If allergic reactions such as rash or difficulty breathing occur after taking the medication, or if symptoms do not improve, prompt medical attention is recommended.

Amoxicillin is effective against common respiratory pathogens such as Streptococcus hemolyticus and Streptococcus pneumoniae, as well as urinary tract pathogens like Escherichia coli and Proteus mirabilis. It is commonly used to treat respiratory tract infections, urinary tract infections, and skin and soft tissue infections.

The drug is well absorbed orally and acts rapidly. However, it is a prescription medication and should not be taken with self-adjusted doses or extended duration. Misuse may lead to bacterial resistance and disrupt the normal microbial balance in the body, potentially causing gastrointestinal discomfort.

During amoxicillin treatment, it is essential to strictly follow medical instructions. Taking the medication after meals can reduce gastrointestinal irritation. Alcohol and alcoholic beverages should be avoided. Adequate fluid intake is important, and a light diet without spicy or greasy foods is recommended to prevent interference with drug efficacy.
