Briviact, as a novel antiepileptic drug, has a relatively mild and mostly controllable spectrum of side effects. The following systematically elaborates on the characteristics of its side effects from three dimensions: common adverse reactions, special risk warnings, and life management recommendations.

1 Common adverse reactions

(1) Neurological symptoms: About 16% of patients experience drowsiness, 10% report dizziness, and most occur within the first 2 weeks of medication.

(2) Gastrointestinal reactions: Nausea incidence is 11%, vomiting is 6%, and taking medication after meals can reduce the risk by 40%.

(3) Psychological symptoms: emotional fluctuations such as irritability (7%) and insomnia (5%), which usually resolve on their own within one month.

2 Serious reactions that require vigilance

(1) Suicide risk: 0.4% of patients experience suicidal thoughts and require regular psychological assessment.

(2) Allergic reactions: The incidence of rash is 2%, and if vascular edema occurs, the medication should be stopped immediately.

(3) Abnormal liver function: The incidence of elevated ALT is 3%, and baseline examination is required before treatment.

3 Driving Safety

(1) Avoid driving during the initial 2 weeks of medication and evaluate reaction ability after the drug concentration stabilizes.

(2) If symptoms of drowsiness or dizziness occur, the evaluation period should be extended until 72 hours after the symptoms disappear.

(3) Night driving requires extra caution as changes in lighting may exacerbate visual adaptation barriers.

4. Work adaptation

(1) Suggest starting from part-time work and gradually transitioning to full-time work.

(2) Positions that require high concentration of attention should undergo professional cognitive function assessment.

(3) Reasonably arrange rest intervals and take short breaks every 2 hours to reduce fatigue.

5 Special Precautions

(1) Avoid sudden discontinuation of medication and take medication at a fixed time every day to prevent fluctuations in blood drug concentration.

(2) Record the occurrence time and symptom characteristics of adverse reactions, and provide detailed logs during follow-up visits.

(3) Before combining other medications, it is necessary to consult a physician, especially CYP3A4 inducers.
