1Acyclovir 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. This medication 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 decreases the severity and length of these outbreaks. It helps the sores heal faster, keeps new sores from forming, and decreases pain/itching. This medication 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. Acyclovir belongs to the class of antiviral medicines, which are used to treat viral infections. Primarily, these medications are only effective against a certain kind of viral illness. Acyclovir may also be used to prevent the recurrence of genital herpes infections. GET YOUR COPY RIGHT NOW BY SCROLLING UP AND CLICKING BUY NOW TO GET YOUR COPY NOW IN ONE CLICK
