Side Effects of Zovirax
Patients with oral or genital herpes should learn about the side effects of Zovirax before filling a prescription.
Zovirax is the brand name for a topical cream or ointment and an oral capsule sold only by prescription for the treatment of herpes simplex virus- 1, herpes simplex virus- 2, herpes zoster (shingles) and chickenpox. The generic name for Zovirax is acyclovir.
Acyclovir, or Zovirax, is an antiviral drug. It works by decreasing the length and severity of herpes outbreaks, helping sores and blisters to heal faster, and reducing the pain and itching associated with herpes, shingles, and chickenpox.
Unfortunately, Zovirax does not “cure” herpes. The herpes virus remains in the body forever. People with herpes can infect their partners and other people around them even between outbreaks.
Before automatically filling a prescription for Zovirax, it is important to learn about the side effects of the drug. Knowing the side effects of Zovirax will help patients with oral and genital herpes make informed decisions about their health care.
