Weight loss shots include several medical options, each with a different active ingredient and prescribed purpose. If you are wondering what are the names of the weight loss shots, you are likely looking for a clear breakdown of injectable medications that help manage body weight.
These injections are not magic. They work by affecting appetite, digestion, or metabolism. Some are FDA-approved for weight loss. Others are used off-label. Knowing the names helps you talk to your doctor.
Below is a complete guide. It covers brand names, generic names, and how each shot works. Let’s start with the most popular options.
What Are The Names Of The Weight Loss Shots
This section lists the main injectable medications for weight loss. Each name is a brand or generic term you might hear at a clinic or pharmacy.
Semaglutide Injections
Semaglutide is a GLP-1 receptor agonist. It mimics a hormone that tells your brain you are full. It also slows stomach emptying.
- Wegovy – FDA-approved specifically for weight management.
- Ozempic – Approved for type 2 diabetes, but often prescribed off-label for weight loss.
- Rybelsus – Oral tablet form, not a shot. Included for context.
Wegovy is the most common name for weight loss shots containing semaglutide. Ozempic is the same drug but marketed for diabetes.
Liraglutide Injections
Liraglutide is another GLP-1 agonist. It works similarly to semaglutide but requires daily injections.
- Saxenda – Approved for weight loss in adults and adolescents.
- Victoza – Approved for diabetes, used off-label for weight loss.
Saxenda is the primary brand for weight loss. Victoza is sometimes used, but it is not officially for weight management.
Tirzepatide Injections
Tirzepatide is a dual GIP and GLP-1 receptor agonist. It targets two hormones to reduce appetite and improve blood sugar.
- Mounjaro – Approved for diabetes, widely used off-label for weight loss.
- Zepbound – FDA-approved for weight management as of late 2023.
Zepbound is the newest name in weight loss shots. Mounjaro remains popular for its strong results.
Other Injectable Options
Some shots are less common but still prescribed. They include:
- Contrave – Actually an oral medication, not a shot. Misleading name.
- B12 Injections – Sometimes used for energy, not directly for weight loss.
- HCG Injections – Human chorionic gonadotropin, used in very low-calorie diets. Controversial and not FDA-approved for weight loss.
- Phentermine Injections – Rarely given as a shot. Usually oral.
These are not first-line treatments. Always check with a doctor before trying them.
How Do These Weight Loss Shots Work
Understanding the mechanism helps you choose the right option. Each shot targets different biological pathways.
GLP-1 Agonists
GLP-1 stands for glucagon-like peptide-1. These drugs mimic a natural hormone that:
- Increases insulin release after eating.
- Slows gastric emptying.
- Reduces appetite signals in the brain.
Semaglutide and liraglutide are GLP-1 agonists. They help you feel full longer and eat less.
Dual Agonists
Tirzepatide activates both GLP-1 and GIP receptors. GIP is glucose-dependent insulinotropic polypeptide. This dual action may lead to greater weight loss than single agonists.
Studies show tirzepatide can produce 15–20% body weight reduction. That is higher than semaglutide’s 10–15%.
Other Mechanisms
B12 shots boost metabolism slightly. HCG is thought to reduce hunger during severe calorie restriction. But evidence for these is weak.
Stick to FDA-approved options for reliable results.
Who Can Use These Shots
Not everyone qualifies. Doctors set criteria based on BMI and health conditions.
Eligibility Criteria
- BMI of 30 or higher (obesity).
- BMI of 27 or higher with at least one weight-related condition (high blood pressure, type 2 diabetes, high cholesterol).
- Failed previous weight loss attempts with diet and exercise.
You also need to commit to lifestyle changes. Shots alone are not enough.
Contraindications
Avoid these shots if you have:
- Personal or family history of medullary thyroid carcinoma.
- Multiple endocrine neoplasia syndrome type 2.
- Severe gastrointestinal disease (gastroparesis).
- Pregnancy or breastfeeding.
Always disclose your full medical history.
Dosage And Administration
Shots come in pens or vials. You inject them under the skin (subcutaneous). Common sites are the abdomen, thigh, or upper arm.
Typical Dosing Schedule
Most GLP-1 drugs start low and increase gradually.
- Wegovy: Weekly injection. Start at 0.25 mg, increase every 4 weeks to 2.4 mg.
- Saxenda: Daily injection. Start at 0.6 mg, increase weekly to 3.0 mg.
- Zepbound: Weekly injection. Start at 2.5 mg, increase to 15 mg over several months.
Follow your doctor’s instructions exactly. Do not skip doses or double up.
How To Inject
- Wash your hands.
- Clean the injection site with alcohol.
- Pinch the skin.
- Insert the needle at a 90-degree angle.
- Press the plunger slowly.
- Hold for 5 seconds, then remove.
Rotate injection sites to prevent lumps or skin reactions.
Side Effects And Risks
Weight loss shots have side effects. Most are mild and temporary.

These usually improve within weeks. Eating smaller meals and avoiding fatty foods can help.

Lifestyle changes are crucial for lasting results.
Comparing Popular Shots
Here is a quick comparison of the top options.
Wegovy Vs Ozempic
Both contain semaglutide. Wegovy is approved for weight loss. Ozempic is for diabetes. Doses differ: Wegovy goes up to 2.4 mg, Ozempic to 1.0 mg.
Doctors sometimes prescribe Ozempic off-label for weight loss. But Wegovy is the intended choice.
Saxenda Vs Wegovy
Saxenda is daily; Wegovy is weekly. Wegovy tends to produce more weight loss. Saxenda may have fewer side effects for some.
Choose based on your schedule and tolerance.
Zepbound Vs Mounjaro
Same drug, different labels. Zepbound is for weight loss. Mounjaro is for diabetes. Both are weekly injections.
Zepbound is newer and specifically approved for weight management.
