Drops with Epinephrine can cause redness of the eyes and pupillary dilation. They can also cause alterations in heart rate. Again, if you present any side effects upon using any type of drops for the eyes, suspend them immediately and communicate with your doctor. It is a common myth that all drops are the same and that they are just watery substances. This is not true at all.
Eye drops are powerful medications of varying degrees just like all other medicines.
Some are safe but others are dangerous medications. Some eye-drops can cause glaucoma or cataracts if misused. Many are harmless when used as directed, but very dangerous when the patient keeps on using them beyond the period prescribed by the doctor. Steroid drops are usually extremely potent and require the supervision of the eye care specialist. Using steroid drops, and indeed all other eyedrops that may have been previously prescribed for other conditions, or for other patients, can be a great mistake.
