[Felvtalk] Interferon Alpha,

[Lance]

You’re welcome. I only wish I could help more.

30ml of interferon alpha costs me about $45 in the US. That includes shipping, I think. 

How is the tomcat’s anemia? Did the vet run new blood work to see if his feeling better correlates to a rise in red blood cell values?

Interferon alpha could be expensive over the long run, just because you (or the new owner) would be buying it monthly. If I was in your situation (particularly being in Europe), and my cat had presented with anemia, I would look into Virbagen Omega instead. This drug is available in France, so it seems like it should be available throughout western and central Europe. 

Virbagen Omega is made for cats, and according to the literature we have, it makes a difference in survival time. Interferon alpha is a human drug, and the only evidence we have that it helps is anecdotal, not scientific. I’m not saying it doesn’t help. I just lost my FeLV+ girl, Ember, who had the virus for a minimum of eight years, and she did very well. I used interferon alpha on her. But, Virbagen Omega is not available here, and it costs a lot of money to get it sent over, so we used what was available.

Bottom line: I’m encouraging you to see if you can get Virbagen Omega in the Netherlands. If you can, and if the price-to-dose isn’t prohibitive, it would seem (according to what the literature says) that you would be better off giving the tomcat the limited number of doses of Virbagen Omega as opposed to keeping him on interferon alpha from here on out. But you (and the new owner) must do what feels right and what makes sense. 

If your vet is uncertain about interferon alpha and unfamiliar with Virbagen Omega, I would call around to find someone who has more experience. At the least, you could consult with them and get a “second opinion”. 

Best regards,

Lance

Talked to my vet this afternoon and he was not that positive about using interferon. Wallie seems to be doing right now he is eating a lot and is feelling much better than when I let him in. The vet prescribed him antibiotics and a prednisone treatment. If necessary will give him this interferom as well,

It will be expensive, though it should be somewhat cheaper than it is for Americans (we need it flown overseas, overnight. VO is not given all the time. Usually, the doses are given over several weeks’ time, then the drug is discontinued.

>>  I am new to your forum. 2 weeks ago a sweet tomcat decided that he wanted to join our group of 6 cats. Since umber 7 seemed a bit too much I found him a new owner but before given her this lovely guy. I went for a check up at the vet. He saw that he suffered from amnesia and tested him on feline leukemia and unfortunately this test turned out positive. As he is doing much better now than 2 weeks ago. He gained a  lot of weight and starts playing again I want to try to keep him healthy as long as possible. Looking for medicatons I landed on your very informational website. I think I want to start by giving him interferon alpha but this is very expensive in my country.
