Mirtazapine tablets can not only play a sedative role to improve insomnia and anxiety, but also have a good effect on depression. The dosage of Mirtazapine tablets to improve insomnia should be determined on a case-by-case basis, starting with a small dose of 15mg per tablet and not more than 3 tablets a day. When insomnia or depression symptoms improve significantly, the drug can be reduced or discontinued under the guidance of a doctor, or replaced by a drug without sedative effect. In addition, you should normally observe closely for cardiac or neurological side effects, and change the medication if symptoms such as limb tremors occur.
