Benefits of Cnlev Tablet

In Treatment of Epilepsy/Seizures

Cnlev 500mg Tablet belongs to a group of medicines called anticonvulsants (or anti-epileptics). It works by slowing down electrical signals in the brain which cause seizures (fits). This medicine can be used to control various types of seizures—myoclonic, partial-onset, and primary generalized tonic-clonic (or grand mal). It can also help reduce symptoms such as confusion, uncontrollable jerking movements, loss of awareness, and fear or anxiety. The medicine can allow you to do some activities that you would otherwise be forbidden or scared to do (such as swimming and driving). It can take a few weeks for this medicine to work (because the dose has to be increased slowly) and during this time you may still have seizures. You should continue taking it even if you feel well and are not having any seizures. Missing doses may trigger a seizure. Do not stop using this medicine until your doctor advises you.
