Madam Chair, if I'm not mistaken, some epilepsy drugs have been among the drugs for which there have been shortages. You've probably looked at this issue as a committee, or heard about it. When a drug suddenly goes out of production for a period of time, from what I've heard--and I'm sure you have heard it as well--it can have a great impact on patients, who normally would need time to shift gradually from one drug to another but don't have time to do that in the case of a sudden shortage.
