Wegovy® Injection for Chronic Weight Management

Wegovy® is a prescription semaglutide injection used with reduced-calorie diet and increased activity for chronic weight management. This page explains how it works, how to use the Wegovy pen, safety basics, and how to buy Wegovy online from Canada with US delivery from Canada at Canadian pricing, including options if paying without insurance. Wegovy ships to the US from licensed Canadian pharmacies through our referral model.

What Wegovy® Is and How It Works

At CanadianInsulin, orders are filled by licensed Canadian pharmacies after we confirm a valid prescription with your clinic. Wegovy is a GLP-1 receptor agonist. It mimics the body’s natural GLP-1 hormone, which helps control appetite and food intake. It also slows stomach emptying and supports better portion control. Together with nutrition and activity changes, it can help appropriate patients lose weight and keep it off.

Wegovy is given once weekly as a subcutaneous injection. Many people find weekly Wegovy weight loss injections easier to remember than daily dosing. The medicine works best when combined with consistent habits. Most users schedule the same day each week. If your prescriber adjusts your dose during titration, keep the same weekly schedule.

Because this is a semaglutide injection for weight loss, it may also help improve cardiometabolic markers, such as waist circumference and certain laboratory values, when used with lifestyle measures. In adults with established cardiovascular disease and obesity or overweight, Wegovy is indicated to reduce the risk of major adverse cardiovascular events, based on its FDA-approved labeling.

Who Wegovy® Is For

Wegovy is indicated for adults with a body mass index (BMI) of 30 kg/m2 or greater, or 27 kg/m2 or greater with at least one weight-related condition such as hypertension, type 2 diabetes, or dyslipidemia. It is also approved for adolescents aged 12 years and older with obesity who meet label criteria. It should be used along with a reduced-calorie diet and increased physical activity.

Do not use Wegovy if you have a personal or family history of medullary thyroid carcinoma (MTC) or if you have Multiple Endocrine Neoplasia syndrome type 2 (MEN 2). It is not recommended during pregnancy. People with a history of pancreatitis should discuss risks with their clinician. If you use insulin or a sulfonylurea, your prescriber may monitor for hypoglycemia when starting or increasing Wegovy.

Dosage and Usage

Wegovy is a once-weekly injection given under the skin of the abdomen, thigh, or upper arm. Your prescriber will start low and increase gradually to help reduce stomach-related side effects.

• Week 1 to 4: 0.25 mg once weekly
• Week 5 to 8: 0.5 mg once weekly
• Week 9 to 12: 1 mg once weekly
• Week 13 to 16: 1.7 mg once weekly
• Week 17 and ongoing: 2.4 mg once weekly (maintenance), or the highest tolerated dose on the label

Use a different injection site each week to reduce skin irritation. Do not inject into areas that are tender, bruised, or scarred. Keep the same day of the week for dosing. If you need to change the day, choose a new day at least two days after your last dose.

For a step-by-step overview of the dose schedule and tips, see the Wegovy® Doses Guide.

Strengths and Forms

Wegovy comes as single-use, prefilled pens. Each pen delivers one weekly dose. Common strengths include:

• Wegovy 0.25 mg pen
• Wegovy 0.5 mg pen
• Wegovy 1 mg pen
• Wegovy 1.7 mg pen
• Wegovy 2.4 mg pen

Availability may vary by strength. Your prescriber chooses the right starting dose and titration plan.

Missed Dose and Timing

If you miss a scheduled dose and it has been less than 5 days (120 hours), take the missed dose as soon as possible. Then resume your regular weekly schedule. If more than 5 days have passed, skip the missed dose and take the next dose on your usual day. If you miss multiple doses, your prescriber may adjust the dose or restart the titration. When unsure, follow the official label or contact your clinic.

Storage and Travel Basics

Store unused Wegovy pens refrigerated at 2°C to 8°C (36°F to 46°F). Keep pens in the original carton to protect from light. Do not freeze. If a pen has been frozen, do not use it. Unopened pens can be kept at room temperature for a limited time per the label; check the current instructions in the prescribing information. During travel, you can store your pens in an insulated bag with cold packs to maintain appropriate temperatures. Keep pens away from direct heat and sunlight. If you have questions about storage or travel, you can message our team during checkout.

