Common medicines for colds can make you feel sleepy. True or False?

The correct answer is true because many over-the-counter medications used to treat colds contain antihistamines, which are known for their sedative effects. These medications can block histamine in the body, which may help alleviate symptoms like sneezing and runny nose, but they also often lead to drowsiness or sleepiness as a side effect. This is particularly important for individuals who may be driving or operating heavy machinery, as impaired alertness could pose safety risks. Understanding this effect is crucial for anyone who is using these medications, especially truck drivers, to ensure they remain safe and alert while on the road.
