what is the main function of hydrocodone?

Hii everybody , what is the main function of hydrocodone and how it is used? What are its side effects?

Please remember that Do not use this medication if you are allergic to acetaminophen (Tylenol) or hydrocodone otherwise it can show harmful side effects.

The most common side effects of hydrocodone include:

 Lightheadedness

Dizziness

Drowsiness

Nausea

Vomiting

Constipation 

Ive always heard of hydrocodone for severe pain relievers. Its a stronger version of all painkillers. The only times Ive used is for excruciating tooth aches for my wisdom tooth growing pains. It will def make you sleepy.
