- Condition GuideCombined Care for Antidepressant Withdrawal SymptomsAntidepressant discontinuation symptoms can occur after dose reduction or cessation, including dizziness, nausea, sleep changes, sensory abnormalities, anxiety, and mood changes. These may differ from a recurrence of original depression or anxiety in terms of onset timing, types of symptoms, and response to re-administration, so they must be distinguished by the prescriber. Rather than concluding on your own that symptoms are a recurrence or treatment failure, create a daily record so that you and your prescriber can re-evaluate the pace of treatment. Suicidal thoughts, severe agitation, mania, psychosis, or dizziness so severe that you cannot stand require immediate priority for the prescriber or emergency medical care.→
- Condition GuideCombined Care for Sleeping Pill TaperingReducing sleeping pills is not a process of replacing medication with herbal medicine or stopping them within a fixed period. The prescriber determines the pace based on the type of medication, duration of use, comorbid conditions, and previous responses to reduction; Korean medicine treatment supports this plan by recording rebound insomnia, throbbing, gastrointestinal discomfort, and daytime functioning. Rather than focusing on a specific stop date, safely navigate the intervals agreed upon with your prescriber while recording fluctuations in sleep and daytime functioning. Seizures, changes in consciousness, severe confusion, thoughts of self-harm, or the combined use of alcohol and sedatives require immediate consultation with your prescriber or an emergency evaluation.→
- Medical GuideIf discomfort occurs after reducing or changing mental health medicationIf insomnia, anxiety, dizziness, or sensory abnormalities occur after reducing the dose or changing medication, please write the medication name, previous and current doses, the date of change, and the date the first symptoms appeared on a single line. Since withdrawal, rebound, and the recurrence of original symptoms can overlap, do not make a definitive judgment yourself or increase the dose again. In particular, sudden discontinuation of benzodiazepines can be dangerous, so an individual reduction plan must be established with the prescribing medical staff.→
