Zovirax is a well-known brand name for the antiviral drug acyclovir, and its generic version is widely available and often less expensive in the United States. Understanding **what is the equivalent of Zovirax in the USA?** involves recognizing that the core medication, acyclovir, is the primary equivalent, though other alternatives exist for treating herpes infections.

According to the NIH, valacyclovir is an antiviral medication approved to treat certain herpes virus infections, including shingles and cold sores. This common classification clarifies a frequent misunderstanding: **Is valacyclovir a steroid?** The short answer is no, and understanding the pharmacological differences is key to proper treatment and safety.

While generally considered safe and well-tolerated for prolonged periods, especially in healthy individuals, long-term valacyclovir use can carry potential risks, particularly concerning kidney function. Continuous monitoring by a healthcare provider is advised for those on suppressive therapy to manage and mitigate potential issues.
