Lifts and opens your nasal passages. Opens your nose up to 38% more than decongestant sprays alone. Can be used by people ages 5 and older. Large is recommended for adults with larger noses. Breathe Right Original Nasal Strip is a drug-free, non-prescription device that works mechanically – from the outside – to gently open nasal passages. This reduces the resistance to air flowing through the nasal passages and improves the ability to breathe through the nose. Within each Breathe Right strip are flexible, "spring-like" bands. On the underside is a special adhesive that, when placed properly on the nose, gently sticks to the area right above the flare of each nostril. As the bands attempt to straighten back to their original shape, they gently lift the sides of the nose and open the nasal passages, providing immediate and continual relief.
