Analysis of possible health hazards caused by long-term use of Vigabatrin (Okeda)

Vigabatrin (Vigabatrin) is an anti-epileptic drug that mainly increases the level of GABA in the brain by irreversibly inhibiting γ-aminobutyric acid aminotransferase (GABA-T), thereby inhibiting abnormal neural discharges. It is commonly used to treat refractory partial epilepsy and infantile spasms. Although Vigabatrin is effective in controlling epileptic seizures, long-term use may bring certain health risks, especially the potential harm to the visual system and neurological function.

The most significant health risk of long-term use of Vigabatrin is retinal toxicity, which may result in permanent visual field loss. Studies have shown that some long-term users will develop peripheral visual field defects that are difficult to fully recover even after stopping the drug. Therefore, clinically, it is usually recommended that patients undergo basic vision and visual field examination before using Vigabatrin, and regular follow-up to monitor changes in visual field during treatment, so as to detect abnormalities early and adjust the medication regimen. Pediatric patients and infants need to be more cautious because their visual development is not fully mature and the risk may be higher.

Long-term use of Vigabatrin may affect central nervous system function, including cognitive ability, attention, and behavioral performance. Some patients experience decreased attention, learning ability, or mood swings during long-term treatment. Although such side effects may not necessarily pose a direct threat to life safety, they can affect the quality of daily life. Therefore, during long-term medication, family members and doctors need to closely observe changes in the patient's mental state and learning ability, and reduce risks by adjusting dosage or changing medications when necessary.

Vigabatrin may also have certain negative effects on other body systems, such as slight weight changes, drowsiness, or loss of coordination. Although most of these adverse effects are reversible, attention should be paid to long-term cumulative effects, especially in patients taking multiple antiepileptic drugs simultaneously. In short, the efficacy of Vigabatrin needs to be weighed against potential health risks. Patients should strictly follow the doctor's instructions when taking the medication, and undergo regular ophthalmological, neurological and systemic health examinations to ensure that long-term health risks are minimized while controlling epileptic seizures.
