🚨 Red flag — call your vet now if: New persistent cough, weight loss, lumps, recurrent skin infections, or fever – these need a same-week vet visit, not a wait.
What you should actually do
- Standard chronic dose is once daily at 0.4-0.6 mg/kg (half the loading dose).
- Recheck CBC + chemistry every 6 months on chronic use.
- Modest infection risk (skin, ear, UTI) – report any new infection.
- No documented increase in cancer rate in long-term safety studies.
- Pair with omega-3 + medicated bathing to reduce overall steroid/JAK load.
The original FDA approval was based on a 16-week study, but Zoetis has since published 18-month and 7-year follow-up data showing stable efficacy and no new safety signals beyond what is on the label. The dogs at most risk for adverse events are those started on Apoquel with an undiagnosed pre-existing infection, an occult neoplasm, or an immune-compromising co-morbidity. That is why a vet exam and basic bloodwork before starting – and every 6 months on chronic therapy – is the standard of care.
If your dog has been on Apoquel for years and is doing well, there is no clinical reason to stop. If you want to reduce the total drug burden, the practical path is dose-minimization (try 0.4 mg/kg once daily instead of 0.6) plus an adjunct like Cytopoint, fatty acids, or a hypoallergenic elimination diet trial.
