What Is Solensia for Cats?
Solensia (frunevetmab) is an FDA-approved monthly injection used to control pain associated with osteoarthritis (OA) in cats. Approved in 2022, it is the first monoclonal antibody medication cleared by the FDA for veterinary use in cats and remains the only FDA-approved treatment specifically designed for feline osteoarthritis pain. The injection is administered by a veterinarian once every four weeks and typically costs $75 to $115 per dose.

Unlike traditional pain medications such as NSAIDs, Solensia is a biologic protein rather than a chemical compound. This distinction makes it a unique option for cats, which are notoriously difficult to medicate with oral drugs and can be sensitive to many common pain relievers.

The information provided should not be used for the diagnosis or treatment of health problems in your pet. Always consult with a licensed veterinarian for advice about any medical concerns regarding your cat.
How Solensia Works
Solensia works by targeting and neutralizing nerve growth factor (NGF), a key protein involved in osteoarthritis pain signaling. When NGF is blocked, fewer pain signals travel to the cat's brain, resulting in reduced discomfort and improved mobility.
| Feature | Solensia | Traditional NSAIDs |
|---|---|---|
| Drug type | Monoclonal antibody (biologic protein) | Chemical compound |
| Pain target | Nerve growth factor (NGF) | Cyclooxygenase (COX) enzymes |
| Administration | Monthly injection at vet clinic | Oral (daily) |
| FDA approved for cats | Yes | Limited options |
Frunevetmab, the active ingredient, is a monoclonal antibody. This means it is a lab-engineered protein designed to attach to one specific target in the body. In cats with osteoarthritis, NGF contributes to joint pain and inflammation. By binding to NGF and preventing it from interacting with pain receptors, Solensia reduces the intensity of pain signals without relying on the anti-inflammatory pathways used by NSAIDs.
Because Solensia mimics the cat's own naturally produced antibodies, it is processed by the body differently than chemical-based drugs. The medication is broken down through normal protein degradation pathways rather than being metabolized by the liver or kidneys. This can be an important consideration for older cats with compromised organ function.
How Much Does Solensia Cost?
A single Solensia injection typically costs $75 to $115 per monthly dose. The total cost of a Solensia appointment may be higher when veterinary exam fees or administration charges are included. Over the course of a year, cat owners can expect to pay approximately $900 to $1,380 for the injections alone.
| Cost Factor | Estimated Cost |
|---|---|
| Solensia injection (per month) | $75 – $115 |
| Annual injection cost (12 months) | $900 – $1,380 |
| Veterinary exam fee (if applicable) | $50 – $75 |
| Total monthly cost with exam | $125 – $190 |
Factors That Affect Cost
Several variables influence what you will pay for Solensia each month:
- Cat's weight: Cats weighing 5.5 to 15.4 pounds require one vial per dose, while cats weighing 15.5 to 30.8 pounds need two vials, effectively doubling the medication cost.
- Geographic location: Veterinary pricing varies significantly by region. Urban clinics and veterinary hospitals tend to charge more than rural practices.
- Type of veterinary practice: Specialty clinics and animal hospitals often have higher fees than general practice clinics.
- Exam fees: Some veterinarians bundle the injection cost with a wellness check, while others charge separately for the office visit.
| Cat's Weight | Vials per Dose | Estimated Cost per Injection |
|---|---|---|
| 5.5 – 15.4 pounds | 1 vial | $75 – $85 |
| 15.5 – 30.8 pounds | 2 vials | $95 – $115 |
Does Pet Insurance Cover Solensia?
Some pet insurance plans may cover the cost of Solensia injections and related veterinary visits. Coverage depends on your specific policy and whether osteoarthritis is classified as a covered condition. It is best to check with your insurance provider before beginning treatment to understand your plan's reimbursement structure and any applicable deductibles or waiting periods.
Shop around for a veterinary practice that fits your budget. Prices for Solensia can vary considerably between clinics in the same area. Ask about package pricing for multiple monthly visits or whether your vet offers any loyalty discounts for ongoing treatments.
