welcome to hcm
the tablet taken by yous girl friend has sedative property so she will feel sleepy.
but why she has taken 8 tablet at a time it very harmful.
if she is taking this tablet for any allergic manifestations or any cold
than standard dose will be one night dosing
maximum 2 tablets 12 hours apart.
advised not to drive after taking this tablet.
thankyou for your query
