Best Weight Loss Injection Pens

Obesity continues to be a pressing health concern, affecting millions of individuals worldwide. Despite numerous diets, exercise plans, and weight loss supplements available, many still struggle to achieve and maintain a healthy weight. In 2022, over 1 billion individuals globally were living with obesity, a figure that has more than doubled since 1990. This increase has been seen across all age groups, with particularly alarming rates among children and adolescents.

This alarming trend not only impacts overall health but also increases the risk of chronic diseases such as diabetes, heart disease, and certain cancers. To address this growing epidemic, new and innovative weight loss solutions are essential.

One promising option that has gained significant attention is the use of FDA-approved weight loss pens. These pen injections offer a convenient and effective way to manage weight when used alongside a healthy diet and regular exercise. In this article, we will review the top weight loss pens on the market, highlighting their benefits and providing tips on how to use them for the best results.

Top Weight Loss Pens

Here are the top FDA-approved weight loss pens that assist individuals in managing their weight effectively when combined with a healthy diet and regular exercise.

Ingredients and Their Effectiveness

Zepbound’s active ingredient is tirzepatide, a dual glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1) receptor agonist. It mimics the actions of these endogenous incretin hormones, which play a crucial role in regulating glucose metabolism.

GLP-1 receptor agonists aid in promoting weight loss by slowing stomach emptying, which helps individuals feel full more quickly and reduces appetite. These agonists function by acting on receptors located in both the gut and brain. When GLP-1 reaches the arcuate nucleus in the brain, it activates neurons responsible for controlling hunger and promoting satiety, while also indirectly suppressing neurons that stimulate appetite.

GIP, another hormone produced in the small intestine, binds to receptors in various parts of the body, including the pancreas, fat tissue, heart, and brain. GIP helps with weight loss by enhancing the feeling of fullness, especially in the hypothalamus, a brain area that regulates hunger.

Studies have shown that the combination of these two hormones can lead to greater weight loss compared to using each one alone.

Clinical Studies

Across the SURMOUNT trials, Zepbound consistently led to weight reduction in individuals with obesity, regardless of their initial BMI, compared to placebo.

1. Tirzepatide once weekly for the treatment of obesity (SURMOUNT-1), published in The New England Journal of Medicine (2022)

At the start of the study, participants had a mean body weight of 104.8 kg (231 lbs) and a mean BMI of 38.0, with 94.5% having a BMI of 30 or higher. At week 72, the mean percentage weight loss was 3.1% for the placebo group, 15.0% for the 5 mg group, 19.5% for the 10 mg group, and 20.9% for the 15 mg group.

The percentage of participants achieving at least 5% weight loss was 35% in the placebo group, and 85%, 89%, and 91% in the 5 mg, 10 mg, and 15 mg tirzepatide groups, respectively. Additionally, 50% and 57% of participants in the 10 mg and 15 mg groups, respectively, achieved a weight reduction of 20% or more, compared to just 3% in the placebo group.

2. Tirzepatide once weekly for the treatment of obesity in people with type 2 diabetes (SURMOUNT-2), published in The Lancet (2023)

The average body weight at the start was 100.7 kg (221.9 lbs), with an average BMI of 36.1 kg/m². By week 72, participants who took tirzepatide experienced significant weight loss. Those on the 10 mg dose lost about 12.8% of their body weight, while those on the 15 mg dose lost about 14.7% of their body weight. In contrast, participants who received the placebo only lost about 3.2% of their body weight. Furthermore, 79-83% of participants treated with tirzepatide achieved a weight reduction of 5% or more, compared to 32% in the placebo group.

3. Tirzepatide after intensive lifestyle intervention in adults with overweight or obesity (SURMOUNT-3), published in Nature Medicine (2023)

This study included obese adults with at least one obesity-related complication (excluding diabetes) who had already achieved a weight loss of 5% or more after a 12-week intensive lifestyle intervention. They were then randomly assigned to receive either the maximum tolerated dose of tirzepatide (10 or 15 mg) or a placebo.

