What is Sinu-Rite?

Sinu-Rite is a safe, non-addictive, natural remedy containing 100% homeopathic ingredients specially selected to relieve the symptoms of sinusitis in pets, including inflammation, discharge from the eyes and nose, congestion and discomfort. In addition to addressing those symptoms related to sinus infections, Sinu-Rite also reduces recovery time and strengthens your pet’s immune system to prevent recurring infections.

Presented in convenient tablet form, Sinu-Rite can be crushed, sprinkled on the tongue, or taken whole, and is easy to administer without fussing or fighting.

Sinu-Rite is also an excellent companion to homeopathic Respo-K™, as it relieves the symptoms of colds and respiratory infections in pets. Used together, Sinu-Rite and Respo-K can provide immediate symptomatic relief of sinus and respiratory infections, and improve your pet’s long-term sinus health and respiratory health!

The formula remains true to the full spectrum method of herbal extraction, ensuring the bioavailability and balance of all the active ingredients contained in the remedy. This manufacturing method also significantly reduces the likelihood of side effects and ensures that all active ingredients are in perfect balance.

All PetAlive products are manufactured in FDA-registered, GMP-certified facilities under the supervision of an expert team of herbalists, naturopaths, homeopaths and responsible pharmacists.

Sinus infections and pets

The sinuses are bony cavities in the skull that meet up with the nasal cavities and are prone to infection, especially after a cold or other upper respiratory tract infection. In cats and dogs, sinus infections may be caused by bacteria, fungi or viruses and are sometimes even associated with tooth abscesses. Sinusitis (inflammation of the sinuses) may also be caused by non-infectious ailments such as allergies.

Typical signs of a sinus infection are sneezing, discharge from the eyes and nose, coughing or gagging and a postnasal drip. If your pet has never had such an illness before, it may be wise to have your vet investigate with x-rays or other tests to confirm a sinus infection. If your pet has had sinusitis before, you will probably recognize the signs. Cats with a sinus infection may stop eating due to a decrease in their sense of smell.

The natural way

The immune system plays a large part in preventing sinus infections from occurring in the first place. Unfortunately, repeated antibiotic and anti-inflammatory treatment may further compromise immune functioning, making your pet more susceptible to recurring infection.

Using a more holistic approach, natural remedies can help to safely support sinus health and can also play an important role in maintaining immune system health and functioning. Due to the high safety profile of the ingredients, our natural remedies are also free of side effects.

What are the ingredients?

Sinu-Rite is a 100% homeopathic formula and contains the following ingredients in therapeutic dosage: Glycyrrhiza (3X), Kali bic (30C), Nat mur (6X), Sambucus nig (3X), Pulsatilla (30C).

  • Nat mur (6X) is a biochemic tissue salt that helps to maintain the body's fluid balance and is an essential component of all living cells. This tissue salt has excellent effects in supporting respiratory health and keeping sinuses, noses, and chests clear and healthy, thus supporting the health and integrity of all the mucus membranes of the respiratory tract.
  • Pulsatilla (30C) is a natural remedy useful for keeping sinuses clear and healthy.
  • Kali bic (30C) is a natural remedy that is recommended to soothe the throat and respiratory tract and support sinus health.
  • Glycyrrhiza (3X) is a widely used homeopathic remedy that helps to open up the respiratory system, including the nasal passages. It has even been studied for its supportive effect on the liver (Arase Y, Ikeda K, Murashima N, et al. “The long term efficacy of glycyrrhizin in chronic hepatitis C patients.” Cancer 1997;79(8):1494-1500.)
  • Sambucus nig (3X) is a homeopathic remedy known to help facilitate the loosening of nasal matter, thereby helping to open the nasal passages and have a positive effect on the sinuses and the respiratory system.

This homeopathic remedy is an OTC medicine registered with the Food and Drug Administration (FDA).

PetAlive is the leading brand of natural remedies known for safe, effective and quality products. Our remedies are formulated by natural health experts and produced under the highest pharmaceutical standards in FDA-registered, GMP certified facilities.

Get optimum results with regular use

While conventional medicine works by often treating just the symptoms, natural medicine strives to create holistic balance. Unlike pharmaceutical drugs, the natural ingredients in our remedies support overall health and functioning.

Pets respond to natural medicine in different ways.  Some of our satisfied customers have reported observing immediate results in their pets while many others have reported observing optimal benefits taking effect within 3-6 weeks. To ensure your pet receives optimum results it is important to administer natural remedies as directed and remain consistent. You may also find that giving your pet a smaller maintenance dose is beneficial for ongoing support. Many customers report using a regular maintenance dose as part of a preventative program for the continued health and well-being of their beloved animals.

How long until I see results?

Because Sinu-Rite is 100% homeopathic, it supports the animal body on a cellular level – getting to work upon the first dose. Within a few doses, nasal and sinus decongestion should be noted. Continued improvement will be seen with regular use. While some animals need only a single dose, others may require additional doses, depending on factors such as the age and size of the animal. Response times vary from animal to animal, based on physiological composition and other circumstances. While some animals begin to show an almost immediate improvement that increases over time, others will see results after 3-5 days.

