Yes I went thru the same thing with itchy skin and red welts on my check and back. Also my eyes had puss coming from
Them. I checked the ingredients of the lantanprost and discovered it has a Toxic preservative in it. It is. Called BAK! It’s Toxic! I stopped taking the drop and informed my doctor about what I found out also contacted Costco where I got the drug. The pharmacist wasn’t even aware of that toxic chemical being in latanoprost, but later came back and said I was right it is toxic. After taking myself off that drug my skin issues cleared up.
