Tinnitus and hyperacusis are signs of an overdose on which substance?

Acetaminophen
Acetylsalicylic Acid (Aspirin)
Ibuprofen
Codeine

The correct answer is: Acetylsalicylic Acid (Aspirin)

Tinnitus and hyperacusis are associated with aspirin overdose, also known as acetylsalicylic acid. Aspirin belongs to the salicylate class of medications, and an overdose can lead to a range of symptoms, including auditory disturbances such as ringing in the ears (tinnitus) and increased sensitivity to sound (hyperacusis). These symptoms occur because aspirin affects the central nervous system and can alter the way the auditory system processes sound. In cases of toxicity, the more severe disturbances may also correlate with the body’s response to elevated salicylate levels, which can result in metabolic acidosis and other complications, sometimes leading to further neurological issues. Understanding the specific effects of various drugs is essential for emergency responders when assessing potential overdoses.
