Addictiveness is the side effect that people fear most. Many people reject sleeping pills precisely because they are worried that they will become addicted and cannot quit after taking them, and some people even wrongly believe that taking sleeping pills will make people stupid. This is actually a big misconception. Most sleeping pills are safe and have very low addictive properties. Currently, to address the addiction problem of sleeping pills, WHO stipulates that it is best to use any kind of sleeping pill for no more than 4 weeks as prescribed by a doctor. The clinical recommendation is that the same sleeping pill should not be taken continuously for more than 2-4 weeks. Therefore, addiction can be avoided by using sleeping pills rationally and changing them regularly (about 2-4 weeks). In addition, common side effects of sleeping pills include dizziness, drowsiness, lack of concentration and unstable walking. These symptoms are called “hangover reaction” by doctors, which means that it is like drinking at night and not waking up the next day. In this case, the patient should reduce the dose of the drug or switch to another drug under the guidance of the doctor.
