Good morning, the son about 1.5 mca used theospirex retard. After this time, abdominal and head pains lasting 6 days occurred. Could it have been side effects of the drug? The family doctor suggested withdrawal and observation. After what time is the drug eliminated ( has an elevated alat salt) and these ailments should pass?

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. I enclose information about the possibility of using teleconsultation if a stationary visit would be difficult: https://www.gdziepolek.pl/telekonsultacja I encourage you to report side effects: https://www.gdziepolek.pl/artykuly/jak-i-dlaczego-zglaszac-dzialania-niepozadane
