Once you’ve decided to take semaglutide, the next step is picking a format. Semaglutide comes in both oral and injectable forms. But they’re not interchangeable for every person or goal.
In this guide, we’ll compare oral and injectable semaglutide so you and your doctor can make an informed choice. At Maven Clinic, our expert clinicians will help you choose between oral and injectable forms based on your health history, goals, and stage of life.
Semaglutide pills vs. injections: How they compare
Semaglutide is an active ingredient in some medicines called GLP-1 receptor agonists (GLP-1 RAs). These medications mimic glucagon-like peptide-1 (GLP-1), a hormone your body naturally produces.
Several brand-name medicines contain semaglutide, including the following:
- Ozempic® is FDA-approved for type 2 diabetes care and heart and kidney risk reduction. It comes in oral and injectable forms.
- Wegovy® is FDA-approved for chronic weight management and heart and liver risks reduction. Like Ozempic, Wegovy comes in oral and injectable forms.
- Rybelsus® is FDA-approved for type 2 diabetes care and heart-related risk reduction. It only comes in pill form.
No matter which brand you choose, oral and injectable semaglutide have a few differences. Here’s a brief table highlighting each:

How oral and injectable semaglutide compare for weight loss
An article from the Expert Review of Endocrinology & Metabolism shows that people taking injectable semaglutide lose slightly more weight than those on oral medicines. After two years, people taking oral semaglutide lost an average of 8.7 pounds. Those using injectable semaglutide lost an average of 16.7 pounds during the same timeline.
One reason this might occur is bioavailability, or how much of the medication your body actually absorbs. Less than 1% of oral semaglutide makes it into your bloodstream, compared to around 89% of injectable semaglutide.
Because of that, you have to take oral semaglutide more often at higher doses than the injectable version. When used every day, oral semaglutide has a similar rate of exposure to injectable medication, but not at identical levels. This may explain why some people experience greater weight loss on injectable semaglutide.
Common side effects and safety considerations
Both oral and injectable semaglutide may cause side effects. But research suggests that people taking oral semaglutide experience side effects more often and are more likely to stop taking the medication due to adverse effects. Below are the following side effects listed on FDA medication labels, sorted by oral and injectable medications:
Side effects vary between brands and individuals. Read your medication label and talk to your doctor to learn about any other reactions you should watch for.
When to contact your healthcare team
Call your doctor immediately if you experience any of the following symptoms:
- Swelling in your neck or throat, issues swallowing or breathing, or raspy voice (all signs of potential thyroid tumors)
- Changes in vision, especially blurriness (could be a sign of diabetic retinopathy)
- Excess gas, heartburn, ongoing fever, stomach fullness, or yellow eyes or skin (all signs of potential gallbladder issues)
- Severe abdominal or back pain (could be a sign of pancreatitis)
- Allergic reactions like swelling, rashes, rapid heartbeat, or problems breathing
This list isn’t comprehensive. Any severe reaction warrants a call to your doctor.
Semaglutide tablets vs. injection: How to choose
Before starting GLP-1 RAs, consider:
- Administration preference: You may prefer to avoid injections and needles altogether. If oral semaglutide would help you feel comfortable, let your doctor know.
- Lifestyle: Oral semaglutide needs to be taken daily on an empty stomach with no other food or drink. If you’d have trouble managing this alongside your busy lifestyle, consider injections.
- Medical history: Each semaglutide interacts with preexisting health conditions and other medicines differently. Ask your doctor which is best for your situation.
- Side effects: People on oral semaglutide tend to experience more side effects, so if that’s a concern, injections may be a better option.
Cost and insurance considerations for semaglutide
Prices fluctuate depending on whether you’re paying with insurance or out of pocket. Semaglutide prices can drop as low as $25 per month with coverage, but they rise to $350 (or more) without.
Dosage also plays a role. At early, lower-dose treatment stages, oral semaglutide may cost less out of pocket than injectable forms. But at later, higher-dose stages, out-of-pocket costs rise for oral medicines.
To find out more about costs, reach out to your pharmacist and insurance company.

FAQ
What are the disadvantages of oral semaglutide?
Even taken daily, oral semaglutide may still deliver less of the drug to your system than injectable versions (though the difference is slight). Patients taking oral semaglutide also tend to experience more side effects and are likelier to stop taking the prescription altogether.
Does oral semaglutide work immediately?
Oral semaglutide reaches its maximum level in your bloodstream after a dose (peak concentration) within about one hour after taking it. However, you may only start to notice its effects after a few weeks or months.
Which is better, a GLP-1 RA shot or a pill?
It mostly comes down to personal preference. Oral GLP-1 RAs may suit your preference to avoid needles, while injectable versions may work best if you don’t want to remember a daily pill. Your physician will consider all of this to help guide your decision.
Does semaglutide get rid of belly fat?
Semaglutide may help you reduce body fat, including belly fat. A meta-analysis found that people taking GLP-1 RAs (including semaglutide) lose an average of 11% of their starting weight.
What foods should you avoid while taking semaglutide?
If you’re using semaglutide for weight management, avoid spicy and greasy meals, as they might worsen side effects. Ask your doctor for a full list of foods to avoid while on this medicine.
