Questions & Answers

Side Effects & Adverse Reactions

Addiction does not occur, although vomiting, malaise, sweating and salivation have been reported in patients with parkinsonism upon sudden withdrawal of large doses of scopolamine.  Scopolamine is one of the most important drugs of the belladonna group from the standpoint of poisoning; infants and young children are especially susceptible to the belladonna alkaloids.  Scopolamine is usually stated more toxic than atropine.  Idiosyncrasy is more common with scopolamine than with atropine and ordinary therapeutic doses sometimes cause alarming reactions.

Scopolamine Hydrobromide Injection, USP is indicated as a sedative and tranquilizing depressant to the central nervous system.  In its peripheral actions, scopolamine differs from atropine in that it is a stronger blocking agent for the iris, ciliary body and salivary, bronchial and sweat glands but is weaker in its action on the heart (in which it is incapable of exerting actions in tolerated doses), the intestinal tract and bronchial musculature.

In addition to the usual uses for antimuscarinic drugs, scopolamine is employed for its central depressant actions as a sedative.  Frequently it is given as a preanesthetic medicament for both its sedative-tranquilizing and antisecretory actions.  It is an effective antiemetic.  It is used in maniacal states, in delirium tremens and in obstetrics.  As a mydriatic and cycloplegic, it has a somewhat shorter duration (3 to 7 days) and intraocular pressure is affected less markedly than with atropine.


There is currently no drug history available for this drug.
