Warnings
Hypersensitivity reactions have been reported, including fatalities; these reactions are more likely to occur in individuals with history of sensitivity to multiple allergens
Seizures have been reported, most commonly in patients with CNS disorders (eg, brain lesions, history of seizures) or with bacterial meningitis or compromised renal function
Seizures, headaches, or paresthesias may occur, potentially interfering with mental alertness or causing motor impairment
Clostridium difficile-associated diarrhea has been reported
To avoid development of drug resistance, drug should be used only in proven or strongly suspected bacterial infections or a prophylactic indication
Prolonged use may result in overgrowth of nonsusceptible organisms
Thrombocytopenia has been reported in patients with renal impairment
Co-administration of meropenem IV with valproic acid or divalproex sodium reduces serum concentrations of valproic acid potentially increasing risk of breakthrough seizures
Severe cutaneous adverse reactions (SCAR) such as Stevens-Johnson syndrome (SJS), toxic epidermal necrolysis (TEN), drug reaction with eosinophilia and systemic symptoms (DRESS), erythema multiforme (EM) and acute generalized exanthematous pustulosis (AGEP) reported; if signs and symptoms suggestive of these reactions appear, therapy should be withdrawn immediately and an alternative treatment considered
Pregnancy and Lactation
There are insufficient human data to establish whether there is a drug-associated risk of major birth defects or miscarriages with meropenem in pregnant women
Drug has been reported to be excreted in human milk; no information is available on effects of drug on breast-fed child or on milk production
