Cartrophen Vet is given by injection to treat degenerative joint disease or arthritis in dogs. It has been found that it provides relief from pain, stiffness and lameness as effectively as the non-steroidal anti-inflammatory drugs commonly used in veterinary medicine. Normally a course of 4 injections is given at 5-7 day intervals. The beneficial effects are normally noticed after the second or third injection. The improvement usually continues until after the last injection is given, and then this is usually maintained for a few months after the fourth injection. If some deterioration is noted in future, the course can be repeated, of some vets will give a single injection once per month to help maintain the beneficial effects.
Please Note: Cartrophen Vet Injection does not come with a syringe or needle. To obtain these items separately, click here.
Cartrophen Vet contains Pentosan Polysulphate Sodium which is a semi-synthetic polymer. It has anti-inflammatory properties which particularly affect the cartilage within synovial joints. Cartrophen modifies the metabolism of the cartilage and the production of the lubricating synovial fluid. Cartrophen influences the underlying disease processes occurring in arthritis, reducing pain and helping regenerate damaged joint components.
Cartrophen is not recommended for young, growing dogs or for pregnant bitches. Cartrophen is sometimes prescribed by vets for use in horses. (It is exactly the same product which is used in both species.)
Previously it was recommended that Cartrophen should be stored at fridge temperatures. The manufacturer has now updated the storage information so that cold storage is not required. It is now recommended that Cartrophen is not stored above 25°C and that once the first dose has been used, the remainder is used or discarded within three months. Cartrophen is no longer shipped in a cold pack. Cartrophen will continue to be supplied in old packaging for a while which shows the old storage instructions. However the new requirements are as per the datasheet below. The official datasheet can also be viewed at www.noahcompendium.co.uk.

Below are some recent questions we've received regarding Cartrophen Vet Injection, including answers from our team.
Please could you tell me if there are any known side effects to this medication?
Cartrophen is a well known safe medication with only very mild, transitory side effects if at all. Very rarely it can cause dogs to vomit after the first injection or be a little quieter for 24 hours after.
My vet has prescribed cartrophen course of 4 injections followed by 3mthly injections. He is a well used stud dog of 5 years. Will this affect his fertility in any way. His next bitch is due to be mated in 6 weeks approximately.
Cartrophen is not known to adversely affect the fertility of male dogs so his performance as a stud dog should not be affected.
How do you gage dosage for a 600kg horse? How many bottles do you need for a course?
You would have to talk to your vet about this. Generally a 10ml bottle is given to a 450kg horse once weekly for 4 doses. A 600kg horse would ideally receive one and a third bottles per week for 4 weeks, so 6 bottles would be needed for your horse with some left over at the end of the course. Many vets would give one bottle per week even for a 600kg horse, so 4 bottles would do, though this is a slight under-dose.
Is this Cartrophen suitable for horses? It's unclear if there are differences between the canine and the equine type.
There is only one type of Cartrophen. It is licensed and manufactured for use in dogs only. However it has been used widely in horses by many equine vets and so has become regarded as safe and effective for horses too. This is regarded officially as "off-license use" but since there is nothing like it manufactured for horses, the canine product has to be used.
Does it have to go in the fridge once opened?
Cartrophen Vet Injection doesn't require refrigeration but should be stored below 25°C. After opening, any unused contents must be discarded after 3 months.
Can I order Carrtophen jnjection from Australia without a vet prescription. What would be the cost for postage. Thank you Chris
We believe you cannot legally import Cartrophen without a prescription and we would require one for export to Australia. Now that Cartrophen no longer requires to be stored at fridge temperature, the current Royal Mail standard international postage fee (August 2013) to Australia is £10. It is possible to choose courier delivery during the checkout process and the cost of this is higher. All costs are itemised in the shopping cart before you need to make payment. You can always decide not to proceed with payment if you are not happy with charges, and amendor delete your order as you wish.
