What is alogliptin and metformin?
Alogliptin and metformin are oral diabetes medicines that help control blood sugar levels.
Metformin works by decreasing glucose (sugar) production in the liver and decreasing absorption of glucose by the intestines. Alogliptin works by regulating the levels of insulin your body produces after eating.
Alogliptin and metformin is a combination medicine that is used together with diet and exercise to improve blood sugar control in adults with type 2 diabetes mellitus. This medicine is not for treating type 1 diabetes.
Alogliptin and metformin may also be used for purposes not listed in this medication guide.
You should not use this medicine if you have severe kidney disease or diabetic ketoacidosis (call your doctor for treatment).
You may develop lactic acidosis, a dangerous build-up of lactic acid in your blood. Call your doctor or get emergency medical help if you have unusual muscle pain, trouble breathing, stomach pain, dizziness, feeling cold, or feeling very weak or tired.

You may develop lactic acidosis, a dangerous build-up of lactic acid in your blood. This may be more likely if you have other medical conditions, a severe infection, chronic alcoholism, or if you are 65 or older. Ask your doctor about your risk.
If you need to have any type of x-ray or CT scan using a dye that is injected into your veins, you will need to temporarily stop taking alogliptin and metformin. Be sure your caregivers know ahead of time that you are using this medicine.

How should I take alogliptin and metformin?
Follow all directions on your prescription label and read all medication guides or instruction sheets. Use the medicine exactly as directed.
Take alogliptin and metformin with meals.
Low blood sugar (hypoglycemia) can happen to everyone who has diabetes. Symptoms include headache, hunger, sweating, irritability, dizziness, nausea, fast heart rate, and feeling anxious or 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.
Also watch for signs of high blood sugar (hyperglycemia) such as increased thirst or urination, blurred vision, headache, and tiredness.
Alogliptin and metformin 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.
Your doctor may have you take extra vitamin B12 while you are taking alogliptin and metformin. Take only the amount of vitamin B12 that your doctor has prescribed.
Store at room temperature away from moisture and heat.
What happens if I miss a dose?
Take the medicine (with food) as soon as you can, but skip the missed dose if it is almost time for your next dose. Do not take 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. You may have severely low blood sugar (extreme weakness, nausea, tremors, sweating, confusion, trouble speaking, fast heartbeats, or seizure).
What should I avoid while taking alogliptin and metformin?
Avoid drinking alcohol. It lowers blood sugar and may increase your risk of lactic acidosis.
