The objective of this study was to assess the safety and efficacy of an oral dosage of valacyclovir, 1 g TID versus 2 g TID, for the treatment of herpes zoster in immunocompromised patients ⩾18 years of age. The oral dosage schedule of 2 g of valacyclovir TID reaches acyclovir plasma levels similar to those achieved with intravenous acyclovir therapy given to immunocompromised patients (10 mg/kg every 8 h for 7 days). In this double-blind study, 87 immunocompromised patients with clinical evidence of localized herpes zoster were randomized to receive oral valacyclovir therapy for 7 days, either 1 g TID or 2 g TID, within 72 h after onset of zoster rash. Patients were seen and assessed for cutaneous healing, zoster-associated pain (ZAP), and/or zoster-associated abnormal sensations (ZAAS), up to 24 weeks. Participants in both arms of the study demonstrated similar median times to full crusting of the rash (8 days), and both dosages were safe and effective therapies for reduction of ZAP and ZAAS in the immunocompromised patient population Trials registration Clinical identifier: NCT00006131 Herpes zoster, or shingles, is a common disease caused by a reactivation of the varicella-zoster virus (VZV).

    Your order will be packed safe and secure and dispatched within 24 hours. This is exactly how your parcel will look like (pictures of a real shipping item). It has a size and a look of a regular private letter (9.4x4.3x0.3 inches or 24x11x0.7cm) and it does not disclose its contents I prefer not to take generics of Nolvadex if I can buy the original Nolvadex online from the certified company. The seller cares about its name and image and makes a quick delivery. As for me, I also prefer the original rather than analogues of the same drug. The principles of effectiveness are different, and there might be more side effects. I take Nolvadex only online, as I already trust the company, and they deliver it without any problems. I was afraid of side effects of Nolvadex, but, actually, I didn’t face them at all. I’ve been taking Nolvadex for a few months, and it has a good effect on me.
