Should I take my glucose tests before or after I take my morning and evening oral medications?
It depends on what type of medication you are taking and what information you would like to get from the numbers. Some medications work on blood glucose all day long and overnight too. For these medications, it’s best to check your blood glucose first thing in the morning or before your meals. Other medications are taken to lower blood glucose after the meal. For these medications, it’s best to check your blood glucose 2 hours after your have eaten. Occasionally, it’s helpful to check the blood glucose both before and 2 hours after the meal. This will tell you how well your medication is working and give you important information about how carbohydrate foods you have eaten are affecting your blood glucose levels. Ask your healthcare provider if your medications work to lower the fasting blood glucose or the after-meal blood glucose. Once you know this information, you will have a better idea of when to check your blood glucose.
