Sildenafil Used for Canines: A Surprisingly Effective Cure for Pulmonary Hypertension In Canines

Sildenafil can have many uses but when it is not being used to improve a man’s sex life, it can be used to cure dogs and cats. This may come as both a surprise and a farfetched notion but it holds true. Sildenafil is used in canines, dogs, and cats, with problems with their blood pressure in the lungs and heart. This problem is actually quite common and most people hardly notice this and the frequency with which it is being diagnosed is also rising. This is not because it is becoming more of a problem but because now vets are becoming aware of its existence and potential challenges.

Pulmonary hypertension takes root when an unusually high blood pressure is in the arteries of the lungs thus forcing the right chambers of the heart to labor more than they should keep things normal. The vet will tell you that your dog or cat has right-side heart failure. There are other scientific terms for the condition. It is essentially caused by blockages of blood flow through the lungs. Some common symptoms you can look out for to determine whether your pet has pulmonary hypertension include lethargy, shortness of breath, and fainting.

Sildenafil, when administered to pets that exhibit these symptoms, improves their overall energy and they are eager to play. You will know when your dog is happy. Research that has been conducted on human beings establishes that it works in around 60 minutes after consumption. According to the American Veterinary Medical Association, Viagra can be used to treat some rare heart diseases in addition to PAH. When Viagra is introduced into a dog’s body it dilates the blood vessels to allow easier flow of blood to the lungs and heart.

Sildenafil is not authorized for use on pets but has been used extensively by veterinarians who want to help your dog or cat overcome PH. A special mention of the fact that you should not administer Viagra to your pet without the authorization of a vet is warranted.

Viagra for Pulmonary Hypertension Dose in Dogs

When you take your dog to the veterinarian and he gets diagnosed with pulmonary hypertension, he will recommend a dose of Viagra (1 mg/1kg) if he deems it the best possible way to handle the condition. When the vet prescribes the Viagra to be taken, you should follow the dose exactly as prescribed. If you do forget to administer a dose of sildenafil, give your pet the next dose immediately you remember to do so. You can also administer this dose if it is not too far from the next scheduled dose or return to the prescribed schedule. When you miss a dose, do not give double the amount to make up ground. That will count as an overdose that can be catastrophic to your pet.

How Long Can a Dog Live With Pulmonary Hypertension

Usually, when a dog is diagnosed with pulmonary hypertension, they are usually harboring an underlying condition. When you want to know how long a dog will last, you have to take into account the underlying health conditions that may have caused the incidence of pulmonary hypertension in the first place.

In the past, when a vet determined that a dog had PH, it was almost certain that the dog did not have much longer time left to live. However, with more research leading to discoveries in the medical field, the prognosis of PH is no longer as grave a condition as it was before. This is to thank largely in part to the availability of sildenafil. The sildenafil makes life comfortable for most dogs and some have lived on for up to 2 years. It should be noted that this determination does not signify the whole picture since worse conditions lead to shorter lives.
