Primary Issue
Major contradictions with label-listed oral tablet dosage form; multiple IV-only/oral-nonexistence claims conflict with the provided FDA label text.
Suggested Improvement
Remove/replace all claims that deny the existence/approval of oral tablets or that state Sivextro is only available as IV; align formulation statements to label section 3 DOSAGE FORMS AND STRENGTHS.
