Prescribing overview
Solensia controls feline osteoarthritis pain by targeting nerve growth factor. Review the updated October 2026 client information before every injection.
Key prescribing checks
- Do not administer to cats with known hypersensitivity to frunevetmab.
- The label excludes breeding cats and pregnant or lactating queens because of potential reproductive and offspring risks.
- Review patient age, body weight and concurrent treatment against the complete label; a familiar osteoarthritis diagnosis does not settle every eligibility issue.
- Review and provide the Client Information Sheet before each injection. The FDA’s October 5, 2026 labeling update adds post-approval reports including severe skin reactions, neurologic and urinary signs, and cases ending in death or euthanasia. Spontaneous reports do not establish frequency or causality; investigate new signs and reassess continued treatment.
Uses by species

Contraindications & cautions
Contraindications identify circumstances where the source says a product should not be used. Precautions call for assessment or monitoring. Interactions identify combinations to review. They are distinct categories; this summary does not replace a full interaction check or the current product label.
Solensia
U.S. feline subcutaneous-injection label, updated October 2026.
Contraindications · when not to use
- Known frunevetmab hypersensitivity; breeding, pregnant or lactating cats.
Precautions & monitoring
- Younger/smaller cats and prolonged treatment have evaluation limits; review current client information before each injection.
Safety sources checked: . Selected label information; independent veterinary or veterinary-pharmacy review remains pending. A label for dogs, cats, horses or humans does not establish safety for another species.
Adverse effects
2026 postapproval reports include severe skin reactions, neurologic/urinary signs, anaphylaxis and death/euthanasia; reports cannot establish incidence or causation.
These are selected source-reported effects, not incidence estimates or an exhaustive list. Spontaneous postmarketing reports do not by themselves establish frequency or causality.
