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.
