Lastin is an allergy nasal spray for people over 6 years old. It helps relieve symptoms of seasonal or year-round allergies by blocking substances like histamine.
1 spray into each nostril, twice a day.
First, prime the pump by spraying a few times into the air until a fine mist appears. Then, blow your nose, hold your head upright, and spray once into each nostril. Do not tilt your head back, as the liquid may run into your throat.
Do not use more than 1 spray per nostril, twice a day.
