FDA-Approved Weight Loss Medications: Quick Comparison

*Costs are approximate without insurance and vary by pharmacy and dose.

The Most Effective: GLP-1 Medications

GLP-1 (glucagon-like peptide-1) medications have revolutionized weight loss treatment. These drugs mimic a natural gut hormone that regulates appetite, slows stomach emptying, and helps control blood sugar. Clinical trials consistently show weight loss of 15–22% or more with GLP-1 drugs, compared to 5–10% with other medications.

Zepbound (Tirzepatide) — Most Effective Overall

Weight Loss: 21–22.5% average body weight loss

How Taken: Once-weekly subcutaneous injection

FDA Approved: November 2023 for weight management

Cost: ~$1,000+/month without insurance

Zepbound is currently the most effective FDA-approved weight loss medication. It’s a dual GIP/GLP-1 receptor agonist, meaning it activates two hormone pathways instead of just one. This dual action appears to produce superior weight loss compared to single GLP-1 drugs. Clinical trials show that people taking Zepbound lost up to 22.5% of their body weight—for a 230-pound person, that’s 50 pounds on average.

Common side effects: Nausea, diarrhea, constipation, vomiting (usually mild and temporary)

Best for: People seeking maximum weight loss results who can tolerate injections and can access/afford the medication

Semaglutide Injection (Wegovy) — Highly Effective & Cardiovascular Benefits

Weight Loss: 15–16% average body weight loss

How Taken: Once-weekly injection

FDA Approved: 2021 for weight management

Cost: ~$1,300+/month without insurance

Wegovy was the first semaglutide product approved specifically for weight loss and has been widely used since 2021. It’s a GLP-1 receptor agonist that produces significant weight loss over 68 weeks of treatment.

A major advantage of Wegovy: it reduces cardiovascular risk in people with obesity and heart disease. The SELECT trial demonstrated a 20% reduction in major cardiovascular events (heart attack, stroke, and cardiovascular death), making it particularly valuable for people with both obesity and existing heart disease.

Common side effects: Nausea, diarrhea, constipation, vomiting, abdominal pain (usually temporary)

Best for: People wanting highly effective weight loss with proven cardiovascular benefits, or those with existing heart disease

Oral Semaglutide (Wegovy Pill) — NEW in 2026

Weight Loss: 13–14% average body weight loss

How Taken: Once daily on an empty stomach with a small sip of water (must wait 30 minutes before eating)

FDA Approved: December 2025

Cost: $149–1,350+/month depending on dose and source

In December 2025, the FDA approved the first oral GLP-1 for weight loss—a game-changer for people who don’t want to use injections. The OASIS 4 trial showed the pill produces 13.6% average weight loss, nearly matching the injectable version’s effectiveness without needles.

Novo Nordisk announced starting prices at $149/month for self-pay patients on the lowest dose, though higher maintenance doses cost significantly more. This pill must be taken on an empty stomach with a maximum of 4 ounces of water, and you must wait 30 minutes before eating or drinking anything else.

Main drawback: Must be taken on empty stomach; slightly less effective than injection

Best for: People who want GLP-1 drugs comparison therapy but prefer daily pills over weekly injections

Liraglutide (Saxenda) — Older GLP-1 Option

Weight Loss: 5–8% average body weight loss

How Taken: Once-daily subcutaneous injection

FDA Approved: 2014 for weight management

Cost: $200–500/month (available as generic)

Saxenda was the first GLP-1 approved for weight loss and is now available as a generic, making it more affordable than newer options. While effective, it produces less weight loss than semaglutide or tirzepatide because it’s a single GLP-1 agonist (not dual) and requires daily injections versus weekly dosing.

Because of daily dosing requirements and lower effectiveness, most providers now prefer Wegovy or Zepbound when GLP-1 therapy is appropriate.

Common side effects: Nausea, diarrhea, constipation (similar to other GLP-1s)

Best for: Budget-conscious patients who want a GLP-1 but can’t afford newer options, or those whose insurance specifically covers Saxenda

Non-GLP-1 Weight Loss Medications

While GLP-1 drugs dominate in terms of effectiveness, three other FDA-approved medications offer alternatives—especially for people who can’t tolerate GLP-1 side effects, don’t want injections, or need more affordable options.

