corticosteroids must be used together.
Bupropion: Bupropion should not be used by patients with a preexisting seizure disorder. Buproprion may lower the seizure threshold. Bupropion may also interact pharmacokinetically with anticonvulsant drugs that induce hepatic microsomal isoenzyme function such as carbamazepine, barbiturates, or phenytoin, as well as fosphenytoin, ethotoin.
Bupropion; Naltrexone: Bupropion should not be used by patients with a preexisting seizure disorder. Buproprion may lower the seizure threshold. Bupropion may also interact pharmacokinetically with anticonvulsant drugs that induce hepatic microsomal isoenzyme function such as carbamazepine, barbiturates, or phenytoin, as well as fosphenytoin, ethotoin.
Carbamazepine: Carbamazepine toxicity, unrelated to elevated concentrations of carbamazepine or the epoxide, may occur when levetiracetam is added to carbamazepine therapy. The interaction appears to be pharmacodynamic in nature rather than pharmacokinetic. Toxicity was reversed when the dose of carbamazepine was reduced.
Chlorpromazine: The phenothiazines, when used concomitantly with anticonvulsants, can lower the seizure threshold. Adequate dosages of anticonvulsants should be continued when a phenothiazine is added.
Clomipramine: Tricyclic antidepressants, when used concomitantly with anticonvulsants, can increase CNS depression and may also lower the seizure threshold.
Colesevelam: Colesevelam may decrease the bioavailability of levetiracetam if coadministered. To minimize potential for interactions, consider administering oral anticonvulsants such as levetiracetam at least 1 hour before or at least 4 hours after colesevelam.
Corticosteroids: Concomitant use of systemic sodium chloride, especially at high doses, and corticosteroids may result in sodium and fluid retention. Assess sodium chloride intake from all sources, including intake from sodium-containing intravenous fluids and antibiotic admixtures. Carefully monitor sodium concentrations and fluid status if sodium-containing drugs and corticosteroids must be used together.
Corticotropin, ACTH: Concomitant use of systemic sodium chloride, especially at high doses, and corticosteroids may result in sodium and fluid retention. Assess sodium chloride intake from all sources, including intake from sodium-containing intravenous fluids and antibiotic admixtures. Carefully monitor sodium concentrations and fluid status if sodium-containing drugs and corticosteroids must be used together.
Cortisone: Concomitant use of systemic sodium chloride, especially at high doses, and corticosteroids may result in sodium and fluid retention. Assess sodium chloride intake from all sources, including intake from sodium-containing intravenous fluids and antibiotic admixtures. Carefully monitor sodium concentrations and fluid status if sodium-containing drugs and corticosteroids must be used together.
Desipramine: Tricyclic antidepressants, when used concomitantly with anticonvulsants, can increase CNS depression and may also lower the seizure threshold.
Dexamethasone: Concomitant use of systemic sodium chloride, especially at high doses, and corticosteroids may result in sodium and fluid retention. Assess sodium chloride intake from all sources, including intake from sodium-containing intravenous fluids and antibiotic admixtures. Carefully monitor sodium concentrations and fluid status if s |
