Hello, I currently get Interferon for my FeLV+ kitty, Shane, from Pet Health Pharmacy in Youngtown, Arizona <http://www.pethealthpharmacy.com/>. The dilution is 30 IU/ml. I give 1 ml. orally once daily for seven days, every other week (seven days on/seven days off). The instructions on the label are as follows:
"If using immediately (liquid), store in refrigerator. Expires in one month. If storing, keep in freezer. Expires in six months." According to this, even when frozen it has a limited shelf life (six months). Since, on the seven days on/seven days off schedule, I would never use up the entire prescription within one month, here is what works for me. When I receive the prescription (30 mls.), I split it into four small plastic bottles and put 7 mls. in each and freeze them (that leaves me with two doses in the original bottle). The day before each weekly dosing schedule begins, I thaw one of the 7 ml. bottles in the refrigerator. Each day I use a syringe to draw up 1 ml. for that day's dose. My vet furnished the small plastic bottles for free. Prior to getting the Interferon from Pet Health Pharmacy, I used a local (much more expensive!) pharmacy that dispensed it in individual dose syringes. Their instructions were to keep it frozen until ready to use, then thaw out a week's worth (seven syringes) at a time in the refrigerator. Each pharmacy seems to have a slightly different way of dealing with Interferon. I don't know why Island Pharmacy says not to freeze it once it's diluted as that contradicts what the two pharmacies I've dealt with have said to do. I hope this helps.
