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.


Powder for oral solution or in-feed use. Each gram contains 10 mg bromhexine hydrochloride per gram.


Bisolvon is a mucolytic for use as an aid to the treatment of respiratory disease in cattle, pigs, dogs and cats where mucus is a complicating factor.

Cattle, calves, pigs, piglets, dogs and cats

Further information

May be used in conjunction with antibiotics and/or sulphonamides, bronchodilators etc. Bisolvon has been shown to increase mucocillary clearance in calves suffering from respiratory disease.

When Bisolvon is administered simultaneously with oxytetracycline in cattle and pigs, the levels of the antibiotic in the bronchial mucus are considerably increased (by more than 40%). The clinical significance of this action is uncertain.

Below are some recent questions we've received regarding Bisolvon Oral Powder, including answers from our team.

Ask Your Own Question


20th Mar 2018

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.

  • Veterinary Advisor

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

  • Non-Executive Director

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?

  • Non-Executive Director

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.
