What Is Medical Acupuncture?
Medical acupuncture is the practice of acupuncture by physicians who graduated in medicine, with specialized training in acupuncture and, frequently, in pain medicine or physiatry. Unlike popular acupuncture, the medical modality integrates knowledge of anatomy, neurophysiology, and evidence-based medicine into the system of acupuncture points, allowing for precise indications, adequate differential diagnosis, and safe management of contraindications.
In Brazil, medical acupuncture has been recognized by Brazil's Federal Council of Medicine (CFM) as a medical specialty since 1995 (CFM Resolution No. 1,455/95). The medical acupuncturist can integrate acupuncture with other approaches of conventional medicine — pharmacological prescription, anesthetic blocks, rehabilitation — within an individualized therapeutic plan.
This guide was prepared so that you arrive at your first consultation well informed, without unnecessary anxiety, knowing what to expect at each stage of care.
Before the Session: How to Prepare
Adequate preparation maximizes the benefit of the session and reduces the risk of mild unwanted effects such as transient dizziness or nausea. A few simple measures make all the difference.
Bring recent test results (imaging, laboratory) and a list of medications in use — the physician will need this information for the clinical evaluation and to identify possible interactions or contraindications, such as the use of anticoagulants.
- Light meal 1–2h before: avoid total fasting and very heavy meals
- Stay well hydrated: drink water normally throughout the day
- Loose clothing: easy access to arms, legs, and back facilitates care
- Tests and medications: bring reports, prescriptions, and a list of medications in use
- Avoid alcohol in the previous 12 hours: it may alter vascular response
- Tell the physician about pregnancy, pacemaker, or coagulopathies
The Medical Consultation: Evaluation and Diagnosis
The first medical acupuncture session always begins with a complete medical consultation. Unlike what many patients imagine, the medical acupuncturist does not go directly to the needles — they first conduct a detailed history, physical examination, and, when necessary, request additional tests.
This step is fundamental for defining the clinical diagnosis (not just the symptom), identifying contraindications, establishing realistic treatment goals, and personalizing the points protocol. Medical acupuncture is prescribed — not just applied — and the prescription requires adequate medical evaluation.
Detailed history-taking
The physician investigates the history of the pain or condition, time of evolution, aggravating and relieving factors, previous treatments, and medications in use. Also asks about sleep quality, mood, and level of physical activity.
Targeted physical examination
Postural assessment, palpation of trigger points and tender acupuncture points, joint mobility tests, and brief neurological evaluation when indicated.
Clinical and functional diagnosis
The physician formulates the diagnosis according to ICD codes and, from the medical acupuncture perspective, identifies the patterns of imbalance that will guide point selection.
Treatment planning
The estimated number of sessions, frequency (weekly, biweekly), short- and medium-term goals, and possible complementary treatments (exercise, pharmacology, psychology) are defined.
Informed consent
The physician explains the expected benefits, possible side effects (bruising, mild local pain, drowsiness) and obtains documented consent for the procedure.
During Needling: What You Will Feel
After the evaluation, the physician prepares the patient for needling. The environment is similar to that of a conventional consultation: comfortable exam table, adequate lighting, guaranteed privacy. The physician sanitizes their hands and uses disposable, sterilized needles — single-use, always.
Needle insertion is practically painless at most points: the acupuncture needle has a diameter between 0.16 mm and 0.30 mm, much thinner than a conventional injection needle (0.7–1.2 mm). What the patient may feel is the so-called De Qi sensation — a combination of heaviness, warmth, mild tingling, or gentle distension at the needle site, considered clinically desirable and indicative of point activation.
The number of needles varies according to the protocol: from 4 to 6 needles for simple protocols, reaching 20 or more in complex chronic pain sessions. The needles remain inserted for 20 to 30 minutes in general. During this time, most patients experience deep relaxation — some even fall asleep on the table.
Myth vs. Fact
Acupuncture hurts a lot — it is unbearable
The acupuncture needle is 0.16–0.30 mm in diameter — thinner than a thick strand of hair. Most patients feel only mild pressure or tingling. Intense pain is not expected and should be communicated to the physician immediately.
