lUNLICENSED USENot licensed for use in children under
12 years for intra-operative bradycardia or by intravenous
route for premedication. Not licensed for use by oral route.
IMPORTANT SAFETY INFORMATION
Antimuscarinic drugs used for premedication to general
anaesthesia should only be administered by, or under
the direct supervision of, personnel experienced in their
use.

lPREGNANCYNot known to be harmful; manufacturer
advises caution.
lBREAST FEEDINGMay suppress lactation; small amount
present in milk—manufacturer advises caution.
lMONITORING REQUIREMENTS
▶Control of muscarinic side-effects of neostigmine in reversal of
competitive neuromuscular blockSince atropine has a shorter
duration of action than neostigmine, late unopposed
bradycardia may result; close monitoring of the patient is
necessary.
lDIRECTIONS FOR ADMINISTRATIONFor administrationby
mouth, injection solution may be given orally.
lEXCEPTIONS TO LEGAL CATEGORY
▶With intramuscular use or intravenous use or subcutaneous
usePrescription only medicine restriction does not apply
where administration is for saving life in emergency.
lMEDICINAL FORMS
There can be variation in the licensing of different medicines
containing the same drug. Forms available from special-order
manufacturers include: oral suspension, oral solution, solution
for injection, solution for infusion
