Can there be sleep problems despite taking Relanium?

The use of benzodiazepines is associated with the development of tolerance to this group of drugs. This is the case with Relanium (diazepam). I do not know what dose of the drug is used, but in case of insomnia, you should take 5-15 mg before bedtime. We have two types of Relanium - 2 mg and 5 mg. If 5 tablets of 2 mg are used, the dose before bedtime is 10 mg (we still have 5 mg of stock up to the highest recommended dose for insomnia), but if 5 tablets of 5 mg are used, the dose before bedtime is already 25 mg, which is an amount exceeding the recommended dose used for insomnia. It also all depends on how long the drug is used, since you should not prolong the treatment with the full dose (15 mg) for more than 4 weeks. After a long time, tolerance to the drug may develop, i.e. the dose that previously helped to fall asleep, after a few weeks it will be insufficient, which will be associated with an increase in the dose - however, this will not be a good solution for health, because it may be associated with the development of addiction to the drug. Please contact your doctor to determine your further treatment regimen. I attach the leaflet of the preparation: https://www.gdziepolek.pl/produkty/66506/relanium-tabletki/ulotka/
