Product Details

Theophylline can help to ease breathing in pets who suffer from respiratory disorders due to heart failure, pulmonary edema, bronchial asthma, chronic obstructive pulmonary disease(COPD), and other disorders.

What is Theophylline? Theophylline is an oral tablet that is classified as a bronchodilator. It helps to relax airways and make breathing easier in pets who suffer from multiple respiratory disorders.

What are the benefits of Theophylline?
  • Can help relieve breathing in pets suffering from a variety of cardiovascular/respiratory disorders.
  • FDA approved
  • Easy to give tablets

Formulated for:cats and dogs.

How is this medication given?Theophylline is given orally preferably at the same time(s) daily exactly as directed by your veterinarian.

Always consult with your veterinarian if you have questions regarding the proper use of Theophylline.

How does this medication work? Theophylline causes relaxation of the smooth muscles in the airways and lungs. Muscular relaxation increases the airway diameter and helps maximize the flow of air through them making breathing easier. Theophylline may also assist in draining excess fluid from the body through the kidneys.

What results can I expect? Theophylline can help to make breathing easier for your pet but it does not cure underlying illnesses. Theophylline is effective after several hours so it is not effective for acute asthma attacks. Symptoms may return if medication is stopped.

What form(s) does Theophylline come in? This medication is available as a tablet.

Generic Name:Theophylline (Common Drug Name)

Common Brand Name:Theo-Dur

Dose and Administration:Give the prescribed amount of tablet(s) by mouth preferably at the same time(s) every day according to your veterinarians exact directions.

Give a dose as soon as you remember if you forget one but never double dose. Give Theophylline only to the pet it has been prescribed for. Consult with your veterinarian if you are unsure of how to Theophylline correctly.

Uses:Theophylline is used to relieve breathing in pets who have breathing troubles as a result of multiple respiratory/cardiovascular disorders including heart failure, pulmonary edema, bronchial asthma, and COPD.

Possible Side Effects: Loss of appetite, nausea, vomiting, diarrhea, and nervousness have been reported but these symptoms usually disappear after Theophylline has been given for a while. Some pets can experience increased appetite, drinking, or urination, seizures, or abnormal heart rhythms. An allergic reaction is possible in pets who are hypersensitive to Theophylline. Other side effects are possible.

Contact your veterinarian immediately if your pet is acting ill while taking Theophylline.

Drug and Food Interactions: Other medications and supplements your pet is taking should be reported to your veterinarian prior to starting Theophylline. Some drugs may interact with Theophylline including Phenobarbital, phenytoin, cimetidine, erythromycin, and beta-blockers. Other drug interactions may occur.

Precautions:Theophylline should never be given to pets who are allergic to it or similar medications (ex. xanthines, theobromine, caffeine). 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 may have trouble with this medication and it should only be used in these patients when your veterinarian thinks the benefits outweigh the risks.

Storage: Store tablets at room temperature out of reach from children and pets.
