Anticonvulsants such as felbamate should be prescribed in the smallest quantity consistent with good patient management in order to reduce the risk of overdose.
Guidance is not available regarding frlbamate use of cobimetinib with weak CYP3A inducers. Monitor for a decrease in maraviroc efficacy with concomitant use.
Monitoring should include baseline pacckage function tests i. Moderate Concurrent use of topiramate and drugs that cause thrombocytopenia such as the anticonvulsant felbamate may increase the risk of bleeding. Major Felbamate may reduce the antiplatelet activity of clopidogrel by inhibiting clopidogrel’s metabolism to its active metabolite.
Felbamate may interfere with valproic acid metabolism and should be administered cautiously to patients receiving valproic acid.
The drug is not recommended for children under the age of 2 years or in infants.
There were 4 completed suicides among patients in drug treatment groups versus none in the placebo groups. It is thought that hepatic failure in felbamate-treated patients greatly exceeds that which occurs in the general population. Anticonvulsants may cause liver dysfunction, blood dyscrasias, and serious skin rashes requiring treatment discontinuation.
Adolescents and Children 2 – 14 years. Too little is known about felbamate-induced aplastic anemia to determine fatality percentages or which patients are more at risk for this serious adverse reaction. Major In vitro and drug interactions studies suggest that the CYP3A4 isoenzyme is the major enzyme involved in praziquantel metabolism.
Major Avoid coadministration of isavuconazonium with felbamate. Serum concentrations of other anticonvulsants should be obtained and dosage adjustments made as necessary. However, this is considered to be a class effect. Belladonna Alkaloids; Ergotamine; Phenobarbital: Monitoring of the anticonvulsant serum concentration is recommended. The effect of food on GI absorption from the oral suspension has not been evaluated.
Use of these drugs isnert may decrease the plasma concentrations of both elbasvir and grazoprevir, and could result in decreased virologic response.
Patients should be advised to be alert for signs of liver dysfunction jaundice, anorexia, gastrointestinal complaints, malaise, etc. Estrogens are metabolized by CYP3A4. Because of the serious toxicities associated with the drug, including aplastic anemia pcakage hepatic failure, breast-feeding should generally be avoided during treatment with felbamate.
Major Based on very limited data, it appears felbamate can accelerate the clearance of the estrogen component of some oral contraceptives. Moderate Use caution during concurrent use of vorapaxar and felbamate. Send the page ” ” to a friend, relative, colleague or yourself. Clinical signs and symptoms may include infection, bleeding, or anemia. It is not teratogenic in animal models. Moderate The phenothiazines, when used concomitantly with felbamatr, can lower the seizure threshold.
Major Coadministration of felbamate and clarithromycin may decrease clarithromycin serum concentrations due to CYP3A4 enzyme induction.
Felbamate is an inducer of CYP3A, dolutegravir is partially metabolized by this isoenzyme. It is not clear if clarithromycin activity against other organisms would be packsge, but reduced efficacy is possible.
Proper intake of folic acid should also be ensured. If these drugs are administered concurrently, monitor the patient for signs of lack of efficacy of rivaroxaban. Patients must call to enroll in the registry. Moderate Additive CNS depression can occur if ethanol is consumed while taking felbamate.
If use together is necessary, obtain an ECG prior to lacosamide initiation and after treatment has been titrated to steady-state. Dasabuvir; Ombitasvir; Paritaprevir; Ritonavir: Determining effectiveness and tolerability through evaluation of symptoms should be used to adjust doses. In a pooled analysis of placebo-controlled trials, bleeding was more frequently reported in patients receiving topiramate 4.
Inxert Avoid concurrent use of felbamate with bedaquiline. If felbamate must be used, consider reducing use of other CNS-active medications that increase the risk of falls and fractures and implement other strategies to reduce fall risk. The anticonvulsants mentioned may cause oral contraceptive failure, especially when low-dose estrogen regimens e. Moderate Consistent with the pharmacology of molindone, additive effects may occur with other CNS active drugs such as anticonvulsants.
Age was not a determining factor. Coadministration may decrease the plasma concentrations of ivabradine resulting in the potential for treatment failure. Concomitant use may result in decreased plasma concentrations of dronabinol.
Predictions about the interaction can be made based on the metabolic pathways of both drugs.
Felbatol (felbamate) dose, indications, adverse effects, interactions from
Although this interaction has not been studied by the manufacturer, and published literature suggests the potential for interactions to be low, taking these drugs together may alter the systemic exposure of terbinafine. Felbamate is contraindicated in patients with a felbamate or carbamate hypersensitivity.
This alert followed an initial request by the FDA in March for manufacturers of marketed anticonvulsants to provide data from existing controlled clinical trials for analysis. Moderate Use lacosamide with caution in patients taking concomitant medications that affect cardiac conduction including those that prolong PR interval, such as sodium channel blocking anticonvulsants e.
Major Coadministration of felbamate with cobicistat is not recommended. Adverse effects, such as sedation, lethargy, ataxia, or insomnia may be potentiated. Moderate The plasma concentration and efficacy of loperamide may be reduced when administered concurrently with felbamate.
