Cartrophen Injection Course
Safe, plant-based joint support for dogs and cats
Cartrophen is a veterinary medication we’ve trusted for decades at Pittwater Animal Hospital. It’s a plant-derived compound called pentosan polysulfate sodium, used to improve joint function, reduce inflammation, and slow the progression of arthritis.
We find Cartrophen to be extremely safe, cost-effective, and well tolerated in both dogs and cats.
🩺 How is Cartrophen given?
Cartrophen is administered as a subcutaneous injection (under the skin), once a week for 4 consecutive weeks.
-
🐾 The first injection will be given by one of our veterinarians.
-
💉 The remaining three are administered by our experienced veterinary nurses.
-
📅 An appointment is needed each time.
🐕 Who benefits from Cartrophen?
Any dog or cat with joint issues may benefit from a Cartrophen course. It is especially useful for:
-
Pets with a history of joint surgery or previous joint injury
-
Pets showing early signs of arthritis or stiffness
-
Older animals slowing down with age
For pets with more significant joint degeneration, we may recommend:
-
Two Cartrophen courses per year, or
-
Monthly maintenance injections
💡 Annual Cartrophen boosters
We often recommend repeating the 4-week Cartrophen course once a year as a proactive way to support joint health — an ounce of protection is worth a pound of cure!
If your pet is due for their yearly vaccination and check-up, we can time the Cartrophen course to begin then. This means:
-
The course can be given as nurse-only visits (after vet assessment)
-
💸 The cost is reduced, as no repeat consultation is needed for the nurse appointments
💊 Combining Cartrophen with other treatments
Cartrophen can be used alongside:
-
🦴 Joint supplements (e.g. 4Cyte, Antinol)
-
🐾 Dietary changes and exercise management
Many pets show dramatic improvement when Cartrophen is part of a combined arthritis management plan.
🌿 What to expect
Cartrophen is very safe and side effects are rare. Most pets experience:
-
Improved movement
-
Reduced stiffness
-
Increased comfort and vitality
Results may be gradual, taking a few weeks to become noticeable — but for many pets, the difference is life-changing.
