Compounded Sildenafil (Viagra, Revatio) For Dogs, Cats & Other Pet Animals

Sildenafil is a vasodilator medication used animals and humans. It is used in animals to help a variety of conditions. It can be used to help reduce cough and other signs associated with elevated pressure in the lungs (pulmonary hypertension). It can also be used to treat high blood pressure and post-surgical conditions. It is important to remember that even though the medication takes effect within as little as 1-2 hours after being given, the true benefits of the medication to your animal’s health may not be seen outwardly. It may take 1-2 days of taking this medication for you to see an improvement in your animal’s condition. Sildenafil does require a prescription from your veterinarian in order to be dispensed. You and your veterinarian should discuss if this is the best option for your pet.

Sildenafil is given orally and can be compounded to the desired strength and flavor that best suits your patient/pet. We compound this medication into suspensions and capsules. This medication is best given with or without food. If the patient vomits after receiving the dose on an empty stomach, the next dose should be given with food to decrease GI upset. If you miss a dose do not double up on the medication. Wait until the next dose is due and follow the normal dosing schedule as directed. You and your veterinarian should discuss if this is the best option for your pet.

Common side effects of sildenafil include flushing/redness of the skin especially in the groin region, vomiting, and lack of appetite. If symptoms worsen or not resolve contact your veterinarian. Overdoses of this medication can be serious. If you suspect an overdose, contact your veterinarian or poison control.
