Hello,
Advising to use a drug beyound its expiry date can be a tricky affair if you are the prescribing physician.
Expiry date indicates that the primary drug may no longer be potent or may lose its potency in an erratic manner. The primary chemical may even become harmful. One needs to take into account the stabilit of the solvents, storage conditions etc. So, there is really no way of telling how potent this particular drug will be on Feb 1, 2017 unless it is tested.
I am attaching a few articles for your further reading but it would be nice if you can analyze for yourself if using the same drug is worth the risk? Or is it just cheaper and more convenient to buy a new batch.
Also, in the rare event of any unwanted effect happening who will be responsible? (since the manufacture has given you a guideline with expiry date that was willfully ignored)
1. Stability profiles of drug products extended beyond labeled expiration dates
2.
