This product should not be used prior to peripheral iridectomy in eyes susceptible to angle closure because mydriatic action may precipitate angle block.

4.4 Special warnings and precautions for use

Murine should not be used if there is an eye condition characterised by continued redness, pain or blurring of vision.

Murine should not be used if there is raised pressure inside the eyeball (glaucoma), damage to the corneas, inflammation of the iris (acute iritis) or any other serious eye disease.

If there is any eye pain, vision changes, continued redness or irritation of the eye, or if the condition worsens or persists for more than 24 hours, use of the product should be discontinued and the doctor or pharmacist should be informed.

Discontinue use prior to use of anaesthetics which sensitise the myocardium to sympathomimetics (e.g. cyclopropane, halothane).

As with other sympathomimetics, use with caution in the presence of hypertension, diabetes, hyperthyroidism, cardiovascular abnormalities and arteriosclerosis.

Contains benzalkonium chloride which may cause eye irritation. Avoid contact with soft contact lenses; remove contact lenses prior to application and wait at least 15 minutes before re-insertion; known to discolour soft contact lenses.

4.5 Interaction with other medicinal products and other forms of interaction

Currently there is no information regarding the use of Murine and the absorption of concomitant ocular products.
