- It is vital that pre- and post-treatment medications must be given to decrease the potential for severe systemic adverse reactions, including death, from mast cell degranulation.
- Formation of wounds, possibly extensive, is an intended and likely response to treatment with STELFONTA along with the associated swelling, bruising and pain; these wounds are expected to heal.

Accidental self-injection of STELFONTA® may cause severe wound formation. To decrease the risk of accidental self-injection, sedation of the dog may be necessary. In dogs, do not inject STELFONTA into subcutaneous mast cell tumors located above the elbow or hock. Formation of wounds, possibly extensive, is an intended and likely response to treatment with STELFONTA along with associated swelling, bruising and pain; these wounds are expected to heal. Appropriate pre- and post-treatment medications must be given, including a corticosteroid plus blocking agents for both H1 and H2 receptors, in order to decrease the potential for severe systemic adverse reactions, including death, from mast cell degranulation.

FOR PET OWNERS
Wear disposable gloves when cleaning the treated tumor site to avoid contact with any residual drug. Thoroughly wash your skin that comes in contact with the treated tumor site, wound, or wound discharge. Ensure your dog receives their prescribed medications to decrease the potential for severe, life-threatening adverse reactions. Monitor your dog during the healing process and contact your veterinarian if you notice excessive pain, lameness, tiredness, refusal to eat for more than one day, repeated vomiting or diarrhea, trouble breathing, changes to the treated tumor site (including increased or excessive swelling and bruising, extensive wound formation, increased irritation) or any other symptoms that concern you. For full prescribing information, contact Virbac at 1-800-338-3659 or view the Product Insert.
Discover what the STELFONTA® treatment journey has been like for pet owners
“After the treatment, she was miserable for a few days, but within a week, she bounced back to normal, doing big walks and going running”, explained Katja. “Lou’s just had her eighth birthday. Without treatment, she wouldn’t have survived or enjoyed such an active life.”
“We intend to share many more years together,” said Katja, “so I don’t hesitate to continue with treatment when necessary.”
Debra couldn’t be happier with the results of Sally’s treatment. “I’ve continued down this path because it’s not invasive,” explained Debra.
There’s always some initial discomfort, but as Debra explained, “they dry up really quickly within a couple of days and heal over.” Today, Sally is happy and as full of energy as an 11-year-old can be and Debra said Sally is still keen for walks and play. “If I pick up her lead, she’s all over me and ready to go.”
Dennis recalled how quiet Mariah became after diagnosis, “she knew things weren’t right”. But after the treatment, it didn’t take long for Mariah to get her energy back. “She was down for the first week and didn’t want to do anything. But then she perked up and, within a month, she got more energy. Now she’s bouncing all over the place and keeps up with our other dog perfectly,” said Dennis.
He also commented on the healing of the tumor site, noting “gradually the skin grew back again and now it’s completely gone. Not even a mark, a dent – nothing. Completely gone.”
Barney’s tumor was on his bottom – a tricky place to treat surgically. Wendy explained why the veterinarian’s recommended treatment was an easy choice for them. “They could have tried surgery but may not have got all the tumor because it was so close to the bowel. Plus, as an older dog, there’s always the risks with anesthetics”, explained Wendy.
“The vet gave Barney the first injection, but a few weeks later, he had to have a second one to get the last few spots around the edge,” said Wendy.
Today, Barney is doing well, and Wendy is happy with the result. “You wouldn’t know he had cancer a month ago.”
Piper was facing amputation to remove an MCT on her hind leg.
“That would have been devastating for Piper, who is such a high-energy dog,” explained Tammy. “Through treatment she was a bit more sleepy than usual, but within two weeks, she was back to her usual bouncy, bubbly self again.”
Tammy’s advice to fellow dog owners was simple. “I’d recommend it to anyone.”
Sammi was concerned Ruby would have to be put down after her vet confirmed there wasn’t enough skin on Ruby’s leg, where the MCT was detected, to be cut out. But after a local treatment injected into the tumor, it was an easy decision to treat another MCT that appeared just months afterwards.
“It was amazing to watch because within a day it turned black and the tumor died. All we did was leave it, and it was amazing,” said Sammi. The second MCT took longer to heal, but Sammi noted “at first, it was a deep hole, but now it’s just a shiny scar about the size of a 20-cent piece. I really believe that this was a great option for Ruby. Within days, she was recovering and up again. She did not even need anesthetics.”
Steve described how the wound where Shirley’s tumor used to be didn’t stop her from getting back to normal.
“Within a week of treatment, the lump became swollen and burst,” said Steve. “It smelt at first but within a week, she started coming good – even though the wound was there. It was amazing. Her recovery was incredible. She is now back to being a typical Staffy bullet – she’s nuts!”. Steve added that given the choice again, “we would definitely do this.”
Nase’s owner Leanne spotted the lump on the back of his leg and went to the vet, who recommended an injectable treatment.
The treatment started to work quickly, “the lump swelled up within an hour and started to go dark. The vet explained this meant the treatment was working,” explained Leanne.
The best thing for Leanne was how Nase seemed to have even more energy than before. “Within a month, he was actually better after the treatment than beforehand. He wasn’t as tired and got his appetite back.”
Daisy’s tumor was a lump that looked like a wart on her right leg.
Brigette explained she looked after the wound that formed after treatment. “Within a couple of hours, it started to go black and looked inflamed.”
“There was a bit of a smell, but not so bad that it bothered us,” explained Brigette. “It looked like a scab on top that started to fall away and left a clean crater.”
Today, you can hardly notice the tiny scar and Brigitte happily reported that “there’s no stopping Daisy now. The vet recommended this treatment because the alternative was limb amputation and I can’t imagine her quality of life, so this has been amazing. It’s prevented her from losing her leg.”
Boston had a lump on his side that grew so quickly. Jacqui took him to the vet to investigate it.
Jacqui said it was reassuring to be able to talk to her vet as the tumor site went through the stages of healing. “It went gloopy at first, but the vet reassured us that was meant to happen. Boston licked the open wound and even tore it a little bit. Again, our vet explained this was part of the healing process. Now a month and a half later, it’s just a small scar that you can hardly see and Boston’s like a new dog. He’d come up and say Hi, wag his tail and put his head in your lap. He gets excited and chases his ball and runs along the beach like his normal happy self.”
