Trazodone for sleep: is it effective?

Trazodone is not prescribed primarily for sleeping problems.

It was designed as an antidepressant to treat depression.

However, according to the American Addiction centers Trazodone as a sleep aid is used to treat issues with sleep at lower doses and it is safer for elderly individuals than other sleep aids. 

So what is it really to have a sleeping problem? Well, it depends.

If you occasionally have trouble sleeping it doesn’t necessarily mean you have a sleeping problem per se.

If it is a frequent and constant problem falling asleep or staying asleep that is now affecting your life, then it is necessary to find professional help. 

If you found this guide, it is likely that you are wondering if trazodone for sleep is the best option for you but, here are some things you might want to consider before going any further.

What is Trazodone?

Trazodone is considered an antidepressant drug that belongs to the group of Serotonin Reuptake Inhibitors or SSRIs.

It is used frequently as a treatment for depression. 

This drug was developed in Italy in the 1960s as antidepressant medication.

Initially, due to the side effects, this antidepressant wasn’t widely accepted in the medical community, however, it became recognized by many internists and clinicians because of the potential benefits of the drug, especially when administered at low doses.

Under the name trazodone (generic) in 1981, it was approved by the U.S Food and Drug Administration (FDA) under the brand name Desyrel.

Today, it is prescribed under the brand name Olepro to treat sleep disorders such as insomnia as well as anxiety disorder and unibipolar depression.

Is it safe to take trazodone for insomnia?

Trazodone is widely prescribed as a nighttime sleep aid for people with acute insomnia, even though it was originally designed to treat depression and anxiety disorders. 

Trazodone for sleep is prescribed off-label and it has been suggested to be prescribed at doses between 25 mg to 100 mg.

It acts as a serotonin antagonist and reuptake inhibitor which is believed to act on several receptors in the brain affecting the balance levels of serotonin.

How do I know if I have insomnia?

It is necessary to share the symptoms with your doctor so he/she can assess if it is really a sleeping disorder or if its a secondary symptom of another medical condition. 

However, if you are suffering from insomnia the common symptoms are having mood problems, feeling fatigued or “drained” most of the day and reduced performance in your daily life activities. 

There are two possibilities, either having acute insomnia, where you have problems falling asleep short term and it is related to your context.

Let’s say you have something really important at school or a big presentation at work and you feel so anxious you start having problems falling asleep but as soon as that exam or the presentation have passed then you get to sleep as normal.

The other possibility is having chronic insomnia, this is characterized mainly because opposite to acute insomnia, this goes long term at least three nights a week and lasts for a minimum of three months. 

Are there advantages of trazodone for sleep?

If you have tried already other types of therapy like cognitive behavioral therapy or even hypnosis then looking out for a drug that can help you recover those long lost nights seem to be the only option right now.

Well, there is actually scientific data backing up the effectiveness of trazodone for sleep. 

In a 2017 systematic review about trazodone for insomnia, evidence for the efficacy of trazodone for sleeping problems was demonstrated for primary and secondary insomnia, including for symptoms that are a result of depression and dementia when administered in low doses. 

Is trazodone different from other “sleeping pill” drugs?

The most commonly prescribed drugs as sleeping aids are Ambien, Sonata or Lunesta, but Trazodone differs from them in a few ways such as:

  • Ambien and Lunesta have the potential for misuse and abuse (dependence or addiction) so they are classified as controlled substances.
  • Trazodone is not considered to be an addictive substance, hence it is not a controlled substance so physicians aren’t limited in how many pills they can prescribe
  • Compared to other drugs it is an inexpensive generic drug covered by most insurance companies
  • Trazodone is not recommended to be taken by pregnant women or women who are breastfeeding.

Does trazodone cause sleepiness?

For many people, this drug has a sedative effect that causes a relaxing effect and can make you feel very sleepy.

In prescribing the drug for sleep disorders, physicians typically recommend taking a low dose at bedtime in order to limit the effects of drowsiness.

Still, some people report lingering effects, including sluggishness and feeling drained or low energy, particularly upon waking.

How does Trazodone work?

Trazodone is meant to restore the depleted chemicals in the brain (neurotransmitters).

One of the most important neurotransmitters is serotonin which when balanced, improves your mood, appetite, memory, sexual function and desire, energy levels, decreases anxiety and insomnia related to depression.

Researchers have found that depression is caused by an imbalance among the neurotransmitters acetylcholine, norepinephrine, dopamine, and serotonin.

It is believed that trazodone affects the brain’s neurotransmitters by inhibiting the uptake of serotonin by nerves and consequently, the increase of this neurotransmitter end up stimulating other nerves.

How quickly does it work?

Some people who use this drug for sleep disorders have indicated that they get to experience the sedative effect within 30 mins after the intake, but remember that every person can react differently to the drug.

People who take it as an antidepressant may start noticing benefits after 1 or 2 weeks of consistently taking the medicine, and it may even take up to 4 weeks to experience the full benefits and desired results.
