Which of the following is a common adverse drug reaction associated with Amoxicillin?

Amoxicillin is a penicillin-type antibiotic commonly prescribed for various bacterial infections. Among its potential adverse drug reactions, diarrhea is a well-documented side effect. This occurs due to Amoxicillin's impact on the gut flora, which can disrupt the balance of beneficial bacteria, leading to gastrointestinal symptoms such as diarrhea.

While rash, dizziness, and liver toxicity can occur with antibiotics, they are less common with Amoxicillin specifically. Rash may be related to allergic reactions or hypersensitivity but is not as prevalent as gastrointestinal effects. Dizziness is not typically associated with Amoxicillin, and liver toxicity is more rare, especially in comparison to the common occurrence of diarrhea. Thus, the significant incidence of diarrhea in patients taking Amoxicillin makes it the most notable adverse reaction associated with this medication.
