What Are Warnings and Precautions for Gadoterate Meglumine?
Contraindications
- Hypersensitivity
Effects of drug abuse
- None
Short-Term Effects
- See “What Are Side Effects Associated with Using Gadoterate Meglumine?”
Long-Term Effects
- See “What Are Side Effects Associated with Using Gadoterate Meglumine?”
Cautions
- Gadolinium-based contrast agents increase the risk for NSF among patients with impaired elimination (see Black Box Warnings)
- Anaphylactic and anaphylactoid reactions reported and may involve cardiovascular, respiratory, and/or cutaneous manifestations, including reports of patients experiencing cardiovascular collapse and death
- Acute kidney injury requiring dialysis has occurred in patients with chronically reduced renal function
- Gadolinium retention
- Gadolinium is retained for months or years in several organs
- Highest concentrations (nanomoles per gram of tissue) have been identified in the bone, followed by other organs (.g, brain, skin, kidney, liver, and spleen)
- Duration of retention also varies by tissue and is longest in bone
- Patients requiring multiple lifetime doses, pregnant and pediatric patients, and patients with inflammatory conditions are at higher risk of gadolinium retention
- Brain deposits
- FDA investigated the risk of brain deposits following repeated use of GBCAs for MRI in 2015
- Publications in the medical literature have reported that deposits of GBCAs remain in the brains of some patients who undergo above 4 contrast MRI scans, long after the last administration
- As of 2017, the FDA review had not identified adverse health effects from gadolinium retained in the brain after the use of GBCAs MRI; all GBCAs may be associated with some gadolinium retention in the brain and other body tissues
- Early data in rat studies show that linear GBCAs are more prone to dissociation into free gadolinium and demonstrate greater brain deposition than macrocyclic GBCAs, which are less prone to dissociation
Pregnancy and Lactation
- GBCAs cross the placenta and result in fetal exposure and gadolinium retention
- Human data on the association between GBCAs and adverse fetal outcomes are limited and inconclusive
- estimated background risk of major birth defects and miscarriage for the indicated population is unknown
- All pregnancies have a background risk of birth defect, loss, or other adverse outcomes
- Lactation
- Estimated infant exposure is 0.001%-0.04% of the maternal dose
- Unknown whether the effects of the drug on the breastfed infant or the effects the drug on milk production
- Developmental and health benefits of breastfeeding should be considered together with the mother’s clinical need for the drug and any potential adverse effects on the breastfed infant or from the underlying maternal condition
