What is the most important information I should know about theophylline (Elixophyllin, Theo-24)?
Do not take theophylline in larger or smaller amounts or for longer than recommended. Theophylline overdose can occur if you accidentally take too much at one time, or if your daily doses are too high. To be sure you are using the correct dose, your blood will need to be tested often.
Do not start or stop smoking without first talking to your doctor. Smoking changes the way your body uses theophylline, and you may need to use a different dose.
Sometimes it is not safe to use certain drugs at the same time. Many drugs can interact with theophylline. Tell your doctor about all other medicines you use. Also tell your doctor if you start or stop using any of your other medications.
Stop using theophylline and call your doctor at once if you have severe or continued vomiting, rapid heartbeats, confusion, tremors, or seizure.
