What do we know about the effectiveness of acupuncture?
Research suggests that acupuncture can help manage certain pain conditions, but evidence about its value for other health issues is uncertain.
What do we know about the safety of acupuncture?
Acupuncture is generally considered safe when performed by an experienced, well-trained practitioner using sterile needles. Improperly performed acupuncture can cause serious side effects.
What the Science Says About the Effectiveness of Acupuncture
Results from a number of studies suggest that acupuncture may help ease types of pain that are often chronic such as low-back pain, neck pain, and osteoarthritis/knee pain. It also may help reduce the frequency of tension headaches and prevent migraine headaches. Therefore, acupuncture appears to be a reasonable option for people with chronic pain to consider. However, clinical practice guidelines are inconsistent in recommendations about acupuncture.
The effects of acupuncture on the brain and body and how best to measure them are only beginning to be understood. Current evidence suggests that many factors—like expectation and belief—that are unrelated to acupuncture needling may play important roles in the beneficial effects of acupuncture on pain.
What the Science Says About Safety and Side Effects of Acupuncture
- Relatively few complications from using acupuncture have been reported. Still, complications have resulted from use of nonsterile needles and improper delivery of treatments.
- When not delivered properly, acupuncture can cause serious adverse effects, including infections, punctured organs, collapsed lungs, and injury to the central nervous system.
NCCIH funds research to evaluate acupuncture’s effectiveness for various kinds of pain and other conditions, and to further understand how the body responds to acupuncture and how acupuncture might work. Some recent NCCIH-supported studies are looking at:
- If acupuncture can reduce the frequency of hot flashes associated with menopause
- Whether acupuncture can reduce pain and discomfort that may accompany chemotherapy
- Objectively determining if actual acupuncture is more effective than simulated acupuncture or usual care for pain relief, and (if so) by how much.
More to Consider
- Don’t use acupuncture to postpone seeing a health care provider about a health problem.
- If you decide to visit an acupuncturist, check his or her credentials. Most states require a license, certification, or registration to practice acupuncture; however, education and training standards and requirements for obtaining these vary from state to state. Although a license does not ensure quality of care, it does indicate that the practitioner meets certain standards regarding the knowledge and use of acupuncture. Most states require a diploma from the National Certification Commission for Acupuncture and Oriental Medicine for licensing.
- Some conventional medical practitioners—including physicians and dentists—practice acupuncture. In addition, national acupuncture organizations (which can be found through libraries or by searching the Internet) may provide referrals to acupuncturists. When considering practitioners, ask about their training and experience.
- Ask the practitioner about the estimated number of treatments needed and how much each treatment will cost. Some insurance companies may cover the costs of acupuncture, while others may not. For more information, see NCCIH’s fact sheet Paying for Complementary Health Approaches.
- Help your health care providers give you better coordinated and safe care by telling them about all the health approaches you use. Give them a full picture of what you do to manage your health.
