Liver Dose Adjustments
Patients with mildly elevated serum transaminase levels at baseline (ALT 1 to 2.5 times the upper limit of normal) or during therapy, should be evaluated to determine the cause of the liver enzyme elevation. Initiation or continuation of therapy should proceed with caution and include close clinical monitoring in addition to frequent evaluation of liver enzymes. Rosiglitazone therapy should not be initiated in patients with increased serum transaminase levels (ALT greater than 2.5 times the upper limit of normal). If at any time liver enzymes increase to greater than 3 times the upper limit of normal, liver enzymes should be rechecked as soon as possible. If ALT levels remain greater than 3 times the upper limit of normal, rosiglitazone should be discontinued.
For patients receiving metformin, the current dose of metformin should be continued upon initiation of rosiglitazone therapy. If the patient does not show adequate response, the dosage of rosiglitazone may be increased to 8 mg per day (either once daily or in divided doses) after 12 weeks of therapy.
For patients receiving a sulfonylurea, the dosage recommendation above still applies. However, if patients report hypoglycemia, a decrease in the dose of the sulfonylurea is recommended.
All patients should start at the lowest recommended dose. Further increases in the dose should be accompanied by careful monitoring for adverse events related to fluid retention.
Safety and effectiveness have not been established in pediatric patients (less than 18 years of age).
