Wegovy Pen

Wegovy Pen is a prescription medication containing semaglutide, a glucagon-like peptide-1 (GLP-1) receptor agonist, approved by the U.S. Food and Drug Administration (FDA) for chronic weight management. It is indicated for adults with a body mass index (BMI) of >30 kg/m² (obesity) or >27 kg/m² (overweight) who also have weight-related medical conditions such as hypertension, dyslipidemia, or type 2 diabetes.

Unlike other GLP-1 receptor agonists like Ozempic and Saxenda, Wegovy is specifically developed and dosed for weight loss rather than glycemic control. Its formulation and delivery system are tailored to provide sustained therapeutic effects with once-weekly injections.

Wegovy is approved in multiple regulatory jurisdictions, including the United States, European Union, Canada, and several Asia-Pacific markets. It is available in prefilled single-use pens with dose increments ranging from 0.25 mg to 2.4 mg.

The active pharmaceutical ingredient in Wegovy is semaglutide, a synthetic analog of human GLP-1 with 94% sequence homology. Semaglutide is modified to resist enzymatic degradation, allowing for extended half-life and once-weekly dosing.

• Active ingredient: Semaglutide
• Excipients: Disodium phosphate dihydrate, sodium chloride, and water for injection

Wegovy is administered as a subcutaneous injection. Its extended-release effect is achieved through molecular modifications and formulation science, ensuring stable plasma concentrations over seven days.

Wegovy and Ozempic both contain the same active ingredient, semaglutide, a GLP-1 receptor agonist. The primary difference lies in their approved uses and dosage: Ozempic is primarily for treating Type 2 diabetes and reducing cardiovascular risk in diabetic patients, while Wegovy is specifically approved for chronic weight management at a higher dosage. Both work by mimicking a natural hormone that helps regulate blood sugar, slow digestion, and reduce appetite.

Wegovy (semaglutide) is a GLP-1 receptor agonist, mimicking a single gut hormone to reduce appetite and slow gastric emptying for weight loss. Zepbound (tirzepatide) is a "dual-agonist," targeting both GLP-1 and GIP receptors, which can lead to greater weight loss in clinical trials compared to Wegovy. Both are once-weekly injectable medications approved for chronic weight management in conjunction with diet and exercise.

Saxenda (liraglutide) and Wegovy (semaglutide) are both injectable medications from the GLP-1 receptor agonist class, used for chronic weight management alongside diet and exercise. The key differences are their dosing frequency and efficacy: Saxenda is typically injected daily, while Wegovy is injected once weekly and generally leads to greater average weight loss.

Wegovy (semaglutide) and Mounjaro (tirzepatide) are both once-weekly injectable medications used for weight management, but they differ in their active ingredients and mechanisms. Wegovy is a GLP-1 receptor agonist, while Mounjaro is a dual GLP-1 and GIP receptor agonist, potentially leading to greater weight loss effects. Wegovy is FDA-approved specifically for chronic weight management, whereas Mounjaro is currently approved for Type 2 diabetes and often used off-label for weight loss.

Wegovy (semaglutide) is a GLP-1 receptor agonist, mimicking a gut hormone that helps regulate appetite and satiety. Tirzepatide (found in Mounjaro and Zepbound) is a dual agonist, activating both GLP-1 and GIP receptors, which are two different gut hormones involved in blood sugar control and appetite regulation. This dual action is thought to contribute to tirzepatide generally showing greater weight loss in clinical trials compared to semaglutide.

Wegovy is indicated for long-term weight management in adults with obesity or overweight with at least one weight-related condition. It is prescribed in conjunction with lifestyle interventions including a reduced-calorie diet and increased physical activity.

The duration of therapy depends on individual response and tolerance. Clinical trials have demonstrated sustained weight loss over 68 weeks, with many patients achieving 10-15% body weight reduction.

In clinical practice and research, Wegovy is being explored for several off-label applications:

• Polycystic Ovary Syndrome (PCOS): Semaglutide shows promise in improving weight, insulin sensitivity, and hormonal balance.
• Appetite suppression in non-diabetics: Used off-label for patients with severe obesity resistant to conventional therapies.
• Addiction and behavioral impulse control: Emerging studies are evaluating its influence on reward pathways in the brain.
• Cardiovascular risk reduction: Its weight-lowering effects may indirectly reduce major adverse cardiovascular events (MACE).

