Transdermal scopolamine (Hyoscine): visual side-effects

Aims: To highlight the side effects of transdermal scopolamine. Methods: Evidence from the literature is presented concerning the use of this drug and visual side effects. Results: The main side effects are pupillary dilation and blurring of vision. These appear to be more frequently encountered with repeated use of patches and where there is local contamination between the patch and the eye. Conclusions: Awareness of the visual side effects of transdermal scopolamine may help the clinician recognise symptomatic conditions presenting in adults; and especially in children with special needs who are unable to communicate problems.
