  3. Give cats 2 mg per pound of body weight every 8 to 12 hours.

Frequency of Use:

Store Aminophylline in a tightly closed container, at room temperature, and away from moisture, light, and heat. Do not keep Aminophylline in the bathroom or next to the kitchen sink. Keep away from children and pets.

It is a violation of Federal Law to use this product in a manner inconsistent with its labeling.

Aminophylline works by relaxing the smooth muscles in your pet's airways that contract and impede airflow during an asthma attack or other respiratory event. These airway contractions, called bronchospasms, prevent normal breathing and require treatment to prevent complications and death. Aminophylline works quickly to improve airflow. It also acts as a stimulant on the central nervous system.


Keep this product out of reach of children and animals. Do not use or store in or near open flame or heat.

Aminophylline is intended for use in cats and dogs only. Do not give to other animals.

CAUTION: Use cautiously in animals with heart or liver diseases.

Side effects associated with use may include nervousness, anxiety, and gastrointestinal dysfunction. Less common side effects include insomnia, increased thirst and hunger, frequent urination, vomiting, and diarrhea.

Overdose may cause rapid heart rate, seizures, fever, arrhythmias, and death.

Aminophylline may interact with certain medications, including calcium channel blockers, corticosteroids, ketoconazole, diuretics, and other drugs. Tell your veterinarian if your pet is currently taking any medications or supplements before beginning therapy with Aminophylline.

Do not use Aminophylline in animals with a known allergy to it or to similar medications.