Wegovy mimics endogenous GLP-1, a hormone involved in glucose regulation and appetite control. By activating GLP-1 receptors:

• It slows gastric emptying, prolonging satiety after meals
• Reduces appetite through hypothalamic signaling
• Enhances insulin secretion in a glucose-dependent manner

This multifaceted mechanism leads to decreased caloric intake and sustained weight reduction without significant loss of lean body mass.

Wegovy (semaglutide) aids in weight reduction by imitating a hormone known as GLP 1 that controls appetite and slows the pace at which food passes from the stomach to the intestines. This results in a longer sensation of fullness, leading to decreased food consumption and, ultimately, shedding pounds.

In trials, at hospitals and healthcare facilities, the majority who used Wegovy at doses of 1.7 mg and 2.4 mg experienced weight loss ranging from 5 percent to 15 percent over a period spanning 68 weeks on average. In a study conducted in the year 2022 involving individuals grappling with weight or obesity, there was an average weight reduction of 5.9 percent, after three months following the use of semaglutide. By the end of six months post use, this figure had risen to a reduction rate reaching 10.9 percent.

Wegovy is administered via subcutaneous injection once weekly, ideally on the same day each week. Titration is essential to reduce gastrointestinal side effects:

• Week 1-4: 0.25 mg weekly
• Week 5-8: 0.5 mg weekly
• Week 9-12: 1.0 mg weekly
• Week 13-16: 1.7 mg weekly
• Maintenance dose: 2.4 mg weekly from week 17 onwards

If a dose is missed, it should be taken within 5 days. If more than 5 days have passed, the next dose should be skipped, and regular weekly administration resumed.

Instruct them to push the pen down throughout the injection and not to retract it until the yellow bar has come to a stop, moving completely and finished moving on its own. If they encounter difficulties during the injection process, suggest switching to an injection spot, like the upper leg or upper arm, or try injecting while standing up into the lower abdomen or stomach region.

• The belly area (stomach) is a chosen and usually convenient spot for injections; it's advisable to inject a minimum of 2 inches from your navel.
• When targeting the thigh for injections aim for the front of your thigh.
• Although the upper arm can serve as an injection site,  individuals might encounter challenges reaching it independently. It may require some help.

The most frequently reported side effects are gastrointestinal in nature:

• Nausea and vomiting
• Wegovy Diarrhea or constipation
• Abdominal discomfort, bloating
• Wegovy Headache and fatigue
• Injection site redness or irritation
• Wegovy hair loss

While rare, serious adverse events may occur:

• Acute pancreatitis: Abdominal pain radiating to the back, with or without vomiting
• Gallbladder disease: Including gallstones or inflammation (cholecystitis)
• Wegovy side effects cancer: Semaglutide has caused C-cell tumors in rodents; relevance in humans remains under investigation
• Kidney injury: Resulting from severe dehydration due to vomiting or diarrhea

• Wegovy may delay gastric emptying, affecting absorption of oral medications such as antibiotics and contraceptives
• Caution with insulin and sulfonylureas due to increased hypoglycemia risk
• Avoid concomitant use with other GLP-1 agonists to prevent overdose

• Personal or familial history of medullary thyroid carcinoma (MTC)
• Multiple endocrine neoplasia syndrome type 2 (MEN 2)
• Known hypersensitivity to semaglutide or any formulation component

• Thyroid tumor risk: Includes a black box warning due to rodent data suggesting increased incidence of C-cell tumors
• Gastrointestinal disorders: Use cautiously in patients with severe gastroparesis or inflammatory bowel disease
• Hypoglycemia: Especially in combination with insulin or insulin secretagogues
• Retinopathy: Rapid glucose improvement may temporarily worsen diabetic eye disease

Routine monitoring and individualized medical supervision are recommended throughout the course of treatment with Wegovy.

Using Wegovy and alcohol together is not recommended as it could amplify side effects, like nausea and dizziness associated with Wegovy treatment. Its advised to avoid alcohol while taking Wegovy to prevent any effects that can hinder your weight loss progress.

