What is the typical pupil response seen in narcotic overdoses?

In narcotic overdoses, the typical pupil response is constricted pupils, often referred to as "miosis." This physiological reaction occurs due to the action of opioids on the body, particularly their effect on the central nervous system. Opioids stimulate the parasympathetic nervous system, leading to the contraction of the muscles that control pupil size.

Constricted pupils can be a critical sign in medical assessments when determining possible substance overdoses. This symptom is especially significant because it helps differentiate narcotic overdoses from other types of drug overdoses, which may present with different pupil sizes, such as dilated pupils seen in stimulant overdoses.

Understanding this typical response is essential for healthcare professionals, as it guides appropriate interventions and treatments in emergency medical situations.
