Warnings
Black Box Warnings
Congestive heart failure risk
Thiazolidinediones, including rosiglitazone, cause or exacerbate congestive heart failure in some patients
After initiation, and after dose increases, observe patients carefully for signs and symptoms of heart failure (including excessive, rapid weight gain, dyspnea, and/or edema)
If these signs and symptoms develop, the heart failure should be managed according to current standards of care
Furthermore, discontinuation or dose reduction must be considered
Not recommended in patients with symptomatic heart failure
Initiation with established NYHA Class III or IV heart failure is contraindicated
Contraindications
Hypersensitivity to rosiglitazone
Heart failure NYHA class III-IV
Cautions
Fluid retention, which may exacerbate or lead to heart failure, may occur; this drug like other thiazolidinediones, alone or in combination with other antidiabetic agents, can cause fluid retention, which may exacerbate or lead to heart failure; patients should be observed for signs and symptoms of heart failure; combination use with insulin and use in congestive heart failure NYHA Class I and II may increase risk of other cardiovascular effects
If ALT >3 x ULN stop treatment; if 1.5-3 x normal, retest qWeek until normal or 3 x normal and need to discontinue
Not for use in diabetes mellitus type 1; mechanism requires presence of endogenous insulin; use with insulin may increase risk of heart failure; not recommended
Coadministration of this medication and insulin is not recommended
Thiazolidinediones, which are peroxisome proliferator-activated receptor (PPAR) gamma agonists, can cause dose-related fluid retention, particularly when used in combination with insulin; dose-related edema and weight gain may occur; since thiazolidinediones, including rosiglitazone, can cause fluid retention, which can exacerbate or lead to congestive heart failure, this drug should be used with caution in patients at risk for heart failure; patients should be monitored for signs and symptoms of heart failure; patients with ongoing edema are more likely to have adverse events associated with edema if started on combination therapy with insulin and this drug
Dose-related weight gain seen with this drug alone and in combination with other hypoglycemic agents; mechanism of weight gain is unclear but probably involves combination of fluid retention and fat accumulation; patients who experience increases in weight gain should be assessed for fluid accumulation and volume-related events such as excessive edema and congestive heart
When used in combination with other hypoglycemic agents, a dose reduction of concomitant agent may be necessary to reduce risk of hypoglycemia
Associated with rare cases of new onset or worsening of macular edema
May result in ovulation in some premenopausal anovulatory women; ensure adequate contraception
Increased risk of fractures of upper arm, hand, or foot in female patients
Dose-related decreases in hemoglobin and hematocrit reported; observed changes may be related to increased plasma volume observed with treatment
Hepatic effects
- Liver enzymes should be measured prior to initiation of therapy with this medication in all patients and periodically thereafter per the clinical judgment of healthcare professional; therapy with this medication should not be initiated in patients with increased baseline liver enzyme levels (ALT >2.5X upper limit of normal)
- Patients with mildly elevated liver enzymes (ALT levels ≤2.5X upper limit of normal) at baseline or during therapy with AVANDIA should be evaluated to determine cause of liver enzyme elevation; initiation of, or continuation of, therapy with this medication in patients with mild liver enzyme elevations should proceed with caution and include close clinical follow-up, including liver enzyme monitoring, to determine ifliver enzyme elevations resolve or worsen
- If at any time ALT levels increase to >3X the upper limit of normal in patients on therapy with this medication, liver enzyme levels should be rechecked as soon as possible; if ALT levels remain >3X upper limit of normal, therapy should be discontinued
- If any patient develops symptoms suggesting hepatic dysfunction, which may include unexplained nausea, vomiting, abdominal pain, fatigue, anorexia, and/or dark urine, liver enzymes should be checked; the decision whether to continue patient on therapy with this medication should be guided by clinical judgment pending laboratory evaluations; if jaundice is observed, drug therapy should be discontinued
Macular edema
- Macular edema has been reported in postmarketing experience in diabetic patients taking this medication or another thiazolidinedione; some patients have presented with blurred vision or decreased visual acuity, but some patients appear to have been diagnosed on routine ophthalmologic examination
- Patients may experience peripheral edema at time macular edema diagnosed; some patients may show improvement in macular edema after discontinuation of thiazolidinedione
- Patients with diabetes should have regular eye exams by an ophthalmologist, per the Standards of Care of the American Diabetes Association; additionally, any diabetic who reports any kind of visual symptom should be promptly referred to an ophthalmologist, regardless of patient’s underlying medications or other physical findings
Fractures
- Long-term trials show an increased incidence of bone fracture inpatients, particularly female patients, taking this medication; this increased incidence was noted after first year of treatment and persisted during course of the trial
- The majority of fractures in women who received this medicaiton occurred in upper arm, hand, and foot; these sites of fracture are different from those usually associated with postmenopausal osteoporosis (eg, hip or spine)
- Other trials suggest that this risk may also apply to men, although risk of fracture among women appears higher than that among men; the risk of fracture should be considered in care of patients treated with this medication, and attention given to assessing and maintaining bone health according to current standards of care
Pregnancy & Lactation
Pregnancy
Limited data in pregnant women are not sufficient to determine drug- associated risk for major birth defects or miscarriage; there are risks to mother and fetus associated with poorly controlled diabetes in pregnancy
Poorly controlled diabetes in pregnancy increases maternal risk for diabetic ketoacidosis, pre-eclampsia, spontaneous abortions, preterm delivery, and delivery complications; poorly controlled diabetes increases fetal risk for major birth defects, stillbirth, and macrosomia-related morbidity
Animal data
- In animal reproduction studies, no adverse developmental effects observed when drug was administered to pregnant rats and rabbits during organogenesis at exposures up to 4 times the maximum recommended human dose (MRHD) of 8 mg daily
Reproductive potential of patients
- Discuss potential for unintended pregnancy with premenopausal women as therapy may result in ovulation in some anovulatory women
Lactation
There are no data on presence of rosiglitazone in human milk, effects on breastfed infant, or on milk production; drug is present in rat milk; however, due to species-specific differences in lactation physiology, animal data may not reliably predict drug levels in human milk; developmental and health benefits of breastfeeding should be considered along with mother's clinical need for therapy and any potential adverse effects on breastfed infant or the underlying maternal condition
Pregnancy Categories
A: Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.
B: May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk. C: Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done. D: Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk. X: Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist. NA: Information not available.Pharmacology
Mechanism of Action
Lowers glucose by improving target cell response to insulin without increasing pancreatic cell secretion; activates nuclear peroxisome proliferator-activated receptor gamma, which influences the production of gene products involved in glucose and lipid metabolism
Pharmacokinetics

Onset of Action: Initial effect delayed; maximum effect may take up to 12 weeks
Peak Plasma Time: 1 hr
Protein Bound: >99%
Half-Life: 3-4 hr
Vd: 17.6 L
Metabolism: by hepatic CYP2C8 & CYP2C9 (minor extent)
Excretion: urine 64%; feces 22%
