      <study_design>Randomization: Randomized, Blinding: Double blinded, Placebo: Used, Assignment: Parallel, Purpose: Treatment, Other design features: This clinical trial is double blind and neither the patients nor the researchers know who belongs to the placebo arm and who belongs to the Acyclovir arm. Randomization method is block randomization. Only after all the data have been recorded do the researchers learn which individuals are which.   In this way researchers will not be biased in their assessment of patients response to the treatment given. Patients in Acyclovir arm will receive Acyclovir 400 mg pills (Zovirax), and the placebo in this study mainly consists of calcium phosphate and Avicel (microcrystalline cellulose ).&#13;
Placebo and Acyclovir pills used in this study are all provided by Farabi Pharmaceutical Company and will be handed to patients in similar pill bottels.</study_design>
      <phase>2-3</phase>
      <hc_freetext>Meniere's disease.</hc_freetext>
      <i_freetext>Intervention 1: Participants who are randomly placed in placebo group, besides having a low salt diet will take the placebo pills (inert ingredient) for 10 days 5 times a day, then 3 times a day for next 10 days, and 2 times a day for the last 10 days. &#13;
Patients would receive the medication in 2 sessions, first in the beginning of the study and the rest after 10 days. This would increase their compliance, and physicians would be aware of possible complications. &#13;
Patients will report changes in their symptoms 10 days after initiating the drug and one month, three months and six months after the treatment.  All changes in frequency and duration of vertigo attacks are recorded, and tinnitus and aural fullness is recorded in a 0(with no symptom) to 4 (very severe)  scale. Intervention 2: Patients who were randomly allocated to the   Acyclovir group besides having low salt diet will take the Acyclovir 400 mg pills (Zovirax) for 10 days 5 times a day, then 3 times a day for next 10 days, and 2 times a day for the last 10 days. Patients would receive the medication in 2 sessions, first in the beginning of the study and the rest after 10 days.
