It contends Kerry used the wrong formula of the drug and prescribed an IV push — meaning the drugs are administered in one dose intravenously — despite warnings that it could be lethal.

Kerry has not commented publicly on the various allegations he faces, but has defended his treatment of the boy in documents contesting the Department of State’s charges.

He has argued that the boy’s autism symptoms improved after the first two treatments earlier in the summer of 2005. Kerry acknowledged that there may have been a “miscommunication” about which medication to give the boy during the third treatment, but says that did not amount to repeated or gross negligence.

A Department of State spokeswoman said the criminal charges do not change plans to hold a disciplinary hearing this fall that could result in Kerry’s license being suspended or revoked.
