A client receiving baclofen for muscle spasm reports drowsiness. This finding indicates what?

• A. Headache
• B. Nausea
• C. Drowsiness
• D. Diarrhea

Answer: (C)

Baclofen can cause central nervous system depression, so drowsiness is a common and expected adverse effect. This drug works as a GABA-B receptor agonist in the CNS, which reduces neuronal activity and can lead to sedation and fatigue. When a client reports being drowsy while using baclofen, it aligns with the drug’s known effect, highlighting the need for safety precautions such as avoiding driving or operating heavy machinery and limiting alcohol or other CNS depressants. If drowsiness is persistent or interfering with daily activities, a dose adjustment may be needed with the prescriber. While headache, nausea, or diarrhea can occur with various medications, they don’t match the symptom described in this case as closely as drowsiness does.