How long does one bottle last?

One bottle of Sinu-Rite contains 180 tablets and will last between 1 and 6 weeks, depending on the size and dosage needs of your pet.

Rated 5 out of 5 by Great Product! I don't remember how I found Native Remedies, but I'm so glad I did. My Tortie cat has always had sinus issues and she is the devil to give a pill too. These pills are so small that I just put it with a treat and drop it in her mouth and she doesn't know the difference. I usually manage to get 3 pills a day into her and find that she does do better when I do. She breaths and sounds so much better and her sneezing is down to a minimum. Thank You so very much for this product! June 16, 2012
Rated 5 out of 5 by Great Product I have a 7 lb Pomeranian named Buffy. She was a rescue dog who was approx. 6 mo. old when I got her from a shelter. After a few weeks I noticed she seemed to get choked, almost like she had post nasal drip that made a cough and snort several times a day. Her Vet said it was allergies. We live in the South and that was not unusual for the time of year. It was not getting better however, and I hated to see her having this discomfort. I began to research her symptoms. I ran across this product on the internet. I am a believer in holistic and natural supplements for myself and thought I would give this a try for Buffy. After only a few days of her taking Sinu Rite twice a day her symptoms were almost non existent. After a few weeks I cut back to one a day. I continue to give it to her once a day as maintenance. This product has done wonders for her. Thank you Native Remedies. June 15, 2012
Rated 5 out of 5 by Something that finally worked for my dog, Birdie! I was about to give up hope that I could ever find anything to help my dog Birdie with her running nose. After surgery and numerous antibotics and anti-inflamatory pills from the vet that offered her little relief I was afraid that I was going to have to put her to sleep because I did not want to see her suffer anymore. Sinu-Rite was my last hope and it worked! I almost could not believe it because I had almost given up hope that I would ever be able to find something that would give her relief. I printed up the page about Sinu-Rite and gave it to my Vet so that he could tell others about it in his practice. Birdie is a 11 year old Westie and is happy and playfull again! I'm about out of my first bottle and I just ordered 3 more bottles today. March 7, 2012
Rated 5 out of 5 by WOW!! I stray cat showed up about 2 yrs ago where I used to live with my older sister. I named him Grandpa. He was a mess, has no teeth, and was definitely an abandoned pet. However, since having him, he has had chronic nasal sneezing, runny nasal and bloody discharge with watery eyes. I seems to have gotten worse in the last six months and I was cleaning his nose and eyes all throughout the day. He looked miserable. I was taking him to the vets for anti-biotics and a steroid shot. But the results were temporary. Next step was to see if perhaps he had a nasal polyp. I read ALL the reviews from satisfied pet owners and decided to give this a try. My order arrived on Tuesday, it has been only two days and what a difference for Grandpa and I!! I don't hear him "snorking"...sneezing is minimal, and I hardly see any eye and nose discharge!! He is a big kitty, but one little pill once at night when I come home and one in the morning before I leave for work seems to work great and the pill is so small and easy to give him. Thank you...thank you...for making such a great product!! January 19, 2012
Rated 5 out of 5 by Great for pet colds and long-term health Our 13-year-old cat had suffered an annual cold and, sometimes, respiratory problems. We began giving him Sinu-Rite (and Respo-K) daily crushed up in his food. He no longer gets the full-blown cold (just some runny sinuses once in awhile). Considering a vet visit runs $150 to treat him for this condition, Sinu-Rite and Respo-K are an excellent value. January 6, 2012
Rated 5 out of 5 by Really worked for my cat My cat seems to have a number of allergies and Sinu-Rite worked fast! It has cleared up his congestion and stopped his coughing. I crush the pill and put it in his food and have had no problems. I'm so glad I found something natural to help him. I highly recommend this product. October 24, 2011
Rated 5 out of 5 by Greatley Helped my Pekingese I just started using this product on my 9 year old pekingese and couldn't be happier. I noticed his breathing getting heavier over the last few months so I decided to try this product. After a few days I started noticing a difference, especially when he Is sleeping. I used to have trouble sleeping due to his nasal congestion! Now I barley notice. He has also stopped sneezing so much. Thank you for this great product! August 30, 2011
Rated 5 out of 5 by Great Product For the last 6 Months my cat sounded like he needed to blow his nose. After giving him Sinu-Rite for only two days he was sounding almost normal. After the first week I only gave him one pill a day and after two more weeks he is now back to normal. To get him to take the pill I just placed it inside a small piece of American cheese and he really loved it. July 25, 2011
Rated 5 out of 5 by The only thing that works for my Persian cat! My persian cat has allergies and used to be so sneezy and wheezy! I give him 1 Sinu-rite and 1 Respo-k tablet in the morning, and one of each again at night. I put the tiny pills inside a soft treat and he gobbles it right up. Using these products has reduced his sneezing and wheezing by at least 80 percent. I was amazed! I really wasn't expecting it to work. It didn't work immediately at first, it took a few days until i noticed great results May 21, 2011
Rated 5 out of 5 by Surprisingly Effective We love this product. It does exactly what it says. It clears nasal passages and improves breathing. I highly recommend this product. April 6, 2011
Rated 4 out of 5 by Sinu-Rite has improved my cat's sinus health My 18-year-old cat has been receiving Sinu-Rite for about 8 months. He showed some improvement fairly soon after starting, and I have seen significant results over time--especially regarding "wet sneezes" and nasal wheezing. August 15, 2012
Rated 3 out of 5 by So far, so good My six yr old maine coon was diagnosed with a herpes viral complex which mainly affects her sinuses, she has horrible stuffiness and sneezing fits with lots of goo. Ive been giving her this three times a day for about one month during flare periods and it seems to have lessened duration and severity. I also recommend vetronquil l lysine powder which she gets two scoops of everyday and if I somehow miss a day her symptoms can start up again. Consistency is so important with supplements!

