Trimipramine and Doxepin are two medications that belong to the same class of drugs called tricyclic antidepressants (TCAs). These medications are both primarily used to treat depression but have different properties that make each drug unique.
Serotonin and norepinephrine are two important neurotransmitters, or chemical messengers, that are involved in several bodily functions, such as mood, appetite, sleep, and sex drive.
TCAs work by blocking the reuptake of serotonin and norepinephrine in the brain, which results in increased levels of these neurotransmitters and improvement in depressive symptoms.
Tricyclics are some of the oldest forms of medication used to treat depression, but they have been phased out in recent years in favor of other drugs, like SSRIs and SNRIs. Due to the way tricyclics work, they target other parts of the brain in addition to serotonin and norepinephrine. Because of this, they have a much larger side effect profile than selective drugs.
While tricyclics aren’t prescribed as often as they once were, they are still useful in certain patients, including those who feel that SSRIs and SNRIs are ineffective in treating their depression.
Tricyclic antidepressants, including Trimipramine and Doxepin, are used to treat depressive disorders, the most common of which is Major Depressive Disorder (MDD).
MDD is characterized by:
Trimipramine, sometimes called Surmontil, is a unique tricyclic medication. Thanks to its weak antipsychotic properties, it can be useful in treating depression with delusions or psychotic features.
The term off-label refers to any use of a medication that has not been FDA-approved, which requires a lengthy and extensive research process. Like most TCA medications, Trimipramine has sedative effects and is also useful in the treatment of insomnia and other sleep disorders.
Doxepin, also known as Silenor, is primarily used in the treatment of depression and anxiety. In 2010, 3mg and 6mg Doxepin tablets were FDA-approved for the treatment of insomnia.
Doxepin is also available as a topical cream to treat itching associated with certain dermatological conditions, such as eczema. Additionally, it is often prescribed off-label to treat diabetic neuropathy pain.
Doxepin, also known as Silenor in its brand-name form, is a tricyclic medication that is commonly used in the treatment of anxiety and depression. It is also commonly prescribed to treat primary insomnia, otherwise known as sleep onset insomnia, in which patients have difficulty falling asleep.
Doxepin is available in capsules, tablets, an oral solution, and topical creams. Doxepin capsules are available in a large range from 10 mg to 150 mg, while tablets are only available in 3 mg and 6 mg.
Doxepin is typically started at a low dose of 75 mg once daily and can then be titrated up weekly to a maximum dose of 150 mg per day.
There are several potential side effects associated with Doxepin, ranging in severity from mild to serious and even life-threatening. It is important to contact your healthcare provider or seek immediate medical attention if you begin to experience any of the serious side effects listed below.
Common side effects associated with Doxepin include:
Serious side effects of Doxepin include:
The majority of TCAs interact with several other commonly prescribed medications. As always, it is important to discuss all medications, including over-the-counter medications and supplements, with your healthcare provider before starting a new medication.
Common drug interactions with Doxepin include:
Doxepin is typically covered by most insurance plans and is a relatively affordable medication for those who are uninsured. The use of coupon codes that are found at large name-brand pharmacies can lower the cost of your 30-day supply from the average retail price of $50 to less than $10 per month.
Trimipramine, also known as Surmontil, is another tricyclic medication that is also commonly used to treat anxiety and depression. This medication is a unique TCA, as it has mild antipsychotic properties and can be used for the treatment of depression with psychotic features.
Trimipramine is available in 25 mg, 50 mg, and 100 mg capsules. The initial recommended dose is 25 mg at bedtime, but this can vary based on the severity of symptoms. For example, the starting dose in hospitalized patients can be as high as 100 mg but requires close monitoring.
The daily dose of Trimipramine can be slowly increased weekly with a maximum dose of 200 mg per day. This medication can be prescribed as a single dose at bedtime or divided into multiple doses throughout the day.
As with any medication, there are associated risks, such as side effects, that should be considered before starting a medication. The most common side effects associated with Trimipramine are mild, but there are a few serious adverse effects that require immediate medical attention.
The most common side effects of Trimipramine include:
Rare but serious side effects of Trimipramine that require immediate medical attention:
Like other tricyclic antidepressants, there are several drug interactions with Trimipramine. As always, you must disclose all current medications you are currently taking with your healthcare provider, including all over-the-counter medications and supplements.
The most common drug interactions with Trimipramine include:
Trimipramine, or name-brand Surmontil, is covered by the majority of health insurance plans, and coupon codes significantly reduce the cost of the medication for those who are uninsured. Coupons can be found at large retail pharmacies and lower the retail price down from $130 to $35 for a 30-day supply.
Yes. Like with all other antidepressant drugs, a prescription from a licensed healthcare provider is necessary for both Trimipramine and Doxepin. These medications are not available over the counter because, as described above, there are several drug interactions and side effects that need to be taken into account before starting a TCA medication.
A healthcare provider on Klarity can determine if a TCA medication, such as Trimipramine or Doxepin, is right for you.
There are a couple of uncommon but serious side effects that are associated with the use of tricyclic medications. It is important to be closely monitored when starting a TCA medication, and if you begin to experience any of the following adverse effects, contact your healthcare provider or seek out immediate medical attention.
Serotonin syndrome is a rare but serious and potentially life-threatening condition that occurs when there are high levels of serotonin in the body. This is most common in those who are taking multiple medications that increase serotonin levels.
Several medications cause serotonin levels to increase in the body, including other antidepressants, ADHD medicines, opioids, and non-prescription drugs like St. John’s Wort or MDMA.
The signs and symptoms of serotonin syndrome include:
Severe complications of serotonin syndrome:
It is important to seek immediate medical attention if you begin to experience these symptoms after starting a TCA medication, as this condition can be fatal if left untreated.
Tricyclics are generally avoided in pregnancy because of the following complications:
Taking a TCA medication while breastfeeding is typically viewed to be safe for the infant because there are relatively low levels of the drug within breast milk.
As with most antidepressant medications, there is a risk of worsening depression and suicidal ideation or self-harm behavior. This is a rare occurrence but is most commonly seen in those who are under the age of 24.

When comparing two medications from the same class of drugs, things can get confusing. We went over a lot of information, and it is common to have additional questions. Below we have answered some of the most frequently asked questions about Doxepin and Trimipramine:
No, although both Doxepin and Trimipramine belong to the same class of drugs called tricyclics, they are two separate medications, and each has unique properties.
Doxepin is considered to be an off-label treatment for anxiety because there are newer medications that are more effective in treating anxiety with fewer side effects.
There are several reasons one of these newer drugs may be ineffective for some, including drug interactions, certain health conditions, and the inability to tolerate the medication. In these cases, TCA medications like Doxepin remain to be a good alternative when treating anxiety. Your healthcare provider will help determine which anti-anxiety medication is best for you.
Doxepin appears to be a better choice for the treatment of anxiety over Trimipramine, but it is also important to note that this is still considered off-label use for the medication.
Although both medications are used to treat depression, Trimipramine is slightly more effective than Doxepin and can be used for more serious forms of depression due to its mild antipsychotic effects.
Driving or operating heavy machinery should generally be avoided when initially starting any TCA medication because of the potential to cause sedative effects.
You should avoid drinking alcohol while taking any TCA medication, including Doxepin or Trimipramine, because of an increased risk of adverse effects. Drinking alcohol and TCA medications both cause sedation and can be dangerous when taken together.
Due to the sedating effects of TCA medications, Doxepin and Trimipramine are typically prescribed to be taken at night before bedtime. Your healthcare provider will instruct you on how to take your medication, and it is important to follow these instructions.
