Question: 1 / 400

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

True

The answer is true because many common cold medications contain ingredients such as antihistamines, which are known to have sedative effects. These sedative properties can lead to drowsiness, making the user feel sleepy after taking the medication. It's important for individuals to read the labels and instructions on over-the-counter cold medications, as some formulations specifically warn about potential drowsiness. Awareness of this effect is crucial, especially for those who need to operate vehicles or machinery, as impaired alertness can pose safety risks. While some medications might have different side effects or may not cause drowsiness at all, the general trend is that many cold medicines do indeed make users feel sleepy due to their active ingredients.
