seizures
"I will be 50 next week so the hair loss may be due to menopause although I am having no other signs of this (still have regular cycles, no hot flashes, etc.). And this came on so quickly; as soon as I started taking Vimpat so I feel there may be a connection. Started 400 mg in November and had terrible insomnia/tremors so I was cut back to 300. I did not have a reduction in the number of seizures (4 partial a month) but the severity has reduced greatly. However my hair is falling out at an unbelievable pace. I am so happy for the reduction in seizure severity I will buy a wig if needed. Just wanted to mention for anyone else who may be facing this as it is not a listed side effect. Also 8 lb weight loss and still a bit anxious."
