Trazodone and amitriptyline are two drugs that are often prescribed to treat depression and sleep disorders. While both drugs have been used to treat these conditions for decades, they work in different ways and have different side effects. Trazodone is an antidepressant that primarily targets serotonin receptors, while amitriptyline, also an antidepressant, increases the levels of serotonin and norepinephrine in the brain. This paragraph will explore the differences between these two drugs and discuss which may be better for sleep.

Trazodone is commonly used to treat insomnia, but it is not recommended as a first-line medication
Trazodone is an antidepressant sold under multiple brand names, including Desyrel. It is classified as a serotonin antagonist and reuptake inhibitor (SARI) and works by increasing serotonin levels in the brain. It is commonly used to treat insomnia, particularly when it coexists with anxiety or depression. However, it is not recommended as a first-line medication for insomnia treatment.
Trazodone is one of the most commonly prescribed medications for insomnia. It is often chosen over multi-action drugs like Elavil (amitriptyline) when patients experience difficulty sleeping or cannot tolerate other antidepressants. Trazodone's sleep-promoting effects are thought to be mediated by its antihistaminergic properties, which counter the alerting effects of histamine that increase as the morning approaches.
Despite its common use, trazodone is not recommended as a first-line medication for insomnia. This is because it is being used off-label, meaning it does not have FDA-approved indications for insomnia therapy. Limited data exist characterizing its efficacy and side-effect profile in the treatment of insomnia. While trazodone has been found to increase sleep time and improve sleep quality, its side effects may include daytime sedation, dizziness, and orthostatic hypotension.
Amitriptyline, on the other hand, is a tricyclic antidepressant (TCA) that is also sometimes used off-label for the treatment of insomnia. It has sedative effects, which may improve sleep latency and sleep maintenance. However, it is not recommended for insomnia treatment by insomnia guidelines, and it has more side effects than trazodone, such as sleepiness, weight gain, urinary retention, constipation, dry mouth, blurred vision, and orthostatic hypotension.
In summary, while trazodone is commonly used to treat insomnia, particularly in patients with coexisting anxiety or depression, it is not recommended as a first-line medication due to its off-label use and limited data on its efficacy and side effects in treating insomnia. Amitriptyline is also sometimes used off-label for insomnia but is not recommended by insomnia treatment guidelines and has a higher number of side effects compared to trazodone.

Amitriptyline is also used off-label for insomnia, especially for patients with headache disorders
Amitriptyline is a tricyclic antidepressant that has been around since the 1960s. While its popularity in treating depression has declined over the years, it has become increasingly prescribed for the treatment of insomnia. In the UK, it is licensed as an antidepressant and is prescribed at higher doses for the treatment of depression and low mood (50mg-200mg per day) and at lower doses to treat pain and prevent migraines (10-75mg per day). The dosage for insomnia treatment is typically within the range of 10-25mg per day.
Amitriptyline has sedative effects, which may improve sleep latency and sleep maintenance. It has a long half-life and may also improve sleep indirectly by treating headache or mood disorders. The drug has been used off-label for the treatment of insomnia for many years, but data from large controlled trials are lacking, and insomnia treatment guidelines do not recommend its use. Anticholinergic and antihistaminic adverse effects (e.g., urinary retention, constipation, dry mouth, blurred vision, orthostatic hypotension) are common with amitriptyline. Amitriptyline also causes QT-interval prolongation and cardiac conduction delays. Chronic use of anticholinergic drugs has been associated with an increased risk of dementia and is not recommended for older patients.
Despite the lack of data and the potential side effects, amitriptyline remains highly prescribed by GPs as a safer alternative to traditional sleeping tablets. This is because traditional sleeping tablets come with the risk of developing tolerance or addiction. Additionally, amitriptyline is prescribed at lower doses for insomnia treatment than for antidepressant use and may be better tolerated.
Patient-reported outcomes support the clinical observations that low-dose amitriptyline improves sleep maintenance in the short term and that it is generally well tolerated. This further justifies randomized controlled trials in patients with insomnia disorder and sleep maintenance problems to assess the effectiveness and safety of low-dose amitriptyline in the short and long term.

