I just found out my 21 y/o daughter has been taking half of her doctor ordered dose in order to save MONEY! She is on lamictal, works 2 jobs, has health insurance, but Lamictal is a third tier drug for them and costs $5 a pill in the US. I bought her Zarontin (she was on that from age 3-10) before from a pharmacy in Canada. She is now buying her lamical in Canada. If you email me privately I will give you the email of that company. The neuro saw her Wednesday and told her that, at her current dose of 150mg a day (she's supposed to be on 150mg TWICE a day) that she is on less than what the neuro gives her migraine patients!!, and that she is putting herself in danger. I wonder if permanent brain damage can occur from doing this?
