| Meta Canonical | null |
| Boilerpipe Text | Combination drug therapy is a type of treatment that many doctors and psychiatrists have been increasingly using during the past decade.
Until recently, doctors prescribed an
antidepressant
medication from only a single class of drugs, one medication at a time, called monotherapy.
Doctors generally start at a lower dosage and increase it before ruling it out as ineffective. If that happens, they might try another medication within that class or switch to another class of antidepressants entirely.
Research from 2022
now suggests that taking a combination of a specific class of antidepressants that includes mianserin,
mirtazapine
, or
trazodone
may more effectively treat cases of acute to
severe depression
and those who didn’t respond to monotherapy.
Atypical antidepressants
work by affecting the neurotransmitters in your brain. These neurotransmitters directly affect your levels of:
dopamine
norepinephrine
serotonin
Bupropion
On its own,
bupropion
effectively treats
MDD
. But a doctor may also prescribe it with other medications for depression that is difficult to treat.
Mirtazapine may be an option for people experiencing loss of appetite and
insomnia
. Its most common side effects are
unintentional weight gain
and sedation.
However, in-depth studies on its use as a combination medication aren’t available.
Antipsychotics
aripiprazole
brexpiprazole
extended-release quetiapine
cariprazine
Current research also suggests a benefit of taking SSRIs and an antipsychotic for those with
MDD with psychosis
.
A
2024 review
of 16 studies found that the combination of an SSRI and an antipsychotic medication showed higher treatment responses than a placebo in those with MDD with features of psychosis.
unintentional
weight gain
changes in muscle control or movement (
tardive dyskinesia
)
metabolic syndrome
Carefully consider the pros and cons of antipsychotics with your doctor. Their side effects may prolong or worsen some
depression symptoms
.
L-triiodothyronine
Some doctors use L-triiodothyronine (T3) in combination with SSRIs.
Research from 2021
suggests that T3 with an SSRI may lead to a faster response to treatment compared with taking an SSRI alone for older men. But more research is necessary.
The typical starting dose of T3 is
25 micrograms (mcg)
daily. If that dosage doesn’t provide the desired results after 1 to 2 weeks, they may increase it to
50 mcg daily
.
Stimulants
Dextroamphetamine (
Dexedrine
) and
methylphenidate (Ritalin)
are stimulants that medical professionals may use to treat depression. Doctors may prescribe them alone or in combination with antidepressant medications.
Many clinicians find that supplementing antidepressants with low doses of stimulants, such as
methylphenidate
,
may help improve depression
that doesn’t respond well to treatment.
However, not all clinical trials have shown benefits from this strategy.
Stimulants are most helpful when the desired effect is a quick response. People with severe depression symptoms or other conditions, such as chronic illnesses, may be good candidates for this combination.
Monotherapy’s success rates
are low
compared to combination therapy with a certain type of antidepressant. Many researchers
and doctors believe combination treatments are a first-line approach to treating MDD and treatment-resistant depression.
Many doctors will still begin treatment with a single antidepressant medication. You’ll need to give it time to work before ruling it out as ineffective.
If the medication doesn’t work as desired after a trial period — usually about
6 to 8 weeks
— your doctor may change your medication or add one to see whether the combination helps.

# Combination Medication Therapies for Depression

[Medically reviewed]() by [Yalda Safai, MD, MPH]() — Written by [Kimberly Holland]() and Dana Robinson — [Updated on November 15, 2024]()
- [Role of medications](https://www.healthline.com/health/depression/combination-therapies#role-of-medications)
- [Atypical antidepressants](https://www.healthline.com/health/depression/combination-therapies#atypical-antidepressants)
- [Takeaway](https://www.healthline.com/health/depression/combination-therapies#takeaway)
### Key Takeaways
- If you have major depressive disorder (MDD) and your symptoms don’t respond to a single antidepressant, combining specific antidepressants may be more effective.
- Atypical antidepressants, such as bupropion, can be used alone or with SSRIs or SNRIs to treat MDD. Antipsychotics may also be effective when other treatments don’t work or for MDD with psychosis.
