Product Overview

"Sildenafil is available with a veterinarian prescription. It is often prescribed to treat lung and heart problems, including pulmonary hypertension.

Tablets are sold individually."
Sildenafil is a prescription drug that is regularly prescribed by veterinarians to treat heart and lung problems which include pulmonary hypertension.
For use in cats and dogs.
Sildenafil increases the blood pressure within the lung arteries. It is often prescribed for the treatment of pulmonary hypertension.
Pulmonary hypertension is abnormally high blood pressure within the lung arteries. This causes the right side of the heart to work too hard. Sildenafil relaxes the smooth muscle around the small blood vessels within the lungs, which decreases the heart's workload. This medication works to improve overall quality of life, tolerance to exercise, and energy levels of animals suffering from pulmonary hypertension.
The most frequently reported adverse reactions include:
  • Skin flushing
  • Skin reddening
  • Gastrointestinal upset
Sildenafil Citrate
Contact your closest emergency pet hospital.
  • Drug interactions can occur when Sildenafil is administered with rifampin, phenobarbital, itraconazole, ketoconazole, clarithromycin, erythromycin, and cimetidine.
  • Do not administer with drugs that can lower blood pressure, including hypotensive drugs, amlodipine, alpha-adrenergic blockers (including phenothiazines, phenoxybenzamine, and phentolamine), nitroprusside sodium, and nitrates.
  • Never administer to a human.
  • Only administer this medication to the animal it was prescribed to treat.
  • Keep away from animals and children.

I have a 10 year old dachshund with multiple health issues, including a heart condition. My long time and much trusted vet recommended this medication as a part of Lulu’s treatment plan. Lulu has been on sildenafil for over two months now and it has really helped. She will remain on this medicine for the remainder of her life. If your vet recommends this medication, please try it.

I have a dog who has a heart murmur. His medications can add up to a lot of money. Thank God someone referred Allivet to me, I now am saving money on my dogs prescriptions not to mention the ease of auto filling the prescriptions. Should I need to make a change, it is so easy (a click or two you are done).

When my dog was in Congestive Heart Failure, the vet did not have any Sidenafil to administer. I had to send my husband to rite aide with the prescription while the Vet waited with me. It cost $80 PER PILL. We bought five as the vet said he may not survive. He was rushed to a Vet Referral ICU who also did not have the med on hand but used the ones I bought until their pharmacy had it available. When he was discharged I bought it at Allivet for $0.36. This was two years ago, and my mini Dachshund is alive and well, to my Vets surprise.

This medicine is used for a condition called Megaesophogus. Our dog was very very ill, couldn't keep food down, kept regurgitating her food. This was a life saver. It was experimental and it turned out to work!

My 14-year-old Westie was diagnosed with Pulmonary Hypertension last year and was almost close to dying when we took her to an internist/emergency hospital. She was prescribed Sildenafil and Vetmdein, and six months later, her left side of her heart has reduced in size and has moved from an end-stage diagnose to moderate disease diagnosis. We also give her a taurine supplement and SerraPet, an enzyme that works for inflammation. She's on a 100% raw food diet and although she can't do the long walks anymore, she's still got some energy and her quality of life is still strong.

Researched the internet including Better Business Bureau for complaints. None found for product provision. My Jazzy will be on this medication for her entire life. I m a senior citizen I needed recurrent delivery. As a New Englander. I needed medication for her snowy days , every day. My son researched and we both found good reports on your pharmacy. I called. Allivet contacted my veterinarian and I had her first prescription within 5 days. Telephone contact was always courteous and helpful. Emails informed me of the status. I’m so pleased for a new customer. Thank you. Jazzy is a nationally certified pet therapy dog and has helped so many. Now your company has helped her

So easy to order. Allivet contacted my vet and the medication was shipped within a few days. Great pricing for sildenafil. I was paying $108 for a three month supply at a compounding pharmacy. I saved about $34 through Allivet for the same three month supply. Would recommend to other pet owners.

My dog needed these pills for his heart condition. They would have been unaffordable if I had to get them at my regular local pharmacy. If I didn't find Allivet, my dog would have had to go without these pills. They saved me a ton of money. Also, had no trouble with my order. They were ordered on a Tuesday, and they arrived on Friday. No problems at all.
