What Are Warnings and Precautions for Rosiglitazone?


Effects of drug abuse

  • None

Short-Term Effects

  • See “What Are Side Effects Associated with Using Rosiglitazone?”

Long-Term Effects

  • See “What Are Side Effects Associated with Using Rosiglitazone?”


  • Fluid retention, which may exacerbate or lead to heart failure, may occur; combination use with insulin and use in congestive heart failure NYHA Class I and II may increase the risk of other cardiovascular effects
  • If ALT above 3 into ULN stop treatment; if 1.5-3 in to normal, retest every Week until normal or 3 in to normal and need to discontinue
  • Not for use in diabetes mellitus type 1; mechanism requires the presence of endogenous insulin; use with insulin may increase risk of heart failure; 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
  • When used in combination with other hypoglycemic agents, a dose reduction of the concomitant agent may be necessary to reduce the 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 the upper arm, hand, or foot in female patients
  • Dose-related decreases in hemoglobin and hematocrit reported

Pregnancy and Lactation

  • Limited data in pregnant women are not sufficient to determine a 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 the maternal risk for diabetic ketoacidosis, pre-eclampsia, spontaneous abortions, preterm delivery, and delivery complications; poorly controlled diabetes increases the fetal risk for major birth defects, stillbirth, and macrosomia-related morbidity
  • Reproductive potential of patients
    • Discuss the potential for unintended pregnancy with premenopausal women as therapy may result in ovulation in some anovulatory women
  • Lactation
    • There are no data on the presence of rosiglitazone in human milk, effects on the breastfed infant, or milk production; the 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 the breastfed infant or the underlying maternal condition