Phentermine-Topiramate (Qsymia) — Most Effective Non-GLP-1

Weight Loss: 7–10% average body weight loss

How Taken: Once-daily pill

FDA Approved: 2012 for weight management

Cost: ~$100–200/month without insurance

Qsymia combines phentermine (an appetite suppressant) and topiramate (an anti-seizure medication that also reduces appetite). It’s one of the more effective non-GLP-1 options, producing 7–10% weight loss on average—comparable to some GLP-1 options when cost and pill form are considerations.

Important warnings: Qsymia has several restrictions. It cannot be used during pregnancy as it causes birth defects, and women of childbearing age must use reliable contraception. It’s also not appropriate for people with glaucoma, hyperthyroidism, or cardiovascular disease, as the phentermine component can increase heart rate and blood pressure.

Common side effects: Tingling sensations in hands and feet, dry mouth, constipation, insomnia, dizziness, taste changes

Best for: People seeking an effective oral option who can’t access or tolerate GLP-1 drugs, with no cardiovascular disease or pregnancy plans

Naltrexone-Bupropion (Contrave) — Targets Cravings

Weight Loss: 5–6% average body weight loss

How Taken: Twice-daily pill (dose increases over 4 weeks)

FDA Approved: 2014 for weight management

Cost: ~$50–200/month without insurance

Contrave combines naltrexone (used to treat addiction) and bupropion (an antidepressant). It works on the brain’s reward system to reduce cravings and appetite, offering a different mechanism than GLP-1 drugs.

Important warnings: Contrave carries a boxed warning for increased risk of suicidal thoughts and behaviors (due to the bupropion component). It cannot be used by people with uncontrolled high blood pressure, seizure disorders, eating disorders, or those taking opioids. It also interacts with many medications.

Common side effects: Nausea, headache, constipation, dizziness, insomnia, dry mouth

Best for: People who struggle with food cravings and emotional eating; may also help with depression symptoms; seeking a more affordable oral medication

Orlistat (Xenical/Alli) — Only OTC Option

Weight Loss: 3–5% average body weight loss

How Taken: Three times daily with meals containing fat

FDA Approved: 1999 (Xenical); 2007 (Alli over-the-counter)

Cost: ~$30–100/month; Alli available OTC

Orlistat works completely differently than other weight loss medications—it blocks your body from absorbing about 25% of the fat you eat. Alli is the over-the-counter version (60mg) available without prescription; Xenical is the prescription-strength version (120mg).

The mechanism means that eating high-fat meals while taking orlistat causes uncomfortable GI side effects—oily stools, urgency, gas with discharge. These side effects essentially enforce a low-fat diet, which is part of how the medication works.

Common side effects: Oily spotting, gas with discharge, urgent bowel movements, oily stools (especially with high-fat meals); can block absorption of fat-soluble vitamins

Best for: Budget-conscious individuals committed to a low-fat diet, or those wanting to try OTC weight loss medication before prescription options

The 2026 Game-Changer: Oral Wegovy Pill

January 2026 marked a turning point in weight loss treatment. The FDA approved oral semaglutide 25mg (Wegovy pill), the first oral GLP-1 medication for weight management. This is significant because previous GLP-1 drugs required injections, which many people found inconvenient or uncomfortable.

The pill produces 13.6% average weight loss over 64 weeks—nearly matching the injectable version’s 15% average. You get comparable effectiveness with daily pill dosing instead of weekly injections. The key requirement: the pill must be taken on an empty stomach with 4 ounces of water maximum, and you must wait 30 minutes before eating or drinking anything else.

Having a pill option may improve insurance coverage over time, as some plans have been more willing to cover oral medications than injectables.

Upcoming Weight Loss Medications to Watch in 2026

The weight loss medication landscape continues to evolve. Here are promising options in development:

Orforglipron (Expected: Spring 2026)

Eli Lilly’s oral GLP-1 that doesn’t require dietary restrictions. Unlike oral Wegovy (which must be taken on an empty stomach), orforglipron can be taken with or without food. Clinical trials showed about 12.4% weight loss. FDA decision expected in spring 2026, which could provide additional oral options and potentially drive costs down through competition.

