Here's what we'll cover

GLP-1 medications are no longer just diabetes drugs, they’re now some of the most widely discussed treatments in metabolic health and weight management. Ozempic, Trulicity, Victoza, and newer agents like Mounjaro and Zepbound all work by mimicking gut hormones that regulate appetite, insulin release, digestion, and blood sugar levels.

While these medications share a common mechanism, they differ significantly in how often you take them, who qualifies, their side effect profiles, their benefits, and how much weight loss you can expect. With more GLP-1 drugs entering the market every year, choosing the right option can feel overwhelming.

1. Ozempic (semaglutide)

Ozempic is a once-weekly injectable GLP-1 medication approved for adults with Type 2 diabetes. It comes in a multi-dose pen and can be taken any time of day as long as you use it on the same day each week.

Your clinician may prescribe Ozempic if you have:

   • Type 2 diabetes with heart disease, to reduce major heart-related risks

   • Chronic kidney disease, to help slow the progression toward kidney failure

   • Excess weight — even though it’s not officially approved for weight loss, many people lose weight while taking it

On average, participants in earlier trials lost 8–10 lbs by week 30, though weight loss varies by dose.

Semaglutide continues to be studied for additional conditions, and more indications may be approved in the future.

2. Rybelsus (oral semaglutide)

Oral semaglutide is available in two forms: Rybelsus (approved for type 2 diabetes) and oral Wegovy (approved for weight loss), both taken once daily. It’s taken once daily, first thing in the morning, with a small amount of water. You must wait 30 minutes before eating or drinking so your body can absorb it properly.

Important notes:

   • It is approved only for Type 2 diabetes, not weight loss

   • Switching between Ozempic and Rybelsus is possible, but not ideal at higher Ozempic doses

3. Wegovy (higher-dose semaglutide)

Wegovy is a once-weekly semaglutide injection approved for weight loss, not diabetes.

You may qualify if you are:

   • An adult or adolescent (12+) with obesity

   • An adult with overweight and a related health condition (high blood pressure, diabetes, high cholesterol, etc.)

Clinical trials show:

    • Adults lose ~15% of their starting weight
   • Teens lose ~15% of their starting BMI

Wegovy also has FDA approval for:

   • Reducing major cardiovascular events in people with obesity and heart disease

   • Treating MASH (metabolic dysfunction–associated steatohepatitis) with moderate–advanced fibrosis

4. Trulicity (dulaglutide)

Trulicity is a once-weekly injection for Type 2 diabetes, approved for adults and children 10+. It comes as an easy-to-use single-dose pen.

Trulicity can:

   • Reduce cardiovascular risks in adults with diabetes

   • Help support kidney health

Weight loss is not its primary purpose, but some people lose weight, especially at the higher 4.5 mg dose.

5. Victoza (liraglutide)

Victoza is a once-daily GLP-1 injection approved for Type 2 diabetes in adults and children 10+. It may reduce the risk of heart attack and stroke in those with diabetes and heart disease.

Typical weight loss is mild (around 5 lbs). For weight loss–specific treatment, Saxenda (a higher-dose version of liraglutide) is available.

A key advantage: a generic version of liraglutide is available, which may provide a more affordable GLP-1 option. Note that branded Victoza has experienced supply shortages since July 2023; patients seeking liraglutide should confirm current availability with their pharmacy and may be directed to the generic formulation.

6. Saxenda (liraglutide for weight loss)

Saxenda is the weight-loss version of liraglutide. It is approved for adults and adolescents 12+ with obesity, or adults with overweight plus a related condition.

Clinical results show:

   • Adults lost ~8% of body weight

   • Teens lost ~2.5% of body weight

But Saxenda requires daily injections, which some people find less convenient than weekly options.

Compared head-to-head, Wegovy leads to significantly greater weight loss (16% vs. ~6%).

7. Mounjaro (tirzepatide)

Mounjaro is not a pure GLP-1. It belongs to a newer class: GIP/GLP-1 dual agonists, mimicking two gut hormones instead of one.

Mounjaro is approved for Type 2 diabetes and has shown superior results compared to Ozempic in head-to-head trials:

   • Greater A1C reduction

   • More weight loss

It is also being studied for cardiovascular protection, though it is not approved for that purpose yet.

8. Zepbound (tirzepatide for weight loss)

Zepbound is the FDA-approved weight-loss version of tirzepatide.

You may qualify if you are:

    • An adult with obesity
   • An adult with overweight and a related condition

Zepbound is also approved for obstructive sleep apnea in people with obesity.

Clinical trials show dramatic results:

   • Up to 21% weight loss over 72 weeks

This is currently among the highest weight-loss outcomes for any obesity medication on the market.

Important Safety Information:

GLP-1 medications are not appropriate for everyone. These medications should not be used by people with a personal or family history of medullary thyroid carcinoma (MTC) or Multiple Endocrine Neoplasia syndrome type 2 (MEN2). They should be used with caution in people with a history of pancreatitis. Always consult a licensed healthcare provider to determine whether a GLP-1 medication is appropriate for your medical history before starting treatment.

How to Choose the Right GLP-1 Medication

Your best option depends on your goals:

For weight loss → consider:

    • Wegovy
   • Zepbound
   • Saxenda (daily injection, less effective)

For Type 2 diabetes → consider:

    • Ozempic
   • Trulicity
   • Rybelsus
   • Victoza
   • Mounjaro

For affordability → consider:

    • Generic liraglutide (Victoza)

For the most weight loss overall → Zepbound or Wegovy

The Bottom Line

The GLP-1 landscape is expanding rapidly, giving people more choices than ever before. While these drugs share a common foundation, they differ in dosing frequency, effectiveness, approvals, and cost.

Choosing the right medication comes down to:

    • Your medical conditions
   • Your weight-loss goals
   • Your insurance coverage
   • Your tolerance for injections
   • How aggressive you want your treatment to be

A healthcare provider can help match you with the safest and most effective option based on your unique needs.
