This medication may rarely cause serious changes in blood sugar, especially if you have diabetes. Check your blood sugar regularly as directed and share the results with your doctor. Watch for symptoms of high blood sugar, such as increased thirst/urination. Also watch for symptoms of low blood sugar such as sudden sweating, shaking, fast heartbeat, hunger, blurred vision, dizziness, or tingling hands/feet.

Your doctor may need to switch you to another antibiotic or adjust your diabetes medications if any reaction occurs.
