FDA Approves Sitavig
The U.S. Food and Drug Administration (FDA) has approved Sitavig (acyclovir) buccal tablets for the treatment of recurring Herpes labialis
Based on proprietary Lauriad® technology, Sitavig comes in the form of a mucoadhesive tablet which the patient places on the gum and which delivers a high concentration of acyclovir directly to the lip, the site of the cold sore infection. In a phase III international study conducted on 775 patients, Sitavig demonstrated a high level of efficacy in terms of healing time with one single tablet containing 50 mg of acyclovir and an excellent tolerance profile.
In addition to its efficacy, Sitavig offers a unique unobtrusive and simple formulation with a single application for the episode's entire duration, representing major advantages for patients suffering from recurrent herpes sores.

- If Sitavig does not stick to your upper gum or falls off of your upper gum within the first six hours after you apply it, the same tablet should be placed back onto your upper gum right away. If this Sitavig tablet does not stay in place, apply another Sitavig tablet to your upper gum.

How to apply Sitavig:
Before you apply Sitavig, find the area on your upper gum, just above either the left or the right incisor. The incisor tooth is the tooth just to the right or left of your two front teeth. This is where you should apply the buccal tablet.
Peel back the cover of the blister pack. Take one buccal tablet 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.
Place the flat side of the buccal tablet on your dry fingertip. Apply the round side to your upper gum. The flat side will be facing the inside of your lip.
Hold buccal tablet 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 it stick to your gum.
Leave the buccal tablet in place until it dissolves.
