About ACYCLOVIR SODIUM

Acyclovir Sodium is a medication aligned to the HCPCS J Code: J0133 for billing, pricing, and reimbursement purposes in the United States. It is an Antiviral drug administered via the intravenous route and manufactured by multiple companies.

According to CMS Drug Use Information: This medication is used in certain people to treat outbreaks of herpes simplex infection of the skin (such as on the genitals), mucous membrane areas (such as the mouth, nose), or brain. It is also used in certain people to treat shingles infection. The viruses that cause these infections live in the body quietly until an outbreak occurs. Acyclovir does not cure these infections, but can speed healing of the sores, decrease pain/itching/formation of new sores, and lower the risk of other problems from the virus (such as infection spreading to other parts of the body/organs, pain even after the sores heal).
