Ketotifen 0.025% (0.035%) Ophthalmic Solution: My Experience and Concerns About Side Effects

I've been using Ketotifen 0.025% (0.035%) Ophthalmic Solution for a few weeks now to deal with my seasonal allergies, and while it has helped with the itching, I can't shake off the worry about potential side effects. The list of urgent side effects is quite alarming, and I'm not sure what to do if I experience any of them. Has anyone else had any bad reactions to this drug? I've read that eye redness is common, but what about more serious issues? I'm also curious about the long-term effects of using this eye drop. I've been considering switching back to regular antihistamines, but I'm not sure if that would be a good idea. Has anyone tried both and can share their experience? Also, how do you report side effects to the FDA?
