This page is to help me remember loading doses for various anti-epileptic medications. Use the info here at your own risk. If you use this without knowing what you're doing, well then you're an idiot and shouldn't be treating patients. For the medications below missing doses, it means I have no official source for them. If you have a source that describes a loading dose or regimen, please email me using your own email program or directly from this website.
