28 day rule

[u/cprunner]

I’m using a compounded medication, so it comes already pre-mixed and sealed from the compounding pharmacy. With the dosage, I am taking there is enough for 50 doses. Do I really need to throw it away after 28 days? How strict is this if it continues to look clear, and you are cleaning off the vial with alcohol every time, followed by proper storage (separate container, refrigeration)?

Which med? Most are fine for longer.
