Genital herpes is an infection in the form of vesicular eruption caused by a virus; simplex-usually involving the mouth, lips, face (cold sores); zoster-infection of certain sensory nerves causing pain and/or blisters along the course of the affected nerve (shingles/zona); genitalis-lesions on the genitalia.
Around 50 million people in the world suffer from genital herpes and about 1 million people are infected each year. The best part is that many people even do not know that they suffer from the disease because they may not experience the symptoms.
If you have ever felt a burning, tingling or itchy feeling around your genital area, buttocks or thighs, or have noticed red open sores or bumps around the area, you may be one of the many people in the world who has herpes.
There are several medications for the treatment of genital herpes and acyclovir is one of the antiviral drugs developed for the treatment. These include acyclovir (zovarix), Val acyclovir (valtrex) and famciclovir (famir).
Acyclovir (brand name Zovirax) is the oldest of the antiviral medications. It has been available since 1982 in a topical form (ointment form) and sold since 1985 in pill form. Now acyclovir is available in a generic form.
It helps by reducing the replication of the viruses that needs to reproduce itself. Thereby it helps to keep the virus inactive. It is effectively used for the treatment of initial episodes and the management of recurring occurrences of genital herpes. Again, it helps in treating acute herpes zoster and chickenpox.
Studies show that these medications are quite safe and effective and rarely produce any side effects. However, certain side effects could be visible such as some allergic reactions, swelling in body parts, stomach pain or less production of urine in the body.

Acyclovir: Medication For Genital Herpes - San Francisco
Genital herpes is a sexually transmitted disease. Genital herpes, a contagious viral infection caused by the herpes simplex virus (HSV ), affects an estimated 30 million Americans. Each year, as many as 500,000 new cases may occur. Talk to your doctor about how to stop the spread of infection.
Antiviral medication is not always needed to treat a recurrence. This is because symptoms are often much milder than the first episode, and usually last only a few days. Acyclovir is used to treat genital herpes infection. They work by stopping the virus.
Acyclovir is used both systemically and topically, but usually will only help with the symptoms of herpes and will not lead to a cure of the herpes virus itself. Acyclovir is excreted in breast milk. If you are or will be breast-feeing while you are using this prescription herpes medicine, check with your doctor or pharmacist to discuss the risks to your baby.
Treatment choices and regimens for genital herpes vary greatly between individuals and physicians. Treatment of burn, ulcers, acute and chronic wounds typically is directed to keeping the wound as clean as possible and making the patient as comfortable as possible. It has been recognized in this respect that keeping the wound moist is advantageous to patient comfort.
Patients should address specific medical concerns with their physicians. Patients on antidepressants and their families or caregivers should watch for new or worsening depression symptoms, unusual changes in behavior, thoughts of suicide, anxiety, agitation, panic attacks, difficulty sleeping, irritability, hostility, aggressiveness, impulsivity, restlessness, or extreme hyperactivity. Call your healthcare provider right away if you have thoughts of suicide or if any of these symptoms are severe or occur suddenly. Studies reveal thst patients with acyclovir alone healed in an average time of 7.7 days, while patients on the combination healed in an average of 6 days. Only one patient in the acyclovir and vidarabine group had a healing time longer than 7 days, whereas six patients in the acyclovir and placebo group had healing times longer than 7 days.
