Mirtazapine, sold under the brand name Remeron, primarily treats major depressive disorder (MDD). Doctors also frequently prescribe it for anxiety disorders, particularly generalized anxiety disorder (GAD), and sometimes for insomnia.
Depression Treatment
Mirtazapine works by increasing the release of serotonin and norepinephrine in the brain, neurotransmitters crucial for mood regulation. Typical starting dose for depression is 15mg, often increasing gradually depending on response. It usually takes several weeks to see significant improvement.
- Common side effects include increased appetite and weight gain, drowsiness, and dry mouth. Always inform your doctor about all medications you are taking, including over-the-counter drugs and supplements, to avoid potential interactions. Never suddenly stop taking Mirtazapine; gradually reduce your dose under your doctor’s guidance to minimize withdrawal symptoms.
Anxiety and Insomnia Treatment
While not the first-line treatment for anxiety, Mirtazapine’s sedative properties can benefit individuals with GAD who experience sleep problems. For insomnia, it’s often prescribed at a lower dose than for depression.
Your doctor will determine the appropriate dosage and monitor your progress. Expect the sedative effect to be most noticeable at the beginning of treatment. Report any unexpected side effects or lack of improvement to your doctor promptly.
Prescribing Considerations
Mirtazapine is not suitable for everyone. Your doctor will assess your medical history and current medications before prescribing it. Certain conditions, like glaucoma or liver/kidney impairment, may require dose adjustments or alternative treatments. Pregnancy and breastfeeding should also be discussed with your doctor.
