Solensia, the Zoetis brand name for frunevetmab, is an FDA-approved monoclonal antibody injection used by veterinarians to control osteoarthritis pain in cats. A veterinary professional gives the prescription medication beneath the skin once each month, using one or two single-use vials based on the cat’s weight. U.S. owners commonly encounter medication quotes near $75 for a lighter cat and $115 for a cat above 15.4 pounds, before separate examination or administration charges.

How Much Does Solensia Injection Cost?

A realistic planning range is about $75 to $175 (at $30 per hour, earning that amount would take about 2.5 to 5.8 hours of work, before taxes) per monthly visit as of July 2026. The invoice may combine the Solensia vial, injection service, and brief clinical review, or show each charge separately. The amount paid changes with vial count, local veterinary pricing, examination requirements, insurance terms, and the number of appointments completed during the year.

Solensia treatment is billed per veterinary visit rather than as a home prescription filled for several months. The largest medication modifier is whether the labeled weight band requires one vial or two. Provider fees, diagnostic services, claim deductibles, and pre-existing-condition exclusions can change the owner’s final expense.

TL;DR: A year of monthly Solensia injections can place the medication portion near $900 to $1,380 using published one-vial and two-vial figures, before added clinic services.

Important numbers

• One-vial reference for cats under 15.4 pounds: $75 (about 2.5 hours of work at $30 per hour) per injection
• Two-vial reference for cats above 15.4 pounds: $115 per injection
• Medication-only yearly estimate: $900 to $1,380
• Broader U.S. planning range: $75 to $175 per month
• Labeled schedule: one injection each month

A worked monthly total

Consider a cat weighing less than 15.4 pounds whose clinic uses the published $75 medication estimate. Assume the practice adds a $25 (about 50 minutes at $30 per hour) technician appointment charge. The sample visit contains a $75 injection line and a $25 service line, producing a monthly total of $100. Twelve visits at $100 each produce an annual total of $1,200.

This arithmetic shows why owners should ask whether a quoted injection figure is an all-in visit price. A clinic quoting $100 with administration included and another quoting $75 plus a $25 service charge produce the same total. A separate doctor examination would raise that month’s bill. Diagnostic imaging, blood testing, supplements, prescription food, transportation, and care for unrelated conditions are excluded from this worked example.

The yearly figure also assumes 12 completed appointments. Solensia is labeled for administration once a month, so a calendar with 12 doses turns the cited $75 medication figure into $900 before clinic fees. The same multiplication at $115 produces $1,380 for the medication portion of a two-vial schedule.

Cat weight and vial count

The most repeated U.S. consumer figures available through July 2026 are about $75 for cats below 15.4 pounds and $115 for cats above that weight. An August 2024 cost report cites those figures and identifies location, clinic type, labor, and dose as pricing drivers. These figures support budgeting, but they do not form a national veterinary fee schedule.

The weight threshold matters because the U.S. label instructs veterinarians to administer the full contents of one or two vials according to body weight. The current federal drug label states that Solensia contains 7 mg/mL and is given subcutaneously once a month. Cats in the higher labeled weight band receive two vials in one dose, giving the clinic a direct medication-cost reason to charge more.

Cat and billing situation	Planning amount	Yearly medication math
Under 15.4 pounds, one-vial reference	$75 per month	$75 × 12 = $900
Above 15.4 pounds, two-vial reference	$115 per month	$115 × 12 = $1,380
Broader reported U.S. visit band	$75 to $175	$900 to $2,100

The broader $75 to $175 band can reflect regional and practice-level differences, including how the clinic handles administration. It should not replace a written quote. Owners comparing veterinary hospitals should request the vial count, medication charge, injection fee, examination requirement, and full amount due at each monthly visit.

