Prozac (fluoxetine) is a widely prescribed antidepressant medication for humans. However, it is also commonly used off-label to treat various behavioral and emotional disorders in dogs.

Additional Side Effects

In addition to the common side effects listed above, some dogs may experience less frequent or more severe side effects, such as:
