I'd like a 1/2 tablet, capsule... option.
Also to note if prescribed by another provider ex Cardiology prescribes Coumadin, etc...
Many prescription writers break the SIG in parts selectable from multiple drop down boxes:
Choose # (1/2, 1, 1 1/2, 2,...)
Choose Vehicle (Tablet, Capsule, Drop,...)
Choose Schedule (QAC, QAM, QD, QPM, QHS, BID, TID...)
Choose (PRN)
Choose (BY OTHER)
Maybe default to most common SIG.
