USAGE: Theophylline extended-release tablets are indicated for the treatment of the symptoms and reversible airflow obstruction associated with chronic asthma and other chronic lung diseases, e.g., emphysema and chronic bronchitis.

CONTRAINDICATIONS: Theophylline extended-release tablets are contraindicated in patients with a history of hypersensitivity to theophylline or other components in the product.

WARNINGS: Concurrent Illness: Theophylline should be used with extreme caution in patients with the following clinical conditions due to the increased risk of exacerbation of the concurrent condition: Active peptic ulcer disease Seizure disorders Cardiac arrhythmias (not including bradyarrhythmias) Conditions That Reduce Theophylline Clearance: There are several readily identifiable causes of reduced theophylline clearance. If the total daily dose is not appropriately reduced in the presence of these risk factors, severe and potentially fatal theophylline toxicity can occur. Careful consideration must be given to the benefits and risks of theophylline use and the need for more intensive monitoring of serum theophylline concentrations in patients with the following risk factors: Age: Neonates (term and premature), Children <1 year, Elderly (>60 years) Concurrent Diseases: Acute pulmonary edema, congestive heart failure, cor-pulmonale, fever (≥102° for 24 hours or more; or lesser temperature elevations for longer periods), reduced renal function in infants <3 months of age, sepsis with multi-organ failure and shock. Cessation of Smoking Drug Interactions: Adding a drug that inhibits theophylline metabolism (e.g., cimetidine, erythromycin, tacrine) or stopping a concurrently administered drug that enhances theophylline metabolism (e.g., carbamazepine, rifampin). (See PRECAUTIONS, Drug Interactions, Table II ). When Signs or Symptoms of Theophylline Toxicity Are Present: …

Pregnancy: Teratogenic Effects: In studies in which pregnant mice, rats and rabbits were dosed during the period of organogenesis, theophylline produced teratogenic effects. In studies with mice, a single intraperitoneal dose at and above 100 mg/kg (approximately equal to the maximum recommended oral dose for adults on a mg/m 2 basis) during organogenesis produced cleft palate and digital abnormalities. Micromelia, micrognathia, clubfoot, subcutaneous hematoma, open eyelids, and embryolethality were observed at doses that are approximately 2 times the maximum recommended oral dose for adults on a mg/m 2 basis. In a study with rats dosed from conception through organogenesis, an oral dose of …
