What is glyburide? How should you take this medication? This guide will break down everything you need to know about glyburide and how to use it.
What Is Glyburide (Micronase)
Glyburide (Micronase) is a drug that comes in the form of tablets. Glyburide drug classification is called sulfonylureas. It is mostly used for treating diabetes. Most often, sulfonylureas contain such active substances as Glucotrol, tolazamide, glimepiride, and chlorpropamide.
Micronase is often combined with a healthy diet and exercise to achieve the best results. It helps improve blood sugar control, which is one of the best ways to keep the disease from worsening.
Patients with type 2 diabetes suffer from high levels of glucose in their blood. Due to that, the pancreas isn’t capable of producing enough insulin. Micronase reduces the glucose levels and stimulates the organism to produce more insulin. As a result, the body gets enough insulin. Even though this process hasn’t been fully analyzed and studied, the medicine is proven to be effective in fighting the high levels of glucose in a patient’s blood.
Glyburide might be used for a variety of purposes, and not only for treating diabetes. However, it is not used for treating diabetes type 1. Treatment should be discussed personally with your doctor. Do not take this drug on your own. Your doctor is supposed to tell you what is glyburide and how you should take it. The treatment with the medicine should appear on your diabetic identification card.
Use Of This Medication
Glyburide, along with some other medication, healthy diet, and exercise, is used to treat type 2 diabetes. This drug can be only effective for those people whose bodies are capable of producing insulin naturally. It is never used to treat type 1 diabetes since the body that suffers from this condition isn’t capable of producing insulin on its own. It is also not used to treat diabetic ketoacidosis, which is a condition that occurs when blood sugar levels aren’t monitored and treated.
There are also other reasons why the drug should be taken. Your doctor should explain what the drug is used for and why you need to use the drug in your case.
Glyburide dosage is different for different patients. You should follow the doctor’s recommendations or the instructions on the label to make sure that your dose is effective. If your doctor gives you different directions, follow them.
Oral administration is recommended for patients who are prescribed to take the medicine. It can be taken with breakfast or just the first meal.