- If a single antidepressant isn’t working after 6 to 8 weeks, a doctor may adjust the medication or add another to the regimen to improve effectiveness. Only a healthcare professional can advise if it’s safe to combine prescription medications.
If you have [major depressive disorder (MDD)](https://www.healthline.com/health/clinical-depression), you may be taking an antidepressant.
Combination drug therapy is a type of treatment that many doctors and psychiatrists have been increasingly using during the past decade.
## [The role of medications]()
Until recently, doctors prescribed an [antidepressant](https://www.healthline.com/health/depression/antidepressants-pros-and-cons) medication from only a single class of drugs, one medication at a time, called monotherapy.
Doctors generally start at a lower dosage and increase it before ruling it out as ineffective. If that happens, they might try another medication within that class or switch to another class of antidepressants entirely.
[Research from 2022](https://jamanetwork.com/journals/jamapsychiatry/fullarticle/2789300) now suggests that taking a combination of a specific class of antidepressants that includes mianserin, [mirtazapine](https://www.medicalnewstoday.com/articles/mirtazapine-oral-tablet), or [trazodone](https://www.healthline.com/health/drugs/trazodone-oral-tablet) may more effectively treat cases of acute to [severe depression](https://www.healthline.com/health/depression/crippling-depression) and those who didn’t respond to monotherapy.
## [Atypical antidepressants]()
[Atypical antidepressants](https://www.ncbi.nlm.nih.gov/books/NBK538182/) work by affecting the neurotransmitters in your brain. These neurotransmitters directly affect your levels of:
- [dopamine](https://www.healthline.com/health/dopamine-effects)
- norepinephrine
- [serotonin](https://www.healthline.com/health/mental-health/serotonin)
### Bupropion
On its own, [bupropion](https://www.healthline.com/health/bupropion-oral-tablet) effectively treats [MDD](https://www.healthline.com/health/clinical-depression). But a doctor may also prescribe it with other medications for depression that is difficult to treat.
Bupropion is one of the most commonly used combination therapy medications. Medical professionals often use it with [selective serotonin reuptake inhibitors (SSRIs)](https://www.healthline.com/health/depression/selective-serotonin-reuptake-inhibitors-ssris) and [serotonin-norepinephrine reuptake inhibitors (SNRIs)](https://www.healthline.com/health/depression/serotonin-norepinephrine-reuptake-inhibitors-snris).
People who’ve experienced severe [side effects](https://www.healthline.com/health/antidepressant-side-effects) from other [antidepressant medications](https://www.healthline.com/health/depression/medication-list) generally tolerate bupropion. It may also relieve some of the [sexual side effects](https://www.healthline.com/health/erectile-dysfunction/antidepressant-sexual-side-effects) associated with some SSRIs and SNRIs.
Mirtazapine may be an option for people experiencing loss of appetite and [insomnia](https://www.healthline.com/health/types-of-insomnia). Its most common side effects are [unintentional weight gain](https://www.healthline.com/health/antidepressants-that-cause-weight-gain) and sedation.
However, in-depth studies on its use as a combination medication aren’t available.
### Antipsychotics
[Research](https://psychiatryonline.org/doi/10.1176/appi.ajp.20230025) published in 2023 suggests atypical [antipsychotics](https://www.healthline.com/health/mental-health/what-are-antipsychotics) may effectively treat [treatment-resistant depression](https://www.healthline.com/health/treatment-resistant-depression). Food and Drug Administration (FDA) approved antipsychotics include:
- [aripiprazole](https://www.healthline.com/health/aripiprazole-oral-tablet)
- brexpiprazole
- extended-release quetiapine
- [cariprazine](https://www.healthline.com/health/drugs/vraylar)
Current research also suggests a benefit of taking SSRIs and an antipsychotic for those with [MDD with psychosis](https://www.healthline.com/health/depression/psychotic-depression).
