What You Need to Know About Theophylline For Dogs

Theophylline is an oral drug that belongs to a class of medications known as xanthines. It works by relaxing the smooth muscles around the airways, allowing for easier breathing and improved oxygen flow throughout the body.

Although it was commonly prescribed for dogs who were suffering from respiratory conditions, it has been discontinued due to safety concerns.

If your dog is currently taking Theophylline, it’s important that you talk to your veterinarian about alternatives. Depending on your pet’s condition, they may be able to prescribe a different medication or suggest lifestyle changes that can help alleviate their symptoms.

It’s also important to make sure that any new medications are compatible with any other drugs that your pet might be taking—including supplements or over-the-counter medications—to ensure their safety and well-being.

Additionally, it’s important that you keep an eye out for any side effects associated with the new medication or lifestyle changes you implement for your pet.

If you notice any concerning symptoms such as vomiting or lethargy, contact your veterinarian right away for further advice and support.


It can be disheartening when a beloved pet is no longer able to take a certain medication due to its discontinuation.

However, there are still plenty of options available to treat respiratory conditions in pets including alternative medications and lifestyle changes such as dietary modifications and exercise regimens tailored specifically for them. Talk with your veterinarian about what options are available so that you can find the best solution for your pup!
