Herpex Cream 5%: Quick Look
Herpex Cream 5% is a topical antiviral with acyclovir designed for herpes simplex infections on the skin think cold sores around the lips and external genital herpes lesions. It doesn’t cure herpes, but it helps shorten healing time and ease burning, itching, and tenderness, especially when you start at the first tingle.
What It Does and Why It Helps
Acyclovir targets the herpes simplex virus right where it’s active. It blocks viral DNA copying so the outbreak slows down. That means less burning and itching and, usually, a quicker path from tingle to healed skin. Start early for the best shot at fast relief—waiting until sores are crusted may still help, just not as much.