Retatrutide (In Late-Stage Trials)

Eli Lilly’s “triple agonist” that targets three hormones (GLP-1, GIP, and glucagon). Early trials showed remarkable results—up to 28.7% weight loss at 68 weeks. Seven Phase 3 trials are underway, with results expected in late 2025 or early 2026.

CagriSema (In Development)

Novo Nordisk’s combination of semaglutide plus cagrilintide (an amylin analog). Phase 3 results showed 20.4% weight loss, with nearly 1 in 5 participants losing 30% or more of their body weight.

Important Truths About Weight Loss Medications

They’re Not Magic Pills

Every FDA-approved weight loss medication is designed to be used alongside reduced-calorie diet and increased physical activity—not instead of lifestyle changes. The medications make lifestyle changes more achievable by reducing appetite and cravings, but they don’t replace the need for healthy habits.

Long-Term Use Is Usually Necessary

Clinical trials consistently show that most people regain a significant portion of lost weight after stopping medication. Obesity is a chronic condition, and these medications are generally intended for long-term use. Studies show that when people stop taking weight loss medications, they often regain weight because the medications work by changing appetite signals—and those signals return to normal when you stop.

Individual Results Vary Widely

The percentages cited are averages from clinical trials. Some people lose much more, some lose less, and some don’t respond as well. Genetics, metabolism, lifestyle adherence, starting weight, and other factors all influence results.

Insurance Coverage Is Complicated

Many insurance plans don’t cover weight loss medications, viewing them as “cosmetic” rather than medical treatment (despite obesity being a recognized disease). Some plans cover them only for people with BMI ≥30 (or ≥27 with weight-related conditions). Some cover certain medications but not others. Medicare currently does not cover most weight loss medications, though this may change. Check your specific plan’s formulary and prior authorization requirements before starting treatment.

How to Choose the Right Weight Loss Medication

With six FDA-approved options (plus new oral formulations), choosing the right medication depends on multiple factors beyond just effectiveness.

Weight Loss Goals: If you need to lose 20%+ of body weight, GLP-1 drugs (especially Zepbound or injectable Wegovy) are most likely to get you there. For more modest goals (10–15%), non-GLP-1 options or oral Wegovy may suffice.

Administration Preference: Hate needles? Consider oral Wegovy (available 2026), Qsymia, Contrave, or Alli. Don’t mind injections and want maximum effectiveness? Zepbound or injectable Wegovy offer superior results.

Budget and Insurance: GLP-1 drugs cost $1,000+ monthly without insurance. Qsymia (~$100–200), Contrave (~$50–200), and Alli (~$30–100 OTC) are much more affordable. Check your insurance formulary—coverage varies significantly by plan.

Medical Conditions: Have type 2 diabetes? GLP-1 drugs help blood sugar too. Heart disease? Wegovy has proven cardiovascular benefits (20% reduction in cardiovascular events per SELECT trial). Cardiovascular issues make Qsymia inappropriate. History of depression or eating disorders? Contrave may not be suitable.

Side Effect Tolerance: If you’re sensitive to nausea, the GI side effects of GLP-1 drugs might be challenging initially (though they usually improve). If you can commit to a low-fat diet, orlistat’s side effects are manageable. If tingling or taste changes concern you, avoid Qsymia.

Your healthcare provider will consider your complete medical history, current medications, and personal circumstances when recommending treatment. There’s no universally “best” medication—just the best one for your specific situation.

Frequently Asked Questions

The Bottom Line

We’re living in an exciting time for weight loss treatment. GLP-1 medications like Zepbound and Wegovy offer unprecedented effectiveness, and the 2026 approval of oral Wegovy is a game-changer for people who want GLP-1 efficacy without injections. More affordable options like Qsymia and Contrave provide solid results for people who can’t access or tolerate GLP-1 therapy.

The key takeaway: no medication works alone. All FDA-approved weight loss drugs are designed to be used alongside reduced-calorie diet and increased physical activity. They’re tools that make lifestyle changes more achievable, not replacements for healthy habits. Combined with commitment to healthy eating and physical activity, these medications can help millions of people achieve weight loss that wasn’t possible before.

Work closely with your healthcare provider to choose the right medication for your medical history, goals, budget, and lifestyle—and commit to the comprehensive approach needed for lasting success.
