Wut pill is white and says p251 on one side and nothing on the other side? And what pill is green and has a v on one side and 5688 on the other side

Not Medical Advice: Pill imprint P251 is Hyoscyamine sulfate ER 0.375 mg and used in the treatment of irritable bowel syndrome. Pill 5688 V is Risperidone MORE?
