Istavel 100mg Tablet is a medication specifically used for the treatment of type 2 diabetes mellitus. It contains Sitagliptin 100mg, which helps manage blood sugar levels when combined with a healthy diet and regular exercise. This helps reduce the risk of serious diabetes complications like kidney damage and vision problems. Typically, Istavel 100mg Tablet is prescribed when diet and exercise alone or other medications haven't sufficiently controlled blood sugar. Your doctor may prescribe it by itself or alongside other diabetes medicines. It can be taken with or without food, and the dosage will be determined by your doctor based on your condition and blood sugar levels. Always follow your doctor's instructions. For best results, take Istavel 100mg Tablet at the same time each day. Do not stop taking this medicine without your doctor's recommendation, as it is crucial for controlling your blood sugar and preventing future complications. Maintaining a healthy lifestyle, including diet and exercise, is vital while on this medication, as it significantly impacts diabetes management. The most common side effect is a headache, which is usually mild and temporary. If you are also taking other diabetes medicines like insulin or sulfonylurea, there's a possibility of low blood sugar (hypoglycemia). It's important to learn how to recognize and manage hypoglycemia symptoms. Other possible side effects include upper respiratory tract infections such as sore throat, cough, and cold. If side effects are persistent or concerning, consult your doctor. Before starting Istavel 100mg Tablet, inform your doctor about any history of kidney disease, heart or pancreas problems, or if you consume alcohol regularly.
