K2/spice - Felbamate Interaction Details

There are multiple interactions reported between these two agents.

Interaction Details

Felbamate is classified as belonging to the following category: Qt Interval-Prolonging Drugs

Theoretically, K2/spice might have an additive effect with drugs that prolong the QT interval and increase the risk of ventricular arrhythmias.
There have been numerous cases of increased QT and corrected QT intervals in patients using K2/spice.

Interaction Rating

Moderate

Likelihood of Occurrence

Possible

Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists

Interaction Details

Felbamate is classified as belonging to the following category: Anticonvulsants

Theoretically, K2/spice might increase or decrease the effectiveness of anticonvulsant drugs.
Some animal research suggests that certain types of synthetic cannabinoids found in some K2/spice products can potentiate the effects of anticonvulsants. However, seizures have also been reported with inhalation of K2/spice.

Felbamate Overview

Felbamate is used to treat certain seizures in adults and children with epilepsy whose seizures have not improved with other treatments. It is used alone or in combination with other medications to treat partial seizures in adults. It is used in combination with other medications to treat partial and generalized seizures in children with Lennox-Gastaut syndrome (a disorder that causes seizures and developmental delays). Felbamate is in a class of medications called anticonvulsants. It works by decreasing abnormal activity in the brain.
