    • For the treatment of aggression and restlessness in patients of dementia
    • Insomnia

Trazodone (Oleptro) Dose in Adults

Trazodone (Oleptro) Dose as an alternative agent in the treatment of Aggressive or agitated behavior associated with dementia (off-label): Oral:

  • Immediate release:
    • Initial: 25 to 50 mg OD at bedtime;
    • depending on reaction and tolerance, titrate up to 300 mg/day in 1 to 3 split doses.

  • Immediate release:
    • Usual dose: 50 mg to 100 mg at bedtime.
    • Note: may begin with 12.5 to 50 mg eg for patients on palliative care.
    • The dose may be up titrated up to 200 mg according to tolerance and response. (eg, in patients with drug abuse history)
    • In such patients, trazodone is more preferable because of decreased potential for dependence.

Trazodone (Oleptro) Dose in the treatment of insomnia in patients with depression (as an adjunct to other appropriate antidepressant treatment [eg SSRI]): Oral:

  • Immediate release:
    • Usual dose: 50 to 300 mg at bedtime.
    • May titrate up to 600 mg/day however no added benefit is established and there is an increased risk for toxicity.

Trazodone (Oleptro) Dose as an alternative agent in the treatment of major depressive disorder (unipolar): Oral:

  • Immediate-release:
    • Initial: 50 mg twice daily; can be up titrated by 50 mg/day every 3 to 7 days until total 75 to 150 mg BD.
    • usual dosage range 200 to 400 mg/day;
    • The maximum 600 mg/day.
    • However, increased potential for toxicity with a higher dose.
    • >400 mg/day is Contraindicated in patients with cardiovascular disease.
    • To avoid sedation, divide the daily dose and administer the smaller amount during the day and the bigger dose just before bed.
    • Manufacturer’s labeling:
      • Dosing in the prescribed material could not follow current clinical recommendations.
        • Initial: 150 mg/day in divided doses;
        • highest dosage: 400 mg per day; 600 mg per day (patients) (outpatients).

    • The maximum dose: 375 mg/day
  • Discontinuation of therapy:
    • To avoid withdrawal symptoms don't stop at once, down-titrate slowly over 2 to 4 weeks.
    • Resuming the previously prescribed dose or reducing the dose more gradually are the two options to consider if intolerable withdrawal symptoms develop after a dose reduction.
    • Tapering over more than three months may be beneficial for some individuals receiving long-term treatment (>6 months), such as those with a history of discontinuation syndrome.
    • Evidence supporting ideal taper rates is limited.
  • Switching antidepressants:
    • Limited data are available.
    • Consider the degree of symptom management desired, the risk of discontinuation symptoms, potential drug interactions, half-life, side effects, and pharmacodynamics.
    • Crose titration: while gradually increasing the new antidepressant, cease the previous antidepressant).
    • immediate switch (suddenly stop the first antidepressant and then start a new antidepressant at an equal or lower dose with slow up-titration).
    • Cross-titration is common for most switches but is not advised when transitioning to or from an MAOI (e.g., over 1 to 4 weeks depending on tolerance and withdrawal symptoms).
    • While switching drugs within the same or related classes (e.g., switching two SSRIs), when taking an antidepressant for less than a week, or when discontinuing because of side effects, a direct switch is preferred.
  • Switching to or from an MAOI:
    • Give a 14-day break between stopping an MAO inhibitor and starting trazodone, and the opposite is true.

Trazodone (Oleptro) Dose in Childrens  

Trazodone (Oleptro) Dose in the treatment of Insomnia; sleep disturbances (in children with comorbid psychiatric disorders):

There are few data on this, although it is often used clinically in kids with co-occurring psychiatric illnesses (eg, mood disorder, anxiety disorder, developmental delay with ADHD): Oral:

  • Immediate-release formulation:
    • Children 18 months to <3 years:
      • Initial: 25 mg/dose at bedtime; can be increased by 25mg every 2 weeks to a maximum dose: 100 mg/dose
    • Children 3 to 5 years:
      • Initial dose of 50 mg at bedtime; maximum dose of 150 mg, which can be increased by 25 mg every two weeks. Do not exceed 200 mg/day; the range is 0.5 to 2 mg/kg/day.
    • Children >5 years and Adolescents:
      • Initial: 0.75 to 1 mg/kg/dose or 25 to 50 mg at bedtime;
      • When used for palliative care, documented trials in young children with comorbid psychiatric illnesses (such as ADHD, autism, developmental delay), or sleep bruxism, multiple daily doses may be necessary; 25 to 50 mg/dose increase gradually to twice or three times daily as necessary (not to go beyond adult dose)

Trazodone (Oleptro) Dose in the prophylaxis of Migraine: 

  • Children and Adolescents ≥7 years: Oral:
    • Immediate-release formulation:
      • 1 mg/kg/day in 3 divided doses;
      • maximum dose: 150 mg/dose.

Discontinuation of therapy:

  • To avoid withdrawal symptoms do not stop at once, down titrate slowly.
  • No specific duration of taper established. According to the antidepressant's half-life, APA and NICE guidelines advise tapering therapy over at least a few weeks; antidepressants with a shorter half-life may require a slower taper.
  • WFSBP guidelines advise tapering over 4 to 6 months for those receiving long-term therapy.
  • If withdrawal symptoms appear, taper more gently, or stop using the drug if it is not tolerated.

