- Intravenous Tylenol currently is many times more expensive than oral
- Single ED study comparing the two has methodology flaws and there is a lack of additional evidence to support intravenous over oral formulations solely for pain control
- Oral Tylenol appears to be at least equally efficacious, though with a slightly slower onset of action