By week 72, those on tirzepatide lost an additional 18.4% of their body weight, while those on the placebo gained 2.5% of their body weight. Furthermore, 87.5% of participants taking tirzepatide achieved an additional weight reduction of 5% or more, compared to only 16.5% of those on the placebo.

4. Continued treatment with tirzepatide for maintenance of weight reduction in adults with obesity (SURMOUNT-4), published in JAMA Network (2023)

This phase 3 study evaluated tirzepatide’s effect on maintaining weight reduction with diet and exercise. During a 36-week open-label period, 783 participants received the maximum tolerated dose of tirzepatide (10 or 15 mg) weekly. At week 36, participants were randomized to continue tirzepatide or switch to a placebo.

Participants who completed the 36-week lead-in period experienced a mean weight reduction of 20.9%. From week 36 to week 88, the mean weight change was -5.5% for those continuing on tirzepatide, compared to a 14.0% weight gain for those switched to placebo. Overall, 89.5% of participants on tirzepatide maintained at least 80% of their initial weight loss, compared to 16.6% on placebo. The total mean weight reduction from the start to week 88 was 25.3% for tirzepatide and 9.9% for placebo.

Possible Side Effects and Safety Considerations

Zepbound is also contraindicated in individuals with a personal or family history of medullary thyroid carcinoma or those diagnosed with Multiple Endocrine Neoplasia syndrome type 2 (MEN 2). Additionally, it should not be used by patients who have known serious hypersensitivity to tirzepatide or any of the excipients present in Zepbound.

Clinical Studies

The STEP program evaluated the efficacy and safety of Wegovy in a broad population. Here are the findings:

1. Once-weekly semaglutide in adults with overweight or obesity (STEP 1), published in The New England Journal of Medicine (2021)

In this 68-week study, participants were treated with 2.4 mg Wegovy or placebo alongside lifestyle intervention. The results indicated a significant weight loss in the semaglutide group, with an average reduction of 14.9% in body weight compared to 2.4% in the placebo group. Specifically, 86.4% of those in the semaglutide group achieved at least a 5% weight reduction, compared to 31.5% in the placebo group. Moreover, 69.1% of the semaglutide group lost 10% or more of their body weight, and 50.5% lost 15% or more, compared to 12.0% and 4.9% in the placebo group, respectively.

2. Semaglutide 2·4 mg once a week in adults with overweight or obesity, and type 2 diabetes (STEP 2), published in The Lancet (2021)

The results of this study demonstrated that participants receiving semaglutide 2.4 mg experienced a mean body weight reduction of 9.6%, compared to a 3.4% reduction in the placebo group. Additionally, 68.8% of participants on semaglutide 2.4 mg achieved at least a 5% weight reduction, compared to 28.5% in the placebo group.

3. Effect of subcutaneous semaglutide vs placebo as an adjunct to intensive behavioral therapy on body weight in adults with overweight or obesity (STEP 3), published in JAMA Network (2021)

In the STEP 3 trial, the semaglutide group experienced a mean body weight decrease of 16.0% from baseline compared to a 5.7% reduction in the placebo group. Additionally, 86.6% of the semaglutide group achieved at least 5% weight loss, compared to 47.6% in the placebo group. More participants in the semaglutide group also achieved weight losses of at least 10% (75.3% vs. 27.0%) and 15% (55.8% vs. 13.2%) compared to the placebo group.

4. Effect of continued weekly subcutaneous semaglutide vs placebo on weight loss maintenance in adults with overweight or obesity (STEP 4), published in JAMA Network (2021)

In this 68-week study, participants first underwent a 20-week run-in period with once-weekly semaglutide (2.4 mg), losing an average of 10.6% body weight. Those who reached the maintenance dose were then randomized in a 2:1 ratio to either continue semaglutide or switch to placebo, with both groups receiving lifestyle interventions.

