Trulicity (dulaglutide) is a medication commonly prescribed to manage type 2 diabetes. It belongs to a class of drugs known as glucagon-like peptide-1 (GLP-1) receptor agonists. Trulicity works by mimicking the effects of the natural hormone GLP-1, which helps regulate blood sugar levels. While Trulicity can be highly effective in controlling diabetes, it’s essential to be aware of potential side effects that may accompany its use.

Understanding Common Trulicity Side Effects

Like any medication, Trulicity can cause side effects, although not everyone experiences them. Here are some of the most common side effects associated with Trulicity:

Gastrointestinal Symptoms

  • Nausea: Nausea is one of the most frequently reported side effects of Trulicity, particularly during the initial weeks of treatment.
  • Diarrhea: Some individuals may experience diarrhea as a side effect of Trulicity, which can range from mild to severe.
  • Vomiting: Vomiting may occur in some patients, especially when starting Trulicity or when the dosage is increased.

Injection Site Reactions

  • Redness or Irritation: Trulicity is administered via injection under the skin, which can sometimes cause redness, itching, or irritation at the injection site.
  • Bruising: Bruising may occur at the injection site, although it is typically mild and resolves on its own.


  • Low Blood Sugar: Trulicity can lower blood sugar levels, leading to hypoglycemia (low blood sugar). Symptoms of hypoglycemia include dizziness, shakiness, sweating, and confusion.

Weight Loss

  • Appetite Suppression: Some individuals may experience a decrease in appetite while taking Trulicity, which can lead to weight loss.

Less Common Trulicity Side Effects

While less common, some individuals may experience the following side effects when using Trulicity:


  • Pancreatic Inflammation: In rare cases, Trulicity may increase the risk of pancreatitis, characterized by severe abdominal pain, nausea, and vomiting.

Thyroid Tumors

  • Thyroid Cancer: Long-term use of Trulicity in animal studies has been associated with an increased risk of thyroid tumors. However, more research is needed to determine if this risk applies to humans.

Allergic Reactions

  • Hypersensitivity: Some individuals may experience allergic reactions to Trulicity, including itching, rash, or difficulty breathing. Severe allergic reactions, though rare, require immediate medical attention.

Managing Trulicity Side Effects

If you experience side effects while taking Trulicity, there are several steps you can take to manage them effectively:

Communicate with Your Healthcare Provider

  • Open Communication: Inform your healthcare provider about any side effects you experience while taking Trulicity. They can offer guidance and may adjust your treatment plan if necessary.

Monitor Blood Sugar Levels

  • Regular Monitoring: Monitor your blood sugar levels regularly, especially during the initial weeks of Trulicity treatment. This can help prevent episodes of hypoglycemia and ensure optimal diabetes management.

Stay Hydrated

  • Hydration: Drink plenty of water to stay hydrated, especially if you experience gastrointestinal side effects like nausea or diarrhea.

Injection Site Care

  • Proper Technique: Ensure proper injection technique and rotate injection sites to minimize the risk of injection site reactions.

Trulicity is a valuable medication for managing type 2 diabetes, but it’s essential to be aware of potential side effects. By understanding the possible adverse reactions and how to manage them, you can work with your healthcare provider to optimize your treatment plan and maintain good health. If you have concerns about Trulicity side effects or experience severe symptoms, consult your healthcare provider promptly for guidance and support.