What you’re actually buying

Solensia is frunevetmab, a feline monoclonal antibody supplied by Zoetis and approved by the FDA for controlling pain associated with osteoarthritis in cats. It targets nerve growth factor, a protein involved in pain signaling. A veterinarian administers the medication beneath the skin during a clinic visit. Solensia is not an oral drug, nutritional supplement, joint diet, home exercise program, or one-time procedure. It forms part of recurring veterinary care, with continued treatment decisions based on the cat’s diagnosis, health record, mobility, response, and any reported reaction.

The manufacturer’s single-use vial specifications list a 7 mg/mL solution supplied in a 1 mL vial. That packaging connects body weight directly to billing because the labeled dose uses the full contents of one or two vials. An oral prescription may be dispensed for home use, but Solensia remains clinic-administered. Mobility aids such as low-entry litter boxes, ramps, and nonslip flooring may support a cat’s daily routine, yet they do not replace a veterinarian’s diagnosis or prescription.

The FDA approved Solensia on January 13, 2022. The approval covers osteoarthritis pain control in cats. Questions about candidacy, other health conditions, medication history, pregnancy exposure, or new symptoms belong with the prescribing veterinarian.

What the clinic bill includes

A Solensia invoice can contain the medication, the work of the veterinary professional administering it, and the clinical review attached to the appointment. Some hospitals publish one combined charge. Others list separate medication and injection lines. A practice may permit a technician visit after the veterinarian has established the diagnosis and treatment plan, or it may require periodic doctor examinations under its medical procedures and state practice rules.

The first appointment can cost more than a repeat injection because the veterinarian may review gait, jumping behavior, grooming, litter-box use, muscle condition, and pain responses. Federal feline osteoarthritis guidance describes diagnosis through veterinary evaluation and identifies Solensia as an approved monoclonal antibody injection. That guidance does not set retail clinic charges.

Ask for four figures in writing. These are the medication charge, administration charge, required examination fee, and full amount due on a routine injection date. Also ask how the practice bills a cat that moves into the two-vial weight band. A bundled quote can be simpler, but an itemized quote makes later changes easier to identify.

Related veterinary services may appear on separate dates. Published coverage of cat blood-work charges can help owners frame questions when laboratory testing is ordered for the cat’s wider health picture.

Fees that raise the bill

Hidden-cost callout A monthly quote near $75 to $115 may exclude a provider fee, examination, laboratory testing, imaging, pre-visit medication, or a missed-appointment charge. A broader visit band reaching $175 leaves room for some practice-level additions, but owners should not assume that every service is included.

An examination is the clearest added line. A new patient, a cat with a changed medical history, or an animal returning after a long gap may need a veterinarian visit before another injection is given. Blood work and imaging are separate clinical decisions rather than automatic Solensia requirements. They may be ordered to investigate other causes of reduced movement or to review health conditions that affect the treatment plan.

Transportation also affects the household total. A cat that becomes distressed in a carrier may need a longer appointment, prescribed pre-visit medication, or a mobile veterinarian. Those expenses are not part of the vial price. Owners comparing this treatment with a canine monthly injection can review the billing structure in the Librela injection cost article, but the drugs, species, doses, and clinic charges are different.

Missed appointments can create another expense without delivering treatment. A practice may charge for late cancellation under its own policy. Request that rule before scheduling a year of monthly visits, especially when work hours, travel, weather, or carrier stress make attendance harder.

Real payment cases

Budget case. A lighter cat receives one vial, and the clinic’s $75 quote includes administration. Twelve completed appointments produce $900 in medication visits. The main driver is vial count. This case excludes an initial examination and any unrelated care.

Higher-weight case. A cat above 15.4 pounds receives two vials at the cited $115 figure. Twelve injections produce $1,380. The difference between the two cited yearly totals is $480, calculated as $1,380 minus $900. That gap comes from published weight-linked figures, not from a claim that every veterinary clinic marks up two vials in the same way.

