Baclofen is a muscle relaxant that is commonly used to treat spasticity, particularly in conditions such as multiple sclerosis and spinal cord injury. One of the well-known side effects of baclofen is sedation. This occurs because baclofen acts on the central nervous system (CNS) to exert its muscle-relaxing effects, which can also lead to drowsiness and decreased alertness. As a result, patients taking baclofen may experience feelings of fatigue or sleepiness, making sedation a significant consideration in its use, especially when activities requiring full concentration are undertaken.

The other options listed, while they could potentially occur with various medications, are not widely recognized side effects of baclofen in clinical practice. Increased appetite, headache, and blurred vision are not typical reactions associated with baclofen and would be less expected compared to sedation. Thus, sedation stands out as the most common and clinically significant side effect of this medication.
