Anaesthetic disclosure before surgery
Hair transplant surgery normally uses local anaesthetic rather than general anaesthetic. That does not make anaesthetic history irrelevant. Previous dental reactions, palpitations, fainting, suspected allergy, lidocaine sensitivity or adrenaline intolerance should be disclosed before a long procedure day is confirmed.

UK patients should tell the clinic about any previous local anaesthetic reaction, dental injection reaction, lidocaine allergy label, adrenaline palpitations, fainting, panic symptoms, arrhythmia, severe allergy or medication interaction concern. True local anaesthetic allergy is different from adrenaline side effects or vasovagal fainting, so the history should be clarified before travel.
Prepared for medical review. Sources include NHS local anaesthesia guidance and NHS Specialist Pharmacy Service information on reactions and interactions with local anaesthetic injections.
NHS local anaesthetic guidance explains that local anaesthetic numbs a small area and may be given by injection, gel, cream or spray. Hair transplant surgery can require repeated local anaesthetic dosing over a long session. That makes previous reactions, medication list and cardiovascular history relevant.
NHS Specialist Pharmacy Service guidance on dental local anaesthetic reactions describes different possibilities, including adrenaline effects, toxicity, allergy and anxiety-related reactions. Palpitations, shaking, sweating or light-headedness after an injection may not mean true allergy, but they still need to be documented so the team can plan safely.
Local anaesthetic mixtures may include adrenaline to reduce bleeding and prolong effect. Some patients experience palpitations, tachycardia, headache or light-headedness. A patient with arrhythmia, uncontrolled blood pressure, panic attacks, severe anxiety or previous fainting should disclose this rather than waiting until the procedure chair.
If a patient has been told they have lidocaine allergy, had swelling of the throat, breathing difficulty, collapse, severe rash, seizure-like symptoms, suspected toxicity, or a serious reaction requiring emergency care, the case should be clarified before travel. Allergy or anaesthetic review may be needed.
Send the name of the anaesthetic if known, where it was used, what symptoms happened, how quickly they appeared, whether adrenaline was included, whether emergency treatment was needed, current heart medicines, beta-blockers, antidepressants, stimulant medicines and any panic or fainting history.
Decision scenarios
Stable loss, strong donor area, realistic goals, and willingness to follow aftercare usually make planning more reliable.
Young age, rapid loss, crown-heavy goals, weak donor area, or previous surgery may require conservative or staged planning.
Unrealistic expectations, active scalp disease, unmanaged medical risk, or donor overuse concerns can make postponement safer.

Usually yes. Most hair transplant procedures use local anaesthetic, so previous local anaesthetic or dental injection reactions should be disclosed.
Not necessarily. They may relate to adrenaline, anxiety or other causes, but the history still matters and should be clarified before a long procedure.
Only after the history is reviewed. True local anaesthetic allergy is uncommon but important; unclear severe reactions should be assessed before elective surgery abroad.
