Which class is known for side effects including blurred vision, dizziness, drowsiness, and rash, and is used to treat seizures?

• A. Anticonvulsants
• B. Antihypertensives
• C. Antidepressants
• D. Antidiabetics

Answer: (A)

Medicines that control abnormal brain activity to prevent seizures often cause central nervous system effects like drowsiness, dizziness, and sometimes blurred vision. They work by stabilizing neuronal membranes and reducing excessive electrical activity in the brain, typically through mechanisms such as blocking voltage-gated sodium channels or enhancing inhibitory neurotransmission. The sedating effect explains the common drowsiness and dizziness, while blurred vision can occur with CNS depression and changes in how the eyes coordinate with the brain. A rash is another known adverse reaction with this class, especially with drugs like carbamazepine and lamotrigine, which require monitoring for skin reactions. Because these drugs are specifically used to treat seizures, these side effects align with anticonvulsants.
