I’m discovering some very interesting products in our house while dealing with my aforementioned illness.
Nyquill that expired in 2010
Dayquill that expired in August (nearly new!)
This Sudafed expired in 2008
Afrin that expired in March
and this stuff, that doesn't have an expiration date but due to the discoloration of the label, it may be as old as I am.
And that's all we've got.
This isn't a new problem in our house, when I got my wisdom teeth out when I was in college my mom gave me some clove oil which is supposed to help with tooth-related pain. It had expired 2 years before I was born. I passed.
