Allergies can make us feel uncomfortable. Many people use medications to help. One common allergy medicine is Allegra. It is important to know how it affects our bodies. A big question is: Does Allegra raise blood sugar?
What is Allegra?
Allegra is the brand name for fexofenadine. It is an antihistamine. Antihistamines help with allergy symptoms. They block histamines in our body. Histamines can cause sneezing, runny nose, and itchy eyes.

Does Allegra Affect Blood Sugar Levels?
The short answer is no. Allegra does not usually raise blood sugar levels. Studies show that fexofenadine does not affect glucose metabolism. This means it does not change how our body uses sugar.
What Are the Risks of Other Allergy Medicines?
While Allegra is safe, other allergy medicines can raise blood sugar. Let’s look at some of them:
- Corticosteroids: These can raise blood sugar. They make the liver produce more glucose.
- Decongestants: Some contain pseudoephedrine. This can increase blood sugar levels.
- Older Antihistamines: Some can cause drowsiness. This might make blood sugar monitoring harder.
Who Should Be Careful?
People with diabetes should be careful. They need to monitor their blood sugar. If you have diabetes, discuss your allergy medications with your doctor. This is very important.
Can Diabetics Take Allegra-D?
Allegra-D is a different type of Allegra. It contains pseudoephedrine. This is a decongestant. People with diabetes should be careful with Allegra-D.
Before taking Allegra-D, talk to your doctor. They can tell you how it may affect your blood sugar. They might suggest you check your blood sugar more often.
