I by mistake putted mullein eye drops in my ear?

Usually ok: Eye drops are quite mild (non-irritating) because the eyes are so sensitive. Therefore, a few eye-drops accidentally placed into the ears will usually cause no problems. If problems do occur, one can call his primary care doctor for help.

Should be OK: Don't know what those drops are, but unless you have a hole in your ear drum, most eye groups won't hurt your ears.
