Theophylline is a widely used, effective bronchodilator that can be prescribed by your veterinarian. This medication treats a variety of pulmonary disorders and may also be used to treat heart disease in animals. This medication works to open and relax airways in a variety of ways. Constricted airways and mucus build up are two of the main culprits behind difficult breathing.

Theophylline aids in relaxing the muscles surrounding the airway so that breathing becomes less difficult. It also increases the movement of cilia in the airway, which helps clear out mucus. This medication is also helpful in strengthening the diaphragm to aid your pet in combating such constrictions in the future and contains caffeine, which acts to stimulate your pet’s central nervous system.

The medication has certain side effects such as irritation in the stomach, nervous system excitement etc. Other side effects that are likely to occur are vomiting, diarrhea, increased palpitation, a rise in body temperature, increased heart rate, skin rashes etc. However, alter the dosage to control much of these symptoms.

Theophylline is the Generic Alternative to Theolair.
