50% less than the animal hospital pharmacy
My cat, Maximus, has feline herpes. The opthamologist at the animal hospital prescribed Famcilovir which was very expensive but I found it for half the price at VetRxDirect. The infection was cleared up in 10 days. It was a pleasure doing business with your staff who contacted the animal hospital, filled and shipped the medication within a couple of days. I highly recommend VetRxDirect to all my friends and pet owners.

Famciclovir: mixed results on feline upper resp
Trying this for the first time on a feline upper resp infection, getting mixed results - it seems to be effective on some aspects of the problem, but not others. Two days to go on Rx, so we'll see if the next 48 hrs (4 tabs) do the trick or not. If it doesn't, I CANNOT honestly say that Famciclovir "didn't work," all I CAN say is that my cat may have a resistance to it or have a different "bug" than this product is intended to treat.

It definitely reduces his flare ups and makes him a much happier cat. Thank you vetrxdirect for reminding me when to order so my kitty never runs out of medicine. -
Famciclovir saved Mama's life!
From UndisclosedComments about Famciclovir (Generic) 250mg TabletMama is FIV+ with stomatitis and has chronic upper respiratory infections. With famciclovir twice a day she is able to take a tiny dose of prednisone daily and is upper respiratory free. She is pain free, eats well and is very happy. Her coat went from greasy unkept to soft and silky. -
She's still taking them

A Life-Saver for Immunosuppressed Cats
From UndisclosedComments about Famciclovir (Generic)I have four cats, two of whom have regular herpes flares due to being immunosuppressed from long-term steroid treatment for IBD/IBS. The minute I notice sneezing or watery eyes, I intervene with Famciclovir, and every single time, it works to prevent the flare from becoming a full-fledged URI and/or eye infection. Without this drug to stop symptoms, I would be running a feline hospital all the time. I am so grateful that this is now a tool that cat owners can use for feline herpes flares.-

Two Bengals who are very grateful for Famciclovir . . . as much as cats are ever grateful for anything.

Seen it work wonders
From UndisclosedComments about Famciclovir (Generic)I have seen this drug help prevent terrible herpes eye infections when given at the first sign of redness. It can also help a great deal with very bad URIs in cats and kittens. And unlike antibiotics, you don't have to do a full course. Check with your vet as the recommended dosage has increased over the years, finding it to be more effective. -
