The health care provider will measure and monitor your vital signs, including temperature, pulse, breathing rate, and blood pressure. Symptoms will be treated as appropriate. You may receive:

• Activated charcoal
• Artificial respiration
• Fluids
• Laxative
• Medicine to lower acetaminophen levels in the blood (N-acetylcysteine)
• Medicine to reverse the effect of the hydrocodone (narcotic antagonist)

How well you do depends on the amount of poison swallowed and how quickly treatment is received. The faster you get medical help, the better the chance for recovery.

If you can receive medicines to reverse the overdose, you may get better within 1 - 4 days.
