For which finding should the nurse withhold lamotrigine and notify the provider? (Side effect)

• A. Double/blurred vision
• B. Dizziness
• C. Headache
• D. Nausea

Answer: (A)

Double or blurred vision signals a potential CNS adverse effect from lamotrigine that can worsen quickly and affect safety, especially during dose changes or if drug levels rise. Holding the dose and notifying the provider gives the clinician a chance to reassess the regimen, check for drug interactions (like valproate, which can increase lamotrigine levels), and decide whether to adjust the dose or pause the medication. Dizziness, headache, and nausea are common, milder side effects that are typically monitored or managed without stopping the drug.
