Head-to-head comparisons of medication uses, side effects, warnings, and more.
Key takeaways
Glyburide / metformin and insulin regular (Humulin R) are both used to manage blood sugar levels in people with Type 2 diabetes. However, they belong to different medication classes and have distinct characteristics. Glyburide / metformin is a combination of a sulfonylurea and a biguanide, taken orally, and is specifically for Type 2 diabetes. It works by increasing insulin release and reducing sugar production and absorption and used to be available as brand-name Glucovance. Humulin R, on the other hand, is a short-acting insulin injected under the skin, used for both Type 1 and Type 2 diabetes. Glyburide / metformin is typically taken once or twice daily with meals, while Humulin R is injected 2 to 3 times daily, 30 minutes before meals. Glyburide / metformin can cause side effects like low blood sugar, diarrhea, and nausea, while Humulin R may lead to low blood sugar and injection site reactions. Glyburide / metformin is prescription-only, whereas Humulin R U-100 is available over-the-counter and by prescription. Additionally, Humulin R comes in different strengths and forms, such as vials and prefilled pens, while glyburide/metformin is available in generic form only.

Summary of Glucovance vs. Novolin N
Summary for Sulfonylurea / Biguanide
Prescription only
Glyburide/metformin is used to manage blood sugar levels in adults with Type 2 diabetes. It works best when taken with a healthy diet and regular exercise. This medication combines a sulfonylurea (glyburide) and a biguanide (metformin). You take it by mouth, typically once or twice daily with meals. Since glyburide/metformin can cause hypoglycemia (low blood sugar), it's important to carry fast-acting sugars like gummy candy or fruit juice to quickly raise your blood sugar if needed. Other common side effects include diarrhea, headache, and nausea. Brand name Glucovance has been discontinued.
Summary for Insulin
Novolin N, a brand name of insulin NPH, is an intermediate-acting insulin. It helps control blood sugar levels in adults and children with Type 1 diabetes or Type 2 diabetes. This type of insulin comes in a vial (Novolin N) and a pen (Novolin N Flexpen). There's also a Novolin N ReliOn brand name. Novolin N is injected under the skin once or twice daily to regulate blood sugar levels. Side effects include low blood sugar (hypoglycemia) and reactions at the injection site.
