g 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.
Molindone: Consistent with the pharmacology of molindone, additive effects may occur with other CNS active drugs such as anticonvulsants. In addition, seizures have been reported during the use of molindone, which is of particular significance in patients with a seizure disorder receiving anticonvulsants. Adequate dosages of anticonvulsants should be continued when molindone is added; patients should be monitored for clinical evidence of loss of seizure control or the need for dosage adjustments of either molindone or the anticonvulsant.
Mometasone: 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.
Monoamine oxidase inhibitors: MAOIs can cause a variable change in seizure patterns, so careful monitoring of the patient with epilepsy is required. Also, additive CNS depression is possible if MAOIs and anticonvulsants are coadministered.
Nortriptyline: Tricyclic antidepressants, when used concomitantly with anticonvulsants, can increase CNS depression and may also lower the seizure threshold.
Orlistat: Seizures have been reported in patients treated concomitantly with orlistat and anticonvulsants. Patients should be monitored for possible changes in the frequency and/or severity of convulsions. A mechanism for the potential interaction has not been stated.
Pemoline: A reduction in seizure threshold has been reported following concomitant administration of pemoline with anticonvulsant agents. Dosage adjustments of anticonvulsants may be necessary during simultaneous use of these drugs.
Perphenazine: The phenothiazines, when used concomitantly with anticonvulsants, can lower the seizure threshold. Adequate dosages of anticonvulsants should be continued when a phenothiazine is added.
Perphenazine; Amitriptyline: The phenothiazines, when used concomitantly with anticonvulsants, can lower the seizure threshold. Adequate dosages of anticonvulsants should be continued when a phenothiazine is added. Tricyclic antidepressants, when used concomitantly with anticonvulsants, can increase CNS depression and may also lower the seizure threshold.
Phenelzine: MAOIs can cause a variable change in seizure patterns, so careful monitoring of the patient with epilepsy is required. Also, additive CNS depression is possible if MAOIs and anticonvulsants are coadministered.
Phenothiazines: The phenothiazines, when used concomitantly with anticonvulsants, can lower the seizure threshold. Adequate dosages of anticonvulsants should be continued when a phenothiazine is added.
Phentermine; Topiramate: Concurrent use of topiramate and drugs that cause thrombocytopenia such as the anticonvulsant levetiracetam, may increase the risk of bleeding. In a pooled analysis of placebo-controlled trials, bleeding was more frequently reported in patients receiving topiramate (4.5%) compared to placebo (2 to 3%). In those with severe bleeding events, patients were oft |
