When an injunction is given, it can be enforced with equitable enforcement mechanisms such as contempt. It can also be modified or dissolved (upon a proper motion to the court) if circumstances change in the future. These features of the injunction allow a court granting one to manage the behavior of the parties. That is the most important distinction between the injunction and another non-monetary remedy in American law, the declaratory judgment. Another way these two remedies are distinguished is that the declaratory judgment is sometimes available at an earlier point in a dispute than the injunction.
