Zovirax

Zovirax Drug Information

• Zovirax Overview

  Acyclovir is used to treat infections caused by certain types of viruses. It treats cold sores around the mouth (caused by herpes simplex), shingles (caused by herpes zoster), and chickenpox. Zovirax is also used to treat outbreaks of genital herpes. In people with frequent outbreaks, acyclovir is used to help reduce the number of future episodes. Acyclovir is an antiviral drug. However, it is not a cure for these infections. The viruses that cause these infections continue to live in the body even between outbreaks. Acyclovir decreases the severity and length of these outbreaks. It helps the sores heal faster, keeps new sores from forming, and decreases pain/itching. Zovirax may also help reduce how long pain remains after the sores heal. In addition, in people with a weakened immune system, acyclovir can decrease the risk of the virus spreading to other parts of the body and causing serious infections.

• How to Use Zovirax

  Take Zovirax by mouth with or without food, usually 2 to 5 times a day as directed by your doctor. Drink plenty of fluids while taking Zovirax unless your doctor directs you otherwise. If you are using the liquid form of Zovirax, shake the bottle well before each dose. Carefully measure the dose using a special measuring device/spoon. Do not use a household spoon because you may not get the correct dose. Zovirax works best when started at the first sign of an outbreak, as directed by your doctor. It may not work as well if you delay treatment. Dosage of Zovirax is based on your medical condition and response to treatment. In children, Dosage of Zovirax is also based on weight. Zovirax works best when the amount of drug in your body is kept at a constant level. Therefore, take Zovirax at evenly spaced intervals. To help you remember, take it at the same times each day.
