Common questions about mirtazapine
Below you’ll find answers to a few commonly asked questions about mirtazapine.
Can mirtazapine be used for sleep or anxiety?
Possibly. Mirtazapine isn’t approved for sleep problems or anxiety. But doctors may choose to prescribe it for these purposes, especially if you have depression. It’s called an off-label use when doctors prescribe a drug for a condition other than its approved uses. Mirtazapine is approved for depression treatment.
It’s important to note that mirtazapine can cause sleepiness as a side effect, so doctors usually recommend taking it at bedtime.
Talk with your doctor if you’d like to learn more about taking mirtazapine for sleep or anxiety.
What brand names are available for mirtazapine?
Mirtazapine oral tablet is available as the brand-name drug Remeron. The mirtazapine orally disintegrating tablet is available as the brand-name drug Remeron SolTab.
If you’re interested in the brand-name versions of mirtazapine, talk with your doctor or pharmacist.
Is mirtazapine safe for older adults?
Yes, but there are precautions for older adults (ages 65 years and over) taking mirtazapine.
In older adults, sleepiness caused by mirtazapine can lead to confusion and being overly sleepy. Older adults also tend to have reduced kidney function and other changes in organ function. This can lead to a higher level of mirtazapine in the body and other problems.
Due to these risks, doctors usually start with a low dose of mirtazapine in older adults.
If you’re concerned about taking mirtazapine because of your age, talk with your doctor or pharmacist.
Does mirtazapine cause withdrawal symptoms?
Yes, mirtazapine can cause withdrawal symptoms, also called discontinuation syndrome. These are symptoms that can occur if you stop taking a drug your body has become dependent on. Suddenly stopping the drug increases the risk of these symptoms.
Withdrawal symptoms can include:
- abnormal dreams
- anxiety or agitation
- dizziness
- electric shock sensations or other strange feelings
- fatigue (low energy)
- headache
- nausea and vomiting
- sweating
- shaking you can’t control
Do not stop taking mirtazapine without talking with your doctor. They can answer any questions about stopping the drug and how to do it safely.
How does mirtazapine work? And how long does it take to start working?
Mirtazapine is thought to work by balancing chemical messengers in the brain. These chemical messengers are called neurotransmitters. The ones that mirtazapine affects likely play a role in your mood. Balancing them can help to treat depression.
When you start mirtazapine, some of your symptoms may ease within 1–2 weeks. Like other antidepressants, it can take several weeks to feel the full effect of mirtazapine.
Talk with your doctor or pharmacist to find out more about what to expect with mirtazapine.
Is mirtazapine similar to trazodone?
Yes, mirtazapine and trazodone are similar. They’re both antidepressants that affect similar chemical messengers in the brain. Their side effects and warnings are also similar. But the drugs do have some differences, such as their dosing.
If you have questions about trazodone and how it compares with mirtazapine, talk with your doctor or pharmacist.

Boxed warning: Risk of suicidal thoughts and behaviors
Mirtazapine has a boxed warning about the risk of suicidal thoughts and behaviors in certain people. Boxed warnings are the most serious warnings from the Food and Drug Administration (FDA).
With antidepressants such as mirtazapine, there is an increased risk of suicidal thoughts and actions in children, teenagers, and young adults (ages 24 years and younger). The risk is highest during the first few months of treatment and during dosage changes.