• Zepbound.
• Saxenda.
• Qsymia.
• Contrave.
• Orlistat.
• Phentermine.
• Ozempic.
• Mounjaro.

Pharmacokinetic studies indicate that semaglutide exposure in individuals aged 65 years and older is comparable to that in younger adults. Nonetheless, due to age-associated physiological changes, clinical discretion is advised.

• Renal function: Evaluate glomerular filtration rate (GFR) prior to initiation and periodically during treatment, as older patients may have diminished renal reserve.
• Hepatic function: Hepatic impairment may alter semaglutide metabolism; baseline liver function tests are advisable in this population.
• Monitoring: Although no dosage adjustments are routinely required, close observation for gastrointestinal tolerance and weight-related adverse effects is recommended.

Wegovy (semaglutide) is classified as a pregnancy category not yet assigned under the FDA's current labeling system, but animal studies have shown embryofetal toxicity at clinically relevant doses.

• Pregnancy: Discontinue Wegovy as soon as pregnancy is detected. Weight loss medications are contraindicated during pregnancy, and semaglutide's effects on fetal development remain unquantified in humans.
• Lactation: It is unknown whether semaglutide is excreted in human breast milk. Due to the potential for serious adverse reactions in nursing infants, use during breastfeeding is not recommended.

Wegovy is FDA-approved for chronic weight management in pediatric patients aged 12 to 17 years with obesity (BMI >95th percentile for age and sex). This approval follows clinical trial evidence demonstrating meaningful weight reduction and metabolic improvements in adolescents.

• Clinical data: The STEP TEENS trial indicated significant BMI reductions and improved cardiometabolic profiles in this age group.
• Children under 12: Safety and efficacy have not been established in this population. Use in pre-adolescents is not recommended pending further studies.

Wegovy therapy necessitates individualized planning and clinical vigilance. Patient tolerance, clinical response, and metabolic safety must be assessed routinely.

• Target monitoring: Regular evaluation of weight loss progression helps determine therapeutic success. A failure to lose at least 5% of baseline body weight within 16 weeks may prompt discontinuation.
• Adverse effects: Intolerable nausea, vomiting, or dehydration warrant dosage reassessment or cessation.
• Renal and electrolyte status: Monitor serum creatinine and electrolytes, particularly in patients with prior gastrointestinal loss or existing renal impairment.
• Liver enzymes: ALT, AST, and bilirubin should be assessed periodically, especially in patients with hepatic comorbidities or unexplained symptoms.

Proper storage and disposal of Wegovy pens are critical for maintaining drug efficacy and ensuring user safety.

• Refrigeration: Store pens in a refrigerator at 2°C to 8°C (36°F to 46°F) before initial use. Do not freeze. Protect from light.
• In-use storage: After first use, pens can be kept at room temperature up to 30°C (86°F) for up to 28 days.
• Disposal: Used pens should be discarded in FDA-cleared sharps containers. Never reuse or share pens to avoid cross-contamination or infection.

Although overdose with semaglutide is rare, excessive administration may provoke pronounced gastrointestinal and metabolic disturbances.

• Symptoms: Nausea, vomiting, severe abdominal pain, and potential hypoglycemia (especially when co-administered with insulin or sulfonylureas).
• Treatment: Supportive care is the cornerstone of overdose management. Ensure adequate hydration and electrolyte balance.
• Antidote: No specific antidote exists for semaglutide overdose. Hospital admission may be required in severe cases.

Proper patient education and preventive practices improve treatment outcomes and reduce risks associated with Wegovy therapy.

• Self-injection technique: Patients must be trained on subcutaneous administration in the abdomen, thigh, or upper arm. Rotation of injection sites is recommended.
• Pen hygiene: Never share pens to prevent viral or bacterial transmission. Use each pen for a single patient only.
• Lifestyle adherence: Reinforce the importance of adhering to a balanced diet and regular physical activity for maximum weight loss benefit.
• Symptom vigilance: Advise immediate medical attention if signs of pancreatitis (severe abdominal pain), allergic reactions, or dehydration occur.
