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.

  • 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.

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.
