RENO — The Nevada State Board of Medical Examiners is set to review regulations to let medical assistants provide antibiotic and vaccine injections for patients.

The board scheduled an emergency meeting Friday in Reno after board executive Louis Ling issued a warning to physicians not to let medical assistants handle patient injections of the anti-wrinkle drug Botox.

Ling cited a law that has been on the books since 1979, but that officials say was widely disregarded.

Nevada Gov. Jim Gibbons this week endorsed a proposal to tighten controls over who can administer Botox, cosmetics and other drugs, while letting medical assistants deliver flu shots, vitamins and other medicines.

Gibbons spokesman Daniel Burns says that with flu season approaching, the governor doesn't want people to have trouble getting vaccine shots.
