    Valtrex dosing for shingles


    Valacyclovir belongs to the class of medications known as antivirals. It is used to treat a viral infection affecting the skin known as shingles (herpes zoster). It is also used to treat cold sores, and to treat and prevent recurrences of genital herpes. It works by interfering with the way the virus reproduces. Valacyclovir works by stopping the virus from multiplying and spreading to nearby healthy cells. It does not cure shingles, cold sores, or genital herpes, but it does help the sores to heal more quickly, and it relieves pain and discomfort. When used to prevent recurrences of herpes, it also reduces the risk of transmission (spreading) of the infection to others. The dose in immunocompromised patients is 1000 mg three times daily for at least seven days (3000 mg total daily dose) and for 2 days following crusting of lesions. This dose should be reduced according to creatinine clearance (see Renal impairment below). For recurrent episodes, treatment should be for three to five days. For initial episodes, which can be more severe, treatment may have to be extended to ten days. For recurrent episodes of herpes simplex, this should ideally be during the prodromal period or immediately upon appearance of the first signs or symptoms. Valtrex can prevent lesion development when taken at the first signs and symptoms of an HSV recurrence. For herpes labialis (cold sores), valaciclovir 2000 mg twice daily for one day is effective treatment in adults and adolescents. The second dose should be taken about 12 h (no sooner than 6 h) after the first dose.

    Herpes zoster (commonly referred to as “shingles”) and postherpetic neuralgia result from reactivation of the varicella-zoster virus acquired during the primary varicella infection, or chickenpox. Whereas varicella is generally a disease of childhood, herpes zoster and post-herpetic neuralgia become more common with increasing age. Factors that decrease immune function, such as human immunodeficiency virus infection, chemotherapy, malignancies and chronic corticosteroid use, may also increase the risk of developing herpes zoster. Reactivation of latent varicella-zoster virus from dorsal root ganglia is responsible for the classic dermatomal rash and pain that occur with herpes zoster. Burning pain typically precedes the rash by several days and can persist for several months after the rash resolves. With postherpetic neuralgia, a complication of herpes zoster, pain may persist well after resolution of the rash and can be highly debilitating. Herpes zoster is usually treated with orally administered acyclovir. It comes in the form of a tablet you take by mouth. Valacyclovir is available as a brand-name drug called Valtrex.

    Prednisone is a synthetic steroid with potent anti-inflammatory effects that is used to treat inflammatory types of arthritis and other conditions. Like other corticosteroids, prednisone works by lowering the activity of the immune system. The drug must be taken according to directions, since misuse, long-term use, or high doses can lead to undesirable side effects. Similarly, discontinuation of the drug in the proper way can help prevent symptoms of prednisone withdrawal. Cortisol is a steroid hormone that regulates a wide range of processes throughout the body, including metabolism and the immune response. It also plays a very important role in helping the body respond to stress. If you take prednisone for more than a few weeks, your adrenal glands will decrease the natural production of cortisol.
