Acupuncture Side Effects and Safety — what's common, what's rare.

Acupuncture side effects have been counted more carefully than most people assume. Instead of collecting alarming stories after the fact, several large prospective surveys asked practitioners or patients to log every reaction as it happened, across tens of thousands of treatments. Their findings agree on the shape of the risk: small reactions at the needle site are fairly frequent, and serious ones are rare.

The York acupuncture safety study, published in the BMJ (British Medical Journal) in 2001, asked traditional acupuncturists to record 34,407 treatments. They reported no serious adverse events and 43 minor ones — 1.3 per 1,000 treatments — the most common being severe nausea and fainting. Alongside those, practitioners logged milder passing reactions in 15% of treatments, and the 2 most frequent were not complaints at all: patients felt relaxed (11.9%) or energized (6.6%).

A companion survey published alongside it covered 31,822 consultations with doctors and physiotherapists who practice acupuncture. Again there were no serious events. The most common minor ones were bleeding (310 per 10,000 consultations) and pain from needling (110 per 10,000), followed by a temporary aggravation of symptoms (96 per 10,000).

The biggest dataset comes from a 2009 study in the journal Forschende Komplementärmedizin, which followed 229,230 patients treated by physicians, averaging about 10 treatments each. Over the whole course, 8.6% reported at least one adverse effect and 2.2% needed treatment for one. Bleeding or hematoma — a small pocket of blood under the skin — made up most of them, at 6.1% of patients. The study recorded 2 cases of pneumothorax, a punctured lung, and its longest-lasting problem was a nerve injury that persisted for 180 days.

Per treatment or per patient?

Notice the different yardsticks. A rate per patient across 10 sessions will always look larger than a rate per treatment, because every session is another chance for a bruise. Neither number is wrong; they answer different questions. For a first visit, the per-treatment figures are the relevant ones.

Sterile, single-use needles and proper training are the 2 variables the safety literature keeps returning to. The National Center for Complementary and Integrative Health (NCCIH) puts it plainly: relatively few complications from acupuncture have been reported, but complications have resulted from non-sterile needles and improper delivery of treatment, including infections, punctured organs and injury to the central nervous system.

What the FDA requires of a needle

The U.S. Food and Drug Administration (FDA) regulates acupuncture needles as medical devices. Under federal regulation 21 CFR 880.5580 they are Class II devices with special controls covering sterility, biocompatible materials, labeling for single use only, and the rules for prescription devices. NCCIH summarizes the practical result: needles must be sterile and labeled for single use only.

Single use matters because of history. In the 2004 review, infection accounted for hundreds of case reports, and more than 60% of them were hepatitis B, a bloodborne virus. At Harmony, every needle is sterile and single-use and is discarded after your session.

What a Virginia license means

Virginia makes it unlawful to practice acupuncture, or to present yourself as an acupuncturist, without a license issued by the Board of Medicine (Code of Virginia § 54.1-2956.9). To renew in active status, the Board requires current certification from the National Certification Commission for Acupuncture and Oriental Medicine (NCCAOM). Licenses are public: the Department of Health Professions' free License Lookup lists licensed acupuncturists and can be searched by name. Ask for your practitioner's name and look them up — at any clinic, ours included.

The same questions apply to dry needling, which uses the same kind of filiform needle; our dry needling vs. acupuncture comparison covers how the training and licensing behind the two differ.

Reporting a problem after acupuncture runs on two tracks: your health first, then the record. Most reactions need nothing more than a phone call, but a few need medical care straight away, and a smaller number deserve a formal report so that a regulator can look at the practitioner or the product involved.

1. Get care first if you need it. MedlinePlus lists sharp chest or shoulder pain made worse by a deep breath or a cough, and shortness of breath, as symptoms of a collapsed lung. If those follow needling near the chest, shoulders or upper back, go to urgent care — or call 911 if breathing is hard. For spreading redness, warmth, discharge or fever at a needle site, call your doctor.
2. Tell the clinic. Call or text us at 240-715-5939 with what happened and when — whether it is a bruise you want to ask about or something more.
3. Tell your own doctor. Any reaction that needed treatment belongs in your medical record, along with when and where the acupuncture happened.
4. Report a practitioner concern. The Virginia Department of Health Professions' Enforcement Division receives complaints about licensed health care practitioners, acupuncturists included; its phone line is 1-800-533-1560.
5. Report a faulty needle. A package that arrives open or a needle that breaks is a device problem; the FDA's MedWatch program takes reports from the public online or at 1-888-463-6332.

Sensation is not injury

Part of what feels wrong during a first session is simply unfamiliar. A dull ache, heaviness or spreading warmth around a needle is a sensation many people report, and it is different from sharp or lasting pain. Our guide to whether acupuncture hurts covers what needling normally feels like, so you can tell the two apart — and if you are unsure, say so on the table rather than afterward.
