Dexzopiclone has side effects when taken for a long period of time. Dexzopiclone belongs to the non-benzodiazepine class of sedative-hypnotics and is mainly used for the treatment of insomnia in clinical practice. Common adverse effects of dexzopiclone in clinical use include discomfort or unpleasantness of taste, dizziness, nervousness, dry mouth, headache, sedation, and then, at higher doses, a postictal sedative effect the following day, and an effect on memory as the dose increases. Dexzopiclone is not limited to short-term use, and long-term use studies of up to 6 months suggest that dexzopiclone has not been significantly tolerated or dependent. However, its long-term use is theorized to be addictive, with an increased risk especially in sensitive individuals or those with a history of drug addiction. Long-term use of dexzopiclone is associated with symptomatic rebound and insomnia on discontinuation, and the dosage should be tapered to minimize the occurrence of withdrawal reactions. It is contraindicated in people who are allergic to the product and the components contained in it, in patients with decompensated respiratory insufficiency, in patients with myasthenia gravis. Use with caution in pregnant and lactating women. The use of dexzopiclone needs to be used under the evaluation of a physician, do not prolong its use at will.
