PRECAUTIONS AND ADVERSE REACTIONS
BELLADONNA LEAF AND ROOT
General: No health hazards are known in conjunction with
the proper administration of designated therapeutic dosages.
The following could occur as side effects, particularly with
overdoses: erubescence, dryness of the mouth, mydriasis,
and tachycardiac arrhythmias. These are early signs of
atropine poisoning. Other side effects may include hypocyc-
loses, heat accumulation through reduction of perspiration,
micturation difficulties and obstipation. Because of potential
ramifications, Belladonna should be used only under the
supervision of an expert familiar with the appropriate use of
this substance.

Pediatric Use: The fatal dose in children is considerably less
than that of adults.
Drug Interactions: Tricyclic antidepressants, amantadine and
quinidine will increase the anticholinergic effect.
OVERDOSAGE
BELLADONNA LEAF AND ROOT
High dosages lead to central excitation that may produce
restlessness, compulsion to talk, hallucinations, delirium and
manic attacks, followed by exhaustion and sleep. The fatal
dose depends on me atropine content; asphyxiation can occur
with 100 mg atropine, which corresponds to 5 to 50 g of
Belladonna. Treatment of poisonings consists of gastric
lavage, application of wet cloths to reduce body temperature
(avoid antipyretics), oxygen respiration for breathing dis-
tress, intubation, parenteral physostigmine salts as an anti-
dote, diazepam for spasm and chlorpromazine for serious
excitation. (Also see side effects listed under PRECAU-
TIONS AND ADVERSE REACTIONS, which may be early
signs of poisoning.)
