These drugs are called sleeping pills and are usually quite effective in solving insomnia, at least for a time. And is that doctors usually do not allow prolonged consumption since in addition to having side effects such as daytime sleepiness and lightheadedness, they can cause addiction. Therefore, they are a good way to temporarily relieve insomnia while psychological therapies and changes in lifestyle continue to work.

There are also sleeping pills that do not need a prescription, that is, they are available over the counter. But these also have side effects if consumed for too long. For this reason, pharmacological therapies are more of a momentary relief than a definitive solution. Insomnia must be fought by detecting the root cause and changing lifestyle habits .