Participants who continued semaglutide treatment had a mean additional body weight reduction of 7.9% from week 20 to week 68, compared to a weight gain of 6.9% in the placebo group. In addition, continued semaglutide use led to greater improvements in waist circumference, systolic blood pressure, and physical functioning scores compared to placebo.

5. Two-year effects of semaglutide in adults with overweight or obesity (STEP 5), published in Nature Medicine (2022)

The STEP 5 trial evaluated the long-term efficacy and safety of Wegovy. Results showed that the semaglutide group experienced a significant average weight loss of 15.2% from baseline to week 104, compared to a 2.6% weight loss in the placebo group. This resulted in an estimated treatment difference of 12.6 percentage points. Additionally, 77.1% of participants in the semaglutide group achieved at least 5% weight loss, compared to 34.4% in the placebo group.

Possible Side Effects and Safety Considerations

In terms of contraindications, Wegovy should not be used by patients with a personal or family history of medullary thyroid carcinoma (MTC) or those with Multiple Endocrine Neoplasia syndrome type 2 (MEN 2). It is also contraindicated for individuals who have experienced a serious hypersensitivity reaction to semaglutide or any of the excipients in Wegovy.

Dosage and Administration

Wegovy is the first GLP-1 receptor agonist indicated for chronic weight management that offers the convenience of once-weekly administration. Each Wegovy pen comes pre-set with the appropriate dosage. The available strengths for Wegovy are:

• 0.25 mg/0.5 mL
• 0.5 mg/0.5 mL
• 1.0 mg/0.5 mL
• 1.7 mg/0.75 mL
• 2.4 mg/0.75 mL

The dosing schedule for Wegovy typically involves the following:

• Month 1: 0.25 mg once weekly
• Month 2: 0.5 mg once weekly
• Month 3: 1 mg once weekly
• Month 4: 1.7 mg once weekly
• Month 5 and beyond: 2.4 mg once weekly

After the titration phase, the maintenance dose is set at 2.4 mg once weekly. It’s important to note that the 0.25 mg, 0.5 mg, and 1 mg once-weekly doses are strictly for initiation and dose escalation purposes. For pediatric patients, if the 2.4 mg once-weekly dosage is not well-tolerated, it can be reduced to 1.7 mg once weekly. If the reduced dosage still proves intolerable, discontinuation of the treatment is required.

If a dose of Wegovy is missed and the next dose is more than 48 hours away, administer the missed dose as soon as possible. However, if the next dose is less than 48 hours away, skip the missed dose and resume the regular schedule on the next planned dosing day.

For instances where two or more consecutive doses are missed, either resume the regular dosing schedule or reinitiate Wegovy using the dose escalation schedule to minimize side effects.

Price and Availability

The list price of Wegovy is $1,349.02 per package (4 pens). However, the retail price for Wegovy in the US typically ranges between $1,500 and $1,700. This price variation can depend on factors such as the pharmacy, location, and insurance coverage.

Clinical Studies

Five large phase III trials evaluated liraglutide for weight management. Four were part of the SCALE program, examining both diabetic and non-diabetic populations.

Weight maintenance and additional weight loss with liraglutide after low-calorie-diet-induced weight loss (SCALE Maintenance), published in the International Journal of Obesity (2013)

This 56-week study evaluated the ability of 3.0 mg liraglutide to sustain weight loss following a low-calorie diet (LCD). This trial included obese or overweight participants who had successfully lost at least 5% of their initial weight during the LCD phase. The results demonstrated that participants treated with liraglutide experienced an average weight loss of 6.2% from their baseline, compared to just 0.2% in the placebo group. Additionally, 50.5% of those receiving liraglutide achieved a weight loss of 5% or more, while only 21.8% of participants in the placebo group reached this threshold.

