Amoxicillin capsule is a penicillin antibiotic with a wide antibacterial spectrum. It can be used clinically for infections caused by some bacteria, such as upper respiratory tract infections caused by hemolytic streptococcus and pneumonia streptococcus. It can also be used for urinary tract infection caused by Escherichia coli, Proteus mirabilis, etc. In addition, it can also be used for skin and soft tissue infections and lower respiratory tract infections. The usage of amoxicillin capsules is 0.5g once, once every 6 to 8 hours, and the daily dose should not exceed 4g. We should note that amoxicillin capsules can be taken one to two hours after meals, which can reduce the irritation to the gastrointestinal tract. In addition, when taking amoxicillin capsules, you should also pay attention to the penicillin skin test before taking it. If the penicillin skin test is positive, it should be prohibited. Also note that if amoxicillin capsules are taken for a long time, the liver and kidney functions must be checked regularly to avoid damage to the liver and kidney functions.
