Trazodone also has anti-anxiety (anxiolytic) and sleep-inducing (hypnotic) effects. Its side-effect profile and potential toxicity are considerably different from those of the original antidepressants (., the monoamine oxidase inhibitors (MAOIs) and tricyclic antidepressants (TCAs)). Do not drink alcohol or use medicines that may cause drowsiness (eg, sleep aids, muscle relaxers) while you are using Generic Desyrel; it may add to their effects. Ask your pharmacist if you have questions about which medicines may cause drowsiness. Contact your doctor at once if new, worsened, or sudden symptoms such as depressed mood; anxious, restless, or irritable behavior; panic attacks; or any unusual change in mood or behavior occur. Contact the doctor right away if any signs of suicidal thoughts or actions occur. And while some of the insomnia drugs are classified by the FDA as controlled substances that require doctors and pharmacists to take additional steps before they're prescribed or dispensed; trazodone is not a controlled substance, so doctors can prescribe it without those constraints.
