If you are arranging US delivery from Canada, check the selected listing, prescription details, and contact information carefully before placing the prescription order.
Cardalis Price and Available Options
The current listed price should be reviewed together with the selected tablet strength, total quantity, and any pack-size choices shown on the product page. Different strengths may be listed separately, so compare the exact presentation your veterinarian prescribed rather than choosing by tablet count alone.
Cardalis cost without insurance is most useful when you compare the same strength and quantity across available listings. A lower tablet count can appear less expensive upfront, while a larger quantity may change the per-tablet calculation. The product page should be your reference for the current listed amount, not older search results or general estimates.
Quick tip: Match the strength first, then compare quantity and checkout details.
For a veterinary heart medicine, small differences in strength matter. Cardalis 20 mg/2.5 mg, Cardalis 40 mg/5 mg, and Cardalis 80 mg/10 mg are not interchangeable unless your veterinarian changes the plan. The numbers refer to the active ingredients in each tablet, so the selected option should mirror the written prescription.
If you are comparing Cardalis cash-pay options, keep your dog’s current weight, prescribed strength, and refill timing nearby. Those details help you review the listing without guessing whether the selected product fits the treatment plan. Do not split, substitute, or combine strengths unless your veterinarian specifically instructs you to do so.
How to Buy Cardalis Online
To buy Cardalis online, select the prescribed strength and quantity, enter the required order details, and keep your veterinarian’s information available in case it is needed. This is a prescription veterinary medicine, and prescription details may be checked with the prescriber when needed.
The safest order path starts with the product your veterinarian named. Confirm the brand, active ingredients, strength ratio, and tablet form before completing checkout. If your dog is already taking other heart medicines, the order details should still match the current veterinary plan rather than an older refill label.
Supporting documents may be requested for some prescription orders. Having the clinic name, phone number, dog’s name, and current directions available can reduce back-and-forth if information must be confirmed. This practical step is especially important when the order is time-sensitive or the dog’s heart condition is being actively monitored.
Some customers compare cross-border access or cash-pay ordering when it fits their prescription and applicable rules. The product listing is where you should review the selected presentation, current availability signals, and any checkout prompts before finalizing the order.
Chewable Tablet Strengths and Selection
Cardalis tablets for dogs are chewable tablets that combine benazepril and spironolactone. Benazepril is an angiotensin-converting enzyme inhibitor, often called an ACE inhibitor, which affects blood-vessel tone and fluid-regulating hormones. Spironolactone is an aldosterone antagonist, a medicine that acts on aldosterone-related salt and water balance.
This benazepril spironolactone combination for dogs is prescribed by veterinarians for specific heart-failure situations. The chewable form can be easier for some dogs than a standard tablet, but it is still a medication. Store it out of reach of pets and children, and follow the dosing directions printed on the veterinary label.
| Strength | Active ingredient ratio | What to check before ordering |
|---|---|---|
| Cardalis 20 mg/2.5 mg | Spironolactone 20 mg and benazepril hydrochloride 2.5 mg | Confirm the smallest listed strength matches the prescription. |
| Cardalis 40 mg/5 mg | Spironolactone 40 mg and benazepril hydrochloride 5 mg | Review the ratio and quantity before checkout. |
| Cardalis 80 mg/10 mg | Spironolactone 80 mg and benazepril hydrochloride 10 mg | Make sure the larger strength is the one prescribed. |
Do not rely only on the first number in the strength. Each tablet contains two active ingredients, and both numbers matter. If a label, invoice, or old refill uses a different format, ask the veterinary clinic to clarify the intended strength before ordering.
Quantity also matters. A 30-tablet supply and a larger refill may support the same daily directions, but they change how long the order lasts. Compare the selected quantity with the refill interval your veterinarian expects, especially if your dog’s dose may be reassessed after follow-up testing.
What This Heart Medicine Is Used For
Cardalis for dogs is used in veterinary care for the management of clinical signs of congestive heart failure in dogs, particularly when prescribed as part of a veterinarian-directed plan. Congestive heart failure, often shortened to CHF, means the heart is not moving blood efficiently enough and fluid-related symptoms may develop.
As a dog heart failure medication, it may be used with other therapies such as furosemide when the veterinarian considers that combination appropriate. Some dogs with heart valve disease may also receive other cardiac medicines. The exact plan depends on the diagnosis, examination findings, imaging, lab results, and response to treatment.
Cardalis is not the same as a general supplement, cough remedy, or routine senior-dog product. It is intended for dogs with a diagnosed heart condition. Before ordering, the most important product decision is not whether the medicine is popular; it is whether the listed strength and directions match the current veterinary prescription.
Why it matters: Heart medications can look similar online but work in different ways.
Administration, Storage and Handling Basics
Follow the veterinarian’s directions for when and how the chewable tablet should be given. Cardalis dosage for dogs is based on veterinary assessment and product labeling, so this page should not be used to calculate or change an individual dose. If your dog misses a dose or vomits after dosing, ask the clinic how to handle the next scheduled dose.
Because the tablets are chewable, some dogs may take them readily. Others may need the tablet offered with food if the veterinarian allows it. Do not crush, split, or mix tablets unless the clinic has said that method is suitable for your dog and the prescribed strength.
Store the medicine according to the product label and any directions on the package. Keep tablets in their original container when possible, protect them from moisture, and close the container after each use. Avoid leaving veterinary medicines in a hot car, near a sink, or where another pet could chew through packaging.
