daily pills compared to weekly shots. This happens because your digestive system processes the medication every day instead of once a week.

Other Oral GLP-1 Medications in Development

Several other companies are working on oral GLP-1 medications. Eli Lilly is testing oral versions of tirzepatide, which is sold as Mounjaro for diabetes and Zepbound for weight loss. These medications work on two hormone pathways instead of just one, which might make them even more effective.

Some experimental medications target three or even five different hormone pathways. Early studies show these multi-target drugs might help people lose even more weight. One medication called retatrutide helped people lose up to 28.7% of their body weight in clinical trials.

Researchers are also working on monthly oral medications. These would let people take just one pill per month instead of daily or weekly dosing. This could make treatment even more convenient for patients.

Who Can Take Oral GLP-1 Medications?

Doctors typically prescribe oral GLP-1 medications for adults with type 2 diabetes or obesity. For weight loss, you usually need to have a BMI of 30 or higher, or a BMI of 27 or higher with a weight-related health problem like high blood pressure, high cholesterol, diabetes, or sleep apnea.

These medications work best when combined with healthy eating and regular exercise. They are not magic pills that work without lifestyle changes. Your doctor will want to see that you’re committed to making healthy choices alongside taking the medication.

Some people should not take oral GLP-1 medications. This includes people with certain types of thyroid cancer, severe stomach problems, or a history of pancreatitis. Your doctor will review your medical history to make sure these medications are safe for you.

Side Effects of Oral GLP-1 Medications

Common Side Effects

Most people who take oral GLP-1 medications experience some stomach-related side effects, especially when starting treatment. The most common side effects include:

  • Nausea: Around 45% of people experience some nausea, especially in the first few weeks
  • Vomiting: Less common than nausea, but still affects many people initially
  • Diarrhea: Usually mild and improves as your body adjusts
  • Stomach pain: Often described as cramping or discomfort

Headache and fatigue are also common side effects people experience with Wegovy. These side effects usually get better after a few weeks as your body adjusts to the medication. Starting with a low dose and increasing it slowly helps reduce these problems.

Serious but Rare Side Effects

Some serious side effects can occur, but they happen in less than 1% of people taking these medications:

  • Pancreatitis: Severe stomach pain that doesn’t go away
  • Gallbladder problems: Pain in the upper right stomach area
  • Severe dehydration: From persistent vomiting or diarrhea, or kidney damage
  • Diabetic retinopathy: Eye problems in people with diabetes
  • Possible increased risk of thyroid cancer: Seen in animal studies, it is not known if Wegovy can cause thyroid cancer in people
  • Low blood sugar: More likely if taken with insulin or other diabetes medications
  • Thoughts of suicide or self-harm

If you experience any of these side effects, contact your doctor immediately or seek medical attention.

How Effective Are Oral GLP-1 Medications?

Oral GLP-1 medications are very effective for both weight loss and blood sugar control. In clinical trials, people taking these medications lost 10-15% of their body weight on average. This is significantly more than most other weight loss medications, which typically lead to 5-10% weight loss.

For diabetes control, oral GLP-1 medications help lower A1C levels by 1-2 percentage points. They also provide cardiovascular benefits, reducing the risk of heart attacks and strokes. 1 This makes them particularly valuable for people with diabetes who also have heart disease risk factors.

The medications work best when combined with lifestyle changes. People who follow a healthy diet and exercise regularly while taking oral GLP-1 medications often see even better results than the average clinical trial outcomes.

Cost and Insurance Coverage

Pricing for GLP-1 pills has become more competitive recently. Without insurance coverage, you can expect to pay $149 to $299 per month, depending on the dose. This represents a significant improvement in affordability compared to earlier pricing.

Insurance coverage varies by plan and indication. Many insurance plans cover GLP-1 pills for diabetes treatment, but may have restrictions for weight loss uses. Check with your insurance provider about specific coverage details.

If you need help affording these medications, trusted online pharmacies may offer lower prices than traditional pharmacies. Always make sure you’re working with a legitimate pharmacy that requires prescriptions and is properly licensed.

Taking Oral GLP-1 Medications Safely

Taking oral GLP-1 medications requires following specific instructions to ensure they work properly and safely. Most oral GLP-1 medications need to be taken on an empty stomach, usually first thing in the morning.

You should take the pill with a small amount of plain water, usually no more than 4 oz or about ½ cup. You should then wait at least 30 minutes before eating, drinking anything else, or taking other medications. This waiting period is crucial because food and other substances can interfere with how well your body absorbs the medication.

Your doctor will start you on a low dose and gradually increase it over several weeks or months. This slow increase helps your body adjust and reduces side effects. Never increase your dose faster than recommended, even if you’re not seeing results yet.

Making the Right Choice for Your Health

Choosing between oral and injectable GLP-1 medications depends on your personal preferences, lifestyle, and medical needs. If you’re considering these medications, start by talking with your healthcare provider about whether you’re a good candidate for treatment.

Consider factors like how comfortable you are with daily pills versus weekly injections, your insurance coverage, and your ability to follow the specific dosing requirements for oral medications. Your doctor can help you weigh these factors and choose the best option for your situation.

Remember that these medications work best as part of a comprehensive approach to health that includes healthy eating, regular physical activity, and ongoing medical care. If you’re ready to explore your options, learn how to order medications safely and affordably from UDS.
