Health Canada has issued an advisory about an eye solution that may harm people using it.

It says consumers should not use Sandoz Timolol Ophthalmic Solution 0.25 per cent and 0.5 per cent, which is used to treat high fluid pressure within the eye and glaucoma, an eye disease that can lead to blindness.

Possible "adverse events" listed include:

* red eye
* eye irritation
