Ozempic (semaglutide) is a GLP-1 receptor agonist approved for type 2 diabetes, but has become one of the most talked-about options for weight loss due to its appetite-curbing effects.
About 75% of Americans say they’ve heard of Ozempic and similar medications being used for this purpose. Among those taking GLP-1 drugs, nearly 4 in 10 report using them primarily to lose weight. Still, Ozempic isn’t the only option. If you’re looking for an FDA-approved weight loss medication, several other prescription options are available.
This guide breaks down the best weight loss drugs that work like Ozempic, what results to expect, and who they’re right for.
Weight Loss Drugs That Work Like Ozempic
When you’re on Ozempic, it’s common to feel less interested in food, which often leads to weight loss. But it isn’t FDA-approved for weight loss. Still, doctors might prescribe it off-label in some cases.
If you’re looking for medications like Ozempic that are specifically indicated for weight loss, here are some options to consider:
Active ingredients: Tirzepatide
Drug class: GIP and GLP-1 receptor agonist
Dosage form and strength: Prefilled, injectable pen and single-dose vial (2.5 mg, 5 mg, 7.5 mg, 10 mg, 12.5 mg, 15 mg)
Dosage frequency: Once weekly
Common side effects: Nausea, diarrhea, vomiting, constipation, abdominal pain, indigestion, injection site reactions, fatigue, hypersensitivity reactions, burping, hair loss, and acid reflux
Contraindications:
- Personal or family history of medullary thyroid carcinoma (MTC)
- Multiple Endocrine Neoplasia syndrome type 2 (MEN 2)
- Hypersensitivity to tirzepatide or any of the components of Zepbound
Pros:
Cons:
Zepbound is a relatively new medication for weight management. It gained FDA approval in 2023 and is indicated for adults who have obesity or are overweight with weight-related medical conditions. Zepbound is not yet approved for patients under age 18.
During a 17-month clinical trial, individuals were on a reduced-calorie diet, increased physical activity, and Zepbound. Average weight loss ranged from 34 to 48 lbs for non-diabetic adults and from 28 to 33 lbs for adults with diabetes, compared to 7 lbs for placebo.
Active ingredients: Semaglutide
Drug class: GLP-1 receptor agonist
Dosage form and strength: Prefilled, injectable pen (0.25 mg, 0.5 mg, 1 mg, 1.7 mg, 2.4 mg)
Dosage frequency: Once weekly
Common side effects: Headache, fatigue, dyspepsia, dizziness, abdominal distension, eructation, low blood sugar in patients with type 2 diabetes, flatulence, gastroenteritis, GERD, and nasopharyngitis
Contraindications:
- Personal or family history of medullary thyroid carcinoma (MTC)
- Multiple Endocrine Neoplasia syndrome type 2 (MEN 2)
- Hypersensitivity to semaglutide or any of the components of Wegovy
Pros:
Cons:
Wegovy has shown significant weight-loss benefits in studies. In a 68-week trial, users lost about 33 pounds on average, compared to 6 pounds with placebo. Among those with type 2 diabetes and obesity, Wegovy led to nearly 10% body weight loss versus just 3% in the placebo group.
Active ingredients: Liraglutide
Drug class: GLP-1 receptor agonist
Dosage form and strength: Prefilled, injectable pen (0.6 mg, 1.2 mg, 1.8 mg, 2.4 mg, 3 mg)
Dosage frequency: Once daily
Common side effects: Nausea, diarrhea, constipation, vomiting, injection site reactions, headache, low blood sugar, dyspepsia, fatigue, dizziness, abdominal pain, increased lipase, upper abdominal pain, pyrexia, and gastroenteritis
Contraindications:
- Personal or family history of medullary thyroid carcinoma (MTC)
- Multiple Endocrine Neoplasia syndrome type 2 (MEN 2)
- Hypersensitivity to liraglutide or any of the components of Saxenda
Pros:
Cons:
The first major phase 3 trial of Saxenda lasted 20 weeks and was compared to both placebo and orlistat. Across all doses, Saxenda led to significantly greater weight loss than placebo, with average losses ranging from 10.6 to 15.8 pounds depending on the dose.
In a separate 20-week trial with a two-year extension, Saxenda helped participants lose up to 12.8 pounds more than placebo. After two years, those on higher doses maintained an average 17.2-pound weight loss and saw a 15.4% reduction in body fat. Another 56-week study showed that Saxenda users lost an average of 17.6 pounds, compared to 5.7 pounds with placebo. The treatment also improved cardiovascular markers, blood glucose control, and overall quality of life.
