What is Janumet?
You should not use Janumet if you have liver or kidney disease, or if you are in a state of diabetic ketoacidosis (call your doctor for treatment with insulin). Janumet may cause a serious condition called lactic acidosis.Get emergency medical help if you have even mild symptoms such as: muscle pain or weakness, numb or cold feeling in your arms and legs, trouble breathing, stomach pain, nausea with vomiting, fast or uneven heart rate, dizziness, or feeling very weak or tired.
Before taking this medicine
You should not use Janumet if you are allergic to metformin (Actoplus Met, Avandamet, Fortamet, Glucophage, Riomet) or sitagliptin (Januvia), if you have kidney disease, or if you are in a state of diabetic ketoacidosis (call your doctor for treatment with insulin). Some people taking metformin develop a serious condition called lactic acidosis. This may be more likely if you have liver or kidney disease, congestive heart failure, a severe infection, if you are dehydrated, or if you drink large amounts of alcohol. Talk with your doctor about your risk. To make sure Janumet is safe for you, tell your doctor if you have:
liver disease; a history of heart disease; pancreatitis; high triglycerides (a type of fat in the blood); gallstones; a history of alcoholism; or if you are over 80 years old and have not recently had your kidney function checked. 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 Janumet. Be sure your caregivers know ahead of time that you are using this medication.
Janumet is not expected to harm an unborn baby. Tell your doctor if you are pregnant or plan to become pregnant. It is not known whether metformin and sitagliptin passes into breast milk or if it could harm a nursing baby. Tell your doctor if you are breast-feeding a baby. Janumet is not approved for use by anyone younger than 18 years old.
How should I take Janumet?
Take Janumet exactly as prescribed by your doctor. Follow all directions on your prescription label. Do not take this medicine in larger or smaller amounts or for longer than recommended. Your blood sugar will need to be checked often, and you may need other blood tests at your doctor's office. Take Janumet with meals. Do not crush, chew, or break an extended-release tablet. Swallow it whole. Janumet tablets may not completely dissolve in the body. Part of the tablet may appear in your stool. This is a normal side effect of Janumet and will not make the medicine less effective. Call your doctor if you see a tablet in your stool several times.
Low blood sugar (hypoglycemia) can happen to everyone who has diabetes. Symptoms include headache, hunger, sweating, pale skin, irritability, dizziness, feeling shaky, or trouble concentrating. Always keep a source of sugar with you in case you have low blood sugar. Sugar sources include fruit juice, hard candy, crackers, raisins, and non-diet soda. Be sure your family and close friends know how to help you in an emergency. If you have severe hypoglycemia and cannot eat or drink, use a glucagon injection. Your doctor can prescribe a glucagon emergency injection kit and tell you how to use it. Check your blood sugar carefully during times of stress, travel, illness, surgery or medical emergency, vigorous exercise, or if you drink alcohol or skip meals. These things can affect your glucose levels and your dose needs may also change. Do not change your medication dose or schedule without your doctor's advice. Janumet is only part of a complete program of treatment that may also include diet, exercise, weight control, foot care, and eye care. Follow your diet, medication, and exercise routines very closely. Store Janumet at room temperature away from moisture and heat.

my doctor is happy now. The only side effect is large hard stool which plugs the bathroom plumbing up every time, so I need to carry a plunger with me when away from home. Have been on it for about 3 months now, 100mg daily, along with 1000mg Metformin twice daily, and 4mg Glipizide twice daily.
