Levofloxacin hydrochloride tablets are still very well absorbed orally, and the absorption rate can be close to 100%. The normal adult dosage, if it is a respiratory tract infection, such as bronchitis or pneumonia, is 0.1g 3 times a day, or 0.2g twice a day, for a total of 0.3-0.4g per day. In case of bacterial prostatitis, 2 times a day, 0.2 g. However, it is important to confirm that it is bacterial prostatitis before using it, as most prostatitis is non-bacterial. The total amount for a normal adult is 0.3-0.4g in 2-3 times a day; in case of severe infection it can be increased to 0.2g in 1 time, 3 times a day for a total of 0.6g per day.
