Step 2: Peel back the cover of the blister pack. Take 1 SITAVIG out of the blister pack. When removed from the blister pack, SITAVIG must be used right away. SITAVIG is round on one side and flat on the other side (See Figure B).
Step 3: Place the flat side of SITAVIG on your dry fingertip. Apply the round side of SITAVIG to your upper gum (See Figure C). The flat side will be facing the inside of your lip.
Step 4: Hold SITAVIG in place by applying a slight pressure with your finger on the outside of your upper lip, over the area where SITAVIG is placed, for 30 seconds. This will help SITAVIG stick to your gum (See Figure D).
