SUMMARY

Ozempic® and Rybelsus® contain the same active ingredient: semaglutide. The biggest difference is how they're administered.

Ozempic® is administered as a subcutaneous injection, while Rybelsus® is taken as an oral tablet.

Because they contain the same active ingredient, they share some similarities. However, the two products have different formulations, administration instructions and prescribing considerations.

Understanding these differences can help you have a more informed conversation with your practitioner or pharmacist.

If you've come across both Ozempic® and Rybelsus®, you may be wondering why they're being compared.

The answer is straightforward: they contain the same active ingredient, semaglutide, but come in different forms.

Ozempic® is an injectable product, while Rybelsus® is an oral tablet.

That difference may seem simple, but it affects how each medication is taken and incorporated into a person's prescription routine.

Ozempic® vs. Rybelsus® at a glance

So, while the two products share the same active ingredient and medication class, their formulations and administration are different.

What do Ozempic® and Rybelsus® have in common?

The most important similarity is that both contain semaglutide.

Semaglutide belongs to a class of medications called GLP-1 receptor agonists.

GLP-1 is a hormone naturally produced by the body that is involved in processes such as insulin and glucagon regulation and digestion.

How does semaglutide work?

Once in the body, semaglutide activates GLP-1 receptors. These receptors are involved in regulating insulin and glucagon and in slowing the movement of food through the stomach.

One important feature of semaglutide is that its effect on insulin and glucagon is glucose-dependent, meaning its activity changes depending on blood glucose levels.

Why does the formulation matter?

Although the active ingredient is the same, Ozempic® and Rybelsus® don't deliver semaglutide in the same way.

Ozempic® is designed for injection and has a formulation that allows semaglutide to remain in the body for an extended period, supporting once-weekly administration. 

Rybelsus® uses an oral formulation designed to allow semaglutide to be absorbed through the digestive system, which is why it has specific instructions around fasting, water and the timing of food and other medications.

What is the biggest difference between Ozempic® and Rybelsus®?

The biggest practical difference is how you take them.

Ozempic® is administered by subcutaneous injection once weekly.

Rybelsus® is taken as an oral tablet once daily.

How do you take Rybelsus®?

Rybelsus® has specific instructions for how and when it should be taken.

According to the Canadian product information, Rybelsus® should be taken on an empty stomach after at least 8 hours of fasting, with a small amount of water. Food, beverages other than water and other oral medications can affect how the medication is absorbed.

After taking Rybelsus®, you should wait at least 30 minutes before eating, drinking or taking other oral medications. (Health Products Canada)

These instructions are an important part of using the medication correctly.

If you are prescribed Rybelsus®, follow the instructions provided by your practitioner and pharmacist.

How do you take Ozempic®?

Ozempic® is administered once weekly by injection under the skin. It can be injected into the abdomen, thigh or upper arm, and the injection site should be rotated rather than using the exact same spot each time.

Unlike Rybelsus®, Ozempic® can be taken at any time of day, with or without food. It's generally taken on the same day each week, although the day can be changed as long as there is at least 48 hours between doses.

If you're using the pen for the first time, your practitioner, pharmacist or another healthcare professional can show you how to administer it correctly.

The medication should be used according to the instructions provided with your prescription. Do not change the dose or schedule on your own.

Which is easier to use: Ozempic® or Rybelsus®?

There isn't one answer for everyone.

For some people, a weekly injection may fit more easily into their routine. For others, taking a tablet may feel more convenient.

But convenience isn't the only consideration when choosing a prescription medication. Your practitioner can consider your individual circumstances and determine what treatment approach is appropriate.

Are Ozempic® and Rybelsus® interchangeable?

Although both contain semaglutide, you should not switch between Ozempic® and Rybelsus® on your own.

They have different formulations, administration schedules and instructions.

If you're considering changing from one to the other, speak with your practitioner. They can determine whether a change is appropriate and provide instructions for managing the switch.

Your pharmacist can also answer questions about your prescription and administration routine.

Can Ozempic® and Rybelsus® be taken together?

No. Because both products contain semaglutide, they should not be taken together unless specifically directed by a practitioner.

If you're currently taking one and have been prescribed the other, clarify with your practitioner or pharmacist how your medication regimen should be managed.

What about side effects?

Because Ozempic® and Rybelsus® contain the same active ingredient, their safety profiles have similarities.

However, the full safety information for each product should be reviewed in its respective Canadian product monograph.

If you're prescribed either medication, your practitioner or pharmacist can explain the relevant precautions and what to do if you experience a concerning reaction.

Rather than relying on an online list of side effects, speak with your pharmacist if you have questions about a specific symptom or concern.

Are Ozempic® and Rybelsus® equally effective?

This is more complicated than simply comparing the two products and declaring one better.

Both contain semaglutide, but they are different formulations with different administration routes. Clinical studies have evaluated each product under specific conditions, doses and study populations.

Results from one clinical trial should not be interpreted as a guarantee of how either medication will work for an individual.

If you're comparing the two because you're considering a change in your prescription, your practitioner can explain how the available options fit your circumstances.

How much do Ozempic® and Rybelsus® cost?

There isn't one fixed Canadian price for either medication.

Your cost can depend on:

• The specific product and quantity dispensed
• The pharmacy
• Applicable dispensing or professional fees
• Insurance coverage
• Public drug coverage
• Eligibility requirements

At Pocketpills, the current listed price is $139 for Ozempic® and {ADD COST} for Rybelsus®.

Prices may change and may vary based on your prescription, coverage and applicable fees. Check the current price before filling your prescription.

Are generic versions of Ozempic® or Rybelsus® available?

Canada's semaglutide market has changed in 2026, with generic semaglutide products now authorized and marketed. Health Canada's Drug Product Database lists several semaglutide products separately from the brand-name products. (Health Products Canada)

However, it's important not to assume that every generic semaglutide product is interchangeable with every brand-name semaglutide product.

The formulation, strength, route of administration and authorized uses can differ.

If you're interested in a generic semaglutide product, speak with your pharmacist about what is available and appropriate for your prescription.

Which one is right for you?

There isn't one medication that is automatically right for everyone.

A practitioner may consider factors such as:

• Your health history
• Other medications you're taking
• How you prefer to manage your prescription
• Your ability to follow the administration instructions
• Your insurance coverage
• The available prescription options
• Other individual health considerations

The fact that one medication is an injection and the other is a tablet doesn't automatically make one better than the other.

The right choice depends on the individual prescription and circumstances.
