Drug info - Splitting generic Alprazolam tablets?

[GreatWonder]

SWIM has noticed there's only a marginal difference in price between 0.5mg generic Alprazolam and 1mg but still enjoys the mild anti-anxiety effects that the occasional 0.5mg provides them with.

SWIM obviously knows that the 2mg Xanax bars are OK and even intended to be split into 4 x 0.5mg doses and just wondered if generic Alprazolam tablets followed this same rule? IE clean splitting a 1mg Alprazolam would create 2 even 0.5mg doses? As I'm sure SWIM read somewhere this rule is not the same for all medications due to how the drug is contained in the tablet.

Any SWIY's OK to 'OK' this?
