A client with spinal cord injury on baclofen shows which sign indicating a side effect?

• A. Drowsiness
• B. Nausea
• C. Hypertension
• D. Rash

Answer: (A)

Baclofen can cause central nervous system depression, which is why drowsiness is the most common sign of a side effect in a person with spinal cord injury. By activating GABA-B receptors in the spinal cord to reduce muscle spasm, it also dampens overall brain activity, leading to sleepiness and slowed alertness. This side effect is why clinicians watch for sedation and assess safety with activities requiring focus, especially when starting therapy or increasing the dose. Nausea can occur but is less characteristic, while hypertension is not typical for baclofen ( it more commonly isn’t associated with high blood pressure, and some patients may experience hypotension). Rash would suggest an allergic reaction rather than a common drug effect. If drowsiness is troublesome, dose timing or amount may be adjusted and other sedating meds reviewed.
