Need To Identify 3 Different Pills I Have : White

Need to identify 3 different pills i have : white round 93 over top of line on pill with 752 below the line. Next one is white oblong with 172 on one side and letter U on the other side. Next pill is oblong, white with the side of the pill split with a line between 19 and G. These are prescriptions I have that have fallen out of their bottles. I need to know what they are before I take them. Thank you for your time, Lynne Giuffre 435.513.2365
