Follow your doctor’s instructions on dosing. The normal dose is one to two sprays applied into the nostril/s of the affected side (headache) as soon as possible. After blowing your nose to clear your nostrils tilt the head back and insert nasal applicator into affected side nostril while blocking the other nostril with your finger. Press down on the pump while breathing deeply through the nostril. If the headache is bilateral (both sides of the head) apply spray into both nostrils. If it is unilateral (one side of the head) it is sprayed into the nostril of the affected side.
