Uses of Epiphen Tablet
Benefits of Epiphen Tablet
Epilepsy
Epiphen Tablet slows down electrical signals in the brain which cause seizures (fits). 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. Do not stop using this medicine even if you feel well, until your doctor advises you to. Missing doses may trigger a seizure.
