What is the main side effect of musculoskeletal drugs?

1. Increased energy

2. Drowsiness

3. Weight gain

4. Insomnia

The correct answer is: Drowsiness

The main side effect of musculoskeletal drugs, particularly those used to manage pain and inflammation (such as muscle relaxants and certain analgesics), is drowsiness. This occurs because many musculoskeletal medications have sedative effects on the central nervous system. Drowsiness can be particularly pronounced when these medications are first started or when the dosage is increased. Patients may experience drowsiness because these medications are often designed to reduce muscle tension and alleviate pain, leading to a calming effect that can promote sleepiness. It is essential for individuals taking these medications to be aware of the potential for drowsiness, especially when engaging in activities that require full alertness, such as driving or operating machinery. The absence of increased energy, significant weight gain, or insomnia as prominent side effects of musculoskeletal drugs further clarifies that drowsiness is indeed the most relevant side effect associated with this class of medications.
