Note: This document contains side effect information about rosiglitazone. Some of the dosage forms listed on this page may not apply to the brand name Avandia.
Common side effects of Avandia include: headache. Other side effects include: edema and nausea. See below for a comprehensive list of adverse effects.
Applies to rosiglitazone: oral tablet
Oral route (Tablet)
Thiazolidinediones, including rosiglitazone, cause or exacerbate congestive heart failure in some patients. After initiation of rosiglitazone maleate, 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 of rosiglitazone maleate must be considered. Rosiglitazone maleate is not recommended in patients with symptomatic heart failure. Initiation of rosiglitazone maleate in patients with established NYHA Class III or IV heart failure is contraindicated.
Along with its needed effects, rosiglitazone (the active ingredient contained in Avandia) may cause some unwanted effects. Although not all of these side effects may occur, if they do occur they may need medical attention.
Check with your doctor immediately if any of the following side effects occur while taking rosiglitazone:
Incidence not known
Some side effects of rosiglitazone may occur that usually do not need medical attention. These side effects may go away during treatment as your body adjusts to the medicine. Also, your health care professional may be able to tell you about ways to prevent or reduce some of these side effects. Check with your health care professional if any of the following side effects continue or are bothersome or if you have any questions about them:
Applies to rosiglitazone: oral tablet
The most commonly reported adverse reports included upper respiratory tract infections, injury, and headache.
Major Adverse Cardiovascular Events:
Overall data from long-term rosiglitazone (the active ingredient contained in Avandia) trials including the RECORD, ADOPT, and DREAM trials (rosiglitazone n=6311; control n=7756) showed no difference in overall mortality or major adverse cardiovascular events; however, a meta-analysis of shorter-term trials suggests and increased risk for myocardial infarction with rosiglitazone compared with placebo.
The RECORD trial (Rosiglitazone evaluated for Cardiac Outcomes and Regulation of Glycemia in Diabetes) revealed no significant difference in cardiovascular hospitalization or cardiovascular death (primary outcome) among patients with type 2 diabetes receiving rosiglitazone add-on therapy (n=2220) compared with active control (n=2227); however, there was a significant difference in the incidence of CHF (secondary endpoint). Patients randomized were those who had failed metformin or sulfonylurea monotherapy; mean age: 58 years; 52% male. Following randomization to add-on rosiglitazone or active control (add-on metformin for those inadequately controlled on sulfonylurea or add-on sulfonylurea for those inadequately controlled on metformin) patients were treated to a target glycosylated hemoglobin (HbA1c) of 7% or less. Heart failure was reported in 61 patients receiving add-on rosiglitazone and 29 patients receiving active control.
In a retrospective analysis of 42 clinical trials (mean duration 6 months), rosiglitazone was associated with an increased risk of myocardial ischemia compared with combined active or placebo control (2% versus 1.53%). These events included angina pectoris, angina dyspnea, myocardial infarction, coronary thrombosis, myocardial ischemia, coronary artery disease, and coronary artery disorder. There was an increased risk with combination insulin therapy and in patients receiving nitrates for known coronary heart disease.
Cardiovascular Events in Patients with NYHA Class I and II Heart Failure:
An increased risk of cardiovascular events was observed in a 52-week trial in patients with NYHA Class I and II Heart Failure who were receiving rosiglitazone (n=110) compared with placebo (n=114). These events included: cardiovascular deaths (5% vs 4%), worsening CHF (6% vs 4%), new or worsening edema (25% vs 9%), new or worsening dyspnea (26% vs 17%), increases in CHF medication (33% vs 18%), and cardiovascular hospitalization (19% vs 13%).
-Dose-related edema was reported in rosiglitazone clinical trials. In patients receiving rosiglitazone 8 mg in combination with a sulfonylurea, the incidence of edema was 12.4%. In rosiglitazone monotherapy trials, edema was reported in 4.8% of patients (dose not specified). Healthy volunteers receiving rosiglitazone 8 mg once daily for 8 weeks experienced a statistically significant increase in median plasma volume compared with placebo.
Concomitant Administration with Insulin:
-Edema was reported with higher frequency in the rosiglitazone plus insulin combination trials (insulin, 5.4%; and rosiglitazone with insulin 14.7%). Reports of new onset or exacerbation of CHF occurred at a rate of 1% for insulin alone, 2% (4 mg) and 3% (8 mg) for insulin in combination with rosiglitazone. The coadministration of rosiglitazone and insulin is not recommended.
Common (1% to 10%): Edema, hypertension,
Frequency not reported: Cardiovascular deaths, congestive heart failure (CHF), myocardial infarction, angina, angina pectoris, angina dyspnea, myocardial infarction, coronary thrombosis, myocardial ischemia, coronary artery disease, coronary artery disorder
Anemia was reported in 1.9% of patients receiving rosiglitazone (the active ingredient contained in Avandia) as monotherapy. In combination therapy with metformin, a sulfonylurea, or metformin plus a sulfonylurea, the incidence of anemia was 7.1%, 2.3%, and 6.7%, respectively. Laboratory findings have shown dose-related decreases in hemoglobin and hematocrit; mean decreases in hemoglobin were 1 g/dL and up to 3.3% in hematocrit. These changes primarily occurred during the first 3 months or following a dose increase. They may be related to increased plasma volume.
Common (1% to 10%): Anemia
Frequency not reported: Decrease in WBC counts
Uncommon (0.1% to 1%): Hyperbilirubinemia, ALT elevations
Postmarketing reports: Hepatitis, hepatic enzyme elevations greater than 3 times the upper limit of normal, hepatic failure
Common (1% to 10%): Hyperglycemia, hypoglycemia, hypocholesterolemia
Uncommon (0.1% to 1%): Weight gain
Frequency not reported: Increases in waist and hip circumference
The mechanism of weight gain is unclear, although it probably is due to a combination of fluid retention and fat accumulation. In the ADOPT monotherapy trial, median weight change at 4 years was plus 3.5 kg.
Frequency not reported: Resumption of ovulation in premenopausal, anovulatory women, hormonal imbalance
Postmarketing reports: Anaphylactic reaction, urticaria, angioedema
Postmarketing reports: Rash, pruritus, urticaria, angioedema, Stevens-Johnson syndrome
Postmarketing reports: Diabetic macular edema with decreased visual acuity
Common (1% to 10%): Upper respiratory tract infection, sinusitis
Frequency not reported: Dyspnea
Postmarketing reports: Pulmonary edema, pleural effusions
Common (1% to 10%): Back pain
Frequency not reported: Fractures
Long-term clinical trials have shown an increased incidence of bone fracture in patients receiving drug compared with glyburide or metformin. This increased incidence appeared after the first year and persisted during the trials. The majority of fractures were observed in women and occurred in the upper arm, hand, and foot.
Common (1% to 10%): Diarrhea
Common (1% to 10%): Injury, fatigue
