How long does the effect of lorazepam last?

Według danych literaturowych początek działania lorazepamu - substancji czynnej zawartej w leku Lorafen, obserwuje się zwykle po ok. 30 minutach. Pełne działanie uspokajające osiąga się po ok. 1-1,5 godziny. Utrzymuje się ono przez ok. 6-8 godzin.

Lorafen 2.5mg - DAY action time, 1 tab swallowed about 22nd on Saturday. I don't even know when I fell asleep in the living room, I woke up in the bedroom around 11 o'clock and if it wasn't for household chores, believe me, I would sleep all day. I will add that I totally lost consciousness, I do not know how and when I went to the bedroom and no one moved me ;) Apparently body weight has no effect in this case, so said the doctor but I think that 2.5mg for my 46kg was too much. On Monday I walked like a shadow. But it must be admitted that the right dose will allow you to sleep specifically.

For @Domi: Yes, Lorabex contains the same active substance as Lorafen (lorazepam), so it works in the same way. The answer to the question about dose reduction has already been given to you here: https://www.gdziepolek.pl/opinie-i-pytania/85313/lorabex-czy-z-dawek-2-mg-rano-i-wieczorem-leku-lorabex-mozna-powoli-schodzic-d

Is it possible to take 2mg in the morning and 2mg in the evening and go down to the smallest dose? And does it work the same way as Lorafen? I took Lorafen and prescribed I have a replacement for lorabex
