- Reduces salivation and excessive secretions of the respiratory tract
- Antidote for organophosphate or carbamate poisoning
|
Dose: |
For Treatment of Bradycardia
IV Direct
- 0.5-1mg q3-5min until desired rate achieved
IM/SC
Intratracheal
When used as a cholinergic antidote may require larger and more frequent doses. See PDAM for other indications
