Is it possible to take cold medication together?

Yes, they can be used together. These drugs do not overlap in terms of the content of active substances, and also do not interact with each other. Irigasin is best used before applying Xylometazoline so as not to rinse out the drug. If Rutinoscorbin is used separately with vitamin C, it should be taken into account that in 1 tablet of Rutinoscorbin there is 100 mg of vit. C and remember not to use too high doses (depending on body weight and accompanying diseases, it is recommended not to exceed the daily dose of 1g for gastrointestinal ailments): https://www.gdziepolek.pl/produkty/68342/rutinoscorbin-tabletki-powlekane In the preparation Rutinoscorbin Vitamin C Forte there is 500 mg of vitamin C in one capsule: https://www.gdziepolek.pl/produkty/68343/rutinoscorbin-witamina-c-forte-kapsulki-o-przedluzonym-uwalnianiu
