Sulfonylurea Agents: "Oral Hypoglycemic Agents"

Why do I need Sulfonylurea agents?

Sulfonylurea agents (or oral hypoglycemic agents) are one of six types of diabetes pills currently available to treat type 2 diabetes.

Remember, the cornerstone of diabetes control remains unchanged: it is important to follow a meal plan and get plenty of physical activity. Diabetes pills are simply another tool to help you manage your blood glucose.

How do sulfonylurea agents work?

Sulfonylurea agents work to lower blood glucose by:

Guidelines for use:

What should I do if I forget to take my dose?

If you have forgotten to take your diabetes pills, take them, provided it has been less than 2 hours from your dosage time. Write down that you delayed a dose in your record book. If it has been more than 2 hours, contact your healthcare provider. Do not take 2 doses at the next meal unless otherwise instructed. If you skip a dose, note it in your record book.

Can I take sulfonylurea agents with other medications?

Most medications interact safely with the newer sulfonylurea agents. However, always remind your healthcare provider what medicines you are taking and when there is a change in your medications. This will help ensure the combinations are safe. Ask if the new medication will affect your diabetes.

What are the side effects of sulfonylurea agents?

Hypoglycemia or low blood glucose is the most common side effect of the sulfonylurea agents.

Other side effects, although uncommon, are listed below. Be sure to contact your healthcare provider if any of the following problems occur while you are taking your sulfonylurea agent:

How will I know if it is working?

Check your blood glucose at the times specified by your healthcare provider. If your blood glucose or A1C is within target most of the time, the dose is working. If not, review the amount and types of food eaten or if you have forgotten to take the prescribed dose of your medication. If blood glucose remains high, contact your healthcare provider. A change in dose may be needed.

New medications

Other new medications that work very similar to sulfonylureas by helping the pancreas make more insulin are:

These medication can also cause hypoglycemia. One advantage of taking these is that if a meal is skipped, the dose can be skipped.
