In the hands of certified practitioners, acupuncture is a very safe form of treatment. Needles used for acupuncture are sterile, single-use stainless steel implements that are promptly discarded after use.
There are minimal adverse effects and complications that arise from the use of acupuncture, however any procedure involving the insertion of needles comes with potential problems.

Some side effects that you may experience include:

• Slight discomfort as the needles are inserted
• Drowsiness
• Feeling faint
• Localized bruising and/or soreness
• Temporary worsening of symptoms

Some risks, though very rare, can include:

• Damage to an internal organ from insertion of a needle
• Infection at the site of insertion
• Premature onset of labour in late stage pregnancy

It is recommended that the patient relax for an additional 15-30 mins after treatment so that the practitioner can monitor and ensure no adverse reactions develop.
