The Science Behind Sitavig
The convenient, discrete choice.
Benefits of Sitavig:
- No pill to swallow
- Invisible to others
- Ideal for cosmetic- and appearance-conscious patients with recurrent herpes labialis
- Treatment does not interfere with most daily life activities
- One-time dose
- Second tablet provided in every prescription as backup or for a future outbreak
- Patients generally know their triggers, and should keep Sitavig available to them especially during these times

Where HSV-1 replication takes place
- HSV-1 begins to replicate in the basal layer of the oral mucosa.
- Patient may experience an itching, burning or tingling sensation.
- A lesion may form in 2-3 days.

Lauriad™ delivery system¹
- Muco-Adhesive Buccal Tablet applied to the upper gum over the canine fossa
- Targeted delivery of antiviral drug directly to the site of viral replication

Stays active during viral replication¹
- Specifically designed to slowly dissolve over 12-14 hours
- Covers the window of maximum viral replication
- Provides continuous, targeted delivery of acyclovir
Sitavig reduces salivary viral load2
A single dose of Sitavig reduced the viral load in the saliva 5-fold at the site of viral replication (P=.583), possibly reducing the amount of virus available to return into latency.

More days between outbreaks3*
Patients treated with Sitavig had a average of 105 more days before experiencing a recurrent episode of herpes labialis compared to patients treated with placebo. Plus, 36% of patients remained free from lesion recurrence at 10 months post-treatment compared to 26% of placebo patients (P=.027).

Sitavig patients experienced 35% aborted episodes3
34.9% of patients failed to develop a vesicular lesion when applying Sitavig soon after feeling an oncoming cold sore sensation.
86% of patients were satisfied with Sitavig treatment²
Disclaimer
*Data on the incidence and delay of the next recurrence need further confirmation as they were obtained on a subset of patients.

Indication & Important Safety Information
Sitavig® (acyclovir) 50 mg buccal tablet is indicated for
the treatment of recurrent herpes labialis (cold sores) in immunocompetent
adults.
IMPORTANT SAFETY INFORMATION
- Sitavig® (acyclovir) 50 mg buccal tablet should not be used in patients with known hypersensitivity to acyclovir, milk protein concentrate, or any other component of the product.
- Sitavig has not been studied in immunocompromised patients. No interaction studies have been performed. Sitavig’s safety and efficacy have not been established in pediatric patients.
- There are no available data on Sitavig use in pregnant women. However, published observational studies over decades of use of acyclovir have not identified a drug-associated risk of major birth defects, miscarriage, or adverse maternal or fetal outcomes. It is not known if Sitavig is excreted in breast milk; however, systemic exposure following buccal administration of acyclovir is minimal. Before administration, discuss if the patient is lactating or planning to breastfeed.
- The possibility of viral resistance to acyclovir should be considered in patients who fail to respond or experience recurrent viral shedding during therapy.
- In a controlled clinical trial, the most common side effects (greater than or equal to 1%) for Sitavig were: headache (3%), dizziness (1%), lethargy (1%), gingival (gum) pain (1%), aphthous stomatitis (canker
sores) (1%), application site pain (1%), application site irritation (1%), erythema (redness) (1%), and rash (1%). In the same trial, these side effects ranged from 0% to 3% for placebo.
