Otrivin nasal drops 0.1% are used for different types of cold symptoms, designed to be applied in the nostrils where a vasoconstrictive effect occurs, thereby relieving nasal and throat mucous membrane congestion. This effect allows patients suffering from a cold to breathe more easily through the nose. The effect of Otrivin begins within a few minutes and lasts for several hours. Otrivin contains components that help prevent dryness of the nasal mucosa thanks to its extended effect. How to use for adults and children over 6 years old: 2 to 3 drops of Otrivin 0.1% in each nostril, using 4 times a day will be sufficient.
