Felinized anti-NGF monoclonal antibodyProduct-specific clinical reference

Updated October 16, 2026 · Sources and review status below

For veterinarians and veterinary staff. Product-label information is distinct from extra-label clinical practice. This is not a complete prescribing formulary or an automated interaction screen. Verify the current label, exact formulation, patient and species-specific clinical reference before use. Independent veterinary/pharmacy review remains pending.

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

Approval and evidence apply to the named product, species, route and indication. An extra-label use requires its own prescribing assessment; a human indication is not an animal approval.

SAFETY REFERENCE · PRODUCT & SPECIES SPECIFIC

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.

Dosing & administration

Verify the source before prescribing. The regimens below summarize selected veterinary product labels, not every accepted veterinary use. They are not automatic substitutions between brands or formulations. Renal/hepatic disease, concurrent therapy, age, indication and clinical response can require a different plan.
