MIZEST-7.5

# Mirtazapine 7.5 mg ## Short Description **Mirtazapine 7.5 mg** is an antidepressant belonging to the **noradrenergic and specific serotonergic antidepressant (NaSSA)** class. It is primarily used to treat **major depressive disorder (MDD)**. Mirtazapine can also have **sedating and appetite-stimulating effects**, which may be clinically useful in some patients with depression who experience insomnia or reduced appetite. However, **7.5 mg is below the usual antidepressant starting dose**, and lower doses are sometimes used for specific clinical reasons under medical supervision. > **Important:** Mirtazapine is a prescription medicine and should not be started, stopped or dose-adjusted without medical guidance. --- ## Key Benefits * Used for the treatment of **major depressive disorder**. * Helps improve symptoms such as persistent low mood and loss of interest. * May help improve **sleep** when depression is associated with insomnia. * May increase **appetite** in some patients. * Usually taken **once daily**, often at bedtime because of its sedating effects. * Does not belong to the SSRI class. --- ## Uses / Indications ### Major Depressive Disorder Mirtazapine is primarily indicated for the treatment of **major depressive disorder**. Depressive symptoms may include: * Persistent sadness * Loss of interest or pleasure * Low energy * Sleep disturbances * Changes in appetite * Difficulty concentrating * Feelings of worthlessness or guilt ### Sleep Problems Associated With Depression Because mirtazapine can cause drowsiness, clinicians may select it for patients whose depression is accompanied by **sleep difficulties**. > Mirtazapine is **not primarily approved as a sleeping medicine**, and using low-dose mirtazapine solely for insomnia should be discussed with a healthcare professional. ### Reduced Appetite Mirtazapine may increase appetite and body weight in some patients. This effect can sometimes be clinically useful when depression is accompanied by poor appetite or weight loss. --- ## How It Works Mirtazapine works differently from SSRIs and SNRIs. It primarily: * Blocks **central presynaptic alpha-2 adrenergic receptors**, increasing the release of norepinephrine and serotonin. * Blocks certain serotonin receptors, particularly **5-HT2 and 5-HT3 receptors**. * Strongly blocks **histamine H1 receptors**, which contributes to its sedative effect. ### In simple terms: **Mirtazapine → increases noradrenergic and selected serotonergic activity → helps regulate mood and depressive symptoms.** Its H1-antihistamine activity can also cause **sleepiness and increased appetite**. --- ## Dosage & Administration ### Adults The usual recommended starting dose for depression is generally: **15 mg once daily**, usually taken in the evening before bedtime. The dose may be adjusted by a healthcare professional based on response and tolerability. Typical therapeutic doses are generally within: **15–45 mg once daily.** ### About 7.5 mg **Mirtazapine 7.5 mg is a low strength and is below the usual recommended starting dose for major depression.** A healthcare professional may prescribe a lower dose in selected circumstances, but **7.5 mg should not be assumed to be an appropriate antidepressant dose for everyone**. ### Administration * Take once daily, preferably in the evening or at bedtime. * Take consistently at approximately the same time each day. * May generally be taken with or without food. * Swallow conventional tablets with water. * If using an orally disintegrating formulation, follow the product-specific instructions. ### Important Do not increase the dose yourself because the antidepressant effect may take **several weeks** to develop. --- ## Side Effects ### Common Side Effects Possible side effects include: * Sleepiness * Drowsiness * Increased appetite * Weight gain * Dry mouth * Constipation * Dizziness * Fatigue * Headache ### Other Possible Effects Some patients may experience: * Abnormal dreams * Peripheral edema * Nausea * Increased cholesterol or triglycerides * Low blood pressure, particularly when standing ### Serious Side Effects Seek urgent medical attention for: * Severe allergic reaction * Severe skin rash or blistering * Yellowing of the skin or eyes * Severe confusion * Fainting * Signs of infection such as fever, sore throat or mouth ulcers Rarely, mirtazapine can cause **agranulocytosis**, a potentially serious reduction in white blood cells. ### Suicidal Thoughts Like other antidepressants, mirtazapine may be associated with an increased risk of **suicidal thoughts or behavior in some children, adolescents and young adults**, particularly during the early stages of treatment or after dose changes. Any new or worsening suicidal thoughts require **prompt medical attention**. --- ## Precautions & Warnings ### Suicidal Thoughts and Mood Changes Monitor for: * New or worsening depression * Severe anxiety or agitation * Unusual behavioral changes * Suicidal thoughts * Self-harm thoughts Family members or caregivers should also be alert to significant changes in behavior. ### Drowsiness Mirtazapine can cause significant sedation, especially when starting treatment.

Avoid or minimize alcohol unless your healthcare professional advises otherwise. ### Weight Gain Mirtazapine can increase appetite and body weight.
