Amitriptyline and Remeron (Mirtazapine) are both antidepressants that are often prescribed off-label as sleep aids. While amitriptyline is a tricyclic antidepressant, mirtazapine is a tetracyclic antidepressant. Both drugs have sedative effects and are thought to improve sleep latency and sleep maintenance. However, it is important to note that there is limited scientific evidence supporting the use of these drugs for insomnia, and they are not licensed for this purpose. Additionally, amitriptyline has been associated with more adverse events and side effects compared to mirtazapine, particularly weight gain and anticholinergic and antihistaminic side effects.

What You'll Learn
Amitriptyline's effectiveness for sleep
Amitriptyline is a tricyclic antidepressant (TCA) that has been used to treat depression and approved by the Food and Drug Administration (FDA). It is also often prescribed for several other conditions like pain, migraines, and insomnia. It is available as a low-cost generic medication and is not habit-forming.
Amitriptyline is believed to work by increasing certain brain chemicals called neurotransmitters like serotonin and norepinephrine, which can help improve mood, sleep, pain, and anxiety. It also has a sedative effect, blocking histamine, which may result in drowsiness. This is one reason doctors prescribe amitriptyline as a sleep aid, typically at lower doses of 10-25mg per day for adults.
While amitriptyline is often prescribed as a sleep aid, there is limited scientific evidence supporting its efficacy for insomnia. It is often prescribed off-label for this purpose, and its effectiveness may be due to its ability to treat other conditions that may be causing sleep issues, such as pain, depression, or anxiety.
The DREAMING study is a large-scale, randomised, double-blind, placebo-controlled trial that aims to assess the effectiveness of low-dose amitriptyline (10-20mg/day) for insomnia in adults. This study will provide valuable insights into the effectiveness of amitriptyline specifically for insomnia and help inform clinical practice.
In summary, amitriptyline is often used as a sleep aid due to its sedative effects and ability to treat underlying conditions that may impact sleep. However, its effectiveness as a standalone treatment for insomnia is not yet fully supported by scientific evidence, and other treatments such as CBTi are recommended as the gold standard.

Remeron's side effects
Mirtazapine, sold under the brand name Remeron, is a prescription medicine used to treat depression. It belongs to a group of medicines called tetracyclic antidepressants, which work on the central nervous system to strengthen certain chemicals in the brain.
While mirtazapine is generally well-tolerated, it can cause side effects in some people. Serious side effects are rare, occurring in less than 1 in 10,000 people. However, it is important to be aware of the potential risks associated with taking this medication.
One of the most commonly reported side effects of mirtazapine is increased appetite and subsequent weight gain. This can be managed by maintaining a healthy, balanced diet, avoiding high-calorie snacks, and incorporating regular exercise into your routine.
Mirtazapine can also interact with alcohol and other central nervous system (CNS) depressants, such as antihistamines, sedatives, tranquilizers, and sleeping medications. It is important to consult your doctor before consuming alcohol or taking any other medications while on mirtazapine.
Additionally, mirtazapine may cause mood or mental changes, including abnormal thinking, agitation, anxiety, confusion, and feelings of detachment or excitement. It is recommended to speak to a doctor or pharmacist if these side effects persist or become bothersome.
In rare cases, mirtazapine has been associated with severe side effects such as stomach or back pain, nausea, headaches, confusion, weakness, muscle cramps, and yellowing of the eyes or skin, indicating potential liver problems. If you experience any of these symptoms, it is crucial to seek immediate medical attention.

Amitriptyline's side effects
Amitriptyline is a tricyclic antidepressant (TCA) that works by increasing certain brain chemicals called neurotransmitters like serotonin and norepinephrine to help improve mood, sleep, pain, and anxiety. It is approved by the Food and Drug Administration (FDA) to treat depression, but doctors also prescribe it to help with sleep.
When used as a sleep aid, amitriptyline is typically prescribed at lower doses, so side effects are generally minimal. However, there are still potential side effects to be aware of. The most common side effects of amitriptyline include:
- Drowsiness: Amitriptyline can cause drowsiness, so it is important to avoid driving or operating machinery until you know how this medication affects you. Alcohol can also add to the drowsiness caused by this drug.
- Weight gain: Weight gain is more frequent with amitriptyline compared to some other antidepressants, such as mirtazapine.
- Low blood pressure: Amitriptyline can reduce blood pressure when standing up.
- Urinary retention: This drug may cause trouble urinating, especially if there is a history of urinary retention.
- Liver problems: In rare cases, amitriptyline can cause liver problems, such as jaundice (yellowing of the skin or eyes). Elderly patients are more susceptible to this side effect.
- Allergic reaction: In rare cases, an allergic reaction (anaphylaxis) may occur, with symptoms such as swelling of the lips, mouth, throat, or tongue, breathing difficulties, and skin discolouration.
- Mental health changes: Amitriptyline may cause unexpected changes in mental health, including suicidal thoughts, especially at the beginning of treatment or when the dose is adjusted.
It is important to note that not everyone will experience these side effects, and many people may only have mild or no side effects at all. Additionally, some side effects may improve or go away as your body adjusts to the medication. If you experience any side effects, it is important to consult your doctor or healthcare provider for advice and guidance.

