2.1 Recommendations for All PatientsPioglitazone hydrochloride and metformin hydrochloride tablets should be taken with meals to reduce the gastrointestinal side effects associated with metformin.
If therapy with a combination tablet containing pioglitazone and metformin is considered appropriate the recommended starting dose is:
• 15 mg/500 mg twice daily or 15 mg/850 mg once daily and gradually titrated, as needed, after assessing adequacy of therapeutic response and tolerability, • for patients with New York Heart Association (NYHA) Class I or Class II congestive heart failure: 15 mg/500 mg or 15 mg/850 mg once daily and gradually titrated, as needed, after assessing adequacy of therapeutic response and tolerability, • for patients inadequately controlled on metformin monotherapy: 15 mg/500 mg twice daily or 15 mg/850 mg once or twice daily (depending on the dose of metformin already being taken) and gradually titrated, as needed, after assessing adequacy of therapeutic response and tolerability, • for patients inadequately controlled on pioglitazone monotherapy: 15 mg/500 mg twice daily or 15 mg/850 mg once daily and gradually titrated, as needed, after assessing adequacy of therapeutic response and tolerability, • for patients who are changing from combination therapy of pioglitazone plus metformin as separate tablets: Pioglitazone hydrochloride and metformin hydrochloride tablets should be taken at doses that are as close as possible to the dose of pioglitazone and metformin already being taken.Pioglitazone hydrochloride and metformin hydrochloride tablets may be titrated up to a maximum daily dose of 45 mg of pioglitazone and 2550 mg of metformin.
Metformin doses above 2000 mg may be better tolerated given 3 times a day.
After initiation of pioglitazone hydrochloride and metformin hydrochloride tablets or with dose increase, monitor patients carefully for adverse reactions related to fluid retention such as weight gain, edema, and signs and symptoms of congestive heart failure [see Boxed Warning and WARNINGS AND PRECAUTIONS (5.1)]. Liver tests (serum alanine and aspartate aminotransferases, alkaline phosphatase, and total bilirubin) should be obtained prior to initiating pioglitazone hydrochloride and metformin hydrochloride tablets. Routine periodic monitoring of liver tests during treatment with pioglitazone hydrochloride and metformin hydrochloride tablets are not recommended in patients without liver disease. Patients who have liver test abnormalities prior to initiation of pioglitazone hydrochloride and metformin hydrochloride tablets or who are found to have abnormal liver tests while taking pioglitazone hydrochloride and metformin hydrochloride tablets should be managed as described under Warnings and Precautions [see WARNINGS AND PRECAUTIONS (5.5) and CLINICAL PHARMACOLOGY (12.3)].
2.2 Concomitant Use with an Insulin Secretagogue or InsulinIf hypoglycemia occurs in a patient co-administered pioglitazone hydrochloride and metformin hydrochloride tablets and an insulin secretagogue (e.g., sulfonylurea), the dose of the insulin secretagogue should be reduced.
If hypoglycemia occurs in a patient co-administered pioglitazone hydrochloride and metformin hydrochloride tablets and insulin, the dose of insulin should be decreased by 10% to 25%. Further adjustments to the insulin dose should be individualized based on glycemic response.
2.3 Concomitant Use with Strong CYP2C8 InhibitorsCo-administration of pioglitazone (one of the ingredients in pioglitazone hydrochloride and metformin hydrochloride tablets) and gemfibrozil, a strong CYP2C8 inhibitor, increases pioglitazone exposure approximately 3-fold. Therefore, the maximum recommended dose of pioglitazone hydrochloride and metformin hydrochloride tablets are 15 mg/850 mg daily when used in combination with gemfibrozil or other strong CYP2C8 inhibitors [see DRUG INTERACTIONS (7.1) and CLINICAL PHARMACOLOGY (12.3)].
