Elura (Capromorelin) for Cats: Appetite Stimulant & Weight Management

This information is for educational purposes only. Never give your pet any medication without your veterinarian's guidance. Dosing, frequency, and safety depend on your pet's specific health profile.

Elura is a prescription oral liquid for cats. Its active ingredient, capromorelin, is a ghrelin receptor agonist. Ghrelin is a hormone involved in hunger signaling, so this medication is designed to help some cats eat better and gain or maintain body weight under your vet’s supervision.

In the United States, Elura is FDA-approved to manage unintended weight loss in cats with chronic kidney disease (CKD). That matters because many cats with CKD lose weight gradually, even before the disease is fully recognized. Weight loss can affect strength, muscle condition, and day-to-day quality of life.

Elura is not a cure for kidney disease, and it is not the right fit for every cat with a poor appetite. Instead, it is one tool your vet may use alongside other options such as a kidney-supportive diet, nausea control, hydration support, blood pressure management, and treatment of other problems like dental pain or constipation.

Elura is primarily used to help cats with CKD-related weight loss. In the FDA field study, cats receiving Elura once daily for 56 days had a statistically significant improvement in body weight compared with control cats. The least-squares mean body-weight change by Day 55 was +5.2% in the Elura group versus -1.6% in the control group.

Your vet may consider Elura when a cat with kidney disease is eating poorly, losing weight, or struggling to maintain muscle and body condition. It can be especially helpful when the goal is to support calorie intake while your vet also addresses the underlying reasons appetite has dropped.

It is important to keep expectations realistic. Elura does not replace a full workup for weight loss. Cats may stop eating because of nausea, mouth pain, pancreatitis, constipation, hyperthyroidism, diabetes, cancer, stress, or progression of kidney disease. If your cat is not eating, your vet will usually want to identify those factors rather than relying on an appetite stimulant alone.

Elura is labeled for cats at 2 mg/kg by mouth once daily, which corresponds to 0.1 mL/kg of the 20 mg/mL oral solution. It is given directly into the mouth using the supplied dosing syringe. In the approval study, pet parents were instructed to keep the cat’s normal feeding schedule and, if a meal was routinely offered, to offer it about 30 minutes after dosing.

The dose is based on your cat’s body weight, so your vet may recheck weight regularly and confirm the correct volume. Do not change the dose on your own. If your cat spits out part of the medication, drools heavily, or vomits after dosing, call your vet for guidance on whether to repeat the dose.

Elura should only be used exactly as prescribed. The label notes that safety has not been evaluated in cats younger than 5 months, or in cats that are pregnant, lactating, or intended for breeding. Your vet may also use extra caution in cats with heart disease, severe dehydration, liver dysfunction, diabetes risk, or a history that suggests acromegaly.

The most commonly reported side effects in the field study were vomiting, hypersalivation, inappetence, behavior change, lethargy, diarrhea, and dehydration. Hypersalivation often happened around dosing and generally resolved within a few minutes. Some cats also disliked the taste or became harder to medicate over time.

The label also notes that Elura can cause temporary decreases in heart rate and blood pressure for up to about 4 hours after dosing. Because of that, your vet may be more cautious if your cat has known heart disease, weakness, faintness, or poor hydration. Elura may also increase blood glucose for several hours after dosing, so it may not be appropriate for cats with current or past diabetes.

Call your vet promptly if you notice repeated vomiting, severe drooling, marked lethargy, wobbliness, collapse, refusal to eat, or signs that kidney disease is worsening. Seek urgent veterinary care if your cat seems weak, cannot stand, has trouble breathing, or stops eating altogether. Cats can develop serious complications from not eating, including hepatic lipidosis.

The published Elura label does not list a formal drug-interaction section, so there is not a long, well-defined interaction list for pet parents to follow at home. That said, lack of a listed interaction does not mean every combination is proven safe. Your vet still needs a full medication list, including prescription drugs, supplements, probiotics, and over-the-counter products.

This medication deserves extra discussion if your cat is taking drugs related to blood pressure, heart rate, diabetes management, or liver metabolism, because Elura can temporarily lower heart rate and blood pressure and may raise blood glucose after dosing. Cats with CKD are often on several medications at once, such as anti-nausea drugs, phosphate binders, antihypertensives, potassium supplements, or fluids, so your vet may want to monitor response closely.

Tell your vet if your cat is taking medications for hyperthyroidism, hypertension, heart disease, diabetes, or liver disease, or if your cat has had unusual reactions to appetite stimulants before. If another medication seems to worsen drooling, vomiting, sedation, or appetite changes after Elura is started, contact your vet before making any changes.
