Which medication is commonly associated with heat-sensitizing effects?

• A. Tylenol
• B. Sudafed
• C. Aspirin
• D. Ibuprofen

Answer: (B)

Medicines can change how the body regulates heat, and some drugs make you more prone to overheating during activity or in hot environments. Pseudoephedrine, the decongestant in Sudafed, is a sympathetic stimulant that can raise metabolic rate and narrow blood vessels, which can impair the body's ability to dissipate heat and increase core temperature. That connection to increased heat sensitivity is why Sudafed is the best choice here. The other options—acetaminophen, aspirin, and ibuprofen—are fever reducers or anti-inflammatories and do not typically increase heat sensitivity; they may help with fever rather than contribute to overheating.
