On Monday, January 23, the UFC-Que Choisir once more pinpointed several drugs targeting various winter ailments such as the common cold.

“No proven effectiveness once morest the common cold”
The UFC-What to choose recalls what “The 2018 ban for specialties containing pseudoephedrine prompted companies to promote their cold remedies containing antihistamines, a class usually given in allergies. This is the case with the Fervex and Humex ranges, where there are products with pheniramine or chlorphenamine”.
The association believes that these treatments “have not proven effective once morest the common cold”specifying :
The trials that evaluated them alone in this indication show a small action the first two days on the intensity of the symptoms, but none the following days, and they made no difference with a placebo on the runny nose, the sensation of stuffy nose and sneezing.
Significant side effects
Beyond a questionable effectiveness, pheniramine and chlorphenamine are accompanied, mainly in the elderly, by undesirable effects: dry mouth, constipationblurred vision, rapid heartbeat…
These first-generation antihistamines can cause daytime sleepiness.
Beware of drug stacking
Beyond all this, care should be taken with the composition of these drugs. Because if you are already taking paracetamol, an overdose of paracetamol can have effects on the liver dramatic and irreversible.
It is thus recommended, in case of a cold, to stick to paracetamol as well as sea water to clean the nose. All this, respecting the dosage indicated on the instructions for these drugs. Simply.
