Ozempic Vs. Wegovy: Drug Comparison

Ozempic^® (semaglutide) is an injectable medication used to improve blood sugar control in adults with type 2 diabetes and to reduce the risk of major cardiovascular events in individuals with established heart disease. It works by mimicking the hormone glucagon-like peptide-1 (GLP-1), which increases insulin secretion, decreases glucagon release, and slows gastric emptying. Administered once weekly, Ozempic is often part of a comprehensive treatment plan that includes diet and exercise. Common side effects include nausea, vomiting, diarrhea, and abdominal pain, and it should be used with caution in patients with a history of pancreatitis​.

Wegovy^® (semaglutide) is an injectable medication approved for chronic weight management in adults with obesity or overweight with at least one weight-related condition, such as hypertension, type 2 diabetes, or high cholesterol. It works by mimicking the hormone glucagon-like peptide-1 (GLP-1), which regulates appetite and food intake, leading to reduced calorie consumption and significant weight loss. Wegovy is administered once weekly and is intended to be used in conjunction with a reduced-calorie diet and increased physical activity. Common side effects include nausea, diarrhea, vomiting, and constipation. It should be used with caution in patients with a history of pancreatitis and is not recommended for use in pregnant or breastfeeding individuals​.

Glucagon-like peptide-1 (GLP-1) receptor agonist

Glucagon-like peptide-1 (GLP-1) receptor agonist

Ozempic (semaglutide) is indicated:

• As an adjunct to diet and exercise to improve glycemic control in adults with type 2 diabetes mellitus

• To reduce the risk of major adverse cardiovascular events in adults with type 2 diabetes mellitus and established cardiovascular disease

Wegovy (semaglutide) is indicated in combination with a reduced calorie diet and increased physical activity:

• To reduce the risk of major adverse cardiovascular events (cardiovascular death, non-fatal myocardial infarction, or non-fatal stroke) in adults with established cardiovascular disease and either obesity or overweight

• To reduce excess body weight and maintain weight reduction long term in:

  • Adults and pediatric patients aged 12 years and older with obesity

  • Adults with overweight in the presence of at least one weight-related comorbid condition

• Typically taken as an injection once weekly

• Comes in single-patient-use pens that deliver 0.25 mg, 0.5 mg, 1 mg, or 2 mg per injection

• Typically taken as an injection once weekly

• Comes in single-dose pens that deliver 0.25 mg, 0.5 mg, 1 mg, 1.7 mg, or 2.4 mg per injection

The most common adverse reactions, reported in ≥5% of patients are:

• Nausea

• Vomiting

• Diarrhea

• Abdominal pain

• Constipation

Most common adverse reactions (incidence ≥5%) in adults or pediatric patients aged 12 years and older are:

• Nausea

• Diarrhea

• Vomiting

• Constipation

• Abdominal pain

• Headache

• Fatigue

• Indigestion

• Dizziness

• Abdominal distension

• Belching

• Low blood sugar in patients with type 2 diabetes

• Flatulence

• Inflammation of the digestive system

• Gastroesophageal reflux disease (heartburn)

• Inflammation of the nasal cavities and back of the throat

• Personal or family history of medullary thyroid carcinoma or in patients with multiple endocrine neoplasia syndrome type 2

• Serious hypersensitivity reaction to semaglutide or any of the excipients in Ozempic

• Drug interactions: Ozempic delays gastric emptying and may impact the absorption of concomitantly administered oral medications

• Personal or family history of medullary thyroid carcinoma or in patients with multiple endocrine neoplasia syndrome type 2

• Known hypersensitivity to semaglutide or any of the excipients in Wegovy

• Drug interactions: Wegovy delays gastric emptying. May impact absorption of concomitantly administered oral medications

• Pancreatitis

• Diabetic retinopathy complications

• Never share an Ozempic pen between patients, even if the needle is changed

• Low blood sugar: Concomitant use with an insulin secretagogue or insulin may increase the risk of low blood sugar, including severe low blood sugar

• Acute kidney injury

• Hypersensitivity reactions

• Acute gallbladder disease

• Females and males of reproductive potential: Discontinue Ozempic in women at least 2 months before a planned pregnancy due to the long washout period for semaglutide

• Acute pancreatitis

• Acute gallbladder disease

• Low blood sugar: Concomitant use with insulin or an insulin secretagogue may increase the risk of low blood sugar, including severe low blood sugar

• Acute kidney injury

• Hypersensitivity reactions

• Diabetic retinopathy complications in patients with type 2 diabetes

• Heart rate increase

• Suicidal behavior and ideation

• Pregnancy: May cause fetal harm. When pregnancy is recognized, discontinue Wegovy

• Females and males of reproductive potential: Discontinue Wegovy at least 2 months before a planned pregnancy because of the long half-life of semaglutide

WARNING: RISK OF THYROID C-CELL TUMORS

In rodents, semaglutide causes thyroid C-cell tumors. It is unknown whether Ozempic causes thyroid C-cell tumors, including medullary thyroid carcinoma (MTC), in humans as the human relevance of semaglutide-induced rodent thyroid C-cell tumors has not been determined.

Ozempic is contraindicated in patients with a personal or family history of MTC or in patients with multiple endocrine neoplasia syndrome type 2 (MEN 2). Counsel patients regarding the potential risk of MTC and symptoms of thyroid tumors.

WARNING: RISK OF THYROID C-CELL TUMORS

In rodents, semaglutide causes thyroid C-cell tumors at clinically relevant exposures. It is unknown whether Wegovy causes thyroid C-cell tumors, including medullary thyroid carcinoma (MTC), in humans as the human relevance of semaglutide-induced rodent thyroid C-cell tumors has not been determined.

Wegovy is contraindicated in patients with a personal or family history of MTC or in patients with multiple endocrine neoplasia syndrome type 2 (MEN 2). Counsel patients regarding the potential risk of MTC and symptoms of thyroid tumors.
