Answers to Common Questions
You already know that adding insulin to your treatment plan is a life-changing event
and there are many things to think about. Even after you've researched it, talked
about it, tried different lifestyle changes, you may still have some questions.
That's normal–so we've provided some answers that may help.
What is A1C?
A1C measures your average blood sugar levels over the past 2 to 3 months. It provides an accurate view of your success managing blood sugar over a longer period of time. The ADA recommends an A1C of less than 7% for most people with diabetes. Ask your doctor about blood sugar goals that are right for you, and if your A1C is too high, ask about ways you can get it on track.
How often should A1C be checked?
It should be done 2 to 4 times each year depending on how well your blood sugar levels are under control.
Can I use Lantus® along with short- or rapid-acting insulins?
Yes. Lantus® can be used with mealtime insulins. Lantus® helps control blood sugar levels between meals and overnight. Mealtime insulin (short- or rapid-acting insulin) is taken with meals to control blood sugar spikes caused by food. So your doctor may prescribe a mealtime insulin to work with Lantus®.
How much can I exercise while taking Lantus®?
When you exercise, your muscles use up sugar. The harder you work out, the more your blood sugar levels fluctuate. That’s why before starting any exercise program, talk to your doctor first. Generally, people with diabetes should always exercise in moderation, and make sure they have food and water with them.
Will I always be on the same dose of Lantus®?
Probably not. At first, your healthcare professional may adjust your dose of Lantus® to find what works for you. You may start with a low dose to see how well Lantus® helps control your blood sugar. Your healthcare professional may then change the amount. This change is a normal part of the process of improving your blood sugar levels. If, after you start taking Lantus®, your blood sugar level stays too high, and your healthcare professional doesn’t change your dose, ask why.
What should I do if I become pregnant?
Contact your doctor immediately.
Does taking more insulin mean I am getting worse?
Type 2 diabetes can get harder to handle over time, which happens when the body isn’t producing enough insulin, or not using insulin properly. The type of medicine you take, the dose you take, and the length of time using the medicines don’t necessarily indicate the severity of your disease.
