BEWARE of TAMSULOSIN!
I have been taking it for years. When it came time to consider cataract surgery I discovered that tamsulosin can cause a condition called "floppy iris". That means you have to be sure to use a surgeon that knows how to handle that condition during surgery. If you look it up online you will see what can happen.
Unfortunately, even if you stop taking it, the risk remains for life.
May you trust in Jesus for your salvation. After all, life is a terminal condition.
