Antidepressants increased the risk compared to placebo of suicidal thinking and behavior in children, adolescents, and young adults with major depressive disorder (MDD) and other psychiatric disorders in short-term studies. Short-term studies did not show an increase in the risk of suicidality with antidepressants compared with placebo in adults beyond age 24, and there was a reduction in risk with antidepressants compared with placebo in adults aged 65 or older. The use of trazodone hydrochloride or any other antidepressant in a child, adolescent, or young adult must balance this risk with the clinical need. Closely monitor patients of all ages for clinical worsening, suicidality, or unusual changes in behavior. Families and caregivers should be advised of the need for close observation and communication with the prescriber. Not approved for pediatric use .

Before using Desyrel
In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For this medicine, the following should be considered:
Tell your doctor if you have ever had any unusual or allergic reaction to this medicine or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.
Appropriate studies have not been performed on the relationship of age to the effects of trazodone in the pediatric population. Safety and efficacy have not been established.
Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of trazodone extended-release tablets in the elderly. However, elderly patients are more likely to have hyponatremia (low sodium in the blood), which may require caution in patients receiving trazodone.
No information is available on the relationship of age to the effects of trazodone regular tablets in the elderly.

Precautions while using Desyrel
It is very important that your doctor check your progress at regular visits, to allow for changes in your dose and to help manage any unwanted effects.
Do not take trazodone with a monoamine oxidase (MAO) inhibitor (eg, isocarboxazid [Marplan®], linezolid (Zyvox®), methylene blue, phenelzine [Nardil®], selegiline [Eldepryl®], tranylcypromine [Parnate®]). Do not start taking trazodone during the 2 weeks after you stop a MAO inhibitor and wait 2 weeks after stopping trazodone before you start taking a MAO inhibitor. If you take them together or do not wait 2 weeks, you may develop confusion, agitation, restlessness, stomach or intestinal symptoms, a sudden high body temperature, an extremely high blood pressure, or severe convulsions.
Trazodone may cause a serious condition called serotonin syndrome if taken together with some medicines. Do not use trazodone with buspirone (Buspar®), fentanyl (Abstral®, Duragesic®), lithium (Eskalith®, Lithobid®), tryptophan, St. John's wort, or some pain or migraine medicines (eg, sumatriptan, tramadol, Frova®, Maxalt®, Relpax®, Zomig®).
For some teenagers and young adults, this medicine can increase thoughts of suicide. Tell your doctor right away if you start to feel more depressed or have thoughts about hurting yourself or others. Report any unusual thoughts or behaviors that trouble you, especially if they are new or get worse quickly. Make sure the doctor knows if you have trouble sleeping, get upset easily, have a big increase in energy, or start to act reckless. Also tell the doctor if you have sudden or strong feelings, such as feeling nervous, angry, restless, violent, or scared. Let the doctor know if you or anyone in your family have bipolar disorder (manic-depressive disorder) or have tried to commit suicide.
Check with your doctor right away if you have anxiety, restlessness, a fast heartbeat, fever, sweating, muscle spasms, twitching, nausea, vomiting, diarrhea, or see or hear things that are not there. These may be symptoms of serious conditions called serotonin syndrome and neuroleptic malignant syndrome-like reactions. Your risk may be higher if you also take certain other medicines that affect serotonin levels in your body.
Contact your doctor right away if you have any changes in your heart rhythm such as feeling dizzy or faint, or having a fast, pounding, or uneven heartbeat. These could be symptoms of a heart problem called QT prolongation.
Dizziness, lightheadedness, or fainting may occur, especially when you get up suddenly from a lying or sitting position. Getting up slowly may help. If this problem continues or gets worse, check with your doctor.
Do not stop taking this medicine without first checking with your doctor. Your doctor may want you to gradually reduce the amount you are using before stopping it completely. This may help prevent a worsening of your condition and reduce the possibility of withdrawal symptoms such as anxiety, irritability, restlessness, or trouble sleeping.
This medicine may cause some people to become drowsy or less alert than they are normally. Make sure you know how you react to this medicine before you drive, use machines, or do anything else that could be dangerous if you are not alert.
This medicine will add to the effects of alcohol and other CNS depressants (medicines that make you drowsy or less alert). Some examples of CNS depressants are antihistamines or medicine for allergies or colds, sedatives, tranquilizers or sleeping medicine, prescription pain medicine or narcotics, medicine for seizures or barbiturates, muscle relaxants, or anesthetics, including some dental anesthetics. Check with your doctor before taking any of the above while you are using this medicine.
Before having any kind of surgery, dental treatment, or emergency treatment, tell the medical doctor or dentist in charge that you are using this medicine. Taking trazodone together with anesthetic medicines (numbing medicines) that are used during surgery, dental treatments, or emergency treatments may cause an increase in CNS depressant effects.
Trazodone may cause dry mouth. For temporary relief, use sugarless gum or candy, melt bits of ice in your mouth, or use a saliva substitute. However, if your mouth continues to feel dry for more than 2 weeks, check with your medical doctor or dentist. Continuing dryness of the mouth may increase the chance of dental disease, including tooth decay, gum disease, and fungus infections.
Do not take other medicines unless they have been discussed with your doctor. This includes prescription or nonprescription (over-the-counter [OTC]) medicines and herbal or vitamin supplements.
