- DRUGS IN CLASS
- GLP-1 analogs
- Semaglutide (Wegovy®) is a GLP-1 analog, a drug class originally developed to treat type 2 diabetes. Patients receiving GLP-1 analogs sometimes saw significant weight loss, creating interest in using them as an obesity treatment. Another GLP-1 analog, liraglutide (Saxenda®), was FDA-approved for weight loss in 2014.
- Semaglutide is available in three medications: Wegovy®, Ozempic®, and Rybelsus®. Ozempic® (injection) and Rybelsus® (tablet) are FDA-approved to treat type 2 diabetes, and Wegovy® is approved for weight loss.
- MECHANISM OF ACTION
- GLP-1 analogs
- Glucagon-like peptide-1 (GLP-1) is a hormone secreted into the bloodstream by special cells in the intestine in response to food consumption. GLP-1 has the following actions: (1) slows gastric emptying; (2) stimulates insulin release and suppresses glucagon secretion in the pancreas; (3) suppresses appetite in the brain. An enzyme called dipeptidyl peptidase-4 (DPP-4) rapidly metabolizes GLP-1, rendering it inactive.
- GLP-1 analogs have a similar structure to endogenous GLP-1, mimicking its actions in the pancreas, stomach, and brain. They have also been modified so that DPP-4 cannot metabolize them.
- FDA-APPROVED INDICATIONS
- Weight loss (adults)
- As an adjunct to a reduced-calorie diet and increased physical activity for chronic weight management in adults with either of the following:
- BMI ≥ 30 (obesity)
- BMI ≥ 27 (overweight) in the presence of at least one weight-related comorbid condition (e.g. hypertension, type 2 diabetes mellitus, or dyslipidemia)
- See BMI calculator for adults
- Weight loss (children ≥ 12 years old)
- As an adjunct to a reduced-calorie diet and increased physical activity in pediatric patients aged 12 years and older with an initial BMI at the 95th percentile or greater for age and sex. See BMI calculator for children.
- WEIGHT LOSS
- Overview
- The effects of Wegovy on weight loss were studied in the five trials detailed below. In the first two trials, Wegovy was compared to placebo in adults without diabetes. In the third trial, all patients were given Wegovy for 20 weeks and then randomized to continue it or switch to placebo for 48 additional weeks. In the fourth trial, it was compared to Ozempic and placebo in adults with diabetes, and in the fifth trial, it went head-to-head with Saxenda, another GLP-1 agonist approved for weight loss.

Findings: Among adults with overweight or obesity without diabetes, once-weekly subcutaneous semaglutide compared with once-daily subcutaneous liraglutide, added to counseling for diet and physical activity, resulted in significantly greater weight loss at 68 weeks.
- Summary
- Wegovy achieved impressive weight loss in the trials detailed above, and it was decisively better than Saxenda in the STEP 8 trial.
- In the STEP 2 trial that only enrolled overweight diabetics, Wegovy caused more weight loss than Ozempic 1 mg, but the difference was not overwhelming (9.6% vs 7%). A1C reductions were also similar between the groups (1.6% vs 1.5%).
- In the STEP 4 trial, patients lost 10.6% of their body weight after 20 weeks of Wegovy, and those who continued it lost an additional 7.9% over 48 weeks. Patients who were switched to placebo gained back 6.9%.
- Gastrointestinal side effects were common in all the trials but did not lead to a large number of discontinuations

Findings: Among adolescents with obesity, once-weekly treatment with a 2.4-mg dose of semaglutide plus lifestyle intervention resulted in a greater reduction in BMI than lifestyle intervention alone
- Summary
- Wegovy caused impressive weight loss in the STEP TEENS study, and its effects were greater than other drugs approved for adolescent obesity (see Qsymia and Saxenda). As expected, gastrointestinal side effects were common, and 4% of Wegovy-treated patients experienced cholelithiasis, a known adverse effect of rapid weight loss. In 2022, Wegovy received FDA approval to treat adolescent obesity based on the STEP TEENS study.
