What is tolazamide?
Tolazamide causes the pancreas to produce insulin and increases your body's response to it.
Tolazamide may also be used for purposes not listed in this medication guide.
Follow all directions on your medicine label and package. Tell each of your healthcare providers about all your medical conditions, allergies, and all medicines you use.
Before taking this medicine
You should not use tolazamide if you are allergic to tolazamide, or if have diabetic ketoacidosis (call your doctor for treatment).
Tell your doctor if you have ever had:
liver or kidney disease;
an adrenal or pituitary gland disorder; or
a genetic enzyme deficiency called glucose-6-phosphate dehydrogenase (G6PD) deficiency.
Before taking tolazamide, tell your doctor if you have taken another oral diabetes medicine or used insulin during the past 2 weeks.
Tolazamide may increase your risk of serious heart problems, but not treating your diabetes can also damage your heart and other organs. Talk to your doctor about the risks and benefits of this medicine.
Follow your doctor's instructions about using this medicine if you are pregnant or breast-feeding a baby. Blood sugar control is very important during pregnancy, and your dose needs may be different during each trimester of pregnancy.
Taking tolazamide during the last 2 weeks of pregnancy may cause severe hypoglycemia in the newborn baby. Ask your doctor for a safer medicine to use during late pregnancy.
You should not breast-feed while using this medicine.
How should I take tolazamide?
Tolazamide is usually taken with breakfast or the first main meal of the day.
Follow all directions on your prescription label and read all medication guides or instruction sheets. Use the medicine exactly as directed.
Your blood sugar will need to be checked often, and you may need other blood tests at your doctor's office.
Low blood sugar (hypoglycemia) can happen to everyone who has diabetes. Symptoms include headache, hunger, sweating, irritability, dizziness, nausea, and feeling shaky. To quickly treat low blood sugar, always keep a fast-acting source of sugar with you such as fruit juice, hard candy, crackers, raisins, or non-diet soda.
Your doctor can prescribe a glucagon emergency injection kit to use in case you have severe hypoglycemia and cannot eat or drink. Be sure your family and close friends know how to give you this injection in an emergency.
Blood sugar levels can be affected by stress, illness, surgery, exercise, alcohol use, or skipping meals. Ask your doctor before changing your dose or medication schedule.
Tolazamide is only part of a complete treatment program that may also include diet, exercise, weight control, regular blood sugar testing, and special medical care. Follow your doctor's instructions very closely.
Store at room temperature away from moisture, heat, and light.
What happens if I miss a dose?
Take your dose (with food) as soon as you can, but skip the missed dose if it is almost time for your next dose. Do not use two doses at one time.
What happens if I overdose?
Seek emergency medical attention or call the Poison Help line at 1-800-222-1222. A tolazamide overdose can cause life-threatening hypoglycemia.
Symptoms of severe hypoglycemia include extreme weakness, nausea, tremors, sweating, confusion, trouble speaking, fast heartbeats, or seizure.
What should I avoid while taking tolazamide?
Avoid drinking alcohol. It lowers blood sugar and may interfere with your diabetes treatment.
Tolazamide could make you sunburn more easily. Avoid sunlight or tanning beds. Wear protective clothing and use sunscreen (SPF 30 or higher) when you are outdoors.
