With any eyedrop you use, it is always recommended that you do the punctal occlusion.
Some patient information leaflets mention this while others don't. But even if it is not mentioned, we always recommend you do this with any prescribed glaucoma eyedrops.
It will help to stop side effects and is simple to do.
Make sure your hands have been washed.
Once you've put your eyedrops in, close your eye and gently press on the tear duct for up to 2 minutes. This will hold the drop in the eye and also stop it from entering your tearduct, getting to the back of the throat and into the bloodstream encouraging side effects.
You may do this already but if you don't, it is worth starting.
