Why are penicillins and cephalosporins not supposed to be used with bacteriostatic agents?
Why are penicillins and cephalosporins not supposed to be used with bacteriostatic agents?
- They lose their antibiotic activity
- They become toxic to the body
- They may cause allergic reactions
- They may antagonize the effects of each other (correct)

Why can cephalosporins be used with some patients allergic to penicillins?
- Cephalosporins have a different mode of action than penicillins (correct)
- The allergic reactions to penicillins are usually mild
- Cephalosporins do not contain beta-lactam rings
- Cephalosporins have lower antigenic potential than penicillins

Penicillin/Cephalosporin Allergy
Penicillin/Cephalosporin Allergy
4-15% of penicillin-allergic patients also have a cephalosporin allergy.
Antibiotic antagonism
Antibiotic antagonism
Penicillins and cephalosporins shouldn't be used with bacteriostatic agents because they can counteract each other's effects.
Cephalosporin Use in Penicillin Allergy
Cephalosporin Use in Penicillin Allergy
Cephalosporins have a different mechanism of action than penicillins, allowing some patients allergic to penicillins to tolerate cephalosporins.

Study Notes
Antibiotic Allergies and Interactions
- Approximately 10% of patients allergic to penicillins are also allergic to cephalosporins.
- Penicillins and cephalosporins should not be used with bacteriostatic agents, as they can interfere with the bactericidal effects of these antibiotics.
Cephalosporins and Penicillin Allergies
- Cephalosporins can be used with some patients allergic to penicillins, as they have a different side chain and are less likely to cross-react.
Antibiotic Prophylaxis in Dentistry
- The scientific rationale for antibiotic prophylaxis in dentistry is to prevent bacterial endocarditis and other infections in susceptible patients.
- The main concern addressed by antibiotic prophylaxis in dentistry is the risk of infection, particularly in patients with pre-existing heart conditions, prosthetic joints, or compromised immune systems.
Infection Types
- The term used to describe infection in a confined region from which pathogens travel to other regions of the body is metastatic infection.
