Homatropine, sold under the brand name Homatropaire among others, is a medication used to dilate the pupil as part of an eye exam or to help with the pain of anterior uveitis.[3][2] It is used as an eye drop.[3] Effects begin within 10 minutes and may last for up to 4 days.[2]

Common side effects include increased eye pressure, stinging, sensitivity to light, and dry mouth.[2] Other side effects may include delirium or agitation.[2] It is an anticholinergic.[2]

Homatropine was first made in 1883 or 1884.[4][5] It is available as a generic medication.[1] It is on the World Health Organization's List of Essential Medicines as an alternative to atropine.[6] In the United States a 5 ml bottle costs about 40 USD as of 2021.[7] It is made from atropine.[1]
