I have a bottle that came from the pharmacy with two kinds of pills. The label states that the pills (lisinopril - 10mg - Watson 407) are "small, round, blue tablet" - however the other pills are less than half the size, yellow and imprinted with a sole "A" on one side and the number "22" on the other. I cannot see how this tiny pill can be 10mg of anything, and I cannot find a pill that looks like this under lisinopril. Any help is appreciated.
