This article discusses everything you need to know about how sulfonylureas work for type 2 diabetes and what to expect when taking the drug.
Effect of Sulfonylureas on Type 2 Diabetes
People with type 2 diabetes must manage their blood sugar levels because their bodies do not respond to insulin. As a result, sugar levels build up in the blood and cause health issues.
Sulfonylureas stabilize blood sugar by helping the pancreas create more insulin. Sulfonylureas stimulate pancreatic β-cells, the cells in the pancreas that produce and release insulin. Increased insulin levels in the body improve the transfer of blood sugar into cells. Sulfonylureas also reduce the amount of insulin cleared from the body by the liver, which prevents high blood sugar.
Sulfonylureas vs. Metformin
Metformin is another drug that treats diabetes. It works similarly to sulfonylureas by helping the body handle insulin more appropriately. However, Metformin belongs to a different class of medicines known as biguanides. Biguanides work by increasing how well insulin works as opposed to keeping more insulin in the body.
Although both drugs treat type 2 diabetes, Metformin is often the first-choice therapy and is a better choice for people with health complications such as reduced kidney function.
In some cases, the two drugs will be taken in a combinational approach to help better control diabetes and blood sugar levels.
The safety level of both medications depends highly on a person’s health history, any complications or health issues they have outside of type 2 diabetes, and their healthcare provider’s recommendations. That said, some research has found that taking sulfonylureas can increase the risk of cardiovascular complications over metformin use.
Brand-Name and Generic Types
Many different medications fall under the umbrella of sulfonylureas.
Hypoglycemia (dangerously low blood sugar) A worsening insulin response Weight gain Nausea Feeling full in the upper abdomen Heartburn Light-colored stools Pain in the upper-right area of the stomach Unusual bleeding or bruising Diarrhea Sore throat Swelling of the eyes, face, lips, tongue, or throat Skin reactions that mimic allergies Sensitivity to the sun Severe skin inflammation that covers the entire body An impaired liver function could lead to jaundice, hepatitis, and liver failure Changes in how the heart functions An increased risk of heart disease and stroke
Drug Interactions
Some medications should not be taken at the same time as sulfonylureas or hold a higher risk for adverse effects, such as:
Aspirin Medications that reduce blood pressure, such as beta-blockers Clarithromycin, an antibiotic Colesevelam, a cholesterol-lowering drug Antifungal medications Non-steroidal anti-inflammatory drugs (NSAIDs), such as Advil Quinolone antibiotics Sulfamethoxazole, an antibiotic Topiramate, an anti-seizure medication Warfarin, a blood thinner
Summary
Sulfonylureas are a class of type 2 diabetes drugs. They are considered safe and effective and stabilize blood sugar by increasing insulin production. Though sulfonylureas are effective, they are not always the first choice when treating type 2 diabetes. Typically, that is metformin. However, the drug given to you will depend highly on your health history and how you respond to medications.
All medications have side effects. Some are more severe than others and require monitoring. If you experience side effects, it’s essential to contact your healthcare provider. They can determine if the medication is still suitable for you based on your experience, how well your blood sugar is managed, and what other drugs or supplements you are taking.
A Word From Verywell
Type 2 diabetes isn’t always easy to cope with, but it can be managed effectively with medications such as sulfonylureas. They are generally considered safe, so if your healthcare recommends them, it’s probably for a good reason.
Managing diabetes early on will significantly reduce your risk of complications caused by untreated high blood sugar levels. If you are unsure about taking this drug, speak to your healthcare provider for more information about whether it’s right for you.
