Zenrelia
Tractor Supply proudly carries Zenrelia, a prescription option for dog skin and allergy relief, which targets the itching and inflammation that cause constant scratching. The medication is known for controlling the symptoms tied to skin allergies, which gives irritated skin a chance to recover. Learn more about how Zenrelia works and find out what to know before your dog starts it, along with the tablet options we have in stock.
The History Behind Zenrelia
Skin allergies can put dogs in a frustrating loop. The itch leads to scratching, the scratching irritates the skin and the irritation feeds the problem even further. Zenrelia is a prescription medication built to interrupt that loop, working from the inside to control the itching and inflammation connected to skin allergies and promote healing.
Made by Elanco Animal Health, a trusted leader in the animal health industry, Zenrelia is made for dogs older than 12 months and is available with a prescription from your veterinarian. Because it controls both the itching and the inflammation that comes with skin allergies, it fits dogs dealing with ongoing or seasonal skin allergies instead of a passing irritation.
About Our Zenrelia Selection
Zenrelia comes as a single prescription tablet, which is administered orally to combat skin and allergy conditions. It is meant for dogs with chronic symptoms and aims to control itching and inflammation. The veterinarian decides the dose based on the dog's overall health, which will be reflected in the prescription order, along with instructions to follow. Your veterinarian must also confirm your dog’s vaccination status, since the timing of certain shots has to line up with the medication.
Please read the following information carefully about our Zenrelia dog prescriptions:

Zenrelia Warnings and Side Effects
WARNING: INADEQUATE IMMUNE RESPONSE TO VACCINES. Based on results of the vaccine response study, dogs receiving Zenrelia are at risk of an inadequate immune response to vaccines. Discontinue Zenrelia for at least 28 days to 3 months prior to vaccination and withhold Zenrelia for at least 28 days after vaccination. Dogs should be up to date on vaccinations prior to starting Zenrelia. Do not use in dogs less than 12 months old or dogs with a serious infection.
Dogs should be monitored for infections because Zenrelia may increase the chances of developing one. Neoplastic conditions (benign and malignant) were observed during clinical studies. The most common side effects were vomiting, diarrhea and tiredness. Zenrelia has not been tested in dogs used for breeding, pregnant or lactating dogs and has not been evaluated in combination with glucocorticoids, cyclosporine or other immunosuppressive drugs.