Side Effects of Solensia
Solensia is generally well tolerated by most cats. Clinical studies found that the medication provided long-acting pain relief with a low incidence of adverse reactions. However, like any medication, side effects can occur. Understanding what to watch for helps you respond quickly if your cat has a reaction.
| Side Effect | Frequency |
|---|---|
| Vomiting | Common |
| Pain at the injection site | Common |
| Diarrhea | Occasional |
| Scabs on the head and neck | Occasional |
| Itchy skin (pruritus) | Occasional |
| Dermatitis | Occasional |
| Hair loss | Rare |
| Lethargy | Rare |
Common Side Effects
The most frequently reported side effects in clinical studies were vomiting and injection site pain. These reactions are typically mild and tend to resolve on their own without medical intervention.
Some cats may develop scabs or skin irritation on the head and neck area. Itching and mild dermatitis have also been reported. Monitor your cat closely after each injection and note any changes in behavior or appearance.
When to Contact Your Veterinarian
Contact your veterinarian immediately if you observe any of the following after your cat receives a Solensia injection:
- Severe or persistent vomiting or diarrhea
- Signs of an allergic reaction, such as facial swelling, difficulty breathing, or hives
- Worsening pain or decreased mobility
- Significant skin lesions, sores, or excessive hair loss
- Lethargy or noticeable changes in behavior
Overdose Concerns
While Solensia is administered by a veterinarian (which reduces the risk of overdose), receiving more than the prescribed dose may increase the likelihood of side effects. Signs of an overdose can include vomiting, diarrhea, skin sores, itching, hair loss, and lethargy. If you suspect your cat has received too much medication, contact your veterinarian or an animal poison control center immediately.

Human Safety Considerations
Solensia is not approved for use in humans. Because it is administered in a veterinary clinic, the risk of accidental human exposure is low. However, pregnant or breastfeeding individuals, or those trying to conceive, should avoid handling the syringe. Accidental self-injection may cause hypersensitivity reactions. If accidental self-injection occurs, seek medical attention immediately and bring the product label with you.
How Solensia Is Administered
Solensia is given exclusively by a veterinarian as a subcutaneous (under the skin) injection. It is not available for at-home administration. Each appointment typically involves a brief assessment of your cat's pain levels, the injection itself, and a short monitoring period to observe your cat's response.
| Administration Detail | Information |
|---|---|
| Route | Subcutaneous injection |
| Administered by | Licensed veterinarian |
| Frequency | Every 4 weeks |
| Dosing basis | Cat's body weight |
| At-home use | Not available |
During each visit, your veterinarian will determine the appropriate dose based on your cat's current weight. The injection is quick, and most cats tolerate the process well. Your vet may also use each monthly appointment as an opportunity to evaluate your cat's overall health and adjust the treatment plan as needed.
What to Do If You Miss a Dose
If you miss a scheduled appointment, contact your veterinarian to reschedule as soon as possible. Maintaining a consistent four-week schedule helps ensure continuous pain relief. Your vet will advise you on the best timing for the next injection based on when the last dose was given.
Which Cats Should Not Receive Solensia
Solensia is not appropriate for every cat. Certain health conditions and life stages may make this medication unsuitable. Always provide your veterinarian with a complete medical history and a list of all current medications and supplements before starting treatment.
| Category | Recommendation |
|---|---|
| Known allergy to frunevetmab | Do not use |
| Breeding cats | Safety not established |
| Pregnant cats | Safety not established |
| Lactating cats | Safety not established |
| Kittens | Safety not established |
| Cats with chronic health conditions (e.g., kidney disease) | Discuss with veterinarian |
Cats with a known hypersensitivity to frunevetmab should not receive Solensia. The safe use of this medication has not been evaluated in breeding, pregnant, or lactating cats, nor in kittens. If your cat has other chronic health conditions such as kidney disease, your veterinarian will weigh the potential benefits against any risks before recommending treatment.
