Can gray stool be caused by lomotil?

Yes, gray stool can be caused by Lomotil (diphenoxylate and atropine), as this medication works by slowing down gut movement, which can affect bile production and lead to changes in stool color. Additionally, gray stool may indicate a lack of bile, which can occur with certain medications or gastrointestinal issues. If gray stool persists or is accompanied by other symptoms, it's important to consult a healthcare professional.