I can catch diseases from the needles
The needles used are 100% disposable, individually sterilized, and single-use. The package is opened in front of the patient. The risk of infection transmission is virtually zero with this practice.
If I do not feel anything, it did not work
The absence of De Qi does not invalidate the therapeutic effect. Some protocols use points with low density of nerve fibers that produce less sensation. The clinical outcome is the most important criterion.
I must remain absolutely still with the needles
Gentle movements are tolerated. The physician advises on how to position yourself comfortably. If you need to cough, sneeze, or move, inform the physician — the needles can be repositioned.
After the Session: What to Expect in the First 24–48 Hours
The post-session response is quite individual. Some patients feel immediate pain relief — others notice gradual improvement over 24 to 72 hours. Both patterns are normal and depend on the type of condition treated, the general state of the nervous system, and the cumulative number of sessions.
| RESPONSE | FREQUENCY | INTERPRETATION |
|---|---|---|
| Immediate pain relief | Common in acute pain and trigger points | Rapid response to point deactivation — excellent sign |
| Improvement in 24–72h | Common in chronic pain | Neuroplasticity process and central modulation underway |
| Tiredness and drowsiness | Very common (up to 60% of patients) | Normal parasympathetic response — indicates deep activation |
| Mild pain at needle site | Moderately common | Expected microtrauma, resolves in 24–48h. Cold compresses help |
| Small punctate bruise | Occasional, especially with anticoagulants | Benign, resolves in a few days. Inform the physician at the next sessions |
| Transient worsening before improvement | Occurs in 10–20% of cases | Initial exacerbation phenomenon (healing reaction) — transient |
In the hours following the session, adequate hydration is recommended, avoiding intense physical exertion and excessive cold exposure on the treated points. The physician will provide specific guidance according to the protocol used.
How Many Sessions Will I Need?
This is the most frequent question from patients — and the honest answer is: it depends. Treatment duration varies according to the condition (acute vs. chronic), time of evolution, individual response, and therapeutic goals. The physician will establish an estimate at the first consultation, but the protocol will be adjusted according to evolution.
As general guidance, most chronic pain treatments with medical acupuncture follow three phases:
Acute Phase (Relief)
Weeks 1–4- 1–2 sessions per week
- Goal: rapid pain reduction and functional improvement
- Response evaluation after 4–6 sessions
- Point adjustment according to evolution
Stabilization Phase
Weeks 5–12- 1 session per week or biweekly
- Goal: consolidate relief and prevent relapses
- Introduction of exercises and habit changes
- Progressive reduction of session frequency
Maintenance Phase
From the 3rd month- 1 monthly session or as needed
- Goal: maintain the gains achieved
- Treatment of occasional flare-ups
- Possibility of even greater spacing with good response
For acute conditions (such as occasional tension headache or low back pain crisis), a cycle of 4 to 6 sessions may be sufficient. For chronic pain of long evolution (fibromyalgia, neuropathic pain, osteoarthritis), treatment tends to be more prolonged. See the full article: How many acupuncture sessions are needed?
Step by Step: What Happens at the First Consultation
To demystify the process, see the complete flow of a first medical acupuncture session — from arrival to leaving the office.
Reception and intake form (5–10 min)
Filling out a form with health data, medications in use, disease history, and chief complaint. This form guides the medical consultation.
Medical consultation — history and physical exam (20–30 min)
The physician deepens the clinical history, performs a targeted physical examination, and reviews tests. Establishes the diagnosis and explains the treatment plan.
Positioning and preparation (5 min)
The patient is positioned on the table according to the points to be used (supine, prone, or seated). The area is sanitized with 70% alcohol.
Needle insertion (5–10 min)
The physician inserts the needles one by one, observing the patient response. May perform manipulations (rotation, lifting) to stimulate De Qi.
Rest with needles (20–50 min)
The patient rests with needles inserted. During this period, electrical stimulation (electroacupuncture) or heat (moxibustion) may be applied, depending on the protocol.
Needle removal and final guidance (5 min)
The needles are removed gently. The physician advises on post-session care, hydration, physical activity, and schedules the next appointment.
Which Conditions Are Treated With Medical Acupuncture?
