This is an eye drop with cyclosporine used for treating dry eye. This medication improves both the quantity and quality of the tear film. Unfortunately, it can be expensive (this is getting better), stings going in, and takes a good month before improvement is seen. Also, it doesn’t work for everyone. On the other hand, most people with dry eye are desperate for relief so if the drop works, it is worth the hassle. If you develop an eye infection, temporarily stop this medication as it can make viral infections worse. This drop is usually dosed as a single drop twice a day.
