Bisolvon powder is added to food once or twice daily. It is used in dogs, cats, pigs and cattle. Bisolvon acts to help clear mucus from the respiratory tract and is useful where the accumulation of mucus might be detrimental. This occurs in respiratory infections and some other respiratory diseases. It is possible that Bisolvon increases the concentration of some antibiotics within the mucus when given concurrently, though this has not been proven to be of benefit.

55 Fantastic Magic Powder!

Using this on a Cat with chronic upper respiratory problem. It was only when I ran out of it I saw just how effective it is on keeping said Cat from getting a flare up. Without it he becomes Snotty and Wheezes and sneezes and gets a Mucus build up. In just a Day and a half back on it he showed a marked improvement. Very impressed with the results.

Alzbeta Jurekova

  • VioVet Staff

There are no listed side effects for Bisolvon as per the datasheet. If your dog is experiencing possible side effects though then I strongly advise seeing your prescribing vet to rule any underlying issues.

How long can bisolvon be used for?

Jayne N

My cat has been on bisolvon for a week now and while it seems to work somewhat while he's taking it, he still has chronic nasal congestion which worsens overnight. I've been trying to treat my cat since January for an upper respiratory infection. He's been treated with doxycycline for 7 weeks, 2x antibiotic injections which last 2 weeks each, flumax and now bisolvon L-Lysine alone. Nothing has cured his problem. Can I keep giving him bisolvon in conjunction with L-Lysine supplement until his body's own immune system tackles this infection?

  • VioVet Staff

There are is no information in the datasheet of this product for long term use. This means it is likely safe but I advise discussing this with your vet as only they can prescribe it for long term use.

Known Bisolvon side effects in cats


I have been prescribed Bisolvon for my cats respiratory infection and I was just trying to do abit of research on the drug. I can’t seem to find any information on possible side effects in cat’s. Are you able to advise of these?

Many thanks

  • VioVet Staff

There are no listed side effects on the data sheet for Bisolvon, this means there are no known side effects. However that does not make side effects impossible. If you are having any problems whilst using the medication I strongly advise contacting your prescribing vet so they can determine if Bisolvon is the cause or not.

Side effect of Bisolvon


Does Bisolvon cause iris melanosis in cats? My cat started to develop this at the same time as starting on the mucolytic.

  • VioVet Staff

There are no listed side effects for Bisolvon so I cannot confirm or deny this. However from medical experience the Iris Melanosis is extremely likely unrelated to the Bisolvon use. The condition is a pigmentation of the iris itself and there is no evidence currently to say that Bisolvon would affect the body's pigmentation system. It is worth discussing treatment with your vet and following their advice.

Cat passing stools more than usual


Can Bisolvon powder for cats cause him to pass more stools during the day, more than usual? Does it have a laxative effect? My cat has been prescribed a pinch of it twice a day mixed with food. Today he’s passed stool 4 times. Can you please advise if this is a normal reaction? Thanks.

  • VioVet Staff

Increased stool production is not a normal side effect of Bisolvon and it is unlikely related. If the stools are normal in consistency then this can be stress related and I would monitor them, but if they are soft or your cat is abnormal in any other way then I advise contacting your vet.

Hi Bisolvon has been very helpful in treating my Persian cat who suffers regularly from blocked nose and sinuses which makes breathing very hard work for her. When asked our vet advised it was possible to keep her on Bisolvon on an ongoing daily basis, which I have done and occasionally I have increased the dose when a bad attack was threatening. She's been on this medication for about 5 months. However the cat also now gets coughing/wheezing attacks most days as if she is trying to clear liquid from throat or lungs. It's just occurred to me that these coughing fits have only started in recent months - so could it be a side effect from the mucolytic? Affecting the viscosity in her chest/throat adversely? My plan is to stop the Bisolvon for a while (unless she gets a bad nasal attack) to see if wheezing attacks improve. It's as if she is trying to bring up a fur ball - and movement will trigger it (eg picking her up). And if I put her back on Bisolvon I will stick to recommended dose. I would welcome your thoughts?
Clemmie is not helped by her poor Persian face design so if her nose gets blocked she really struggles to breathe. She is 16 and otherwise healthy.

  • VioVet Staff

Bisolvon will make the mucus less sticky and easier to cough up. The coughing attacks your cat is having are likely to be helping clear her airways. I would not stop the Bisolvon if your vet has recommended she stays on it. Coughing in my opinion is preferable to struggling to breathe though you should discuss this with your vet if you do decide to stop treatment.

How long does it take to work


My cat has been put on bisolvon by the vet for cat flu.he has been on it for 24hrs when will I notice it is working

  • VioVet Staff

Nothing will suddenly make your cat completely better. Bisolvon often helps to clear the airways a little, but it is not very powerful and cat flu is not easy to treat. You have to give the treatment a bit more time perhaps. Otherwise, see your vet again.

I would like to know if bisolvon can be used in poultry too?

  • VioVet Staff

Bisolvon can be used in poultry and is effective. 1 sachet per 10kg bodyweight has been used as a dose, once or twice daily. Always talk to your own vet about this first. Standard withdrawal periods should be followed where applicable.
