I found a pill in my husband's desk and wld like to know what it is. It appears to be old, as the imprint is barely visible, but it looks like there's either a symbol or maybe a lowercase cursive "a" on one side of the hash mark and "302" on the other side of the hash mark. I can't see any imprint on the other side of the pill, but being it's either old or has gotten wet, there may be one. It's about 15 mm long and it's a short, fat (or thick), white oblong pill. I've probably searched every drug imprint search engine online but no luck thus far. Can someone please help me identify this pill?
