How long is Theospirex eliminated from the body?

Yes, Theospirex retard can cause stomach and headaches. These are side effects that have been reported very frequently while taking the drug. They may be exacerbated in people hypersensitive to theophylline. For the period of elimination of the drug from the body, we usually take 5 - times the half-life of a given substance. The elimination time of theophylline (the active substance Theospirex) in children is about 15 - 25 hours. However, it should be noted that this time may be extended, even to over 120 hours, due to individual differences in metabolism and elimination of substances that are influenced by factors such as age, disease entity, taking other preparations and organ dysfunction. If the side effects persist, contact your doctor again.
