Scopolamine (Scopolamine Hydrobromide) - Side Effects and Adverse Reactions

ADVERSE REACTIONS

With nearly all antimuscarinic drugs, dry mouth is the first and dry skin is the second most common side effect.  Thirst and difficulty in swallowing occur when the mouth and esophagus become sufficiently dry; chronic dry mouth also fosters dental caries.  Suppression of sweating causes reflexive flushing and heat intolerance and can result in heat exhaustion or heat stroke in a hot environment; it also contributes to the hyperthermia seen in intoxication.  Mydriasis frequently occurs, especially with scopolamine; photophobia and blurring of vision are consequences of mydriasis.  Cycloplegia (which exacerbates blurred vision) occurs approximately concomitantly with mydriasis, but usually higher doses are required.  In susceptible persons, especially the elderly, cycloplegia may contribute to an elevation of intraocular pressure.  Difficulty in urination and urinary retention may occur.  Tachycardia is a common side effect.  Constipation, even bowel stasis, may occur.

In the larger therapeutic doses, scopolamine may cause dizziness, restlessness, tremors, fatigue and locomotor difficulties.
