If you're exploring options for weight management, you've likely heard about GLP-1 receptor agonists. These medications have become a major topic in the world of obesity treatment.
They offer a new approach by working with your body's natural systems to help control appetite and food intake. But with several different drugs available, how do you know which one might be the right fit for your journey?
This guide will break down the options to help you understand this innovative class of medications and highlight the best GLP-1 medication for weight loss based on current research.
How Do GLP-1 Drugs Work?

GLP-1 drugs mimic a natural hormone called glucagon-like peptide-1, which helps regulate appetite and blood sugar. By activating GLP-1 receptors in the body, these medications influence how you eat, digest, and process glucose.
Their main actions include:
- Reducing appetite by sending fullness signals to the brain
- Slowing stomach emptying, which keeps you satisfied longer and prevents sharp blood sugar spikes
- Improving insulin release when blood sugar is high, making it easier to control glucose levels
Together, these effects help control blood sugar and support weight loss when combined with diet and exercise. Different medications in this class can vary in strength, with some producing greater weight loss in clinical studies.
Which GLP-1 Medications in Canada Can Help You Lose Weight?
If you’re exploring GLP-1s, there are several options available in Canada. Each weight loss medication differs in how it is taken, its effectiveness, and who it is intended for. Here’s a look at the most common choices.
1. Semaglutide (Ozempic, Wegovy, Rybelsus)

Semaglutide is one of the most widely used GLP-1 medications and comes in both injection and tablet form. Each version has its own purpose and potential benefits:
- Ozempic: A weekly injection approved by Health Canada. Its main role is controlling blood sugar, but many patients also see meaningful weight loss as a secondary effect.
- Wegovy: Another weekly injection approved by Health Canada. A study by the National Library of Medicine shows it can show positive results by 15% making it one of the best GLP-1 medications when used under medical guidance.
- Rybelsus: A once-daily oral tablet designed for type 2 diabetes management. It may support modest weight loss, though results are less dramatic compared to injections.
2. Tirzepatide (Mounjaro, Zepbound)

Tirzepatide is a newer GLP-1 that also targets a second receptor called GIP. This dual mechanism makes it especially effective. Here’s how the two versions are used:
- Mounjaro: A weekly injection approved by Health Canada. It improves blood sugar control and often leads to significant weight loss, even though that is not its main purpose.
- Zepbound: A weekly injection approved by Health Canada to be used under supervision. It currently shows the highest results among GLP-1s, with studies from The New England Journal of Medicine reporting reductions of up to 22.5%.
Choosing between the two ultimately depends on personal preferences, dosing considerations, and a clinician’s recommendation.
3. Liraglutide (Victoza, Saxenda)

Liraglutide was one of the earlier GLP-1 options and requires a daily injection instead of a weekly one. It is available in two forms with different goals:
- Victoza: A medication available in Canada in a daily injection format. It is designed for use under the guidance of a licensed healthcare professional.
- Saxenda: A daily injectable product approved in Canada, intended to be used only with a healthcare provider’s supervision and direction.
Who Can Safely Take GLP-1s?

GLP-1 medications can be highly effective, but they are not the right fit for everyone. Doctors in Canada use specific eligibility criteria to decide who can safely take them, while also considering which drug is most appropriate.
Most GLP-1s (including Ozempic, Wegovy, Rybelsus, Mounjaro, Zepbound, Victoza, and Saxenda) share the same baseline criteria. So, you may be a candidate if:
- You are an adult with obesity (BMI of 30 or higher).
- You are overweight (BMI of 27 or higher) and also have a weight-related condition such as type 2 diabetes, high blood pressure, or high cholesterol.
- You have type 2 diabetes and could benefit from better blood sugar control along with weight reduction.
Who Should Avoid GLP-1 Medications?
Even with their proven benefits, GLP-1s are not safe for everyone. Doctors generally do not prescribe them if:
- You have a personal or family history of medullary thyroid carcinoma or MEN2 syndrome.
- You have a history of pancreatitis.
- You are pregnant or breastfeeding, as safety has not been established.
The eligibility rules are the same for all GLP-1s, but their approvals differ. However, the best choice depends on your health profile and goals, and your doctor will guide you to the right option.
How GLP-1 Treatments Are Administered?

One of the biggest differences between GLP-1 medications is how you take them. Some are weekly injections, others are daily, and one even comes as a pill. Knowing the drug administration options can help you choose what feels most practical for your lifestyle.
Let’s look at the different ways GLP-1s are taken:
- Weekly injections: Medications like Ozempic, Wegovy, Mounjaro, and Zepbound are taken once a week using an easy-to-use injection pen. They are usually given in the abdomen, thigh, or upper arm. Many patients prefer these because they mean fewer doses to remember.
- Daily injections: Saxenda and Victoza require a once-a-day shot. While less convenient for some, the daily routine can give others a sense of consistency and structure.
- Oral tablets: Rybelsus is the only GLP-1 available as a pill. It is taken once daily, first thing in the morning with water, followed by a 30-minute wait before eating or drinking. The pill avoids injections but requires strict timing.
Each format has trade-offs. Weekly injections offer convenience, daily injections provide routine, and the oral pill avoids needles altogether. Your doctor will help you decide which option aligns best with your overall health needs and lifestyle.
To complement your treatment, you can also explore losing weight through lifestyle changes that support long-term results.
Here is a table that summarizes the administration frequency and form for the key GLP-1s discussed above:
| GLP-1 Medication | Brand Names | Administration Form | Frequency |
| Semaglutide | Ozempic | Injection pen | Weekly |
| Semaglutide | Wegovy | Injection pen | Weekly |
| Semaglutide | Rybelsus | Orla Tablet | Daily |
| Tirzepatide | Mounjaro | Injection pen | Weekly |
| Tirzepatide | Zeobound | Injection pen | Weekly |
| Liraglutide | Victoza | Injection pen | Daily |
| Liraglutide | Saxenda | Injection pen | Daily |
GLP-1 Side Effects: Which Drugs Hit Harder?

All GLP-1 drugs can cause side effects, mostly digestive, since they slow stomach emptying. Most common side effects include:
- Nausea
- Vomiting
- Diarrhea
- Constipation
- Bloating or stomach discomfort
These effects are usually temporary. Doctors often start patients on a lower dose and gradually increase it to help the body adjust.
What Are Some Rare But Serious Complications?
All GLP-1s may rarely be linked to:
- Pancreatitis
- Liver disease
- Chronic kidney disease
- Heart disease
They are also not recommended for people with a personal or family history of certain thyroid cancers.
Choosing the right medication is about finding the balance between effectiveness and how well your body can manage the side effects of weight loss medication. And, this is why your doctor's guidance is essential.
How Much Do GLP-1 Medications Cost In Canada?
GLP-1 medications are highly effective, but they also come with a significant price tag. In Canada, the monthly cost can vary depending on the specific drug, dosage, and whether you have insurance coverage. To give you a clearer picture, here’s how the prices usually compare:
