I work in pharma and you probably don't want to freeze or refrigerate them unless the package insert says freezing or refrigerated storage is acceptable. You don't just have to worry about the ALP, you have to consider the excipents (other ingredients). At pharma companies, we have to carry out freeze/thaw and temperature excursion studies to support approval and that info goes directly the package insert.
I couldn't find a PI for Farmpram but Pfizer's instructions state: "store at room temperature 20C to 25C (68 to 77F). [See the USP]"
Now that USP statement is important. I have access to USP online and USP defines Room temperature (also referred to as ambient temperature) as "The temperature prevailing in a working environment." Controlled room temperature (which is what is important to us": The temperature maintained thermostatically that encompasses the usual and customary working environment of 20°–25° (68°–77° F). The following conditions also apply. Mean kinetic temperature not to exceed 25°. Excursions between 15° and 30° (59° and 86° F) that are experienced in pharmacies, hospitals, and warehouses, and during shipping are allowed. Provided the mean kinetic temperature does not exceed 25°, transient spikes up to 40° are permitted as long as they do not exceed 24 h. Spikes above 40° may be permitted only if the manufacturer so instructs. Articles may be labeled for storage at “controlled room temperature” or at “20°–25°”, or other wording based on the same mean kinetic temperature [see also Good Storage and Distribution Practices for Drug Products á1079ñ, Quality Management System, Environmental Management System, Mean Kinetic Temperature (MKT) Calculation]. An article for which storage at Controlled room temperature is directed may, alternatively, be stored and shipped in a cool place or refrigerated, unless otherwise specified in the individual monograph or on the label.
So if it COUDN'T be refrigerated, it should be in the packaging but in reality, there's not a SHORT-TERM issue with refrigerated storage.
The three biggest threats to stability are moisture, light, and temperature. I would put them in the food saver packaging, keep them in a dark place, and you should be good to go!
