Trulicity is a once-weekly injectable medication designed for adults with type 2 diabetes, approved to help manage blood sugar levels more effectively. 

It not only helps with managing diabetes but also supports weight loss and helps prevent stroke, heart attacks, and premature death in those with preexisting heart conditions. 

But what are the side effects of this medication, and how will it impact your daily life? This article will investigate everything you need to know about Trulicity’s side effects

How does Trulicity work?

Trulicity, a medication containing the active ingredient dulaglutide, is not a form of insulin nor does it replace insulin. However, it is frequently used alongside insulin to improve diabetes management. 

The medication works by attaching to specific receptors on pancreatic cells, prompting the release of more insulin, which helps lower blood sugar levels

Additionally, Trulicity reduces glucagon production in the liver, preventing spikes in blood sugar after meals and enhancing insulin sensitivity. It also slows digestion, which suppresses appetite and can lead to weight loss over time.

A few rare but serious and/or long-term side effects have been noted, including:

  • Acute pancreatitis
  • Severe allergic reaction
  • Diabetic retinopathy (the medicine can worsen diabetic retinopathy if you already have the condition)
  • Gallbladder disease
  • Impaired kidney function
  • Medullary thyroid carcinoma (MTC, a type of thyroid cancer)

The FDA has also issued a black box warning linking Trulicity to an increased risk of thyroid cancer.

People with conditions like gastroparesis or chronic kidney disease (CKD) should consult their doctor before using Trulicity, as it may worsen these conditions.

If side effects last for more than a few weeks or become debilitating, affecting work, school, or social life, discuss with your doctor the possibility of adjusting the dosage or switching to an alternative medication.

How long do Trulicity side effects last?

Nausea is the most commonly reported side effect of Trulicity, affecting 8 to 29 percent of users, according to the manufacturer. While this side effect generally resolves within the first two weeks for most people, it can last longer in some cases.

Additionally, fewer than 2 percent of users find it necessary to discontinue Trulicity due to nausea. 

It’s important to note that other side effects such as diarrhea, vomiting, and decreased appetite may also occur, but these typically decrease as the body adjusts to the medication over a similar timeframe. If side effects persist or worsen, consult your healthcare provider.

How can you mitigate the side effects of Trulicity? 

Managing the side effects of Trulicity involves several strategies to maintain comfort and safety. If you experience nausea, vomiting, or diarrhea, it’s important to stay hydrated. Drinking plenty of water and consuming electrolytes, such as those found in coconut water, can help.

Monitoring your blood sugar levels is also essential; if they are consistently too high, you may be at risk for diabetic ketoacidosis (DKA), a potentially life-threatening condition. 

Similarly, low blood sugar can be dangerous, especially if you are also taking insulin, and requires careful management.

To reduce nausea, eat bland foods like toast, rice, bananas, and applesauce, and ensure you drink clear liquids. If nausea prevents you from keeping food or drink down, seek medical attention immediately.

Eating smaller, more frequent meals can help manage gastrointestinal symptoms. Stop eating when you are full, even if the amount seems less than usual. 

For persistent nausea, consider over-the-counter remedies like Dramamine (dimenhydrinate), or discuss prescription options like Zofran (ondansetron) with your doctor.

Does taking more Trulicity make the side effects worse? 

Increasing the dose of Trulicity can indeed raise the likelihood of experiencing side effects. 

Clinical studies reveal that higher doses result in increased side effects. For instance, about 16 percent of participants in one study reported worsened nausea, leading approximately 1 percent to discontinue the medication.

Therefore, it is important to stick strictly to your doctor’s prescribed dosage of Trulicity, particularly when starting the medication. Your doctor will carefully adjust your dose based on how your body responds, ensuring the best balance between effectiveness and tolerability.

Do you have to take Trulicity with food? 

No, Trulicity does not require food when taken, which differs from many insulin treatments. 

It gradually lowers blood sugar levels without causing the acute lows that can occur with insulin. Consistency in taking your dose is crucial, so it’s best to take the medicine at a time that’s easy for you to remember.

However, if you experience nausea after taking your dose, eating a small amount of food beforehand might help reduce this discomfort, although it’s not necessary.

How do I know if I should stop taking Trulicity? 

If Trulicity’s side effects become debilitating and disrupt your daily life, discuss this with your doctor. Should you both decide to stop the treatment, your doctor will likely taper your dose gradually over several weeks, rather than discontinuing it abruptly.

Patience is important if you’re considering stopping due to a lack of immediate improvements in blood sugar levels or weight loss. It’s common for these changes to take time with any medication, including Trulicity. 

Typically, doctors recommend allowing several months for the medication to achieve its full effect before deciding to discontinue it.

Who should not use Trulicity? 

Trulicity is not suitable for everyone. People allergic to dulaglutide, the active ingredient in Trulicity, should avoid it. It is also contraindicated for those with a personal or family history of medullary thyroid carcinoma (MTC) or multiple endocrine neoplasia.

Additionally, Trulicity is not approved for children under 18 years old unless prescribed by a physician. It is not recommended for individuals who are pregnant, planning to become pregnant, or breastfeeding.

If you have chronic kidney disease (CKD) or gastroparesis, speak with your doctor before using Trulicity, as it may worsen these conditions. Also, Trulicity is not designed to treat prediabetes or type 1 diabetes.

Are there alternatives to Trulicity? 

If you’re experiencing negative side effects with Trulicity, it’s important to consult your doctor about possible alternative medications that might be better tolerated. Some potential alternatives to Trulicity include:

  • Ozempic (semaglutide) and Ryebelsus (semaglutide): Both contain the same active ingredient but are administered differently. (Learn more in: Trulicity vs. Ozempic: Which Medication Is Right for You?)
  • Mounjaro (tirzepatide) and Victoza (liraglutide): These medications also aim to improve blood sugar management in type 2 diabetes.
  • Farxiga (dapagliflozin), Jardiance (empagliflozin), and metformin: These offer additional mechanisms of action and may be suitable depending on your health profile and specific needs.
