It should not be used if the seal is broken, and contact lenses should be removed and re-inserted after 15 minutes. Common side effects include stinging, burning sensation, blurred vision, eyelid inflammation, and bitter taste. It should not be used if you have severe kidney problems, are allergic to sulphonamides, have liver problems, dry eyes, or cornea problems.
