Dilation of pupil Atropine sulphate (Eye).Non-proprietary

How does it work?

Atropine belongs to the group of medicines called anti-muscarinics. Atropine blocks the receptors in the muscles of the eye (muscarinic receptors). These receptors are involved in controlling the pupil size and the shape of the lens.

By blocking these receptors, atropine produces dilatation of the pupil (mydriasis) and prevents the eye from accommodating for near vision (cycloplegia).

Atropine is given as eye drops to dilate the pupil and relax the lens so that eye examinations can be carried out thoroughly. It is often used to aid eye examinations in young children. It is also used to relax the muscles that inflame and over-contract in the eye in conditions such as uveitus.

Irises that are dark in colour require larger doses of eye drops as they do not dilate as easily in response to this medicine.

What is it used for?

  • Dilating the pupil to aid examination of the eye

  • Inflammation of the coloured part of the eye and the muscle that controls it (uveitis)

Warning!

  • Do not drive unless you can see clearly.

  • You should not wear soft contact lenses while you are using this medicine. This it because the medicine contains a preservative that can be absorbed by soft contact lenses and cause eye irritation.

Use with caution in

  • Elderly people

  • Increased pressure within the eye ball (raised intraocular pressure)

  • Infants under 3 months of age
