What is Valtrex and why is it prescribed? Valtrex is used to treat herpes zoster, the painful rash known as shingles. Valtrex is also prescribed to relieve the sores caused by genital herpes. How should you take Valtrex? Follow your doctors directions for taking Valtrex. If you are taking Valtrex for shingles, you should start using it as soon as possible after your doctor has made a diagnosis. It is best to see a doctor and start the drug within 48 hours of first noticing the rash. If you wait more than 72 hours after you first get a herpes zoster rash, the medication may not be effective. If you are using Valtrex for genital herpes, begin taking it at the first sign of an attack. The medication may not be effective if you wait longer than 72 hours after the first attack or 24 hours after a later attack. You may take Valtrex with or without food. If you miss a dose take it as soon as you remember. If it is almost time for your next dose, skip the one you missed and go back to your regular schedule. Do not take two doses at the same time. Store Valtrex at room temperature. Are there any Valtrex side effects? Valtrex side effects cannot be anticipated. If any develop or change in intensity, inform your doctor as soon as possible. Valtrex side effects may include abdominal pain, aggressive behavior, agitation, allergic reactions, coma, confusion, decreased consciousness, depression, diarrhea, dizziness, facial swelling, hallucinations, headache, hepatitis, high blood pressure, joint pain, mania, menstrual problems, nausea, rapid heartbeat, rash, visual abnormalities, and vomiting. What are the possible food and drug interactions when taking Valtrex? If Valtrex is taken with certain other drugs, the effects of either could be increased, decreased, or altered. Be sure to inform your doctor of all the prescription and over the counter medications you are taking. Check with your doctor before combining Valtrex with cimetidine (Tagamet) and/or probenecid (Benemid). Are there any special warnings about Valtrex? High doses of Valtrex have proved dangerous in people whose immune system is compromised because of HIV infection, bone marrow transplant, or kidney transplant. 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. Valtrex is not intended for use in children. |