MAO inhibitor recommendations:

Switching to or from an MAO inhibitor intended to treat psychiatric disorders:

  • Give a 14-day break before starting trazodone after stopping an MAO medication, and vice versa.

Trazodone (Oleptro) Use with other MAO inhibitors (linezolid or IV methylene blue):

  • Patients taking IV methylene blue or linezolid should not take it.
  • If linezolid or IV methylene blue use cannot be avoided in patients on trazodone, stop trazodone at once and administer linezolid or IV methylene blue.
  • Until 24 hours following the last dosage of linezolid or IV methylene blue, or for a period of two weeks, keep an eye out for serotonin syndrome. 24 hours after the last linezolid or IV methylene blue dosage, start taking trazodone again.

Trazodone Pregnancy Category: C

  • Multidisciplinary approach is required to treat depression during pregnancy.
  • This includes mental health professionals, primary care providers, and pediatricians.
  • The American Psychiatric Association advises that pregnant women carefully weigh the risks and benefits of using trazodone, or any other treatment for depression, during pregnancy.
  • Women at high risk of postpartum depression can start treatment after they have given up on medication during pregnancy.

Use of Trazodone while breastfeeding

  • Breast milk contains Trazodone.
  • If RID is less than 10%, lactation can be continued. Other studies suggest that a cutoff of RID of 5% should be used for psychotropic drugs.
  • The RID of Trazadone was calculated with a 100 ng/mL milk concentration, indicating a daily infant dose via breastmilk of 0.015 mg/day.
  • This was achieved by giving a single dose to six healthy breastfeeding women of trazodone 50mg.
  • There are not many studies on the effects of trazodone on lactating women.
  • Monitor breastfeeding mothers who use psychotropic drugs daily to alter their sleep, dietary habits, or behavioral changes.
  • Also monitor infants' growth and neurodevelopment.
  • Before starting trazodone, it is important to consider the risks and benefits. 
  • If there are no contraindications, breastfeeding mothers who have been successfully treated with trazodone in pregnancy will be able to continue taking it while they breastfeed.

Warnings and precautions

  • Bleeding Risk:
    • Serotonin reuptake inhibitors, such as SSRIs, have been related to bleeding.
    • This can range from minor bruising and epistaxis, to potentially fatal hemorhage.
    • In addition, the related drug trazodone may similarly hinder platelet aggregation, raising the risk of bleeding incidents.
  • Cardiac arrhythmias
    • There is a low risk of conduction abnormalities in antidepressants.
    • With immediate-release formulations, ventricular tachycardia and QT prolongation (with and without torsades-de-pointes) have been recorded.
    • If you have a history of cardiac illness, such as a MI, a stroke, or faulty conduction, use with caution.
    • It has also been reported that isolated PVCs, ventricular couplests and tachycardia have been reported.
    • CYP3A4 inhibitors can increase QT prolongation risk and other cardiac arrhythmias.
    • While recovering from acute recovery of MI, it is contraindicated.
  • Depression in the CNS:
    • CNS depression can lead to decreased mental alertness and CNS depression.
  • Fractures
    • An increase in bone fractures.
    • Antidepressant users who also have unexplained bone pain, point tenderness, or edoema may develop fragility fractures.
  • Ocular effects
    • In predisposed patients, narrow-angle glaucoma can occur.
    • Patients with narrow angle glaucoma risk factors who have not undergone iridectomy should be assessed.
  • Orthostatic hypotension, syncope
    • Orthostatic hypotension can lead to syncope (increased danger compared to other antidepressants); avoid these side effects if you have a high risk of developing them or if you are allergic to hypovolemia or any drugs that may cause hypotension or bradycardia.
  • Priapism
    • Rarely, a painful erection can last more than six hours.
    • For an erection lasting more than 4 hours, seek medical attention.
    • Be careful when using this product in situations that could also lead to priapism, such as multiple myeloma or sickle cell anemia.
  • Serotonin syndrome
    • When serotonergic drugs (such as SSRIs and SNRIs) are combined with other serotonergic drugs and substances that affect the metabolism of serotonin, such as triptans TCAs, fentanyl and buspirone, tramadol or buspirone, St. John's wort or tryptophan, serotonin syndrome (SS), a potentially fatal condition, may result (eg MAO inhibitors to treat psychiatric methylene blue, intravenous methyleneblue blue)
    • Be on the lookout for SS in patients, including mental changes (such as agitation, hallucinations, or coma), autonomic stability (such as tachycardias, labile pressure, diaphoresis), neuromuscular disorders (such as tremors, rigidity, and myoclonus), GI symptoms (such as nausea, vomiting, and diarrhoea), and/or seizures.
    • Stop using the product immediately if you notice any symptoms or signs.
  • Hyponatremia and SIADH
    • SSRIs have been linked to severe hyponatremia and SIADH in patients with diuretics or elderly who are dehydrated.
  • Hepatic impairment
    • Use caution in the presence of liver disease.
  • Hypomania/mania:
    • Some patients may experience psychosis.
    • Bipolar disorder can lead to hypomania and mania. Before you start treatment, make sure you rule out this condition.
    • Bipolar disorder is not a condition that can be treated with a single agent.
    • The FDA has not approved Trazodone for bipolar depression treatment.
  • Renal impairment
    • Avoid kidney disease.
  • Seizure disorder
    • Patients with seizure disorders, brain damage, brain trauma, alcoholism or any drugs that may lower the seizure threshold should be cautious.
