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.

My health care provider told me the most important times to check your blood sugar are first thing in the morning and just before bed. I check mine at least 3 times a day and it is usually just before meals. If I check any more than that, it is because I am not feeling right.

Your response to Poppie said some BG medicines work all day and all night too; while others work to lower BG after a meal. I take Metformic. In which catagory does it fall?

That is a very good question Mike, and thanks Patty for your answer. I always check my b/s levels before I eat, and before taking any meds. That is a good question for those ones who are uneducated about being a diabetic.