- SIDE EFFECTS
- Gastrointestinal (GI) side effects
- Gastrointestinal complaints are the most common side effects of Wegovy. To help prevent these issues, Wegovy is started at a low dose and titrated gradually. Incidences of GI complaints from Wegovy trials are presented in the table below.
| Side effect | Wegovy (N=1261) |
Placebo (N=2116) |
|---|---|---|
| Nausea | 44% | 16% |
| Diarrhea | 30% | 16% |
| Vomiting | 24% | 6% |
| Constipation | 24% | 11% |
| Abdominal pain | 20% | 10% |
| Dyspepsia | 9% | 3% |
| Abdominal distension | 7% | 5% |
| Belching | 7% | < 1% |
| Flatulence | 6% | 4% |
- Hypoglycemia
- Wegovy by itself does not pose a significant risk of hypoglycemia. When it is taken with diabetes medications, particularly insulin and insulin secretagogues, the risk of hypoglycemia is increased. In the STEP 1 Study that only enrolled nondiabetics, Wegovy did not increase the risk of hypoglycemia. In trials involving diabetics, the incidence of hypoglycemia was 6.2% in Wegovy-treated patients and 2.5% in placebo-treated patients.
- Patients who are taking concomitant diabetes medications should monitor their blood sugars closely and be prepared to treat hypoglycemia (see hypoglycemia for more)
- Injection site reactions
- Injection site reactions, including pruritus, erythema, inflammation, induration, and irritation, may occur. In studies, reactions were reported in 1.4% of Wegovy-treated patients and 1.0% of placebo-treated patients.
- Hypersensitivity reactions
- Serious hypersensitivity reactions, including anaphylaxis and angioedema, have been reported with semaglutide
- Avoid use in patients with known hypersensitivity to semaglutide and use caution in patients with a history of reactions to other GLP-1 analogs
- Semaglutide antibodies
- Semaglutide can induce an immune response that leads to the production of anti-semaglutide antibodies, and in some cases, these antibodies cross-react with endogenous GLP-1
- In trials, 2.9% of Wegovy-treated patients developed anti-semaglutide antibodies, and of these patients, 56% had antibodies that cross-reacted with endogenous GLP-1. The effects of these antibodies on efficacy and hypersensitivity reactions are unknown.
- Pancreatitis
- Acute pancreatitis has been reported in patients receiving GLP-1 analogs, including semaglutide. In trials, acute pancreatitis occurred in 4 Wegovy-treated patients (0.2 cases per 100 patient-years) and 1 placebo-treated patient (< 0.1 cases per 100 patient-years). Wegovy has not been studied in patients with a history of pancreatitis. If symptoms of pancreatitis occur (e.g. abdominal pain, nausea, vomiting), discontinue Wegovy and initiate appropriate care.
- Decreased kidney function
- There have been case reports of decreased kidney function in patients receiving semaglutide. In most cases, patients were experiencing GI side effects of semaglutide (e.g. nausea, vomiting, and/or diarrhea) that can lead to dehydration and worsening kidney function.
- Use caution in patients with renal impairment, and monitor renal function in patients experiencing significant GI reactions
- Hypotension and syncope
- GI side effects from Wegovy can lead to dehydration and low blood pressure. In trials, hypotensive events were reported in 1.3% of Wegovy-treated patients and 0.4% of placebo-treated patients, and syncope occurred in 0.8% and 0.2%, respectively. Patients taking antihypertensives are at greater risk. Monitor blood pressure closely in susceptible patients.
- Gallbladder disease
- In adult trials, cholelithiasis was more common in Wegovy-treated patients than placebo-treated patients (1.6% vs 0.7%), as was cholecystitis (0.6% vs 0.2%). In adolescent trials, Wegovy-treated patients were also more likely to experience cholelithiasis (3.8% vs 0%) and cholecystitis (0.8% vs 0%). Substantial or rapid weight loss can increase the risk of cholelithiasis; however, even after accounting for the degree of weight loss, Wegovy-treated patients still had a higher incidence of acute gallbladder disease.
- Patients who report symptoms of gallbladder disease (e.g. abdominal pain, nausea, vomiting) should have a prompt workup
- Thyroid cancer
- In toxicology studies, a dose-dependent and treatment-duration-dependent increase in the incidence of malignant and benign thyroid medullary tumors (C-cell tumors) was observed in rats and mice receiving clinically relevant doses of GLP-1 analogs. This prompted the FDA to place a boxed warning about medullary thyroid cancer on some GLP-1 analogs, including semaglutide. It is unknown if GLP-1 analogs increase the risk of tumors in humans as the incidence of these events is too low to establish causality.
