Glipizide and metformin (Oral route)
GLIP-i-zide, met-FOR-min hye-droe-KLOR-ide
Lactic acidosis is a rare, but serious, metabolic complication that can occur due to metformin accumulation during treatment with glipizide/metformin hydrochloride; when it occurs, it is fatal in approximately 50% of cases. The risk of lactic acidosis increases with renal impairment, increased age, diabetes mellitus, congestive heart failure, hepatic insufficiency, and other conditions whenever there is significant tissue hypoperfusion and hypoxemia. Treatment with glipizide/metformin hydrochloride should not be initiated in patients 80 years of age or older unless measurement of creatinine clearance demonstrates that renal function is normal. Therapy should temporarily be discontinued prior to any intravascular radiocontrast study or surgical procedure. Avoid excessive alcohol use since alcohol potentiates the effects of metformin on lactate metabolism. Discontinue therapy immediately and institute supportive measures promptly for suspected lactic acidosis .
2nd Generation Sulfonylurea
Uses of This Medicine:
Glipizide and Metformin combination is used to treat high blood sugar levels that are caused by a type of diabetes mellitus or sugar diabetes called type 2 diabetes. Normally, after you eat, your pancreas releases insulin to help your body store excess sugar for later use. This process occurs during normal digestion of food. In type 2 diabetes, your body does not work properly to store the excess sugar and the sugar remains in your bloodstream. Chronic high blood sugar can lead to serious health problems in the future. Proper diet is the first step in managing type 2 diabetes but often medicines are needed to help your body. With two actions, the combination of glipizide and metformin helps your body cope with high blood sugar. Glipizide stimulates the release of insulin from the pancreas, directing your body to store blood sugar. Metformin has three different actions: it slows the absorption of sugar in your small intestine; it also stops your liver from converting stored sugar into blood sugar; and it helps your body use your natural insulin more efficiently.
This medicine is available only with your doctor's prescription.

Precautions While Using This Medicine:
Your doctor will want to check your progress at regular visits , especially during the first few weeks that you take this medicine.
Under certain conditions, too much glipizide and metformin can cause lactic acidosis. Symptoms of lactic acidosis are severe and quick to appear and usually occur when other health problems not related to the medicine are present and are very severe, such as a heart attack or kidney failure. Symptoms of lactic acidosis include abdominal or stomach discomfort; decreased appetite; diarrhea; fast, shallow breathing; general feeling of discomfort; muscle pain or cramping; and unusual sleepiness, tiredness, or weakness.
If symptoms of lactic acidosis occur, you should get immediate emergency medical help.
It is very important to follow carefully any instructions from your health care team about:
In case of emergency—There may be a time when you need emergency help for a problem caused by your diabetes. You need to be prepared for these emergencies. It is a good idea to wear a medical identification (ID) bracelet or neck chain at all times. Also, carry an ID card in your wallet or purse that says that you have diabetes and a list of all your medicines.
Symptoms of hypoglycemia (low blood sugar) include anxiety; behavior change similar to being drunk; blurred vision; cold sweats; confusion; cool, pale skin; difficulty in thinking; drowsiness; excessive hunger; fast heartbeat; headache (continuing); nausea; nervousness; nightmares; restless sleep; shakiness; slurred speech; or unusual tiredness or weakness.
Glipizide and metformin combination can cause low blood sugar. However, it also can occur if you delay or miss a meal or snack, drink alcohol, exercise more than usual, cannot eat because of nausea or vomiting, take certain medicines, or take glipizide and metformin with another type of diabetes medicine. Symptoms of low blood sugar must be treated before they lead to unconsciousness (passing out). Different people feel different symptoms of low blood sugar. It is important that you learn which symptoms of low blood sugar you usually have so that you can treat it quickly.
If symptoms of low blood sugar occur, eat glucose tablets or gel, corn syrup, honey, or sugar cubes; or drink fruit juice, nondiet soft drink, or sugar dissolved in water. Also, check your blood for low blood sugar. Glucagon is used in emergency situations when severe symptoms such as seizures (convulsions) or unconsciousness occur. Have a glucagon kit available, along with a syringe or needle, and know how to use it. Members of your household also should know how to use it.
Symptoms of hyperglycemia (high blood sugar) include blurred vision; drowsiness; dry mouth; flushed, dry skin; fruit-like breath odor; increased urination (frequency and volume); ketones in urine; loss of appetite; sleepiness; stomachache, nausea, or vomiting; tiredness; troubled breathing (rapid and deep); unconsciousness; or unusual thirst.
High blood sugar may occur if you do not exercise as much as usual, have a fever or infection, do not take enough or skip a dose of your diabetes medicine, or overeat or do not follow your meal plan.
If symptoms of high blood sugar occur, check your blood sugar level and then call your health care professional for instructions.
