What Wegovy® Is and How It Works

Wegovy® contains semaglutide, a GLP-1 receptor agonist. It helps regulate appetite, reduces hunger, and supports lower calorie intake. It also delays gastric emptying, which can help you feel full longer. The result is a clinically supported tool for chronic weight management when paired with a reduced-calorie diet and increased physical activity. You can explore related options in our Weight Loss Medication Products category.

At the cellular level, GLP-1 receptor activation influences satiety centers in the brain. It also affects post-meal insulin and glucagon responses. Wegovy is not a stimulant and does not contain hormones like thyroid hormone. It is a prescription therapy that follows a gradual dose schedule to improve tolerability.

Who Wegovy® Is For

Wegovy is indicated for adults with obesity, or overweight with at least one weight-related condition such as hypertension, dyslipidemia, or type 2 diabetes. It is also indicated for adolescents aged 12 years and older with obesity, based on age- and sex-adjusted BMI cutoffs. People with a personal or family history of medullary thyroid carcinoma or MEN2 should not use semaglutide. Those with a history of pancreatitis should discuss risks carefully with their clinician. For broader background on the condition, see our Obesity page.

Dosage and Usage

Wegovy is injected subcutaneously once weekly on the same day each week. The standard dose schedule starts low and steps up. A typical sequence is:

• 0.25 mg once weekly for 4 weeks
• 0.5 mg once weekly for 4 weeks
• 1 mg once weekly for 4 weeks
• 1.7 mg once weekly for 4 weeks
• Maintenance: 1.7 mg or 2.4 mg once weekly

The maximum recommended dose is 2.4 mg once weekly. If tolerability issues occur during escalation, clinicians may extend a step before progressing. Do not change your schedule without medical guidance. For a practical overview of the weekly plan, you can read Wegovy® Doses.

Strengths and Forms

Wegovy is supplied as single-use, prefilled pens intended for subcutaneous injection. Common strengths include 0.25 mg, 0.5 mg, 1 mg, 1.7 mg, and 2.4 mg pens. Each pen delivers one full dose. Packaging and availability can vary by strength and over time.

Missed Dose and Timing

If a dose is missed and the next scheduled dose is more than several days away, the label allows taking the missed dose when remembered. If the next dose is too close, skip the missed dose and return to the regular weekly schedule. If multiple doses are missed, clinicians may consider re-titration to improve tolerability. When in doubt, follow the official label and consult your prescriber.

Storage and Travel Basics

Store Wegovy pens in the refrigerator before use. Keep them in the original carton to protect from light. Do not freeze and do not use if the pen has been frozen. Unopened pens may be kept at room temperature for a limited period as specified on the official label. For travel, use an insulated bag or cold pack to keep within labeled temperature guidance, and avoid direct heat or sunlight. Do not use pens past their labeled time out of refrigeration.

Pen Handling and Sharps Disposal

Each Wegovy pen is single-use. Review the Instructions for Use that come with your pen before your first injection. A general sequence is:

• Choose an injection site on the abdomen, thigh, or upper arm.
• Remove the cap as directed and place the pen flat against the skin.
• Press and hold the button until the dose is delivered. Keep it pressed for the labeled hold time.
• Confirm completion per the window or indicator, then remove the pen from the skin.

Place used pens in a sharps container. Follow local or state rules for sharps disposal. Many GLP-1 pens follow similar handling steps. For another pen device example, see Mounjaro® Kwikpen.

Benefits

Label-supported benefits include clinically meaningful weight loss when used with diet and activity. The once-weekly schedule improves convenience and may help adherence. Single-use pens remove the need to measure doses. Many patients also appreciate that Wegovy acts on appetite pathways rather than acting as a stimulant.

Side Effects and Safety

• Nausea
• Vomiting
• Diarrhea
• Constipation
• Abdominal pain
• Indigestion or burping
• Dizziness or headache
• Fatigue
• Injection site reactions

Serious risks can include pancreatitis, gallbladder disease, acute kidney injury from dehydration, hypersensitivity reactions, and a possible risk of thyroid C-cell tumors. Wegovy carries a boxed warning about thyroid C-cell tumors and is contraindicated in patients with a personal or family history of medullary thyroid carcinoma or MEN2. In people with type 2 diabetes, GLP-1 therapy can be associated with diabetic retinopathy complications when glycemic control changes quickly. Hypoglycemia can occur when used with insulin or sulfonylureas. Seek urgent care for symptoms of severe allergic reactions, severe abdominal pain, or signs of dehydration.

Drug Interactions and Cautions

Using Wegovy with insulin or sulfonylureas raises hypoglycemia risk. Delayed gastric emptying may affect how fast some oral medicines are absorbed. Clinicians often monitor therapies with a narrow therapeutic index. Caution is advised with other weight loss medications until a prescriber reviews your regimen. Wegovy is not recommended in pregnancy. Breastfeeding considerations should be discussed with a clinician. Do not use Wegovy alongside other semaglutide-containing products.

What to Expect Over Time

Appetite usually declines during dose escalation. Gastrointestinal effects are most common in the early weeks and often lessen as the body adjusts. Weight loss tends to build gradually over several months when paired with diet and activity. Some people reach a plateau and need lifestyle adjustments or dose stabilization. For broader context, see Wegovy® Weight Loss.

Compare With Alternatives

Several FDA-approved weight management medicines are available. Liraglutide is a daily GLP-1 option sold as Saxenda®. Tirzepatide is a weekly GIP/GLP-1 agent approved for weight loss as Zepbound®. Both have label-supported dosing schedules and lifestyle requirements. Mechanisms, dosing frequency, and tolerability profiles differ across agents.

Availability and Substitutions

Supply can vary by strength. If a specific pen is unavailable, a prescriber may recommend an alternative option or a different strength with a revised plan. We cannot guarantee restock timings. Your clinician determines the best substitute when needed.

Patient Suitability and Cost Saving Tips

Wegovy may suit adults with obesity or overweight with related conditions who can follow a weekly injection plan. It may not be appropriate for those with a history of medullary thyroid carcinoma, MEN2, pancreatitis, or pregnancy. Discuss kidney, gallbladder, and retinal health histories before starting. Consider multi-month quantities when appropriate to reduce per-shipment costs. Set calendar reminders for weekly injections and use refill reminders to avoid gaps in therapy.
