- Product / population
- Adults weighing at least 40 kg with acute uncomplicated influenza; oral baloxavir tablets. Pediatric and liquid formulations are outside this summary.
- Renal measure
- CrCl mL/min describes study evidence, not a severe-renal dose rule.
Labeled basic dosing
Give a single oral dose within 48 hours of symptom onset: 40 mg for weight 40 to less than 80 kg, or 80 mg for weight at least 80 kg.
Renal information and dialysis
No clinically meaningful pharmacokinetic difference was seen at CrCl 50 mL/min or greater. Severe-renal pharmacokinetics have not been evaluated; this label does not establish a numeric severe-renal or dialysis adjustment.
Selected warnings and limits
Avoid coadministration with dairy/calcium-fortified drinks and polyvalent-cation antacids, laxatives or supplements because absorption may fall.