A [2024 review](https://www.thelancet.com/journals/lanpsy/article/PIIS2215-0366\(24\)00006-3/abstract) of 16 studies found that the combination of an SSRI and an antipsychotic medication showed higher treatment responses than a placebo in those with MDD with features of psychosis.
[Antipsychotics](https://www.healthline.com/health/mental-health/what-are-antipsychotics), however, may have some [side effects](https://www.ncbi.nlm.nih.gov/books/NBK519503/):
- unintentional [weight gain](https://www.healthline.com/health/mental-health/weight-gain-on-antipsychotics)
- changes in muscle control or movement ([tardive dyskinesia](https://www.healthline.com/health/tardive-dyskinesia))
- [metabolic syndrome](https://pmc.ncbi.nlm.nih.gov/articles/PMC8001502/)
Carefully consider the pros and cons of antipsychotics with your doctor. Their side effects may prolong or worsen some [depression symptoms](https://www.healthline.com/health/video/5-symptoms-depression).
### L-triiodothyronine
Some doctors use L-triiodothyronine (T3) in combination with SSRIs.
[Research from 2021](https://www.sciencedirect.com/science/article/abs/pii/S2468171720300144) suggests that T3 with an SSRI may lead to a faster response to treatment compared with taking an SSRI alone for older men. But more research is necessary.
The typical starting dose of T3 is [25 micrograms (mcg)](https://labeling.pfizer.com/showlabeling.aspx?id=703) daily. If that dosage doesn’t provide the desired results after 1 to 2 weeks, they may increase it to [50 mcg daily](https://www.psychiatrist.com/jcp/thyroid-hormone-use-in-mood-disorders/).
### Stimulants
Dextroamphetamine ([Dexedrine](https://www.healthline.com/health/drugs/dextroamphetamine-oral-tablet)) and [methylphenidate (Ritalin)](https://www.medicalnewstoday.com/articles/drugs-ritalin) are stimulants that medical professionals may use to treat depression. Doctors may prescribe them alone or in combination with antidepressant medications.
Many clinicians find that supplementing antidepressants with low doses of stimulants, such as [methylphenidate](https://www.healthline.com/health/drugs/methylphenidate-oral-tablet), [may help improve depression](https://link.springer.com/article/10.1007/s40501-023-00307-4) that doesn’t respond well to treatment.
However, not all clinical trials have shown benefits from this strategy.
Stimulants are most helpful when the desired effect is a quick response. People with severe depression symptoms or other conditions, such as chronic illnesses, may be good candidates for this combination.
## [The takeaway]()
Monotherapy’s success rates [are low](https://www.aafp.org/pubs/afp/issues/2022/1000/poems-antidepressant-therapy.html) compared to combination therapy with a certain type of antidepressant.

| Readable Markdown | Combination drug therapy is a type of treatment that many doctors and psychiatrists have been increasingly using during the past decade.
Until recently, doctors prescribed an [antidepressant](https://www.healthline.com/health/depression/antidepressants-pros-and-cons) medication from only a single class of drugs, one medication at a time, called monotherapy.
Doctors generally start at a lower dosage and increase it before ruling it out as ineffective. If that happens, they might try another medication within that class or switch to another class of antidepressants entirely.
[Research from 2022](https://jamanetwork.com/journals/jamapsychiatry/fullarticle/2789300) now suggests that taking a combination of a specific class of antidepressants that includes mianserin, [mirtazapine](https://www.medicalnewstoday.com/articles/mirtazapine-oral-tablet), or [trazodone](https://www.healthline.com/health/drugs/trazodone-oral-tablet) may more effectively treat cases of acute to [severe depression](https://www.healthline.com/health/depression/crippling-depression) and those who didn’t respond to monotherapy.
