Valproic acid taken with meropenem may result in seizures.(Drug-Drug Interactions)

In addition to its primary use as an antiepileptic agent, valproic acid (Depakene, Depakote) has been used as monotherapy or combined with lithium (Lithobid), carbamazepine (Tegretol) or antipsychotics in the treatment of manic episodes associated with bipolar disorder. Drug interaction with valproic acid is commonly reported, secondary to its ability to inhibit drug elimination, (1) as well as induction of its metabolism by concurrently administered drugs. The carbapenem antibiotics have been reported to interact with valproic acid, resulting in lower valproic acid concentrations and loss of seizure control.
