DescriptionValacyclovir is an antiviral drug. It slows the growth and spread of the herpes virus so that the body can fight off the infection. Valacyclovir lessens the symptoms of these infections and shortens the length of time you are sick.
Valacyclovir (generic Valtrex) Reviewgeneric name: ValacyclovirWhy is Valtrex prescribed?Valtrex is used to treat certain herpes infections, including herpes zoster (the painful rash known as shingles), genital herpes, and herpes cold sores on the face and lips. Most important fact about ValtrexValtrex should not be used by anyone with a weak immune system, such as those with HIV infection or those who have undergone a bone marrow or kidney transplant. Valtrex can cause serious side effects, including death, in such people. What side effects may occur?Side effects cannot be anticipated. If any develop or change in intensity, inform your doctor as soon as possible. Only your doctor can determine if it is safe for you to continue using Valtrex.
Recommended dosageSHINGLES The usual dose is 1 gram 3 times a day for 7 days. Patients with kidney problems or HIV infection may need a reduced dosage. COLD SORES The recommended dosage is 2 grams twice a day for 1 day, taken about 12 hours apart. Valtrex should not be taken for more than 1 day. The elderly and people with kidney problems may need a reduced dosage. GENITAL HERPES The usual dose for the first attack is 1 gram twice a day for 10 days. For later attacks, the dose is 500 milligrams twice a day for 3 days. To keep the condition from returning, the dose is 1 gram once a day. If you've had less than 10 infections per year, your doctor may prescribe 500 milligrams once a day. The safety and effectiveness of Valtrex treatment beyond 1 year have not been studied. Special warnings about ValtrexHigh doses of Valtrex have proved dangerous in people whose immune system is compromised because of HIV infection, bone marrow transplant, or kidney transplant. Effects on the central nervous system are more common in older adults, confusion, leading to such symptoms as agitation, and hallucinations. Their kidneys are also more likely to be affected; and those with kidney problems need a smaller dose. In addition, older adults tend to suffer the pain of shingles for a longer time after healing has begun. If your kidneys are not functioning properly, or you are taking drugs that may damage the kidneys such as Neomycin or Streptomycin, Valtrex can make your condition worse or affect your central nervous system (brain and spinal cord). Valtrex relieves the symptoms of genital herpes, but it is not a cure. There's also no evidence that it will prevent transmission of the disease. To avoid spreading the infection, don't have sexual intercourse during a flare-up. Valtrex is not intended for use in children. OverdosageWhen taken by people with kidney disorders, excessive doses of Valtrex have been known to cause psychological problems and kidney failure. If you suspect an overdose, check with your doctor immediately.
