I, too, have the same question-can anyone help? half red, half yellow. on the red side, L 187 imprinted with a parallelogram, that is open by the 7, surrounding the L187. There is also a small segment pointing down and away from the parallelogram on the side with the 7 so that it also looks like the bottom of L 187 has an upside down square root around it and the top part has half a parallelogram around it.
This pill is ACETAMINOPHEN 500 MG
a generic version of Tylenol Extra Strength
Imprint Code L187
Description yellow/orange-red, round tablet
The imprint is on the yellow side - L187 in a sort of "speech bubble"
