I'd go with Magpie's interpretation.  All Snape actually 
says is "You should drink that directly, Lupin."  As in 
"before you forget, Lupin."  What people are reading in 
to it is the idea that Lupin needs to drink it before it 
loses its effectiveness.  

Lupin is being dismissive.  "Very good, Jeeves, just 
leave it on the chiffonier and then you may go."  Snape 
is subtly reminding him that he, Lupin, is the one with 
the secret, which Snape is keeping--for the time being.

That still doesn't answer the question of why missing 
one dose on the night of the full moon would allow Lupin 
to transform into a vicious as opposed to a tame werewolf 
if he had been taking it the week before, as he says he 
needs to.  Maybe there is a dosage effect and Lupin that 
night, in his transformed state, was not as violent as he 
would have been without any Wolfsbane at all the previous 
week, but neither was he as harmless as he would have been 
if he had taken the final dose.