Insurance case. An owner pays a $115 clinic charge at checkout. The policy has a remaining deductible, so the first claim receives no repayment. Later eligible claims may be reimbursed at the policy’s stated percentage after exclusions and limits are applied. The owner still needs enough cash or credit to cover the full visit before the insurer processes the claim.

These cases isolate different cost triggers. The first reflects a bundled one-vial visit. The second reflects weight-based medication use. The third reflects claim timing and policy design. They are planning models rather than records of named customers.

Insurance vs self-pay

Pet insurance may cover Solensia when osteoarthritis treatment falls within an eligible accident-and-illness policy and the condition was not excluded. Coverage can still be reduced by the deductible, reimbursement percentage, annual limit, examination-fee rules, and waiting period. Arthritis documented before the policy became active may be classified as pre-existing and excluded.

The owner commonly pays the veterinary clinic first and submits a claim afterward. That creates a cash-flow difference between insured expense and checkout expense. A policy paying part of an eligible claim does not change the clinic’s invoice. It changes the amount retained by the owner after reimbursement. Wellness plans should be checked separately because they may cover routine care without paying for chronic-condition medication.

Frequency drives the annual total. The original FDA approval record identifies the labeled once-monthly dose and weight-based administration. At $75 per dose, completing 12 months rather than six adds $450, since six extra injections multiplied by $75 equals $450. At $115, six extra doses add $690.

Owners should read the declarations page and exclusions before relying on repayment. A veterinarian decides the medical schedule. An insurer decides whether a submitted charge meets the contract.

Who this cost makes sense for

The payment decision belongs beside the veterinarian’s clinical plan. A monthly injection creates a recurring obligation, so the household should review clinic access, weight-based pricing, treatment response, and insurance status before treating one appointment as the full financial picture.

Makes sense if

• The cat has a veterinary diagnosis of osteoarthritis pain.
• Monthly clinic visits are workable for the cat and owner.
• The owner can fund the full visit before any insurance repayment.
• The clinic provides a clear one-vial or two-vial quote.
• The owner can track mobility and report changes.

Doesn’t make sense if

• The cat has not received a veterinary evaluation.
• Monthly handling creates severe, unmanaged distress.
• The recurring charge displaces other necessary veterinary care.
• The policy excludes arthritis as a pre-existing condition.
• Follow-up access is poor after a health change.

What we verified

• Checked the once-monthly administration information for veterinary delivery of the injection.
• Confirmed the federal adverse-event reporting context, which does not by itself prove that a reported event was caused by Solensia.
• Cross-referenced the March 2025 clinic estimate against the broader consumer figures.
• Verified the related monthly injection billing model without treating canine pricing as a Solensia quote.

Article Highlights

• Published U.S. references place Solensia near $75 for a lighter cat and $115 for a cat above 15.4 pounds.
• Twelve medication-only visits at those figures equal $900 to $1,380.
• A two-vial dose can raise the medication line.
• Exams, administration, testing, transportation, and pre-visit medication may sit outside the quoted injection figure.
• Insurance repayment depends on the deductible, reimbursement rate, limits, and pre-existing-condition language.
• Request an itemized monthly quote before projecting the yearly expense.

Answers to Common Questions

How much is one Solensia injection?

Published U.S. references commonly cite about $75 for cats under 15.4 pounds and $115 for cats above that weight. Clinic totals may differ.

How much does a year of Solensia cost?

Using 12 monthly doses, the medication portion is about $900 at $75 per dose or $1,380 at $115 per dose. Added clinic services raise the total.

Why does a heavier cat cost more?

The label assigns one or two full vials by body-weight range. A cat in the higher band receives two vials during one monthly dose.

Does pet insurance pay for Solensia?

Some accident-and-illness policies may reimburse eligible treatment. Deductibles, waiting periods, annual limits, examination-fee rules, and pre-existing-condition exclusions can reduce or block payment.

Can Solensia be given at home?

The U.S. product is prescribed and administered by veterinary professionals. Owners should follow the prescribing clinic’s instructions rather than plan on home administration.
