Which two medications are known to discolor urine to a pink or red color?

The selection of Thorazine and Dilantin as the answer is accurate because both of these medications are known to cause discoloration of urine to a pink or red hue.

Thorazine, an antipsychotic medication, can influence urine color due to its effects on the urinary tract and metabolism within the body, leading to changes in excretion. Dilantin, an anticonvulsant, may also impart a reddish tint to the urine as a result of its breakdown products and how it interacts with the body’s systems.

In contrast, the other medications listed do not have a well-documented side effect of causing urine to change color in this manner. Prozac and Zoloft are selective serotonin reuptake inhibitors (SSRIs) primarily affecting mood and behavior without significant impact on urine color. Ativan and Klonopin, which are benzodiazepines, generally do not lead to noticeable changes in urine appearance. Ritalin and Adderall, stimulant medications for ADHD, also do not cause discoloration of urine. Understanding the specific side effects associated with each of these medications can help in monitoring patients for potential reactions, such as unusual urine color changes.
