Solensia for Cats

Most cats show pain improvement within 7 days, with full effect by the second monthly dose.

Yes — cats don't tolerate long-term NSAIDs well (kidney risk). Solensia targets pain at the source without the kidney concerns. It's a major step forward for chronic feline arthritis pain.

Monthly injection at your vet. Some cats respond to a slightly extended interval after the initial doses.

Solensia must be administered by a vet (it's an injection). RexVet can review whether Solensia is appropriate and refer to an in-person clinic for the injection.

Signs include: reluctance to jump up or down, stiffness after rest, hiding more, less grooming, less litter box use (if box is high), aggression when touched. A vet exam confirms.

Solensia is a monthly injection given at a veterinary clinic, so there is no single price: each clinic sets its own fee, usually as part of the visit, and it varies by region, by clinic and by the cat, because the dose is based on the cat's weight. Ask the clinic that will give the injection for a quote that includes the exam and any recheck, and expect it to be an ongoing monthly expense for as long as your cat stays on it.

No. Solensia is a prescription injection that federal law restricts to use by or on the order of a licensed veterinarian, and it is not sold for owners to give at home. The label calls for the contents of a single-use, refrigerated, preservative-free vial to be drawn into a syringe and injected immediately, with a specific warning about accidental self-injection. Vets administer it in the clinic. RexVet can discuss whether Solensia suits your cat and refer you to a local clinic for the injections.

Per the FDA label, Solensia (frunevetmab) is given by subcutaneous injection, under the skin, once a month by a veterinarian. The amount is chosen from a weight-range chart, drawn from one or more single-use vials into a syringe and given right away. Most cats show improvement within days of the first dose, and it can take more than one monthly injection to reach the full effect, so your vet will typically recheck after the first few doses.
