Hypersensitivity to local anaesthetics of amide type. IV regional anaesthesia; paracervical block in obstetrics; spinal anaesthesia <18 yr. Lactation. Solutions containing preservatives for caudal or epidural block.
Bupivacaine blocks both the initiation and conduction of nerve impulses reducing the permeability of neuronal membranes to Na ions resulting in inhibition of depolarization w/ resultant blockade of conduction.
Hepatic disease; CV disease; children <12 yr; pregnancy. Elderly and debilitated patients. Lactation: excretion in milk unknown/not recommended
CNS excitation may be followed by depression. Hypotension, bradycardia, arrhythmias and cardiac arrest; methaemoglobinaemia; seizures, restlessness, dizziness. Hypersensitivity. Prolonged block, Edema, Headache, Hypotension, Hypoventilation, Nausea, Nervousness, Palpitation, Respiratory arrest, Tachycardia, Tinnitus, Tremors, Vomiting Potentially Fatal: Cardiac and sudden respiratory arrest.
Pregnancy Category: C Lactation: excretion in milk unknown/not recommended
Additive systemic toxic effect w/ other local anaesth or agents structurally related to amide-type local anaesth (e.g. lidocaine and mexiletine). Increased risk of myocardial depression w/ antiarrhythmics. Enhanced adverse effects w/ hyaluronidase. Decreased clearance resulting to increased plasma concentrations w/ cimetidine and ranitidine. Increased risk of adverse effects w/ beta-blockers and Ca channel blockers.
