Sleeping pills are divided into benzodiazepines and newer non-benzodiazepine sleeping pills, but regardless of the type, the recommended dosage is between one and two pills at a time. The most commonly used new non-benzodiazepine sleeping pill, zolpidem, for example, comes in a dosage of ten milligrams, and can be taken by normal patients who do not have other underlying diseases, weaknesses, or organ dysfunctions, ten milligrams at a time, thirty minutes before bedtime every night. If there are other organ insufficiencies, or light weight or weakness, it is only recommended to take five milligrams, thirty minutes before bedtime. If, after taking it, you do not fall asleep within half an hour, you can take it a second time in about an hour, and it is recommended to take a dose of five milligrams this time. If sleeping pills are taken in excessive amounts, they may cause excessive sedation and, in severe cases, inhibit breathing and circulation, with the possibility of causing life-threatening effects.
