Can taking one tablet of estazolam at night cause a change in stool color during the day?
Common formulations of estazolam include tablets, injections, etc. Under normal circumstances, taking one tablet of estazolam at night will not cause changes in stool color during the day. The detailed explanation is as follows:

Estazolam primarily acts on the central nervous system, producing sedative and hypnotic effects by regulating neurotransmitters. The drug is mainly metabolized in the liver and excreted through the kidneys, without generating metabolic byproducts that alter stool color. Changes in stool color are usually related to intestinal contents, drug pigments, or digestive system conditions. Since estazolam does not contain components that cause such effects, taking one tablet at night will not lead to changes in stool color the following day.
During treatment, it is important to take the medication on time and in the prescribed dosage, avoiding self-adjustment of dose or long-term continuous use. Maintain a regular sleep schedule, eat light and easily digestible meals for dinner, and reduce gastrointestinal burden. If abnormal stool color, abdominal pain, nausea, or other discomforts occur after taking the medication, promptly investigate possible digestive system issues, inform your doctor of the specific situation, so as to ensure the desired sedative and hypnotic effects while also addressing any physical abnormalities in a timely manner.
