Common medicines for colds can lead to drowsiness. True or False?

The statement is true because many over-the-counter cold medications contain ingredients such as antihistamines, which are known to cause drowsiness as a side effect. These medications work by blocking histamine in the body, which can alleviate symptoms like a runny nose and sneezing, but can also have a sedative effect. As a result, individuals taking these types of medication may experience increased drowsiness, making it important to be cautious, especially when operating vehicles or machinery. While some medications may have varying effects on different individuals, the general effect of common cold medications leading to drowsiness applies broadly to many people.
