Ozempic vs. Glipizide
See how Ozempic and Glipizide compare on approved uses, dosing, side effects, and cost.
Key Takeaways
Ozempic is a once-weekly injectable GLP-1 drug that also lowers cardiovascular and kidney risk, while glipizide is a low-cost daily pill focused only on blood sugar control.
Ozempic's most common side effects are gastrointestinal, like nausea and vomiting, while glipizide's most common side effects are dizziness, drowsiness, and low blood sugar.
Glipizide costs a fraction of Ozempic's list price, but Ozempic carries added FDA approvals for heart and kidney protection that glipizide does not have.
Ozempic vs. Glipizide Drug Summary
Ozempic
Ozempic (semaglutide) is a GLP-1 receptor agonist used to control blood sugar in adults with type 2 diabetes, alongside diet and exercise. It also carries FDA approval to reduce cardiovascular risk in diabetics with heart disease and to slow kidney disease progression. It's given as a once-weekly injection under the skin.
Glipizide
Glipizide is a sulfonylurea used to control blood sugar in adults with type 2 diabetes, alongside diet and exercise. It works by stimulating the pancreas to release more insulin and has been used since 1984. It's taken as a daily oral tablet, available in immediate-release and extended-release forms.

Ozempic vs. Glipizide Indications
Ozempic
Ozempic is FDA-approved for blood sugar control in type 2 diabetes, and also for reducing cardiovascular risk in diabetics with existing heart disease and slowing chronic kidney disease progression. It is not approved for weight loss, though it's sometimes prescribed off-label for that purpose. It's not for type 1 diabetes.
Blood sugar control in type 2 diabetes, with diet and exercise
Reduces heart attack, stroke, and cardiovascular death risk in known heart disease
Slows kidney damage progression in chronic kidney disease
Off-label use for weight loss in people without diabetes
Glipizide
Glipizide is FDA-approved only for blood sugar control in adults with type 2 diabetes, used alongside diet and exercise. Unlike some newer diabetes drugs, it does not carry cardiovascular or kidney-protection approvals. It's not approved for type 1 diabetes or diabetic ketoacidosis.
Blood sugar control in type 2 diabetes, with diet and exercise
No approved cardiovascular risk-reduction indication
No approved kidney protection indication
Available as immediate-release and extended-release tablets
Ozempic vs. Glipizide Pros and Cons
Ozempic
Ozempic offers added cardiovascular and kidney benefits beyond blood sugar control, but it comes with a higher price tag and a boxed warning for thyroid tumor risk seen in animal studies. Weekly dosing can be convenient, though GI side effects like nausea are common, especially during dose increases.
Pros
Only needs to be taken once a week
Also lowers cardiovascular risk in patients with heart disease
Also slows kidney damage progression in chronic kidney disease
Doesn't directly cause hypoglycemia when used alone
Cons
Requires a weekly injection instead of a pill
GI side effects like nausea and vomiting are common
Boxed warning for thyroid C-cell tumor risk from animal studies
Roughly $935 to $1,043 per month without insurance, before savings programs
Glipizide
Glipizide is inexpensive and simple to take, with decades of clinical use behind it. It doesn't offer the added cardiovascular or kidney protection of newer drugs, and it carries a higher risk of hypoglycemia than non-insulin-releasing options like Ozempic.
Pros
Oral tablet, no injections needed
Roughly $10 to $35 per month, one of the least expensive diabetes drugs
Long track record of safe use dating back to 1984
Available in immediate- and extended-release forms for flexible dosing
Cons
Higher risk of hypoglycemia, especially in elderly or malnourished patients
No added cardiovascular or kidney protection benefit
Sulfonylureas as a class have been linked to cardiovascular mortality concerns
May require more frequent daily dosing than a weekly injection
