What should I discuss with my doctor before taking tolbutamide (Orinase)?
Do not use this medication if you are allergic to tolbutamide, or if you are in a state of diabetic ketoacidosis. Call your doctor for treatment with insulin.
To make sure you can safely take tolbutamide, tell your doctor if you have any of these other conditions:
Certain oral diabetes medications may increase your risk of serious heart problems. However, not treating your diabetes can damage your heart and other organs. Talk to your doctor about the risks and benefits of treating your diabetes with tolbutamide.
FDA pregnancy category C. It is not known whether tolbutamide will harm an unborn baby. Similar diabetes medications have caused severe hypoglycemia in newborn babies whose mothers had used the medication near the time of delivery. Tell your doctor if you are pregnant or plan to become pregnant while using this medication.
It is not known whether tolbutamide passes into breast milk or if it could be harmful to a nursing baby. You should not breast-feed while you are taking tolbutamide.
How should I take tolbutamide (Orinase)?
Take exactly as prescribed by your doctor. Do not take in larger or smaller amounts or for longer than recommended. Follow the directions on your prescription label.
Follow your doctor's instructions about how often to take tolbutamide, and whether or not you should take it with food.
Your blood sugar will need to be checked often, and you may need other blood tests at your doctor's office. Visit your doctor regularly.
Know the signs of low blood sugar (hypoglycemia) and how to recognize them: headache, hunger, weakness, sweating, tremor, irritability, or trouble concentrating.
Always keep a source of sugar available in case you have symptoms of low blood sugar. Sugar sources include orange juice, glucose gel, candy, or milk. If you have severe hypoglycemia and cannot eat or drink, use an injection of glucagon. Your doctor can give you a prescription for a glucagon emergency injection kit and tell you how to give the injection.
Also watch for signs of blood sugar that is too high (hyperglycemia). These symptoms include increased thirst, increased urination, hunger, dry mouth, fruity breath odor, drowsiness, dry skin, blurred vision, and weight loss.
Check your blood sugar carefully during a time of stress or illness, if you travel, exercise more than usual, drink alcohol, or skip meals. These things can affect your glucose levels and your dose needs may also change.
Your doctor may want you to stop taking tolbutamide for a short time if you become ill, have a fever or infection, or if you have surgery or a medical emergency.
Ask your doctor how to adjust your tolbutamide dose if needed. Do not change your medication dose or schedule without your doctor's advice.
Tolbutamide is only part of a complete program of treatment that may also include diet, exercise, weight control, and testing your blood sugar. Follow your diet, medication, and exercise routines very closely. Changing any of these factors can affect your blood sugar levels.
Use tolbutamide regularly to get the most benefit. Get your prescription refilled before you run out of medicine completely.
Store at room temperature away from moisture, heat, and light.
