Everything you need to know about Remeron (mirtazapine)

What is Remeron (mirtazapine), and how does it work?

Remeron (mirtazapine), commonly sold under the brand name Remeron, is an antidepressant used to treat depression in adults. It’s a type of medication called a noradrenergic and specific serotonergic antidepressant (NaSSA), which helps restore the balance of neurotransmitters—chemical messengers in your brain that affects your mood.

This antidepressant increases the neurotransmitters serotonin and noradrenaline. Boosting the levels of these mood-enhancing, natural chemicals in your brain can ease symptoms of depression, help you feel calm, and give you a better sense of well-being.

Remeron (mirtazapine) is used to treat depression, but the benefits you experience will depend on your diagnosis and symptoms. If you’ve tried another antidepressant and it didn’t relieve your symptoms, or it caused side effects, Remeron (mirtazapine) can offer an excellent alternative. It’s also a good choice for people experiencing depression and anxiety or difficulty sleeping.

At Brightside, we use Remeron (mirtazapine) to help with symptoms such as:

  • Agitation and restlessness

  • Difficulty concentrating
  • Feeling sad, hopeless, empty, or worthless

Will Remeron (mirtazapine) work for me?

Medications don’t have the same effect on everyone—each person is different. Your age, sex, health history, and genetic makeup impact how a particular medication works for you. Your response to medications can also be affected by other medications you’re taking.

At Brightside, we consider all aspects of your health and lifestyle to design a treatment plan that meets your unique needs. We use our expertise to find the medications and therapies we believe will work best for you. Whether that means adjusting your dosage or trying a different medication, we take the time to ensure you get the best results as quickly as possible.

Typically, providers begin you on a low dose of Remeron (mirtazapine) and then gradually increase it over several weeks. Some people notice improvements in sleep, energy, and appetite within the first few weeks, but it can take up to six or eight weeks to feel improvement in your mood or experience the full benefits.

If you don’t notice an improvement right away, it doesn’t mean the medication isn’t working. Sometimes it takes a little longer for some people to feel the effects, so you must give it enough time to work.

We understand you want to feel better right away, but it may take some time. We’re here to support you and ease your concerns so don’t hesitate to talk to your provider—we offer telehealth services and provider consultations that can be scheduled within 48 hours.
