Adrenaline + Lidocaine Hydrochloride

Prescribing Information (Research Brand)


This drug is indicated for production of local or regional anesthesia by infiltration techniques such as percutaneous injection, by peripheral nerve block techniques such as brachial plexus and intercostal and by central neural techniques such as lumbar and caudal epidural blocks, when the accepted procedures for these techniques as described in standard textbooks are observed.

Therapeutic Class

Local & Surface anesthesia


Lidocaine is a local anaesthetic which decreases permeability of sodium ions, blocking induction and conduction of nerve impulses. Combination with epinephrine restricts systemic spread of lidocaine, vascular absorption and its duration of local anaesthetic effect.

Dosage & Administration

Dosage depends on several factors such as route, type and extent of surgical procedure, duration of anaesthesia and patient's condition and age.

Adult: Max dose of lidocaine given with epinephrine: 7 mg/kg and not >500 mg.
Child: 3 mth-12 yr: Max dose 3 mg/kg. Ideal body weight should be used in children with high body weight.
