Author Question: How Fast Does A Tranquilizer Dart Work?

Alyson Asks:

I’m writing a script where the villains shoot people with a gun but we discover later it was only a tranquilizer. Is there a tranquilizer drug combination that can be shot from a distance (can be close range) at a person that would take effect fairly immediately? Or would stop them from being able to communicate immediately.

Jordyn Says:

Thanks for sending me your question.

There is no drug combination given intramuscularly (IM or within the muscle as a dart injection would be) that would incapacitate a victim immediately or even within a few seconds. For instance, Ketamine takes 3-4 minutes to work IM. This will be the case with most drugs given via this route— the range of 2-4 minutes for onset of action.

Hope this answers your question.

Best of luck with your story.
