Can a Medical Assistant Administer Sclerotherapy?

I would recommend a board certified surgeon who is a diplomate of the American Board of Phlebology (Vein Surgery).

Depending on the state, laws are different in terms of who can inject medications. In NY state only licensed individuals may, and this excludes an M.A. (medical assistant). I would encourage you to contact the state board of medicine in California to ask them this question.

Medical assistants are, in the current medical atmosphere, doing more and more medical procedures.  Each state had regulations as to who can do what.  Medical assistants consists of physician assistants, nurse PA's, nurses and medical technicians.  All of them need to work under a physician's supervision. If you to have sclerotherapy done by a medical assistant then you should inquire about their training and experience.  If you are uncomfortable with them then ask for treatment by the doctor.
