ADVERSE REACTIONS

displayName: ADVERSE REACTIONS SECTION
FDA Article Code: 34084-4

In a U.S. double-blind clinical study of metformin hydrochloride tablets in patients with type 2 diabetes, a total of 141 patients received metformin hydrochloride tablet therapy (up to 2550 mg per day) and 145 patients received placebo. Adverse reactions reported in greater than 5% of the metformin hydrochloride tablet patients, and that were more common in metformin hydrochloride tablet- than placebo-treated patients, are listed in Table 9.

Diarrhea led to discontinuation of study medication in 6% of patients treated with metformin hydrochloride tablets. Additionally, the following adverse reactions were reported in ≥ 1.0 to ≤ 5.0% of metformin hydrochloride tablet patients and were more commonly reported with metformin hydrochloride tablets than placebo: abnormal stools, hypoglycemia, myalgia, lightheaded, dyspnea, nail disorder, rash, sweating increased, taste disorder, chest discomfort, chills, flu syndrome, flushing, palpitation.

OVERDOSAGE


id: 029ae4f3-5d77-408c-a544-90cd3e6af64b
displayName: OVERDOSAGE SECTION
FDA Article Code: 34088-5

Overdose of metformin hydrochloride has occurred, including ingestion of amounts greater than 50 grams. Hypoglycemia was reported in approximately 10% of cases, but no causal association with metformin hydrochloride has been established. Lactic acidosis has been reported in approximately 32% of metformin overdose cases (see WARNINGS). Metformin is dialyzable with a clearance of up to 170 mL/min under good hemodynamic conditions. Therefore, hemodialysis may be useful for removal of accumulated drug from patients in whom metformin overdosage is suspected.

DOSAGE AND ADMINISTRATION


id: d15daa0a-61f7-47cb-9d69-9efd4c491cc4
displayName: DOSAGE & ADMINISTRATION SECTION
FDA Article Code: 34068-7

There is no fixed dosage regimen for the management of hyperglycemia in patients with type 2 diabetes with metformin hydrochloride tablets USP or any other pharmacologic agent. Dosage of metformin hydrochloride tablets USP must be individualized on the basis of both effectiveness and tolerance, while not exceeding the maximum recommended daily doses. The maximum recommended daily dose of metformin hydrochloride tablets USP is 2550 mg in adults and 2000 mg in pediatric patients (10 to 16 years of age). Metformin hydrochloride tablets USP should be given in divided doses with meals. Metformin hydrochloride tablets USP should be started at a low dose, with gradual dose escalation, both to reduce gastrointestinal side effects and to permit identification of the minimum dose required for adequate glycemic control of the patient. During treatment initiation and dose titration (see Recommended Dosing Schedule), fasting plasma glucose should be used to determine the therapeutic response to metformin hydrochloride tablets USP and identify the minimum effective dose for the patient. Thereafter, glycosylated hemoglobin should be measured at intervals of approximately three months. The therapeutic goal should be to decrease both fasting plasma glucose and glycosylated hemoglobin levels to normal or near normal by using the lowest effective dose of metformin hydrochloride tablets USP, either when used as monotherapy or in combination with sulfonylurea or insulin. Monitoring of blood glucose and glycosylated hemoglobin will also permit detection of primary failure, i.e., inadequate lowering of blood glucose at the maximum recommended dose of medication, and secondary failure, i.e., loss of an adequate blood glucose lowering response after an initial period of effectiveness. Short-term administration of metformin hydrochloride tablets USP may be sufficient during periods of transient loss of control in patients usually well-controlled on diet alone.

Rx only Read this information carefully before you start taking this medicine and each time you refill your prescription. There may be new information. This information does not take the place of your doctor’s advice. Ask your doctor or pharmacist if you do not understand some of this information or if you want to know more about this medicine. What are metformin hydrochloride tablets USP? Metformin hydrochloride tablets USP are used to treat type 2 diabetes. This is also known as non-insulin-dependent diabetes mellitus. People with type 2 diabetes are not able to make enough insulin or respond normally to the insulin their bodies make. When this happens, sugar (glucose) builds up in the blood. This can lead to serious medical problems including kidney damage, amputations, and blindness. Diabetes is also closely linked to heart disease. The main goal of treating diabetes is to lower your blood sugar to a normal level. High blood sugar can be lowered by diet and exercise, by a number of medicines taken by mouth, and by insulin shots. Before you take metformin hydrochloride tablets USP, try to control your diabetes by exercise and weight loss. While you take your diabetes medicine, continue to exercise and follow the diet advised for your diabetes. No matter what your recommended diabetes management plan is, studies have shown that maintaining good blood sugar control can prevent or delay complications of diabetes, such as blindness. Metformin hydrochloride tablets USP help control your blood sugar in a number of ways. These include helping your body respond better to the insulin it makes naturally, decreasing the amount of sugar your liver makes, and decreasing the amount of sugar your intestines absorb. Metformin hydrochloride tablets USP do not cause your body to make more insulin. Because of this, when taken alone, they rarely cause hypoglycemia (low blood sugar), and usually do not cause weight gain. However, when they are taken with a sulfonylurea or with insulin, hypoglycemia is more likely to occur, as is weight gain. WARNING: A small number of people who have taken metformin hydrochloride tablets USP have developed a serious condition called lactic acidosis. Lactic acidosis is caused by a buildup of lactic acid in the blood. This happens more often in people with kidney problems. Most people with kidney problems should not take metformin hydrochloride tablets USP. (See “What are the side effects of metformin hydrochloride tablets USP?”). Who should not take metformin hydrochloride tablets USP? Some conditions increase your chance of getting lactic acidosis, or cause other problems if you take metformin. Most of the conditions listed below can increase your chance of getting lactic acidosis. Do not take metformin hydrochloride tablets USP if you: have kidney problems

Metformin hydrochloride tablets USP have not been studied in children younger than 10 years old.

What are the side effects of metformin hydrochloride tablets USP?
Lactic Acidosis

. In rare cases, metformin hydrochloride tablets USP can cause a serious side effect called lactic acidosis. This is caused by a buildup of lactic acid in your blood. This buildup can cause serious damage. Lactic acidosis caused by metformin hydrochloride tablets USP is rare and has occurred mostly in people whose kidneys were not working normally. Lactic acidosis has been reported in about one in 33,000 patients taking metformin hydrochloride tablets USP over the course of a year. Although rare, if lactic acidosis does occur, it can be fatal in up to half the people who develop it.
It is also important for your liver to be working normally when you take metformin hydrochloride tablets USP. Your liver helps remove lactic acid from your body. Make sure you tell your doctor before you use metformin hydrochloride tablets USP if you have kidney or liver problems. You should also stop using metformin hydrochloride tablets USP and call your doctor right away if you have signs of lactic acidosis. Lactic acidosis is a medical emergency that must be treated in a hospital. Signs of lactic acidosis are: feeling very weak, tired, or uncomfortable
unusual muscle pain
trouble breathing
unusual or unexpected stomach discomfort
feeling cold
feeling dizzy or lightheaded
suddenly developing a slow or irregular heartbeat
If your medical condition suddenly changes, stop taking metformin hydrochloride tablets USP and call your doctor right away. This may be a sign of lactic acidosis or another serious side effect.

Tell your doctor if the side effects bother you a lot, last for more than a few weeks, come back after they’ve gone away, or start later in therapy.

Metformin hydrochloride tablets USP rarely cause hypoglycemia (low blood sugar) by themselves. However, hypoglycemia can happen if you do not eat enough, if you drink alcohol, or if you take other medicines to lower blood sugar.
