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).

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 Works great! I have a 2 yr. old rescue Pug with Megaesophagus and chronic sinus problems. We have the first ailment pretty well under control, but the sinus issue, which included snoring, drippy nose, coughing and regurgitating all of the sinus stuff was getting pretty bad. The Vet put her on antibiotics all of the time, and as soon as she was off a few days , it would start again. This product worked so well, that within 2 days her sinuses seemed to clear up, she slept better and best of all, no spitting up all of the phlegm like she had before. I am thrilled with the results and have just ordered my second bottle along with the Respo-K. Thank you so much for this great works! August 11, 2012
Rated 5 out of 5 by Helped Relieve Chronic Sinusitis My 11 year old cat has had chronic respiratory infections and sinusitis since he was a kitten. After many rounds of antibiotics, they were no longer effective. I tried Sinu-rite as a last resort and to my amazement, it really works! My cat had a constantly runny nose and sneezed large amounts of mucus, and those symptoms have almost completely disappeared. He still has occasional episodes, but they are much less severe than before. Sinu-Rite works! July 19, 2012
Rated 5 out of 5 by Works without any side effects This works to alleviate nasal congestion and helps with the sneezing episodes my dog frequently has due to allergies. July 19, 2012
Rated 5 out of 5 by Unbelievable results! My miniature dachshund has suffered from coughing for years and over the last 4 months sinus problems. The spring and early summer was frightful with her conjestion - every day she was struggling to breath - the evenings being the worst. We tried all types of over the counter meds for allergies with no luck. We used saline drops (not a fun process). Prednisone was the only thing that worked and without it the symtoms came back. Unfortunately there are long term health concerns so keeping her on a steroid was not an option. I read the reviews and thought I'd give Sinu-Rite a try and the vets agreed. We received Sinu-Rite on June 21st and in two weeks have had only one morning with a slightly stuffy nose (I upped her dosage that day and it went away). Her congestion problems for the time being are gone and I can only hope it continues. I give her 3 tablets a day (she's 11 lbs) but will go up to 5 pills if I sense the slightest congestion. Thank you Native Remedies, I dont have to watch her struggle breathing anymore!!!! July 3, 2012

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.”

“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.”

“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!”
