Mirtazapine is not addictive in the way Clonazepam can be, so you do not develop cravings or dependence on it. It is commonly used for depression and can also help improve sleep, especially at lower doses like 7.5 mg. However, like most antidepressants, it should not be stopped suddenly because you may feel temporary symptoms like sleep disturbance or irritability, so any dose changes should be done gradually under your doctor's guidance. Overall, it is considered safe for longer-term use when prescribed appropriately, and you can take it as advised without worrying about addiction.
