Consult an ophthalmologist in case of complaints.
After swallowing: Not applicable.
Information for doctor:
Catecholamines such as adrenaline, and other compounds having similar effects, should be reserved for emergencies
and then used only with special caution.
The examining physician should advise workers taking medications containing catecholamines that they may be atincreased risk and should avoid excessive exposure.
