Zovirax is an antiviral drug especially useful for herpes virus treatment. It cannot exactly cure herpes but it helps the organism fight the infection and lessens its symptoms. Zovirax also can be used to treat infections and illnesses caused by herpes viruses, such as genital herpes, shingles, chicken pox, and cold sores.
Zovirax as such is not supposed to harm unborn babies, but mind that herpes virus can easily be passed from infected mother to the child during childbirth, especially in case of genital herpes. That is why if you are being treated for herpes with Zovirax or similar medical preparations, inform your doctor if you are planning a pregnancy or have already conceived. It is extremely important to prevent genital herpes lesions while you are still pregnant so that you do not have them on the time your baby is born. If you have herpes while breast-feeding, do not take Zovirax unless your physician confirms it safe since this drug passes into breast milk and harms a nursing infant through this.
If you have any signs of Zovirax allergy – hives, finding it hide to breath, face, lips, tongue or throat swelling – contact your doctor. Do the same if you have developed a serious side effect, for example, severe pain in your lower back, decrease in the daily amount of urinating, easy bruising or bleading, or unusual weakness.
