Generic Name: Istalol ()

Istalol Reviews

For Glaucoma, Open Angle "This has been the best medication for my glaucoma. Stings a little, but has controlled my pressures. I have not been able to use any of the drops such as Alphagan, Xalatan, etc., as I have an adverse reaction, i.e., migraine, drying and scratchy eye, very sensitive to light, etc."


For Glaucoma, Open Angle "This medication is excellent with no side effects for me, however the generic Timilol, does not work for near as well; Timilol has the same side effects as Xalatan and others that include headaches, migraines, dry eye, having to use twice as much, blurred vision. I do try new mediations as they come out but all of them have had the same side effects that are not acceptable, ie migraines and blurred vision, burning, itchy eyes.... Most all pharmacies and drug companies encourage generic, but I do not think it has the exact formula as the name brand; this includes Canadian drug companies and pharmacies."
