How Does Sitavig Work?

Sitavig delivers concentrated medication that stays localized at the site of viral replication in the mouth. Patients treated with a single dose of Sitavig went an average of 304 days before their next cold sore outbreak compared with an average of 199 days for patients treated with a placebo.¹*

Patients also experienced significant relief from cold sore symptoms in just 3.5 days and completely healed in 5.5 days, when Sitavig was applied within 1 hour of feeling the sensation and before the blister appeared.¹*

 

Be prepared

Even if you have no signs of a cold sore, it’s smart to see your healthcare provider and ask for Sitavig. Go ahead and get your Sitavig prescription filled and keep your Sitavig tablet with you at all times.

Indication & Important Safety Information
INDICATION
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.
