Reviews

Almost all the reviews on the Internet about the antibiotic amoxicillin are positive. Patients note the rapid effect of taking the drug, ease of use (the reception does not depend on the time of eating), full recovery from existing diseases at the end of the course of treatment.

A small percentage of negative reviews in which patients complain that the drug "did not help" is due to the fact that amoxicillin, although it is a broad-spectrum antibiotic, is not omnipotent, and not all bacteria are sensitive to its action. Therefore, it is recommended to conduct an examination of the patient before prescribing this antibiotic: isolate the pathogen and check its sensitivity to the drug. But these studies require a fairly long time, and are usually conducted in a stationary environment. In practice, however, the doctor, seeking to alleviate the condition of the patient, prescribes treatment without examination, in part "at random", and sometimes mistakes. The sick, however, consider the absence of the effect of treatment as a lack of a drug - this opinion is incorrect.
