Hi Dew, If the meds are strictly for break through and not a new routine daily dose you may not need 240. The 90 may be enough to bring in under control. I would call the PM and confirm the dose to be taken and how often. If in fact he does want you to take 2 every 6 hours daily and not PRN then tell him you are concerned that you won't have enough pills to last until your next appointment. Don't wait! Hope it kicks in fast for you.
