Dropping drugs in liquid form into your eye is a relatively uncommon route of administration. Its effectiveness is not well known.
You may want to consider doing these things if you do decide to drop drugs into your eye:
Don’t put solid drugs into your eye.
Putting solids such as powders or crystals into the eye is very dangerous. This is very likely to cause a lot of discomfort and damage, such as scratches to the delicate membrane of your eye. If dropping liquid drugs into the eye, make sure that they do not contain anything that will burn such as alcohols or acids.
Use a dropper that allows you to control the dose.
It is easy when using a dropper to accidentally put too much of the drug in your eye. Choose a dropper that can deliver a precise amount. It is a good idea to know how much of a drug you expect to be in one ‘drop’ so you can make sure you aren’t using more than you planned to.
Don’t drop drugs onto contact lenses.
Ensure you remove contacts before dropping any drug into your eye. Contacts can trap the drug in the eye and make it harder to flush your eye if you start experiencing discomfort.
Flush your eye after use.
It is especially important to do this if you experience any soreness, burning or discomfort. Use room temperature water in a clean bottle (such as a sterile water ampoule). Tilt your head to the side and lift the upper and lower eyelids away from the eyeball with clean fingers. Pour the water continuously, letting it flow over the eye. If your eye is painful or burning, continue flushing for at least 15 minutes. See a health professional if any discomfort persists or if you develop vision problems.
Take long breaks between use, and get help if discomfort persists.
The eye is a very delicate area, and repeated use can cause damage or infection quite easily. If you are experiencing any discomfort, swelling, burning or changes in vision after dropping drugs into your eye, seek medical attention.
