The industry standard storage temperatures against which medicines are tested are -20°C, 2-8°C, 25°C, 30°C and 45°C. To support a shelf life, real time data for a minimum of three typical batches are required. The shelf life of a medicine is constrained by no chemical degradation greater than 0.2% by weight of the active principle based on the upper 95% confidence interval, or other significant changes in properties or behaviour. The shelf life applies to the supply chain and not the end user, i.e. medicines are designed to be used fairly soon after being supplied to the end user. If storage conditions for the end user apply these will be specified seperately.
So a week at 9°C would not be likely to cause any significant issues. Remember Arrhenius. Reaction rates increase with temp, typically doubling with each 10°C rise in temperature.