Trazodone primarily targets serotonin receptors, while amitriptyline acts on multiple neurotransmitters
Trazodone is a serotonin uptake inhibitor used to treat major depressive disorder. It is also used off-label for patients with insomnia. Trazodone inhibits the reuptake of serotonin and blocks the histamine and α-1-adrenergic receptors. It also induces significant changes in 5-HT presynaptic receptor adrenoreceptors. The drug's mechanism of action is not fully understood, which explains its off-label uses. Trazodone is well-tolerated and has better tolerability than second-generation SSRIs, which are associated with insomnia, anxiety, and sexual dysfunction.
On the other hand, amitriptyline acts on multiple neurotransmitters. It is a tricyclic antidepressant (TCA) that blocks the reuptake of serotonin and norepinephrine neurotransmitters. Amitriptyline is also a potent inhibitor of the serotonin 5-HT2A, 5-HT2C, the α1A-adrenergic, the histamine H1, and the M1-M5 muscarinic acetylcholine receptors. It is an FDA-approved medication to treat depression in adults. Amitriptyline is also used off-label for anxiety, post-traumatic stress disorder, insomnia, chronic pain, irritable bowel syndrome, and migraine prophylaxis, among others.
While trazodone primarily targets serotonin receptors, amitriptyline acts on multiple neurotransmitters, including serotonin and norepinephrine. Both drugs are used to treat depression, and both have off-label uses for treating insomnia. Trazodone's mechanism of action is not fully understood, whereas amitriptyline's antidepressant activity is believed to be due to the inhibition of serotonin and norepinephrine reuptake, which prolongs the activity of serotonergic and adrenergic neurons.
In terms of their effects on sleep, trazodone is specifically known for its ability to reduce nightmares and improve sleep habits in patients with PTSD. It exerts a sedative effect on sleep through the antagonism of specific receptors. Amitriptyline, on the other hand, is recommended for fibromyalgia accompanied by depression, and it has been shown to moderately improve sleep disturbances in this context.
Both drugs have their unique mechanisms of action and off-label uses, but it is important to note that the choice between the two for treating sleep disorders or depression should be made by a medical professional based on individual patient needs and considerations.

Trazodone is less likely to cause side effects like high blood pressure or heart rate
Trazodone is an antidepressant that is commonly used to treat insomnia and other sleep disorders, especially when they coexist with anxiety or depression. It is one of the most prescribed treatments for chronic insomnia. Trazodone primarily targets serotonin receptors, increasing serotonin levels in the brain and blocking its reabsorption. Unlike Elavil (also known as amitriptyline), which acts on multiple neurotransmitters, including norepinephrine, trazodone's mechanism of action makes it less likely to cause certain side effects linked to increased norepinephrine, such as high blood pressure or heart rate.
Amitriptyline is a tricyclic antidepressant that has been used off-label for the treatment of insomnia for many years, particularly for patients with headache disorders. It increases the levels of serotonin and norepinephrine in the brain, which are critical neurotransmitters that play a role in mood regulation, anxiety control, sleep patterns, and appetite. While amitriptyline has been found to improve sleep latency and sleep maintenance, it is not recommended by insomnia treatment guidelines due to a lack of data from large controlled trials.
The use of trazodone for sleep disorders is also considered off-label. However, it is commonly chosen over multi-action drugs like amitriptyline when patients have difficulty sleeping or cannot tolerate other antidepressants due to side effects. Amitriptyline is known to cause a variety of side effects, including weight gain, sexual dysfunction, sleepiness, and anticholinergic and antihistaminic adverse effects such as urinary retention, constipation, dry mouth, blurred vision, and orthostatic hypotension. While trazodone can also cause side effects, particularly at higher doses, it does not have the same common side effects associated with older types of antidepressants like amitriptyline.
In summary, trazodone's mechanism of action, which primarily targets serotonin receptors, makes it less likely to cause certain side effects linked to increased norepinephrine, such as high blood pressure or heart rate. While amitriptyline has been used for treating insomnia, it is not recommended by treatment guidelines due to a lack of data, and it has a higher risk of various side effects compared to trazodone. Therefore, trazodone may be a preferred choice for patients concerned about side effects or who have difficulty tolerating other antidepressants.

Amitriptyline is associated with more side effects, including sleepiness and weight gain
Trazodone and amitriptyline are both antidepressants that are also used to treat sleep disorders, particularly when insomnia coexists with anxiety or depression. Trazodone is one of the most commonly prescribed medications for insomnia. However, it is worth noting that it is often used off-label, and there is limited data to support its efficacy and side-effect profile in the treatment of insomnia.
Amitriptyline, on the other hand, is a tricyclic antidepressant (TCA) that has been used off-label for the treatment of insomnia for many years. While it has sedative effects that may improve sleep latency and sleep maintenance, it is associated with more side effects than trazodone. These side effects include anticholinergic and antihistaminic adverse effects, such as urinary retention, constipation, dry mouth, blurred vision, and orthostatic hypotension. Additionally, amitriptyline is known to cause weight gain and sleepiness, which are not common side effects of trazodone.
A study comparing the effects of trazodone and amitriptyline on geriatric subjects found that amitriptyline impaired vigilance and tracking performance and increased drowsiness. In contrast, trazodone only impaired the most difficult tracking task. This suggests that cognition and performance are less adversely affected in geriatric subjects by trazodone than by amitriptyline.
Furthermore, amitriptyline is not as commonly used today as other newer antidepressants due to its higher number of side effects. Trazodone, while also having more side effects at higher doses, is generally better tolerated by patients who have experienced adverse reactions from older types of antidepressants like amitriptyline.
In summary, while both trazodone and amitriptyline can be used to treat sleep disorders, amitriptyline is associated with more side effects, including sleepiness and weight gain. Trazodone may be a better option for patients who are concerned about these specific side effects or who have experienced adverse reactions to older types of antidepressants.
