What is semaglutide?
Semaglutide is a glucagon-like peptide-1 (GLP-1) receptor agonist, originally developed to treat type 2 diabetes mellitus by mimicking the action of endogenous GLP-1. It has since been licensed for weight management in higher doses under brand names such as Saxenda and Wegovy. Semaglutide is administered by subcutaneous injection in a prefilled pen device, usually once weekly for diabetes and once daily for weight loss formulations. The medicine helps lower blood glucose levels by enhancing insulin secretion, suppressing glucagon release, slowing gastric emptying, and reducing appetite. Recent clinical trials have demonstrated not only significant improvements in glycaemic control but also sustained weight loss in overweight and obese individuals.
How does semaglutide work?
GLP-1 receptor activation
Semaglutide binds to the GLP-1 receptor on pancreatic β-cells, increasing cyclic AMP levels and enhancing glucose-dependent insulin secretion. This mechanism reduces postprandial and fasting plasma glucose without causing hypoglycaemia when used alone.
Inhibition of glucagon release
By decreasing glucagon secretion from α-cells in the pancreas, semaglutide further contributes to lower hepatic glucose production, improving overall glycaemic control.
Delay in gastric emptying
Semaglutide slows the rate at which the stomach empties its contents into the small intestine, leading to a reduction in post-meal blood sugar spikes and promoting satiety.
Appetite suppression and central effects
GLP-1 receptors are also present in the hypothalamus, where semaglutide influences hunger signals. This central effect contributes to reduced calorie intake and supports weight loss in patients with obesity.
Uses and benefits
Semaglutide carries dual indications in most markets: as a glucose-lowering agent for type 2 diabetes (marketed under names such as Ozempic) and as a weight management solution (brand names include Wegovy and generic equivalents) in adults with a body mass index (BMI) ≥30 kg/m² or ≥27 kg/m² with at least one weight-related comorbidity. Key benefits include:
- Reduction in HbA1c by up to 1.5–2.0% at optimal doses compared with baseline in diabetes trials;
- Average weight loss of 10–15% at 68 weeks in obesity studies;
- Improved cardiovascular outcomes with a reduction in major adverse cardiovascular events (MACE) in high-risk diabetic populations;
- Lower risk of hypoglycaemia when used as monotherapy or in combination with metformin.
Additional off-label research areas include non-alcoholic fatty liver disease, polycystic ovary syndrome, and post-bariatric surgery maintenance. While many of these studies show promise, they remain investigational and require further validation.
Dosage and administration
Standard dosing for type 2 diabetes
The usual starting dose of semaglutide (Ozempic® pen) for glycaemic control is 0.25 mg once weekly for 4 weeks, which is intended to mitigate gastrointestinal side effects. After the initial period, the dose is typically increased to 0.5 mg once weekly. If further reduction in HbA1c is needed and the medicine is well tolerated, some patients may be escalated to 1 mg once weekly. Maximum doses of 2 mg once weekly are approved in certain regions.
Weight management dosing
The weight loss protocol (Wegovy® pen or generic equivalent) begins at 0.25 mg once weekly, increasing by 0.25 mg increments each month up to 2.4 mg once weekly, subject to patient tolerability and clinical response. Dose escalation spans a minimum of 16–20 weeks before reaching the maintenance dose.
Injection technique
Semaglutide is supplied in a disposable pen. Patients should rotate injection sites (abdomen, thigh, upper arm), clean the skin with an alcohol swab, pinch a small skin fold, insert the needle at 90°, press the dose button until the dose counter shows zero, and hold for 5–10 seconds before withdrawal. Proper sharps disposal in a puncture-resistant container is essential.
Missed dose instructions
If a weekly dose is missed, administer as soon as possible within 5 days of the scheduled day. If more than 5 days have passed, skip the missed dose and resume the regular weekly schedule. Do not take two doses to make up for a missed dose.
Side effects and safety
Common adverse reactions in clinical trials included nausea (20–40%), diarrhoea (10–25%), vomiting (10–20%), constipation (5–15%), and abdominal pain (5–10%). Most gastrointestinal symptoms occur during dose escalation and diminish over time. Other side effects include:
- Headache (5–15%);
- Dyspepsia (5–10%);
- Fatigue (2–5%).
Serious safety considerations:
- Pancreatitis: Cases have been reported; discontinue if suspected.
- Thyroid C-cell tumours: Observed in rodent studies; relevance to humans is uncertain. Contraindicated in patients with a personal or family history of medullary thyroid carcinoma or MEN 2.
- Acute gallbladder disease: Reports of cholelithiasis and cholecystitis.
- Hypoglycaemia: Risk increases when combined with insulin or sulfonylureas; dose adjustments may be needed.
Regular monitoring of renal function, liver enzymes, and pancreatic markers may be advised, especially in high-risk groups. Report any severe abdominal pain or persistent gastrointestinal upset to a healthcare professional immediately.
Who can use semaglutide?
Semaglutide is indicated for adults with type 2 diabetes inadequately controlled on diet and exercise alone or as an adjunct to other glucose-lowering therapies. For weight management, adults with BMI ≥30 kg/m² or ≥27 kg/m² with one comorbidity (e.g., hypertension, dyslipidaemia) may be eligible. It is not approved for type 1 diabetes or diabetic ketoacidosis. Caution is required in:
- Patients with severe gastrointestinal disease;
- Those with a history of pancreatitis;
- Individuals with gastroparesis;
- People with significant renal or hepatic impairment.
Generic vs branded semaglutide
Branded semaglutide products such as Ozempic® and Wegovy® are produced by Novo Nordisk under patent protection in most markets. Generic manufacturing of semaglutide has begun in jurisdictions where patent exclusivity has expired or is circumvented by regulatory pathways. Generic semaglutide must demonstrate bioequivalence to the reference product in terms of pharmacokinetics, efficacy, and safety. While the active peptide sequence remains identical, differences may exist in excipients, device design, and pen mechanism. Customers seeking a cheaper alternative often choose generic semaglutide pens, which can reduce the treatment cost by 30–50%, depending on the supplier and pack size.
UK legal status and prescription requirements