Other Alternatives to Ozempic for Weight Loss
Here are more affordable alternatives to Ozempic for weight loss:
Active ingredients: Naltrexone-bupropion
Drug class: Anorexiant, combines an antidepressant (bupropion) and an opioid antagonist (naltrexone)
Dosage form and strength: Extended-release tablets (8 mg naltrexone/90 mg bupropion)
Dosage frequency: Up to 4 tablets per day
Common side effects: Nausea, constipation, headache, vomiting, dizziness, insomnia, dry mouth, and diarrhea
Contraindications:
- Poorly managed high blood pressure
- History of seizures or conditions causing seizures
- Use of other medications with bupropion
- Ongoing opioid treatment
- Recent use of monoamine oxidase inhibitors (within 14 days)
- Hypersensitivity to any of the components of Contrave
Pros:
Cons:
Bupropion curbs appetite and boosts metabolism by raising certain brain chemicals. But over time, your body can produce a signal that weakens this effect. Naltrexone blocks that signal, helping bupropion keep working to support weight loss.
In a real-world setting, people taking Contrave lost an average of 9.2% of their body weight within six months and 9.7% after a year, showing significantly better outcomes than those in the control group.
A systematic review also emphasized how this drug pair targets not just physical weight, but also psychological contributors to obesity. It showed promise in reducing behaviors like emotional or binge eating.
One particular study followed individuals with moderate to severe binge eating symptoms. By week 4, many began to notice improvements. At 24 weeks, 83% of participants reported minimal or no binge eating episodes. These changes were accompanied by better self-regulation, meaningful weight loss, improved mood, and even reductions in depression-related symptoms.
Active ingredients: Orlistat
Drug class: Lipase inhibitor
Dosage form and strength: Capsules (120 mg)
Dosage frequency: Taken 3 times a day
Common side effects: Oily spotting, passing gas with oily or greasy residue, sudden need to go to the bathroom, fatty/oily stool, needing to go to the bathroom more often, and trouble controlling bowel movements
Contraindications:
- Pregnancy
- Should not be used if the body cannot properly absorb nutrients
- Individuals with liver-related bile flow problems
- Hypersensitivity to any of the components of Xenical
Pros:
Cons:
Orlistat stops the body from absorbing some of the fat you eat. It blocks digestive enzymes responsible for breaking down fat, so about 30% of that fat passes through your system without being digested.
In a 24-week trial, people taking orlistat lost an average of 10.2 pounds. They also saw greater improvements in BMI and waist size compared to those on placebo, losing nearly 2 inches off their waistlines.
During one clinical trial for Xenical, users lost 11% of their body weight in the first year and kept off 6.9% over four years. They were also less likely to develop type 2 diabetes than those not taking the drug. In another study focused on people with type 2 diabetes, orlistat helped lower HbA1c levels after a year. It also led to more weight loss, 3.89% compared to just 1.27% in the placebo group.
Qsymia (phentermine-topiramate)

Active ingredients: Phentermine-topiramate
Drug class: Anorexiant, combines a stimulant (phentermine) and an anticonvulsant (topiramate)
Dosage form and strength: Extended-release capsules (3.75 mg/23 mg, 7.5 mg/46 mg, 11.25 mg/69 mg, 15 mg/92 mg)
Dosage frequency: Once daily
Common side effects: Tingling or numbness, dizziness, altered taste, insomnia, constipation, dry mouth, depression, joint pain, fever, flu, and stretched or torn ligament.
Contraindications:
- Pregnancy due to possible birth defects, such as clefts in the baby’s mouth or face
- People with hyperthyroidism or glaucoma
- Individuals who have used monoamine oxidase inhibitors in the past 14 days
- Hypersensitivity to any of the components of Qsymia
Pros:
Cons:
Qsymia combines phentermine and topiramate to help with weight loss. Phentermine curbs hunger by triggering brain chemicals that suppress appetite. Topiramate increases feelings of fullness, reduces cravings, and can even make some foods taste less appealing.
In a 20-week study, this combination led to a 4.1% drop in body weight, compared to 3.6% with phentermine alone. A meta-analysis also found phentermine-topiramate to be one of the most effective weight-loss drugs, with 75% of users losing at least 5% of their body weight. On average, people taking it lost 19.4 pounds over a year.
Tips for Safer & Effective Results While on Medications Similar to Ozempic
Here are some strategies you can apply day-to-day:
Final Thoughts
Drugs such as Zepbound, Wegovy, and Saxenda use similar GLP-1-based mechanisms to reduce appetite and support long-term weight loss. Others like Contrave, Qsymia, and Xenical work differently but still offer meaningful results.
Each option has its pros, side effects, and dosing differences. Some are weekly injections, others are daily pills. What they all share is the potential to support weight loss when combined with a healthy diet, regular activity, and medical supervision. These Ozempic alternatives for weight loss can be just as effective, depending on your needs.
