A Trulicity shot is a once-weekly injectable medication used to manage blood sugar levels in adults with type 2 diabetes. Each Trulicity contains Dulaglutide, a GLP-1 receptor agonist that works by mimicking a natural hormone in your body to regulate insulin and reduce glucose levels after meals.
If you have been recently prescribed this medication or are just researching your options, you are likely wondering how the Trulicity shot works, what to expect from it, and whether it is right for you.
This article walks you through everything, from how each Trulicity is given to its side effects, how it compares to similar medications, and what results you can realistically expect. We also cover how 365 Script Care, a prescription referral service with a licensed contracted pharmacy department, can help US patients access this medication.
What Is a Trulicity Shot?
It is a pre-filled, single-use autoinjector pen that delivers Dulaglutide, a GLP-1 receptor agonist, into the skin. It is approved for adults with type 2 diabetes to improve blood sugar control alongside a healthy diet and exercise.
It is given once a week on the same day, at any time of day, with or without food. The pen is designed to be simple to use. You press it against your skin, click the button, and the needle inserts and withdraws automatically. Most people inject the Trulicity shot into the stomach, thigh, or upper arm.
It comes in four dose strengths: 0.75 mg, 1.5 mg, 3 mg, and 4.5 mg. Doctors usually start patients on the lowest dose and increase it gradually based on how the body responds.
How Does the Trulicity Shot Work?
It works by activating GLP-1 receptors in the pancreas. GLP-1 is a hormone that is naturally released when you eat. It stimulates these receptors, several things happen at once.
First, the pancreas releases more insulin in response to blood sugar. Second, the liver is told to slow down its own glucose production. Third, the stomach empties food more slowly, which helps prevent sharp blood sugar spikes after meals. This combination of effects makes the Trulicity effective at keeping blood sugar levels stable throughout the day.
Because the Trulicity shot also slows digestion, many people feel fuller for longer after eating, which can naturally reduce calorie intake over time.
Trulicity Shot Dosing and Schedule
One of the biggest advantages of the Trulicity shot is how simple the dosing schedule is. Unlike some diabetes medications that must be taken multiple times a day, the Trulicity shot only needs to be given once a week.
| Dose Strength | Common Use |
| 0.75 mg | Starting dose for new patients |
| 1.5 mg | Standard maintenance dose |
| 3 mg | Increased dose for better control |
| 4.5 mg | Maximum dose for additional A1C reduction |
Most doctors start with 0.75 mg for the first four weeks to let the body adjust. If blood sugar targets are not reached, the dose can be increased to 1.5 mg or higher. The maximum dose for the Trulicity shot is 4.5 mg per week.
If you miss a Trulicity shot, take it as soon as you remember, but only if your next scheduled dose is at least three days away. If it is closer than that, just skip the missed dose and resume your regular weekly schedule.
What to Expect from a Trulicity Shot
When you first start the Trulicity shot, your body needs time to adjust. Some side effects are common in the first few weeks, especially nausea. This usually improves as your body gets used to the medication.
Common side effects from the Trulicity shot include:
- Nausea, especially after the first few injections
- Diarrhea or upset stomach
- Reduced appetite
- Vomiting in some patients
- Injection site reactions such as redness or minor discomfort
Most people find that nausea from the Trulicity fades after a few weeks. Eating smaller meals and avoiding fatty foods right after each Trulicity shot can help reduce stomach discomfort.
Serious side effects are less common but include pancreatitis, kidney problems, and in rare cases, a type of thyroid tumor. Patients with a personal or family history of medullary thyroid cancer are typically advised to avoid this class of medication. Always discuss your full medical history with your doctor before starting the Trulicity shot.
Trulicity Shot for Weight Loss
Many patients and doctors notice that weight loss often follows treatment with the Trulicity shot. While Trulicity is not officially labeled as a weight loss drug, it is prescribed off-label for that purpose in some cases and often results in moderate weight reduction in type 2 diabetes patients.
The reason the Trulicity shot supports weight loss is connected to how it slows gastric emptying. When food moves through the stomach more slowly, you stay full longer, eat less, and naturally reduce your calorie intake over time.
Clinical studies have shown that patients using the Trulicity shot lost an average of four to ten pounds over several months, depending on the dose and lifestyle factors. The 4.5 mg dose tends to produce greater weight loss than the 0.75 mg starting dose.
Weight loss with the Trulicity shot is gradual and steady rather than dramatic. Pairing the injection with a healthy diet and regular physical activity leads to better results. The Trulicity shot works best as part of a wider lifestyle effort, not as a standalone weight loss tool.

Trulicity Shot vs. Other GLP-1 Medications
If you are comparing the Trulicity shot to other options, it helps to see how they differ in practical terms.
| Feature | Trulicity Shot | Ozempic | Wegovy | Saxenda |
| Active ingredient | Dulaglutide | Semaglutide | Semaglutide | Liraglutide |
| Injection frequency | Once weekly | Once weekly | Once weekly | Daily |
| Primary use | Type 2 diabetes | Type 2 diabetes | Weight management | Weight management |
| Auto-injector pen | Yes | No | No | No |
It uses a fully automated injector, which many patients prefer because the needle is never visible. Ozempic requires manual injection with a separate pen needle. Both are weekly injections, but the experience of giving each one is different.
Ozempic uses Semaglutide, which has shown slightly stronger blood sugar reduction in head-to-head studies. However, it is often better tolerated by people who are new to injections due to its easier delivery device.

Frequently Asked Questions
Is Trulicity the Same as Ozempic?
No, Trulicity and Ozempic are not the same medication. Trulicity contains Dulaglutide while Ozempic contains Semaglutide. Both are once-weekly GLP-1 receptor agonist injections for type 2 diabetes, but they differ in active ingredient, dosing pens, and overall potency. Ozempic has shown slightly stronger A1C reduction in studies, but many patients prefer the Trulicity shot for its simpler auto-injector design.
Is a Trulicity Injection for Weight Loss?
Trulicity is not officially approved as a weight loss medication, but it does support weight reduction in many patients. Because the Trulicity shot slows digestion and reduces appetite, patients often lose weight as a side effect of blood sugar management. Clinical data shows an average loss of four to ten pounds over several months. If weight loss is your primary goal, a doctor may suggest a dedicated weight management medication instead.
Read about Wegovy reviews to see how a dedicated weight loss injection compares.
How Long Does One Injection of Trulicity Last?
One Trulicity shot lasts seven days, which is why it is dosed once weekly. Dulaglutide has a long half-life that allows it to stay active in the body throughout the week. This means blood sugar benefits are sustained between doses without needing daily injections.
Which Has Worse Side Effects, Trulicity or Ozempic?
Both medications share similar side effects, but Ozempic tends to cause more intense nausea at higher doses. The Trulicity is generally considered slightly better tolerated for new patients. Nausea, diarrhea, and reduced appetite are common with both. Serious side effects are rare for both medications. Individual responses vary, so what bothers one person may not affect another. Always speak with your doctor about your specific health history before choosing between the two.
Can You Lose 20 Pounds on Trulicity?
Losing 20 pounds on Trulicity alone is unlikely for most patients. Clinical trials show an average weight loss of four to ten pounds with the Trulicity shot when combined with diet and exercise. Some patients may lose more, but significant weight loss of 20 pounds or higher is more commonly associated with higher-dose weight management medications like Wegovy or Zepbound. You can learn more about how Zepbound works for weight loss if you are looking for stronger results.
