Trulicity vs. Glipizide
See how Trulicity and Glipizide compare on approved uses, dosing, side effects, and cost.
Key Takeaways
Trulicity is a once-weekly injectable GLP-1 drug that also lowers cardiovascular risk, while Glipizide is a once-daily oral pill with no proven heart benefit.
Trulicity commonly causes nausea and other GI symptoms, while Glipizide's main risk is hypoglycemia, or low blood sugar.
Glipizide costs a fraction of Trulicity's list price, but Trulicity offers broader benefits including pediatric approval and heart protection.
Trulicity vs. Glipizide Drug Summary
Trulicity
Trulicity (dulaglutide) is a GLP-1 receptor agonist that helps control blood sugar in adults and children age 10 and older with type 2 diabetes. It is injected once a week using a prefilled pen and is also approved to lower the risk of major cardiovascular events in adults with heart disease or multiple risk factors.
Glipizide
Glipizide is an oral sulfonylurea that lowers blood sugar in adults with type 2 diabetes by helping the pancreas release more insulin. It comes as an immediate-release tablet taken once or twice daily, or as an extended-release tablet taken once daily, and is used alongside diet and exercise.

Trulicity vs. Glipizide Indications
Trulicity
Trulicity is FDA-approved to improve blood sugar control in adults and children 10 and older with type 2 diabetes. It also carries an approval to reduce the risk of heart attack, stroke, or cardiovascular death in adults with type 2 diabetes who have heart disease or multiple risk factors. Some clinicians also prescribe it off-label for weight loss in people without diabetes.
Blood sugar control in adults and children 10+
Reduces cardiovascular risk in high-risk patients
Off-label: weight loss in people without diabetes
Glipizide
Glipizide is FDA-approved as an add-on to diet and exercise to control blood sugar in adults with type 2 diabetes. It does not carry a cardiovascular or pediatric indication, but it has been used safely for decades as a first-line or add-on oral therapy. It comes in immediate-release and extended-release forms, giving prescribers dosing flexibility.

Trulicity vs. Glipizide Pros and Cons
Trulicity
Trulicity offers cardiovascular protection and pediatric approval that most oral diabetes drugs lack, but it requires a weekly injection and carries a boxed warning for thyroid tumors seen in animal studies. It has no generic option, so out-of-pocket costs can be high without insurance coverage.
Pros
Reduces cardiovascular risk in high-risk patients
Only needs to be injected once a week
Approved for children as young as 10
Low risk of causing low blood sugar on its own
Cons
Common GI side effects like nausea and diarrhea
Boxed warning for thyroid tumor risk
No generic version available
Roughly $987 to $1,065 per month without insurance, before savings programs
Glipizide
Glipizide is inexpensive, oral, and backed by decades of real-world use, but it carries a real risk of hypoglycemia and offers no cardiovascular or weight benefits. Its low cost makes it a common first-choice oral option for patients on tight budgets.
Pros
Roughly $10 to $35 per month without insurance
Taken as a pill, no injections needed
Decades of established safety data
Widely available as a low-cost generic
Cons
Risk of hypoglycemia, especially in older adults
No proven cardiovascular benefit
Possible weight gain with long-term use
Not approved for children or heart risk reduction
