Thanks for asking!

Clinical history is needed, otherwise only hit and trial

It is not recommended to give medical advice based on such limited history and information. As a general rule tapering is done over days to weeks depending on the purpose of prescribing and the patients history. But medical advice is highly specific to the patient. Also note Ativan is a regulated/controlled drug due to its safety profile, abuse potential and risks and side effects both while taking the medicine and when stopping suddenly after regular intake . It cannot /should not be  procured without a prescription.  Kindly contact your prescribing doctor or take a second opinion for a personalized opinion.

Start taking half for next few days and stop. Kindly do with the help of a psychiatrist

Hello If you are taking the medicine only for 4 days, can make it 1/2 mg for next 3 days and then stop It can be taken sos But better to consult Dr for resolving the issue that you need to take lorazepam

Currently you can stop it at once,but it's not a good option to keep it for SOS basis because ultimately you will end up taking it as and when needed and then the dosing may not remain as SOS.Consult a doctor and rule out any underlying physical/psychological conditions

If the duration is 4 days only u can stop it all of a sudden. Usual bzd are not advised beyond 4-6 weeks

To taper off start by reducing dose to 0.5 for 1st 5 days. And after that you can stop and take it on SOS, if needed. Please do make sure not to take sleeping pills frequently and rather consult a psychiatrist to treat the under lying issue.

Its important that regarding medicines you take advise after giving proper information.  Why was it given, why lorazepam was preferred are few questions that need to be discussed

Hi . Will need further history regarding the same to advise appropriately like the reason for which you were started on the medicine, duration and nature of symptoms etc. you need to gradually taper it off over a few weeks. Consult online for further suggestions

It u have taken only for 4 day's... U can stop it at once.
