Theophylline Extended Release Tablets

Theophylline ER (extended release) is a bronchodilator used in the treatment of heart failure, pulmonary edema, bronchial asthma and chronic obstructive pulmonary disease (COPD). Theophylline acts by relaxing muscles in the lungs and chest, opening air passages.

Theophylline is available as tablet, long-acting tablet or capsule and liquid.

How this medicine should be used
Theophylline is not FDA approved for use in veterinary medicine; however, it is a commonly accepted practice to use this medication in dogs and cats. 

  • Dogs:  10 mg/lb every 12 hours. 
  • Cats:  2 mg/lb every 8-12 hours. 

Give theophylline on an empty stomach, 1 hour before or 2 hours after a meal. If using the long acting form, do not chew, crush or allow to dissolve on food. Allow plenty of fresh water to drink.

Side effects
Side effects when using theophylline include nausea, vomiting, diarrhea, central nervous system excitement, fever, rash and palpitations. Side effects usually subside with dosage adjustments and/or continued therapy.

Special precautions
Theophylline should not be used in patients allergic to this class of medication. Do not use in pregnant or lactating animals. Theophylline should be used with caution in patients with severe heart disease, liver or kidney disease, hyperthyroidism, hypertension or stomach ulcers. Certain medications such as phenobarbital and phenytoin may decrease the effect of theophylline. Certain medications such as cimetidine, erythromycin, levothyroxine and quinolone antibiotics such as Baytril may cause an increase in the effect of theophylline. Always tell your veterinarian and pharmacist what other medications your pet is taking.