[Atypical antidepressants](https://www.ncbi.nlm.nih.gov/books/NBK538182/) work by affecting the neurotransmitters in your brain. These neurotransmitters directly affect your levels of:
- [dopamine](https://www.healthline.com/health/dopamine-effects)
- norepinephrine
- [serotonin](https://www.healthline.com/health/mental-health/serotonin)
Bupropion
On its own, [bupropion](https://www.healthline.com/health/bupropion-oral-tablet) effectively treats [MDD](https://www.healthline.com/health/clinical-depression). But a doctor may also prescribe it with other medications for depression that is difficult to treat.
Mirtazapine may be an option for people experiencing loss of appetite and [insomnia](https://www.healthline.com/health/types-of-insomnia). Its most common side effects are [unintentional weight gain](https://www.healthline.com/health/antidepressants-that-cause-weight-gain) and sedation.
However, in-depth studies on its use as a combination medication aren’t available.
Antipsychotics
- [aripiprazole](https://www.healthline.com/health/aripiprazole-oral-tablet)
- brexpiprazole
- extended-release quetiapine
- [cariprazine](https://www.healthline.com/health/drugs/vraylar)
Current research also suggests a benefit of taking SSRIs and an antipsychotic for those with [MDD with psychosis](https://www.healthline.com/health/depression/psychotic-depression).
A [2024 review](https://www.thelancet.com/journals/lanpsy/article/PIIS2215-0366\(24\)00006-3/abstract) of 16 studies found that the combination of an SSRI and an antipsychotic medication showed higher treatment responses than a placebo in those with MDD with features of psychosis.
- unintentional [weight gain](https://www.healthline.com/health/mental-health/weight-gain-on-antipsychotics)
- changes in muscle control or movement ([tardive dyskinesia](https://www.healthline.com/health/tardive-dyskinesia))
- [metabolic syndrome](https://pmc.ncbi.nlm.nih.gov/articles/PMC8001502/)
Carefully consider the pros and cons of antipsychotics with your doctor. Their side effects may prolong or worsen some [depression symptoms](https://www.healthline.com/health/video/5-symptoms-depression).
L-triiodothyronine
Some doctors use L-triiodothyronine (T3) in combination with SSRIs.
[Research from 2021](https://www.sciencedirect.com/science/article/abs/pii/S2468171720300144) suggests that T3 with an SSRI may lead to a faster response to treatment compared with taking an SSRI alone for older men. But more research is necessary.
The typical starting dose of T3 is [25 micrograms (mcg)](https://labeling.pfizer.com/showlabeling.aspx?id=703) daily. If that dosage doesn’t provide the desired results after 1 to 2 weeks, they may increase it to [50 mcg daily](https://www.psychiatrist.com/jcp/thyroid-hormone-use-in-mood-disorders/).
Stimulants
Dextroamphetamine ([Dexedrine](https://www.healthline.com/health/drugs/dextroamphetamine-oral-tablet)) and [methylphenidate (Ritalin)](https://www.medicalnewstoday.com/articles/drugs-ritalin) are stimulants that medical professionals may use to treat depression. Doctors may prescribe them alone or in combination with antidepressant medications.
Many clinicians find that supplementing antidepressants with low doses of stimulants, such as [methylphenidate](https://www.healthline.com/health/drugs/methylphenidate-oral-tablet), [may help improve depression](https://link.springer.com/article/10.1007/s40501-023-00307-4) that doesn’t respond well to treatment.
However, not all clinical trials have shown benefits from this strategy.
Stimulants are most helpful when the desired effect is a quick response. People with severe depression symptoms or other conditions, such as chronic illnesses, may be good candidates for this combination.
Monotherapy’s success rates [are low](https://www.aafp.org/pubs/afp/issues/2022/1000/poems-antidepressant-therapy.html) compared to combination therapy with a certain type of antidepressant. Many researchers and doctors believe combination treatments are a first-line approach to treating MDD and treatment-resistant depression.
Many doctors will still begin treatment with a single antidepressant medication. You’ll need to give it time to work before ruling it out as ineffective.
If the medication doesn’t work as desired after a trial period — usually about [6 to 8 weeks](https://www.healthquality.va.gov/guidelines/MH/mdd/) — your doctor may change your medication or add one to see whether the combination helps.