- Semaglutide is contraindicated in patients with a personal or family history of medullary thyroid cancer or multiple endocrine neoplasia 2, a condition that increases the risk for medullary thyroid cancer. Patients should be aware of the potential risk and report any thyroid symptoms if they occur. Medullary thyroid cancer usually causes elevations in calcitonin levels above 50 ng/L.
- Diabetic retinopathy
- In adult type 2 diabetic trials, diabetic retinopathy was reported in 4% of Wegovy-treated patients and 2.7% of placebo-treated patients. Rapid improvement in glucose control has been associated with a temporary worsening of diabetic retinopathy. Patients with baseline diabetic retinopathy may be at greater risk for worsening and should be monitored appropriately. The long-term effects of semaglutide on diabetic retinopathy have not been studied.
- Pancreatic enzyme elevations
- In trials, patients treated with Wegovy had an average increase from baseline in amylase of 16% and lipase of 39%. No increase was observed in placebo-treated patients. The significance of these effects is unknown.
- Heart rate increase
- In adult trials, Wegovy-treated patients had an average increase in heart rate of 1 - 4 bpm compared to placebo. Maximum increases of 10 - 19 bpm from baseline at any visit were observed in more Wegovy-treated patients than placebo-treated patients (41% vs 34%), as were increases of ≥ 20 bpm (26% vs 16%). In adolescent trials, changes in heart rate of 20 bpm or more were more common in Wegovy-treated patients than placebo-treated patients (54% vs 39%).
- Monitor heart rates in Wegovy-treated patients and discontinue therapy if sustained increases occur
- Suicide behavior and ideation
- Suicidal behavior and ideation have been reported in clinical trials with other weight management products. Monitor patients for depression, suicidal thoughts, or other unusual changes in mood. Avoid use in patients with a history of suicidal behavior, and discontinue therapy in patients who develop suicidal ideation.
- CONTRAINDICATIONS
- A personal or family history of medullary thyroid carcinoma (MTC) or in patients with Multiple Endocrine Neoplasia syndrome type 2 (MEN 2)
- A prior serious hypersensitivity reaction to semaglutide or to any of the excipients in Wegovy
- PRECAUTIONS
- Kidney disease
- No dose adjustment is necessary for any degree of renal impairment
- Liver disease
- No dose adjustment is necessary for any degree of hepatic impairment
- DRUG INTERACTIONS
- NOTE: The drug interactions presented here are NOT all-inclusive. Other interactions may exist. Drug interaction checkers provide the most efficient and practical way to check for interactions among multiple medications. A free interaction checker is available from Drugs.com (see Drugs.com interactions checker).
- Semaglutide (Wegovy®)
- Insulin and insulin secretagogues - when combined with insulin or insulin secretagogues (e.g. sulfonylureas, meglitinides), semaglutide increases the risk of hypoglycemia. Monitor blood sugars closely and adjust medications as needed.
- Drugs affected by decreased gastric emptying - see gastric emptying below
- Drugs that alter gastrointestinal motility - drugs that slow gastrointestinal motility may potentiate the gastric-slowing effects of GLP-1 analogs
- Drugs affected by gastric emptying
- Medications are partially digested in the stomach before being emptied into the small intestine, where most drug absorption occurs. GLP-1 analogs slow the process of gastric emptying, potentially altering the absorption of some drugs. In many cases, the overall effect on the medication's therapeutic action is not significant, but the efficacy of some drugs (see below) may be altered.
- Antibiotics
- Antibiotics require rapid absorption to achieve their desired therapeutic effect
- Drugs with a narrow therapeutic index
- Drugs with narrow therapeutic index may have their steady-state altered by delayed gastric emptying
- Examples of drugs with a narrow therapeutic index:
- Carbamazepine (Tegretol®)
- Cyclosporine (Neoral®)
- Digoxin
- Levothyroxine (Synthroid®)
- Lithium
- Phenytoin (Dilantin®)
- Tacrolimus (Prograf®)
- Theophylline (Theo-24®)
- Warfarin (Coumadin®) [2]
- Metabolism and clearance
- Semaglutide is metabolized by proteolytic cleavage and beta-oxidation. The remnants of these processes are eliminated via the urine and feces.
