A fasting blood sugar of 240 mg/dL is elevated, but please do not panic; this is a highly manageable situation. Because choosing the right medication depends on your specific medical history, organ function, and whether you have Type 1 or Type 2 diabetes, you must consult a doctor for a prescription. Commonly prescribed generic medications to lower blood sugar include metformin, sulfonylureas (like glipizide), or SGLT2 inhibitors (like empagliflozin). For now, drink plenty of water to stay hydrated, avoid sugary or high-carbohydrate foods, and schedule an appointment with your healthcare provider promptly to safely get your levels back on track.