Amitriptyline's dosage for sleep
Amitriptyline is a prescription medication that is commonly used off-label to treat chronic insomnia. It is a tricyclic antidepressant that works by increasing certain brain chemicals called neurotransmitters like serotonin and norepinephrine to help improve mood, sleep, pain, and anxiety. It is available in tablet or liquid form with strengths ranging from 10 mg to 150 mg.
When used for sleep, amitriptyline is typically prescribed at lower doses than when used for the treatment of depression. The dosage for sleep usually starts at 10 mg and can be increased slowly until an effective dose is found. For adults, the dose typically ranges from 50 to 100 milligrams taken at bedtime, while adolescents and older adults may take lower dosages. It is recommended to take amitriptyline shortly before bedtime, but the timing can be adjusted by an hour or two if you find yourself waking up feeling groggy in the morning.
It is important to note that amitriptyline may not be the most effective treatment for insomnia. While it can aid in falling asleep due to its sedative effects, there is limited research on its direct impact on sleep. Additionally, it can reduce the amount of deep, slow-wave sleep, which is important for physical restoration and memory consolidation. Furthermore, amitriptyline may cause side effects such as constipation, dizziness, dry mouth, and drowsiness, and it may interact with other medications.
Before taking amitriptyline or any other medication for sleep, it is essential to consult with a healthcare professional to discuss your symptoms, medical history, and other relevant factors. They can provide personalized advice and determine the most suitable treatment option for your specific needs.

Remeron's dosage for sleep
Mirtazapine, also known by its brand name Remeron, is a medication used to treat major depressive disorder in adults. It is available in regular tablets and orally disintegrating tablets. The drug is also used to treat insomnia and suicidal ideation.
The recommended starting dosage of Remeron is 15 mg once daily, administered orally, preferably in the evening before sleep. If patients do not respond adequately to the initial 15 mg dose, it can be increased gradually every 1 to 2 weeks up to a maximum of 45 mg per day. The drug can cause drowsiness, so it is best taken at bedtime to avoid daytime sleepiness.
Remeron is generally well-tolerated, with a side-effect profile similar to that of a placebo. However, weight gain was reported more frequently with Remeron (13% of patients) compared to Amitriptyline (22% of patients).
Amitriptyline, on the other hand, is also a prescription drug available in different strengths and primarily used to treat depression. It is often prescribed for other conditions like pain, migraines, and insomnia. The dosage for treating insomnia typically ranges from 10 to 25 mg per day, with adults usually taking between 50 and 100 mg at bedtime.

Frequently asked questions
Amitriptyline is a prescription drug available in tablet form and approved to treat depression. It is also often prescribed for pain, migraines, and insomnia.
Remeron, or mirtazapine, is an antidepressant that has been prescribed off-label for insomnia for over a decade.
Both drugs are antidepressants that are prescribed off-label for insomnia. They are similar in that they both have sedative effects and may improve sleep latency and sleep maintenance.
There is limited data on the effectiveness of both drugs for insomnia. Some studies suggest that remeron may be more effective in reducing the risk of relapse and the recurrence of depression, which has an advantage over amitriptyline. However, amitriptyline is generally well-tolerated and may be a better option for those who also experience pain, as it can help reduce pain that may be keeping you awake.
Common side effects of amitriptyline include weight gain, sedation, anticholinergic and antihistaminic adverse effects (e.g. urinary retention, constipation, dry mouth, blurred vision, orthostatic hypotension), QT-interval prolongation, and cardiac conduction delays. Remeron has a similar side-effect profile to a placebo, with weight gain being the most frequently reported adverse event.