Travel requires a little planning. Bring enough tablets for the full trip, keep the prescription label with the medicine, and maintain a dosing schedule your veterinarian has approved. If your dog’s breathing rate, appetite, or energy level is being monitored, take the tracking notes or app records with you to the next appointment.
Safety, Side Effects and Monitoring
Cardalis side effects for dogs can include vomiting, diarrhea, reduced appetite, tiredness, or changes that suggest the heart condition is worsening. Some dogs may show subtle signs first, such as less interest in walks, restlessness at night, coughing, or a faster resting breathing rate. Contact the veterinarian promptly if new or concerning symptoms appear.
Serious concerns need urgent veterinary attention. Trouble breathing, collapse, severe weakness, persistent vomiting, or marked loss of appetite should not wait for a routine refill question. Heart-failure symptoms and medicine-related effects can overlap, so the clinic may need to assess breathing, hydration, blood pressure, kidney values, and electrolytes.
Benazepril and spironolactone can affect kidney function and potassium balance. Veterinarians may recommend bloodwork before and during treatment, especially in dogs with kidney disease, dehydration risk, or multiple cardiac medicines. Monitoring is not just a formality; it helps the clinic decide whether the current plan remains appropriate.
Cardalis should not be used in every dog. Veterinary labels note important restrictions for dogs with certain electrolyte problems, such as high potassium or low sodium, and for dogs with hypoadrenocorticism, also called Addison’s disease. It is also generally avoided in breeding, pregnant, or nursing dogs unless the veterinarian is following label-supported guidance.
Tell the clinic if your dog has kidney disease, liver disease, severe dehydration, a history of fainting, or recent changes in eating and drinking. These details can affect how the veterinarian evaluates the prescription. They also help you decide whether to pause and ask a question before ordering another refill.
Interactions and Medicines to Review
Before ordering a refill, review all medicines and supplements your dog takes. This includes furosemide, pimobendan, NSAIDs for pain or arthritis, potassium supplements, blood-pressure medicines, and any over-the-counter products. Even products that seem unrelated to the heart can affect kidney function, blood pressure, or electrolyte balance.
Cardalis is sometimes used alongside other heart medicines, but combinations should come from the veterinarian’s plan. For example, Vetmedin is the brand name for pimobendan, a different cardiac medicine with a different role. Cardalis and Vetmedin are not the same product, and one should not be substituted for the other at checkout.
Ask the veterinary clinic whether any lab tests or recheck visits are due before the next refill. Dogs with congestive heart failure often need ongoing monitoring because symptoms can change. Refill timing is a good moment to confirm weight, breathing trends, appetite, cough frequency, and any recent emergency visits.
If another prescriber adds a medicine, update the veterinarian managing the heart condition. That includes urgent-care visits, dental procedures, pain treatment, or changes to diuretics. A complete medication list helps reduce avoidable interaction risks and keeps the prescription order aligned with the current care plan.
Comparing Related Veterinary Options
If you are comparing heart-related products, focus on the diagnosis and active ingredients rather than product names alone. The Canine Heart Failure product list can help you review condition-related options that may appear in veterinary care.
For broader browsing, the Pet Medications collection organizes veterinary products in one place. Use those pages to compare categories, not to replace a veterinarian’s instructions. Heart medicines, diuretics, and supportive treatments can have different monitoring needs even when they are prescribed for the same dog.
When comparing alternatives, avoid switching based on tablet form or perceived convenience. Cardalis contains a specific combination of active ingredients. Any change to another cardiac medicine, another strength, or a separate-pill regimen should be directed by the veterinarian who knows the dog’s diagnosis and test results.

What does Cardalis do for a dog?
Cardalis combines benazepril and spironolactone in a chewable tablet for dogs. Veterinarians prescribe it for the management of clinical signs of congestive heart failure in certain dogs, often as part of a broader cardiac plan. Benazepril affects blood-vessel and hormone pathways, while spironolactone acts on aldosterone-related fluid and electrolyte balance. It should only be used for the dog named on the veterinary prescription.
How quickly does Cardalis work?
Response time can vary by dog, diagnosis, disease severity, and other medicines being used. Some monitoring goals, such as breathing comfort, appetite, cough, energy level, and resting respiratory rate, may be followed over days or weeks. Do not judge response by one symptom alone. If breathing worsens, fainting occurs, or severe weakness develops, seek veterinary help urgently rather than waiting for a scheduled follow-up.
What are the side effects of Cardalis in dogs?
Possible side effects include vomiting, diarrhea, reduced appetite, lethargy, weakness, or changes related to kidney function or electrolytes. Because dogs taking Cardalis often have heart disease, side effects and worsening heart symptoms can look similar. Report new coughing, breathing changes, collapse, persistent stomach upset, or unusual tiredness to the veterinarian. Bloodwork may be recommended to monitor kidney values and potassium.
Is Cardalis the same as Vetmedin for dogs?
No. Cardalis and Vetmedin are different veterinary heart medicines. Cardalis contains benazepril and spironolactone, while Vetmedin contains pimobendan. A veterinarian may prescribe one or both depending on the dog’s diagnosis and treatment plan, but they are not substitutes at checkout. Always match the product, strength, and directions to the current veterinary prescription.
What should I ask my veterinarian before starting Cardalis?
Ask which strength was prescribed, how often it should be given, whether it should be taken with food, and what to do if a dose is missed or vomited. It is also useful to ask which symptoms require urgent care, when bloodwork should be repeated, and whether other medicines or supplements need to be changed. Bring a current medication list to every heart-related visit.
