Choose a source to jump directly to its locally stored result. Qualitative precautions and evidence gaps remain visible even when no numerical clearance schedule is supplied.

Read 1 source difference / applicability notes

Source presence is not independent validation. A label mirror is not a second independent source; review the original reference and exact formulation.

Independent clinical review is pending. These selected summaries are not an approved institutional dosing protocol. Confirm the exact product, the complete current source and local policy before use.

No dialysis or renal heading shown? Read the complete source summary. Absence of a heading is not evidence that dose adjustment is unnecessary.

Original GlobalRPh protocol

Clinical facts and comments transcribed into a structured reading format. Read the original source for its complete context: https://globalrph.com/renal/vigabatrin/

Indication and usual adult dosing

Original SABRIL indication: adjunctive refractory complex partial seizures after inadequate response to several alternatives, when benefit outweighs vision-loss risk; not first-line treatment.

500 mg tablets orally twice daily with or without food. Start 500 mg twice daily (1 g/day); increase total daily dose by 500 mg weekly according to response. Recommended adult dose 1.5 g twice daily (3 g/day). Six g/day had no additional benefit and more adverse events.

Withdraw gradually. The source adult trials tapered the total daily dose by 1 g at weekly intervals until discontinuation.

Renal Dosing

Primarily renal elimination. Original CrCl bands: above 50-80 mL/min, reduce dose 25%; above 30-50, reduce 50%; above 10 to under 30, reduce 75%. The wording leaves exactly 30 unassigned.

Cockcroft-Gault estimate: (140 - age) x weight in kg / (72 x serum creatinine in mg/dL), multiplied by 0.85 for females.

Import versus clinical validation
Source-section locators identify where retained content came from. A source-section identifier does not assert that every numeric statement has been independently corroborated. The local text hash is not a hash of original HTML, an FDA PDF or SPL XML.

The original individual GlobalRPh pages commonly cite NIH/NLM DailyMed and instruct readers to review the applicable package insert for updates. That historical reference is preserved as context; it is not counted as an independently retrieved current label.
