Veterinarians prescribe Theophylline for pets who are having breathing problems caused by multiple illnesses including heart failure, pulmonary edema, bronchial asthma, and chronic obstructive pulmonary disease.

Theophylline is: a bronchodilator that is given orally in order to relax airways and make breathing easier.

What are the benefits?

    1.Can administer orally at home;2.FDA approved;3.Effective in making pets breathe easier when they suffer from certain respiratory/cardiovascular diseases.

    What outcomes can be expected?

    Theophylline is not a cure but it can help to manage your pet’s symptoms and can help to improve his/her quality of life. It can take several hours for Theophylline to work so it is not effective for acute asthma attacks. Symptoms can recur if this medication is stopped.

    How is it given?

    1.This medication is given by mouth. Always follow your veterinarian’s specific instructions when using Theophylline.

    2. Try to give Theophylline at the same time(s) every day in order to keep blood levels steady.

    3. If you are unsure of how to use Theophylline correctly, contact your veterinarian.

    How does it work? Theophylline works by relaxing smooth muscles in the airways in the lungs. This dilates the muscles around the airways which increases the diameter and helps increase the flow of air through them. Theophylline can also rid the body of excess fluid via the kidneys.

    Theophylline is available as: a tablet.

    Generic Name:Theophylline (Common Drug Name)

    Common Brand Name:Theo-Dur

    Dose and Administration:This medication should be given orally according to your veterinarian’s prescribed instructions preferably at the same time(s) every day.

    If you miss a dose, give it as soon as you remember but never give two doses at once. Never give this medication to any other pets in your household other than the one it has been prescribed for. Be sure to call your veterinarian if you have questions about how to administer Theophylline to your pet.

    Uses:Theophylline is used to relax your pet’s airways in order to ease breathing if he/she suffers from respiratory/cardiovascular disorders including heart failure, pulmonary edema, bronchial asthma, and chronic obstructive pulmonary disease.

    Storage:Tablets should be stored at room temperature away from children and pets.

    Possible Side Effects: More common side effects include loss of appetite, nausea, vomiting, diarrhea, and nervousness. These symptoms are more common at the beginning of treatment and they usually disappear after a short time. Increased appetite, drinking, or urination and seizures or abnormal heart rhythms are also possible. Some pets can also experience a true allergic reaction if they are hypersensitive to Theophylline. Other side effects may occur.

    Always call your veterinarian without delay if your pet seems ill in any way while taking Theophylline.

    Precautions:Do not give Theophylline to pets who are allergic to it or similar medications (ex. xanthines, theobromine, caffeine). Caution should be used in very young or obese animals, debilitated or aged animals, animals with severe heart disease, irregular heartbeats, stomach ulcers, hyperthyroidism, liver or kidney disease, hypoxia, high blood pressure, or a seizure history.

    Drug and Food Interactions: Always tell your veterinarian about all other medications and supplements your pet is taking prior to starting Theophylline.
