Which medicines need extra care

Insulin and medicines called sulfonylureas can cause low blood glucose. Skipping a meal, sharply reducing carbohydrate, drinking alcohol or adding unexpected activity may change your risk. Other medicines have different effects, so know your own care plan.

Recognize possible low glucose

Shaking, sweating, hunger, dizziness, confusion or unusual weakness can occur with low glucose. If you use a meter or CGM, follow the treatment plan your clinician gave you. Severe confusion, seizure or unconsciousness is an emergency.

Change food safely

Meal balance, fiber and activity can still help, but Syndova does not adjust medicine doses. Discuss major carbohydrate, fasting or exercise changes with the clinician who manages your diabetes medicine.

Key takeaways

Insulin and sulfonylureas can cause low glucose.
Use your prescribed low-glucose plan, not a meal-photo estimate.
Review major food or activity changes with your clinician.
