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

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

Gentisyl NF 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.

Do not drive or operate machinery if vision is blurred.
