Zenrelia contains ilunocitinib, which works by selectively blocking Janus Kinase (JAK) enzymes, specifically JAK1, which are responsible for sending itch signals to the brain. By interrupting these pathways, it reduces the urge to scratch and calms skin redness without the systemic side effects of steroids. --- ### **Available Zenrelia Tablet Strengths:** - Zenrelia 4.8mg - 6.4mg - 8.5mg - 15mg **Available for purchase as a single tablet.** --- ### **Warnings:** Do not use: - In dogs with evidence of immune suppression - In dogs with progressive malignant neoplasia (cancer) - In dogs with known hypersensitivity to ilunocitinib or any of the excipients - In dogs under 12 months of age - In breeding, pregnant, or lactating dogs Use with caution in dogs with a history of recurrent infections.
