Although it is not addictive, your body does adjust to trazodone and you may experience withdrawal symptoms if you stop taking it. This is more likely if you have been taking trazodone for a long time and if you stop suddenly rather than slowly reducing the dosage. Withdrawal symptoms can include anxiety, irritability, nausea, restlessness, and trouble sleeping, among others. You should take trazodone as prescribed by your doctor. If you wish to stop taking the medication or change your treatment, you should always discuss the safest way of doing so with your doctor in order to mitigate the risk of withdrawal symptoms.
