If your doctor lets you choose between a weekly injection or a daily oral pill for diabetes, which would you pick? What factors would you consider when deciding which suits you best? If you have an aversion to needles, you’d likely choose the pills, even if it means taking them daily. If not, you’d probably opt for the weekly injections because they’re more convenient. Rybelsus and Trulicity are two popular drugs designed to manage Type 2 diabetes and support weight loss. They have similar effects on the body, but differ in formulations. One comes in tablet form, while the other comes in injection form. IIf you’re facing a similar decision, this guide on Rybelsus vs. Trulicity outlines key factors to help you choose between an oral and injectable option.
Is Trulicity the Same as Rybelsus?
No. While Trulicity and Rybelsus are often part of the same conversations about antidiabetic drugs. They’re similar in some ways, such as their mechanism of action and the fact they’re both GLP-1 agonists indicated for diabetes. However, they also differ in many key ways.
What Is Rybelsus?
Rybelsus is FDA-approved to treat Type 2 diabetes in adults, in combination with diet and exercise. It contains semaglutide and is available in a pill form, taken by mouth every day.
What Is Trulicity?
Trulicity is medically cleared for Type 2 diabetes in adults and children at least 10 years old. It’s also indicated to reduce heart-related complications like death in diabetes patients with cardiovascular comorbidity.
Unlike Rybelsus, Trulicity doesn’t come in a pill form — instead, it’s available as a weekly injection. It contains dulaglutide and is injected under the skin, with or without food.
Both Trulicity and Rybelsus have a similar mechanism of action. They mimic native GLP-1, a hormone that helps control blood sugar, slow digestion, and reduce appetite. Both help lower HbA1c or average blood sugar levels and promote weight loss. Because of these shared effects, people often compare Rybelsus vs. Trulicity to find out which is better.
Rybelsus vs. Trulicity: How Are They Similar and Different
Here’s a comparison of how Rybelsus and Trulicity are similar and different.
| Feature | Rybelsus | Trulicity |
|---|---|---|
| Drug class | GLP-1 receptor agonist | GLP-1 receptor agonist |
| Active ingredient | Semaglutide | Dulaglutide |
| Form | Oral tablet | Injectable pen |
| Dosing frequency | Once daily | Once weekly |
| How to administer | On an empty stomach in the morning with water | At any time of the day, with or without food |
| FDA approval | Type 2 diabetes | Type 2 diabetes |
| Weight loss benefits | Yes (off-label use) | Yes (off-label use) |
| Common side effects | Nausea, diarrhea, abdominal pain | Nausea, vomiting, diarrhea |
| Rare side effect | Pancreatitis, kidney issues | Pancreatitis, thyroid tumors |
| Average cost in the U.S. | $1,163 | $1,123 |
Dosing and Convenience: Daily Pill vs. Weekly Injection?
How you take your medication is just as important as the medication itself. Why? It determines whether you can adhere to your treatment plan. For Rybelsus and Trulicity, the choice is between a needle-free, once-daily pill and a once-weekly injection.
Rybelsus Dosing Schedule
Rybelsus comes in a pill form. It’s often referred to as “Ozempic in pill form” as it contains the same active substance as Ozempic — semaglutide. This oral semaglutide is available in R1 and R2 formulations, with varying recommended dosages. Below is the standard dosing schedule.
| Days | R1 | R2 |
| Days 1 to 30 | 3 mg orally once daily | 1.5 mg orally once daily |
| Days 31 to 60 | 7 mg orally once daily | 4 mg orally once daily |
| Days 61 onward | 7 mg once daily maintenance dose or increase to 14 mg for better glycemic control | 4 mg once daily maintenance dose or increase to 9 mg maximum dose |
During your health check-up, your doctor will assess which formulation best suits your needs. The starting dose for R1 is 3 mg, taken for one month. It increases to 7 mg in the second month and 14 mg from day 61 onward.
R2 has a lower starting dose of 1.5 mg for the first month. It increases to 4 mg in the second month and a maximum dose of 9 mg from the third month onward.
One advantage of Rybelsus is it’s needle-free, but its downside is it requires fasting. Rybelsus is taken in the morning on an empty stomach with only water. If you’re sensitive to stomach-related side effects, popping a pill on an empty stomach may lead to more intense adverse reactions.
Trulicity Dosing Schedule
| Treatment timeline | Dose | Notes |
| Weeks 1-4 | 0.75 mg | Starting dose |
| Weeks 5-8 | 1.5 mg | Standard maintenance dose for most people |
| Weeks 9-12 | 3 mg | If additional blood sugar or weight control is needed |
| Weeks 13-16 | 4.5 mg | Maximum approved dose |
Trulicity is administered once weekly via a subcutaneous injection in the stomach area, thigh, or upper arm. Patients typically start with the lowest dose of 0.75 mg during the first month of treatment. It increases to 1.5 mg in the second month, 3 mg in the third month, and 4.5 mg in the fourth month.
Trulicity’s once-weekly injection is a major benefit because it fits easily into most people’s routines and requires fewer medication reminders. While the weekly shot offers convenience, it’s not the best choice for those who dislike needles.
When comparing Rybelsus vs. Trulicity, one key factor to consider is how easily they fit into your lifestyle.
Which Works Better for Diabetes?
No study has directly compared the effectiveness of Rybelsus vs. Trulicity for lowering blood sugar levels. However, clinical trials have revealed that Rybelsus lowers HbA1c more effectively than Trulicity, especially at the maximum 14 mg dose.
