      <study_design>Randomization: Randomized, Blinding: Double blinded, Placebo: Used, Assignment: Parallel, Purpose: Treatment, Randomization description: In this study, randomization is performed using block generation method and Random Allocation software.
Random Allocation software provides a table of 140 in which our two groups, groups A and B, are each repeated 70 times randomly to minimize the possibility of biased intervention. Each cell in this table is called a block. There will be one patient in each block and the therapist will refer the patients who meet the inclusion criteria to the pharmacy and the patients will be placed in the random blocks of the above table, respectively, Blinding description: This study will be a double-blind study using placebo. Therefore, in order to blind in this study, patients, laboratory technicians, therapist who will be responsible for the activity of prescribing drugs, receiving samples and completing a questionnaire, as well as the researcher responsible for evaluating the results and statistical analyzer will be blind to patient allocation, and will not know which patient is in the intervention and which patient is in the control group. The main researcher will not be blind to the groups and will prepare the drugs and placebo in two packages A and B and place them in the pharmacy with the pharmacist.</study_design>

      <i_freetext>Intervention 1: Intervention group: In the intervention group, in addition to receiving the national standard treatment, patients will receive oral vitamin A 25,000 international units (Zahravi-Iran) per day for 10 days. Intervention 2: Control group: In the control group, patients receive only the national standard treatment with an oral placebo similar to the main drug, once a day for 10 days.</i_freetext>
