Daily Life Interactions for Quibron-T/SR 300mg Extended-Release Tablet

Elements of your daily lifestyle may have an effect on the medications you are taking. Drug interactions can result in unwanted side effects, reduce the effectiveness of your medicine or possibly increase the action of a particular medicine.

Major Lifestyle Interaction
Tobacco and Quibron-T/SR 300mg Extended-Release Tablet(Theophylline, Anhydrous)
Tobacco and Theophylline(Theophylline, Anhydrous)
Tobacco smoke contains substances that may speed the removal of Theophylline or Aminophylline from the body; if you start smoking, the Theophylline or Aminophylline may become less effective. Just the opposite occurs when someone stops smoking tobacco; if you stop smoking this may increase the amount of Theophylline or Aminophylline in the blood. Side effects from Theophylline, Aminophylline may get worse. Too much Theophylline or Aminophylline can cause nausea, nervousness, or sleeplessness, and occasionally other effects like rapid heartbeat, tremor, or seizures. Notify your prescriber if any of these effects occur. Your prescriber may need to closely monitor the blood level of Theophylline whenever a change in tobacco smoking occurs, so inform your prescriber if you are a smoker or if you are going to stop smoking.
Moderate Lifestyle Interaction
Caffeine-containing Foods/Beverages and Quibron-T/SR 300mg Extended-Release Tablet(Theophylline, Anhydrous)
Caffeine-containing Foods/Beverages and Theophylline(Theophylline, Anhydrous)
