Is it true that common medicines for colds can make you sleepy?

• A. True
• B. False
• C. Only in high doses
• D. Only if mixed with alcohol

Answer: (A)

Common medicines for colds often contain antihistamines, which are known to have sedative effects. These substances can inhibit the activity of certain neurotransmitters in the brain, leading to drowsiness. This is particularly true for first-generation antihistamines, such as diphenhydramine, which are frequently included in over-the-counter cold medications. While some people might experience different reactions to medications, the general effect of many cold medicines is to cause drowsiness. Additionally, other ingredients, such as certain pain relievers or cough suppressants, might also contribute to a feeling of sleepiness. Therefore, the statement is accurate, as many common cold medicines can indeed make a person feel sleepy.
