Are there any side effects of theophylline?
If taken in very high does, theophylline could cause nervousness, insomnia, cardiac arrhythmias or seizures. We carefully monitor the amount of drug given to the patient during the procedure to insure that the drug is delivered in safe amounts at therapeutic levels. Some people experience an upset stomach and nausea with theophylline that is usually lessened if it is taken with food. Thus, although there is some potential risk, the risk is quite small compared to the potential benefits that may be realized by the patient.
