SudoGest is a medicine used in the treatment and relief of nasal congestion. Nasal congestion may occur for any number of reasons - such as from a cold or allergy.
The active ingredient of SudoGest - pseudoephedrine - is a sympathomimetic drug. Pseudoephedrine causes vasoconstriction, that is to say, constricted blood vessels. This is important because expanded blood vessels leak more fluid which causes nasal congestion.
SudoGest is, however, associated with its own range of potential side effects. Among these include a loss of appetite, sleep difficulties, skin rash or itch, restlessness, and anxiety. Some patients may also experience high blood pressure and severe dizziness while taking SudoGest.
