are now available as a pill for weight loss, offering another option beyond injections. Like the injections, GLP-1 pills can help regulate your appetite, reduce food cravings, and make it easier to feel full with less food.

Taking a pill may feel simpler than giving yourself injections. But GLP-1 pills come with their own considerations, including how they’re taken each day. They also work best if you combine them with healthy habits, such as eating a balanced diet and exercising regularly.

If you’re thinking about a GLP-1 pill for weight loss, it’s a good idea to understand how they work and whether they fit into your lifestyle and health needs. shares eight things to know before you get started.

Key takeaways:

• Glucagon-like peptide-1 (GLP-1) pills offer a needle-free alternative to injections for weight loss. The Wegovy pill (oral semaglutide) is currently available. Orforglipron, another GLP-1 pill, may be available soon.
• GLP-1 pills need to be taken carefully every day to maximize absorption. For Wegovy pills, this includes taking your dose first thing in the morning on an empty stomach, with only a small amount of water.
• GLP-1 pills may be a good fit if you want to avoid needles and can stick to a daily routine. A healthcare professional can help determine whether they are the best option for you.

1. GLP-1 pills work similarly to injections, but their absorption is different

Like GLP-1 injections, GLP-1 pills mimicking the effects of GLP-1, a natural gut hormone that helps regulate appetite, fullness, and digestion. These effects can make it easier to eat less and support weight loss.

The biggest difference between the is their absorption route and how much is absorbed. Because of this, the dosage schedule, timing, and factors that influence how well the medication works can vary between the two forms.

• How they’re absorbed: GLP-1 injections release the medication into the fatty layer under the skin, where it’s absorbed into the bloodstream. GLP-1 pills, on the other hand, are taken by mouth and must pass through the digestive system before they can be absorbed.
• How much is absorbed: When semaglutide () is injected, most of the dose enters the bloodstream. But when it’s taken by mouth, only a small amount is absorbed. That’s because semaglutide is a peptide, a type of that can be broken down in the gut. For this reason, semaglutide pills need to be taken every day exactly as directed to maximize absorption (more on this later).

is another daily GLP-1 pill that . Unlike semaglutide, it’s not a peptide, which makes it more stable in the stomach and easier for the gut to absorb.

2. Weight loss can be meaningful, but results can vary from person to person

Many people with GLP-1 pills, while others see more modest changes. For example, people taking the Wegovy pill lost an average of of their starting body weight during clinical trials (similar to Wegovy injections).

That said, not everyone responds the same way to GLP-1s. Factors such as how consistently you take the medication, your lifestyle habits, and your individual biology can all influence how much weight you may lose. Some people respond quickly, while others lose weight more gradually. A small percentage, though, .

If you’re starting a GLP-1 pill, it helps to set realistic expectations and track your progress over time, rather than focusing on week-to-week changes. Your prescriber can help you understand whether the medication is working for you, or if adjustments may be needed.

3. GLP-1 pills must be taken carefully

Some GLP-1 pills come with strict dosage instructions to help the medication work as intended. This is especially true for oral semaglutide, which must be on an empty stomach, with a small amount of water. You’ll also need to wait 30 minutes before eating, drinking, or taking other oral medications.

This may be less of an issue with orforglipron. Because it’s absorbed better in the gut, it’s expected to have fewer timing and fasting requirements. However, dosage instructions still matter, and final guidance will depend on FDA approval and labeling.

If strict timing rules are difficult to follow, a healthcare professional can help you decide whether a pill or injection is a better option.

4. Expect side effects, especially at first and after dose changes

When starting a GLP-1 pill, your body often needs time to adjust, which is why you’ll start with a low dose that’s slowly increased over time. are most likely to occur early in treatment or after a dose increase. Side effects are less likely when you’ve been stable on a dose for a while.

• (blood sugar), especially if taken with certain diabetes medications.
• Severe allergic reactions, including .
• A potential increased risk of thyroid C-cell tumors (based on animal studies, and has not been confirmed in people).

5. Not everyone is a good candidate for GLP-1 pills

GLP-1 pills offer a needle-free option, but they’re not appropriate for everyone. You may be advised to if you:

• Have a personal or family history of .
• Have .
• Have a history of pancreatitis.
• Have severe gastrointestinal problems, such as (slowed stomach emptying).
• Are allergic to any in the medication.
• Are pregnant or breastfeeding.

Other reasons GLP-1 pills may not be the best fit for you include:

• You have difficulty remembering to take medications every day.

A healthcare professional can help you sort through these factors and decide whether a GLP-1 pill is right for you. If not, they can also suggest for weight loss.

6. Medication is only part of the plan

GLP-1 pills can help make it easier to lose weight. But they don’t replace the habits that support long-term health. Because they affect appetite and digestion, how you eat, move, and care for your body still plays an important role in both results and side effects.

• Diet and hydration: Focus on eating smaller , prioritizing , and . It’s also best to limit fatty or heavy meals. This can help support weight loss while reducing side effects such as nausea.

Some people start with a GLP-1 injection and later to help maintain weight loss. Others may and move to injections. A switch may make sense if your preferences change, side effects are hard to manage, or cost or access becomes an issue.

Because GLP-1 pills and injections are absorbed differently, switching isn’t a one-to-one change. A healthcare professional can help adjust your dose and timing to make the transition as smooth and effective as possible.
