* Lidocaine use for local anesthesia (e.g. by dentists) does seem to be safe if the amount administrated is low and if it is combined with adrenaline (epinephrine) which results in a local effect only.

Further, in case of fever, close (electrocardiographic) monitoring is appropriate in combination with
lowering of the body temperature (e.g. by using Paracetamol/Acetaminophen).
Please be aware of the active drugs in medicines that contain a combination of drugs. Further, the
presence or absence of a particular drug on this list do not preclude a certain harmful or safe use of
that particular drug in this patient respectively.