Pen Handling and Sharps Disposal

Read the Instructions for Use included with your carton before the first injection. Wash hands. Inspect the pen. Confirm the strength and expiration date. Choose a clean injection site on the abdomen, thigh, or upper arm. For single-use pens, press and hold the device against the skin as directed until the injection completes. Confirm the dose window or indicator shows completion before removing.

After injecting, place the used pen in a puncture-resistant sharps container. Do not throw used pens in household trash or recycling. When the sharps container is full, follow local regulations for disposal or return options. Your pharmacist or local health department can provide guidance.

Benefits

Wegovy helps reduce hunger and supports sustained calorie reduction. Weekly dosing offers convenience compared to daily injections. For patients who meet label criteria and continue lifestyle changes, Wegovy can deliver meaningful weight loss over time. In adults with established cardiovascular disease and obesity or overweight, Wegovy is indicated to reduce the risk of major adverse cardiovascular events when used as prescribed.

Many people appreciate the simplicity of a single weekly dose. The Wegovy pen is designed for straightforward home administration. This can reduce clinic visits and fits active schedules.

Side Effects and Safety

• Nausea
• Vomiting
• Diarrhea
• Constipation
• Abdominal pain
• Headache
• Fatigue
• Indigestion or reflux
• Dizziness
• Injection site reactions

Serious effects are less common but can include pancreatitis, gallbladder problems, kidney issues from dehydration, severe allergic reactions, and changes in vision in people with diabetes. Wegovy carries a boxed warning for thyroid C-cell tumors seen in rodent studies. Do not use if you or a family member has MTC, or if you have MEN 2. If you use insulin or a sulfonylurea, the risk of low blood sugar can increase; your prescriber may adjust other medicines. Seek urgent care for severe stomach pain, persistent vomiting, signs of pancreatitis, symptoms of gallstones, or signs of anaphylaxis.

Drug Interactions and Cautions

Tell your prescriber about all medicines and supplements. Using Wegovy with insulin or sulfonylureas may increase the risk of hypoglycemia. Avoid combining with other GLP-1 receptor agonists. Wegovy can slow stomach emptying, which may affect how quickly some oral drugs are absorbed. Clinical monitoring can help with medicines that need exact levels. Also discuss alcohol use and dehydration risk, as these can worsen stomach side effects or strain the kidneys.

What to Expect Over Time

Many patients experience some nausea or GI changes during the first weeks, especially after dose increases. These effects often improve as your body adjusts. Weight typically changes over months with steady habits. Expect dose steps that gradually increase to the maintenance dose.

Compare With Alternatives

Several prescription options support weight management. Each has a different profile.

• Zepbound® contains tirzepatide. It is a once-weekly injection indicated for adults with obesity or overweight with a weight-related condition.
• Saxenda® 6 Mg Ml contains liraglutide. It is a daily injection for chronic weight management.

Availability and Substitutions

Supply can vary by strength, especially during high demand. If a specific pen is unavailable, your prescriber may recommend a label-appropriate alternative or an adjusted titration plan. Some patients use oral or non-GLP options when injections are not suitable. For example, your clinician may consider Contrave® 8mg 90mg 120 Tablets if appropriate for your health profile.

Patient Suitability and Cost Saving Tips

Wegovy is for patients who meet labeled BMI criteria and can commit to nutrition and activity changes. It may not be suitable if you have a history of MTC or MEN 2, are pregnant, or have certain GI or pancreatic conditions. Always discuss your medical history, including diabetes medications, before starting.

• Ask your prescriber if a 2- or 3-month supply is appropriate to reduce repeat fees.
• Set reminders for weekly injections and for refills to avoid missed doses.
• Rotate injection sites to minimize skin irritation.
• Stay hydrated and eat slowly to help limit GI upset during titration.
• Use the same weekly schedule to build a routine.