How has Sinu-Rite helped others?

Sinu-Rite has been used to help relieve symptoms of sinusitis. Here is what some pet owners have to say:

“William is a Birddog extraordinaire. Only his sinus infections kept getting in the way of his work. This led to many trips to the doctor and a near death experience when it was discovered (almost too late) that he was deathly allergic to penicillin. Sinu-Rite has allowed William to once again look forward to the fall and his favorite passion; hunting the wise and cunning Pheasant.”

- Tim A., OR, USA

“I wanted to write and tell you about my experience with your natural remedies. I am a big cat-lover and have a house full of pets. Your PetAlive has become one of my favorite websites and I've ordered a number of different remedies for my extended "family". Although I have been happy with everything I've ordered from you I must specifically comment on your Respo-K and Sinu-Rite products. I have one cat who often gets respiratory tract infections and it's almost a given that her sinuses become involved. We have battled with this problem and I can't tell you what I've spent in vet bills and antibiotics. Last time she got an infection I gave her Respo-K and Sinu-Rite and she recovered much more quickly than usual. I continued to give her the remedies for a little while after she was well again and she hasn't had a repeat infection since. She actually seems much stronger and healthier overall as I'm sure the numerous illnesses were putting a serious strain on her health and energy. I am going to make sure I always have stock of these remedies in my house from now on!”

“Your Sinu-Rite remedy cleared up my dog’s chronic sinusitis better than anything else I have ever tried. Different vets had different ideas about what the problem was - allergies, bacterial infection etc. but whatever it was, Sinu-Rite sorted it out! Thank you so much!”

- Drew

“My 17 yr old cat was diagnosed… We tried traditional [medications] and they did not help… So I bought Sinu-Rite and started giving my 6 pound cat one pill a day for about 1.5 yrs. Then I decided to give her 2 a day as the bottle said as many as 6 pills per day could be administered. I believe that the Sinu-Rite allowed my cat to live another 2 yrs with a milder form of the [problem]. It eased her symptoms and kept her more comfortable till she recently passed away at 19 yrs old.”

- Gina, NJ, USA

“Used one and a half bottles of Sinu-Rite for our cat…. It worked...”

- Ben M., CA, USA

“My Rat Terrier started wheezing, his nose was stuffy and he was snorting and kept me up all night. I was so worried he was going to stop breathing so I could not sleep. I starting giving him [medication for children] and that worked very little and dried him up terribly. So I went online looking for Holistic Medication and came across PetAlive. Placed an order for a few items and one was the Sinu-Rite. Well by the second tablet, my Rat Terrier was energetic and could breath and stopped wheezing. This product is so awesome, I was flabbergasted at how fast and effective it worked. Thank You, Native Remedies.”

- Rose M., FL, USA

“I just wanted to thank you for this wonderful product. We have been battling our cats' sinus conditions for over 3 years. No vet could find a solution and several hundred $ later I felt lost. Even more concerning and upsetting was watching my cat constantly sneezing and often having bloody sinuses from the junk in his lungs. We often wondered if he would ever be the same again. Thanks to Sinu-Rite and Respo-K our cat is back to normal. I want to encourage your readers to buy the combination for their cat or dog. The improvement has been 200% and we are all much happier. Thanks for providing such great products!”

- April, CO, USA

“I have two rescue Persians with extremely short nasal passages. One, in particular, has always had severe eye and nasal discharge, wheezing, stuffed up nose, etc. She has been to the vet numerous times and treated …I started her on Sinu-Rite about a week ago and am amazed at her improvement. For a few days she was completely clear, could breathe, etc. Then she caught a cold and is sneezing, etc. I am going to add Respo-K and the Immunity and Liver [Support] to see if that improves her immune system and respiration. Thank you for your wonderful products!”
