Can I give Fluticomb, Berodual and Pulmicort to a 7-year-old child in one day?

It all depends on what guidelines for the use of Fluticomb, Berodual and Pulmicort you received from your doctor(s). These medicines can be taken together only if they have been prescribed by a single doctor, or if the doctors prescribing these preparations have been informed about what other medicines the patient is already taking, what additional diseases he suffers from and only in such a combination (order) as is apparent from those recommendations. Otherwise, such therapy may not be safe, entailing, among other things, an increased risk of systemic side effects, e.g. adrenal dysfunction. If medicines have been prescribed by different doctors, it is necessary to consult them to determine whether these medicines can be used simultaneously. If so, your doctor may make other recommendations on how to use them. In the event that the drugs have been prescribed by one doctor, please follow the dosage regimen.
