Due to a head injury,I am succeptable to seizures.I have been taking Lamictal for over a year. Initially I started with 300 mgs daily.It did not work effectively,so my doctor raised the dosage to 400 milligrams per day.I asked the doctor what are the side effects?He replied that tere are none. He said in fact "it stimulates the brain."I replied "how could any medication that deters seizures not have any side effects"?? At this point I am frequently constipatedI get rashes.I also am extremely forgetful terrible memory & cannot get my words out that I had no problem with while taking dilantin.I stopped dilantin, although it worked effectively, due it's terrible side effects& constantly having gum problems
