Do not inject intravascularly. As for other injectable medical devices inadvertent injection into blood vessels could potentially lead to vascular occlusion, ischemia and necrosis.
If the overlying skin turns a whitish colour (blanching), the injection should be stopped immediately and the area massaged until it returns to a normal colour.
Do not use in patients with bleeding disorders or in patients who are taking thrombolytics or anticoagulants.
Do not resterilize.
Do not mix with other products prior to injection of the device.
Do not use in patients with known hypersensitivity to lidocaine or to amide-type local anaesthetics.
