Hi gypsyrose,
Keppra can sometime cause a person to be very moody and have a hot temper. My neuro wanted me to take the drug but I refused to because of the side effects. To get a full detail of the side effects of keppra check out Drugs on the right corner of your screen and it will give you all the detail you need to know. Here's wishing you the best of luck and May God Bless You!
