When practiced by a licensed, trained acupuncturist, acupuncture is extremely safe. As a system of health care, acupuncture already has some inherent safeguards. Because the treatment is drug-free, patients do not have to worry about taking several doses of a medication or suffering a possible adverse reaction. Properly administered, acupuncture does no harm. However, there are certain conditions you should notify an acupuncturist about before undergoing treatment. If you have a pacemaker, for instance, you should not receive electroacupuncture due to the possibility of electromagnetic interference with the pacemaker. Similarly, if you have a tendency to bleed or bruise easily, or if you are a hemophiliac, you may want to consider a different type of care.
