Sitavig® (acyclovir) 50 mg buccal tablet is indicated for the treatment of recurrent herpes labialis (cold sores) in immunocompetent adults.
- 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.
