Mirtazapine is also a good choice in depressed patients with significant anxiety or insomnia. Although mirtazapine has been used successfully in Europe for a number of years, its place in the care of patients with depression in the United States has not yet been established.

Antidepressants remain the cornerstone of treatment of depression by primary care physicians. Table 1 compares selected antidepressants in terms of dosages and costs. A recent antidepressant introduced to the U. Montvale, N. Cost to the patient will be higher, depending on prescription filling fee. As with any new drug, mirtazapine's place in the treatment of depression is not yet clear. Selective serotonin reuptake inhibitors SSRIs have become the drugs of choice in the treatment of depression.

Mirtazapine is a tetracyclic piperazinoazepine, which has a different structure from any other currently used antidepressant. It enhances central noradrenergic and serotonergic activity by blocking alpha 2 receptors and selectively antagonizing 5HT 2 and 5HT 3 receptors.

Mirtazapine is well absorbed without regard to food intake. It demonstrates linear kinetics over its usual dosage range and reaches peak plasma level approximately two hours after an oral dose.

Mirtazapine is metabolized in the liver via the P cytochrome oxidase pathway, inhibiting cytochromes 2D6, 1A2 and 3A4. It is excreted in the urine. Clearance of the drug is diminished in the presence of liver or renal impairment. Therefore, a lower dosage is recommended in elderly patients and those with liver or renal dysfunction. Mirtazapine is currently approved for use in adults. Because it is unknown if mirtazapine is secreted in breast milk, it should be used with caution in breast-feeding mothers.

The U. Food and Drug Administration has labeled mirtazapine as a pregnancy category C drug. In the treatment of depression, as measured by Hamilton Depression rating scales, mirtazapine is clearly superior to placebo. Mirtazapine is especially helpful in patients with depression who are anxious; this drug has been shown to reduce anxiety and has even been used to relieve preoperative anxiety and insomnia in patients having gynecologic surgery.

The most common side effects of mirtazapine are dose-dependent drowsiness 54 percent , dry mouth 25 percent , increased appetite 17 percent , weight gain 12 percent and dizziness 7 percent. These side effects tend to improve with time.

The most serious side effect is agranulocytosis, which occurs in approximately one in 1, patients. This incidence is no higher than the incidence of other antidepressants. To date, all patients with this complication have recovered completely when the medication was stopped. A complete blood count and ALT measurement may be obtained if symptoms or signs suggest a need. Mirtazapine has few, if any, cardiac effects and causes very little orthostatic hypotension.

Information about overdose of mirtazapine in suicide attempts is limited because the drug is so new. However, to date no deaths have been recorded, and seizures and cardiotoxicity have not been noted in case reports. Excessive sedation appears to be the main effect of an overdose of mirtazapine. Multiple hepatic pathways are used in the metabolism of mirtazapine, so clinically significant drug-drug interactions are unlikely to occur.

The usual starting dosage is 15 mg, with a usual dosage range of 15 to 30 mg per day. It is available in mg and mg scored tablets. Already a member or subscriber? Log in.

Remeron is the brand name for Mirtazapine, a prescription Antidepressant that belongs to a class of drugs called Tetracyclic Antidepressants TeCAs. Remeron is mainly used to treat major depressive disorder MDD , but is occasionally prescribed to treat other mental health issues such as generalized anxiety disorder and social anxiety.

The drug works by altering the levels of neurotransmitters in the brain and balancing the chemicals of the central nervous system. Patients taking the medication typically do so over a period of 40 weeks. Remeron can improve mood, feelings of well-being, sleep, and appetite in consumers while also decreasing nervousness.

In addition to these benefits, the medication can produce a variety of negative and potentially harmful effects as well.

These side effects range from mild to severe and can include any of the following:. Learn More. Other serious side effects such as suicide risk , behavioral changes, and an increase in depression have been documented while taking Remeron. Reports of increased anxiety, agitation, panic attacks, irritability, and hostility have also been documented during the course of treatment.

In rare cases, some individuals may develop a very serious condition called serotonin syndrome. Remeron increases serotonin; if too high of a dose is taken, or if the medicine is mixed with other drugs that increase serotonin, the disorder can manifest.

The risk of experiencing these negative side effects is also increased when the drug is abused. Drug abuse constitutes any situation in which the medication is used either without a prescription or not as explicitly prescribed, such as taking higher dosages or mixing the drug with alcohol. Many individuals will take more of the drug than prescribed to feel the effects faster or use Remeron to counteract the effects of stimulant drugs, such as Cocaine. Diverted use such as this increases the risk of serious complications such as abdominal cramping, convulsions, and cognitive function.

Remeron should also never be taken with other Antidepressants, specifically Monoamine Oxidase Inhibitors MAOIs , as each substance increases the sedative effects of the other.

This combination can significantly raise the risk of adverse reactions. Like the majority of Antidepressants, Remeron is generally considered to be nonaddictive; however, the drug can cause physical dependence. Those that try to reduce their dose or stop taking Remeron altogether will start to experience uncomfortable withdrawal symptoms, which can cause some people to keep taking the drug despite wanting to quit.

Withdrawal symptoms include rebound depression, irritability, nausea, dizziness, vomiting, nightmares, headache, and paresthesia a prickling, tingling sensation on the skin. These symptoms can lead to a cycle of addiction and dependence where individuals build up a tolerance and effectively take more and more of the medication in an effort to prevent the debilitating effects of withdrawal.

Another potential side effect of Remeron addiction is overdose if an individual takes too much of the drug. A Remeron overdose can cause severe health problems such as cardiac arrest, dangerously low blood pressure, and seizures. In extreme cases, respiratory depression and even death can occur. Signs of an overdose include chest pain, hallucinations, vomiting, rapid heartbeat, slurred speech, trouble breathing, and extreme drowsiness. The risk of overdose is significantly increased when Remeron is combined with other drugs, particularly alcohol or Benzodiazepines.

This combination can cause extreme drowsiness and respiratory depression, but many people that abuse Remeron will mix the substances regardless to increase the intoxication experienced. Make a Call The National Institute on Drug Abuse estimates that more than 50 million Americans aged 12 or over have abused a prescription drug at least once in their lives.