In a 26-week trial, patients with Type 2 diabetes were randomly treated with Rybelsus 7 mg, 14 mg, or a placebo. After the treatment, those who received Rybelsus 7 mg and 14 mg lowered their HbA1c levels by 1.2% and 1.4%, respectively. Clinically speaking, these are significant changes from the baseline HbA1c rate of 8%. Meanwhile, people in the placebo group reduced their HbA1c by only 0.3%.
In a clinical trial of Trulicity, which also lasted 26 weeks, patients with Type 2 diabetes were randomly given 0.75 mg, 1.5 mg of Trulicity, or 1500-2000 mg of metformin — an antidiabetic medication. After the treatment, those on 0.75 mg and 1.5 mg of Trulicity reduced their HbA1c levels by 0.7% and 0.8%, respectively. Meanwhile, patients on metformin saw a 0.6% decrease in their HbA1c levels.
So, which works better for diabetes? Clinical trials suggest Rybelsus — though individual results may vary based on health history and lifestyle factors.
Which Makes You Lose More Weight?
Both Trulicity and Rybelsus offer weight loss as a secondary benefit. Based on FDA-overseen studies, Rybelsus is also more effective than Trulicity in promoting weight loss.
In the same 26-week clinical trial on Rybelsus, patients on 7 mg and 14 mg of oral semaglutide lost 2.3 kg and 3.7 kg of body weight, respectively. Those in the placebo group lost only 1.4 kg.
Also in the same 26-week trial on Trulicity, participants on 0.75 mg and 1.5 mg of Trulicity lost 1.4 kg and 2.3 kg of body weight, respectively. Patients on metformin lost 2.2 kg.
If your goal is both weight loss and blood sugar control, Rybelsus may be a better option than Trulicity. Your doctor will help determine which treatment is best suited for you, based on your preferences, needs, and tolerance to side effects.
Which Has Fewer and Milder Side Effects?
If you dig into Rybelsus vs. Trulicity side effects and which drug causes fewer side effects, you’ll probably get conflicting answers. That’s because drug reactions can vary from person to person.
Since they belong to the same class of drugs, Rybelsus and Trulicity cause nearly similar common and serious side effects. At least 5% of users of both drugs may experience the following typical symptoms during treatment:
-
- Nausea
- Decreased appetite
- Vomiting,
- Constipation
- Abdominal pain
- Diarrhea
Some serious risks include:
-
- Thyroid C-cell tumors
- Severe low blood sugar
- Hypersensitivity reactions
- Acute kidney injury
- Pulmonary aspiration
- Diabetes-related vision loss
- Acute gallbladder disease
These serious side effects of Rybelsus and Trulicity rarely occur. If you experience symptoms associated with any of the above conditions, please notify your doctor immediately.
Which Is More Affordable?
Another major consideration is which prescription is more pocket-friendly in the long term. Rybelsus and Trulicity can be expensive for uninsured and underinsured individuals. In the U.S., the average cost of Rybelsus pills is $1,163, while the price of Trulicity pens is $1,123.
If you meet the criteria, such as income level, you may qualify for patient assistance or manufacturer savings programs to afford your monthly medications. Otherwise, you can purchase your prescription from online pharmacies that offer more affordable brand-name medications.
Canada-based online pharmacies, such as Buy Canadian Insulin, allow you to save up to 90% on your medications. In Canada, you can purchase a bottle of Rybelsus tablets for $298 and get Trulicity pens for $282. Medications in Canada are generally more cost-effective than in the U.S., allowing you to continue treatment for several months to years.

Switching from Trulicity to Rybelsus
If Rybelsus or Trulicity isn’t available in your local pharmacy, your doctor may recommend a similar-acting medication. Here are some alternatives:
- Ozempic: Contains semaglutide and is approved for diabetes
- Mounjaro: Contains tirzepatide and is also medically cleared for diabetes
- Jardiance: Contains empagliflozin, comes in a tablet form, and is also approved for diabetes
When switching from Trulicity to Rybelsus or vice versa, consider the following tips.
- 1
Remember the Timing
Rybelsus is taken daily, while Trulicity is injected weekly. Mind the dosing schedule to ensure a smooth transition. - 2
It’s Okay to Start Slow
Start with the lowest dose of 3 mg, taken daily for 30 days. This initial dose is intended to help your body adjust to the medication — not to induce weight loss. During the first month of treatment, expect slight to no changes in your body size. - 3
Take the Medication as Prescribed
Rybelsus should be taken on an empty stomach with no more than 4 ounces of water. You must wait at least 30 minutes before drinking or eating anything else. - 4
Monitor Changes in the Treatment
Whether you experience blood sugar fluctuations, side effects, or weight loss, track your treatment progress and notify your doctor if anything feels off.
Rybelsus or Trulicity? It Depends on Your Needs
From classic insulin to newer GLP-1 drugs, the options for treating diabetes are numerous, which can feel overwhelming. Keep in mind that the right medication should meet your needs, fit your lifestyle, and work effectively for you.
If you want to lose weight and control blood sugar levels, popping a Rybelsus pill daily may suit you better. However, if you prefer a more convenient approach with fewer medication reminders, a once-weekly injection of Trulicity may be a good fit.
You can compare Rybelsus vs. Trulicity for diabetes, but the best choice ultimately depends on individual factors, such as dosing schedule, budget, and health goals. If you’re unsure which to choose, your doctor can help you find the option best suited to your needs.
