The drugs are then carried in the blood to other parts of the body and may cause effects far from the eye. When administering the drops into the pouch formed with the lower eyelid, it is important to realize that this small space will only hold one drop. More than one drop usually overflows into the tear ducts or runs down the patient's face, wasting medication or exposing the patient to potential side effects. Even though it may be a hassle, if more than one drop of a drug is prescribed, the patient should administer it one drop at a time, then wait 5 to 10 minutes before administering the second drop. Likewise, if more than one type of eyedrop is prescribed, they should be administered at least 10 minutes apart.
Eye drops are one of the few ways where drugs can be administered close to the site of action.
Following these simple instructions will give you the maximum benefit from your eye drops.
