seizures
"Make sure you are getting a factory sealed bottle! VIMPAT only has a shelf life of 7 weeks once opened. We were getting VIMPAT dispensed from a larger opened bottle at our pharmacy. This bottle may have been open well outside of the shelf life per VIMPAT guidelines. We changed the prescription over to another pharmacy and started to receive an factory sealed bottle. 

I mentioned this because during the time of receiving VIMPAT from original pharmacy our 3 year old myoclonic seizure activity was not controlled. Our Doctor couldn't believe the VIMPAT wasn't working and increased dosage slowly. When we switched over to new ones (sealed bottle) the seizures stopped immediately and he has been seizure free for 3 weeks now."
