What is the exact meaning and scope of the word POISON enclosed in the red box on prescribed medicine?

Hello, snowboot.

Thank you for writing.

Position refers to any substance that can impair function, cause structural damage, or otherwise injure the body. A related word commonly seen is toxic. Even prescriptions drugs can cause harm if taken incorrectly, taken with other medications, drugs, or alcohol which may cause an interaction. Labels might vary in color for warnings, interactions and, side effects depending on the pharmaceutical. Generally, most are the same or similar.