Medical acupuncture has evidence-based indications for a broad spectrum of conditions, with emphasis on chronic and acute pain. A 2003 WHO review document compiled clinical trials for more than 100 conditions; it is worth noting that this document does not represent an official endorsement list, and more recent guidelines focus on specific indications with a stronger evidence base (chronic musculoskeletal pain, headache, nausea, among others).
It is important to emphasize that acupuncture is rarely used as the sole treatment. The medical acupuncturist integrates it into a therapeutic plan that may include pharmacology, prescribed exercise, psychology, and other interventions — always with the patient at the center of decisions.
- Chronic musculoskeletal pain: low back, neck, shoulder, knee — grade A evidence
- Tension headache and migraine: reduction in frequency and intensity — grade A evidence
- Fibromyalgia: improvement of pain, sleep, and quality of life — grade B evidence
- Cancer pain: complementary to conventional analgesia — grade B evidence
- Anxiety and insomnia: symptom reduction — growing evidence
- Nausea and vomiting after chemotherapy: PC6 point with robust evidence — grade A evidence
Contraindications and Precautions
Medical acupuncture is a safe procedure when practiced by a qualified physician with disposable needles. However, like any medical intervention, it has contraindications and situations that require special care.
Precautionary situations (not absolute contraindications, but require protocol adaptation):
- Anticoagulants (warfarin, heparin, direct oral anticoagulants): increased risk of bruising — use thinner needles and apply local pressure after removal
- Cardiac pacemaker: contraindication to electroacupuncture in the thoracic region, not to plain acupuncture
- Severe immunosuppression (neutropenia <500): increased infectious risk — strict hygiene and reduced protocols
- Hemophilia and coagulopathies: possible with thin needles and prolonged pressure after removal
- Intense fear of needles (belonephobia): progressive approach, minimal techniques, or auriculotherapy with seeds as initial alternative
Frequently Asked Questions
Yes, with caution. Pregnancy does not contraindicate acupuncture, but some points are contraindicated (especially LI-4, SP-6, pelvic, and lumbosacral points) due to potential uterine stimulation. A medical acupuncturist with experience in pregnancy will know which protocols are safe for each trimester.
Yes, in most cases. The physician will use thinner needles, avoid highly vascular points, and apply pressure to the site after removal. Always inform the physician about all medications in use, including aspirin and anti-inflammatories.
There is no established age limit. In children, the physician may use adapted techniques (thinner needles, reduced time, auriculotherapy with seeds instead of needles). In the elderly, acupuncture is particularly useful as an alternative or complement to pharmacology, reducing medication burden.
Frequently Asked Questions
Frequently Asked Questions
Coverage varies by insurer and plan. After the ANS resolution that expanded coverage of integrative practices in 2018, many plans began covering acupuncture. Check directly with your insurer. In some cases, the medical consultation is covered but the procedure (needling) is not — or vice versa.
The number varies according to the protocol and the condition treated — generally between 6 and 20 needles per session. Auriculotherapy protocols use fewer needles (4–8); complex systemic protocols may use more. The physician determines the ideal number for each situation.
Yes, and it is often ideal. Medical acupuncture is most effective when integrated with other treatments: prescribed physical exercise, adequate pharmacology, psychotherapy for chronic pain. The medical acupuncturist coordinates this integration and may refer to other specialists as needed.
It depends on the condition. In acute pain (isolated trigger points, low back pain crisis), improvement tends to be lasting with few sessions. In chronic pain of long evolution, acupuncture controls and reduces pain, but periodic maintenance may be necessary. Habit changes (exercise, ergonomics, adequate sleep) are decisive for the durability of results.
Yes, in most cases. Some patients feel drowsiness in the first sessions — if this is your profile, organize your schedule to have rest time after the consultation. For the first session especially, avoid immediate commitments that require high concentration, until you know your individual response.
Acupuncture has no direct pharmacological interactions (no substances are ingested). However, needling in patients on anticoagulants requires special technical care. In addition, as pain improves with treatment, the physician may reconsider doses of analgesics and anti-inflammatories — acupuncture may allow for a reduction in medication burden.