How Effective Is Solensia?
Clinical research and real-world experience from cat owners suggest that Solensia can significantly reduce osteoarthritis pain and improve quality of life. Results can vary between individual cats, with some responding faster than others.
| Metric | Result |
|---|---|
| Owners reporting pain improvement (3-month study) | 77% |
| Placebo group reporting improvement | 67% |
| Onset of relief | Days to weeks |
| Majority of owners reporting improvement | After 3 months of treatment |
In a three-month clinical study, 77% of cat owners whose pets received monthly Solensia injections reported improvement in signs of pain, compared to 67% of those whose cats received a placebo. Some cats experience noticeable improvement after just one injection, while others may require two to three monthly doses before the full benefits become apparent.
How Quickly Does Solensia Work?
The speed at which Solensia provides relief varies from cat to cat. Some owners notice changes within a few days of the first injection. For others, it may take several weeks of consistent monthly treatment before significant improvements are visible. Most veterinarians recommend committing to at least three months of treatment before evaluating whether the medication is working effectively for your cat.
Is Solensia Worth It?
Many cat owners report meaningful improvements in their cat's mobility, energy, and overall comfort after starting Solensia. Cats that previously struggled with jumping, climbing stairs, or playing have shown renewed activity levels. Because osteoarthritis is a progressive disease with no cure, ongoing pain management is essential for maintaining quality of life.
Discuss your cat's individual response to treatment and the ongoing monthly expense with your veterinarian to determine whether continuing Solensia is the right decision.
Signs Your Cat May Have Osteoarthritis
Osteoarthritis is a degenerative joint disease that causes cartilage to break down, leading to bone-on-bone friction, chronic pain, stiffness, and inflammation. It most commonly affects the hips, knees, elbows, ankles, and shoulders in older cats, though it can develop at any age following joint injury or trauma.
| Symptom | What to Look For |
|---|---|
| Decreased activity | Less movement, reluctance to play |
| Difficulty jumping | Avoiding furniture, countertops, or cat trees |
| Stiffness or limping | Especially noticeable after rest |
| Reluctance to use stairs | Hesitation going up or down |
| Behavioral changes | Irritability, aggression when touched |
| Grooming changes | Over-grooming painful areas or neglecting grooming |
| Appetite or weight changes | Eating less, losing weight |
| Swollen joints | Visible swelling or sensitivity to touch |
Cats are skilled at hiding pain, which means osteoarthritis often goes undiagnosed until the disease has progressed significantly. If you notice any of these symptoms, schedule a veterinary exam. Your vet may use X-rays, MRIs, or CT scans to confirm the diagnosis and determine which joints are affected.
Osteoarthritis cannot be cured, but early intervention can slow its progression and improve your cat's comfort. If your cat is showing even subtle changes in mobility or behavior, a veterinary evaluation is worthwhile.
How Solensia Is Stored
Solensia is stored and handled entirely by your veterinary clinic. There is no at-home storage required since the medication is only administered in a clinical setting.
| Storage Requirement | Specification |
|---|---|
| Temperature | Refrigerated at 35°F to 46°F (2°C to 8°C) |
| Light protection | Stored in original carton |
| Handling | Veterinary clinic only |
The medication must be kept refrigerated between 35°F and 46°F and stored in its original carton to protect it from light. Your veterinary team handles all aspects of storage and preparation, ensuring the medication maintains its efficacy and safety.
Frequently Asked Questions
Can I buy Solensia online?
Solensia is a prescription medication that is only available through a licensed veterinarian. While some online retailers may advertise the product, it is always safest to obtain it directly from your vet's office. The medication must be administered by a veterinary professional and cannot be given at home.
How long does my cat need to stay on Solensia?
Because osteoarthritis is a chronic, progressive condition, most cats benefit from ongoing monthly injections for as long as the medication is providing effective pain relief. Your veterinarian will periodically assess your cat's condition to determine whether continued treatment is appropriate.
