Which consequence corresponds to penicillins having a well-established safety profile and being inexpensive?

• A. Efficacy
• B. Increased Healthcare Costs
• C. Antibiotic Resistance
• D. Safety & Cost

Answer: (D)

When an antibiotic has a long-standing, well-documented safety record and is inexpensive to produce, the most immediate practical outcomes are safety and cost. The established safety profile means that the vast majority of patients tolerate the drug well with manageable or rare adverse effects, which supports confident use across diverse populations and often reduces the need for extensive monitoring. The low cost makes the drug affordable for patients and healthcare systems, lowers barriers to access, and supports widespread use, including empiric therapy in common infections.

These two factors together explain why “Safety & Cost” is the best consequence. While efficacy is important, the question specifically ties to the established safety and cheapness, which point to safety considerations and cost implications rather than directly to how well the drug works or to resistance dynamics.