A Randomized, controlled trial of 3.0 mg of liraglutide in weight management (SCALE Obesity and Prediabetes), published in The New England Journal of Medicine (2015)

The SCALE Obesity and Prediabetes trial found that participants treated with liraglutide lost an average of 8.0% of their baseline weight, compared to 2.6% in the placebo group. Moreover, 63.2% of the liraglutide group achieved a weight loss of 5% or more, significantly higher than the 27.1% in the placebo group.

Efficacy of liraglutide for weight loss among patients with type 2 diabetes (SCALE Diabetes), published in JAMA Network (2015)

This trial evaluated the efficacy and safety of liraglutide for weight management in adults with overweight or obesity and type 2 diabetes. The results indicated that participants treated with liraglutide experienced an average weight loss of 6.0% from their baseline, compared to 2.0% in the placebo group. Additionally, 54.3% of those receiving liraglutide achieved a weight loss of 5% or more, while only 21.4% of participants in the placebo group reached this threshold.

Effect of liraglutide 3.0?mg in individuals with obesity and moderate or severe obstructive sleep apnea (SCALE Sleep Apnea), published in the International Journal of Obesity (2016)

Over a 32-week period, participants were randomly assigned to receive either liraglutide 3.0 mg or a placebo, with weight loss as a secondary endpoint. The study found that participants treated with liraglutide lost an average of 5.7% of their baseline weight, compared to 1.6% in the placebo group. Moreover, 46.3% of the liraglutide group achieved a weight loss of 5% or more, significantly higher than the 18.5% in the placebo group.

Possible Side Effects and Safety Considerations

Serious side effects of Saxenda include:

• Risk of thyroid C-tell tumors
• Acute pancreatitis
• Acute gallbladder disease
• Risk for hypoglycemia with concomitant use of anti-diabetic therapy
• Increased heart rate
• Renal Impairment
• Hypersensitivity Reactions
• Suicidal Behavior and Ideation

Saxenda is contraindicated for individuals with a personal or family history of medullary thyroid carcinoma or those diagnosed with Multiple Endocrine Neoplasia syndrome type 2 (MEN 2). This restriction is due to the potential risk of thyroid tumors associated with the medication.

Additionally, Saxenda should not be used by individuals who have exhibited hypersensitivity to liraglutide or any of the excipients in the formulation. Hypersensitivity reactions can range from mild to severe and necessitate discontinuation of the drug.

Lastly, Saxenda is contraindicated during pregnancy as it can potentially harm the fetus. Pregnant women should avoid using this medication to ensure the safety and health of their unborn child. These contraindications are crucial to consider to prevent serious adverse effects and ensure patient safety.

Dosage and Administration

Saxenda is packaged in a box containing five prefilled pens, each holding 18 mg of liraglutide. The pens are designed for adjustable dosing in increments of 0.6 mg, 1.2 mg, 1.8 mg, 2.4 mg, and 3 mg per injection. The initial dose starts at 0.6 mg once daily for the first week, gradually increasing each week:

• Week 1: 0.6 mg once daily
• Week 2: 1.2 mg once daily
• Week 3: 1.8 mg once daily
• Week 4: 2.4 mg once daily
• Week 5 and onwards: 3 mg once daily

The maintenance dose is typically 3 mg daily, but pediatric patients may use 2.4 mg. If patients struggle with dosage increases, adjustments can be postponed. At the 3 mg daily dose, each pen provides six doses, lasting nearly a week, making a box of five pens sufficient for one month at the maintenance dose.

If a dose of Saxenda is missed, the patient should continue with their regular once-daily regimen as prescribed at the next scheduled dose, without taking an extra dose or increasing the dose to make up for the missed one. However, if more than three days have passed since the last dose, the patient should restart Saxenda at 0.6 mg daily and follow the dose escalation schedule.

Price and Availability

Saxenda is available at a list price of $1,349.02 for a package containing five pens. However, the retail price in the US can vary, typically ranging from $1,300 to $1,600.
