Grains Re: Pharmacy Conversions..

[Guest guest]

Dear All,

Most of the doctors who once wrote for grain have retired or died.

metric replaced the grain, but only after the numbers 1,2,3,and 4 were

used to denote the mgs or grains.

such as in Tylenol + codiene

#4 = 60 mg = 1 grain

#3 = 30 mg = 1/2 grain

#2 = 15 mg = 1/4 grain

#1 = 7.5 mg = 1/8 grain

It is being phased out.

One reason it remains in opiates is becauase it is confusing to

non-pharmacy persons, which means less chance for counterfeit scripts

and also greater chance that forger will get caught.

Now with the advent of Electronic scripts and also Security

Prescription Forms replacing triplicates you will see less forgeries.

But old habits die hard.

Any one ahve any security prescription forgery stories???

Respectfully,
