Benadryl, an antihistamine containing diphenhydramine, can cause paradoxical reactions in some individuals, particularly children or the elderly, leading to increased agitation or restlessness instead of sedation. This is thought to be due to its action on the central nervous system, where it can block certain neurotransmitters. Additionally, the stimulating effects may be more pronounced in sensitive individuals or those with specific medical conditions. Always consult a healthcare professional if unexpected reactions occur.
