Stabbed myself with used needle

[Blitzjg]

The risk for infection is probably pretty high from an intravenous stick given the uncleanliness of snakes. I work at a hospital though and if someone is stuck with a needle I think the only immediate reponses are tests for chronic viral infections such as HIV Hep B, etc. Since you dont have to worry about those I would just look out for symptoms and signs of infection at the site. If you notice any of those a doctor visit is necessary.

*Edit*
AFAIK at the hopsital, they do not do any proactive antibacterial treatment, so the key is just to identify any changes or symptoms, if nothing develops then you are probably fine.
