Study Notes
- Antibiotic prophylaxis involves using antibiotics preventively to lower infection risk before it occurs.
- It does not treat existing infections, but it stops them from developing.
- The purposes of antibiotic prophylaxis include preventing infections after operations and protecting high-risk patients against severe bacterial infections.
Common Indications for Antibiotic Prophylaxis
- Surgical procedures, particularly clean-contaminated or contaminated surgeries like gastrointestinal, genitourinary, and orthopedic surgeries.
- Immunocompromised patients with conditions like neutropenia or HIV, or those undergoing chemotherapy require antibiotic prophylaxis.
- Antibiotics can stop infections from spreading, especially in high-risk individuals such as post-surgery patients or those with weak immune systems.
- Doxycycline, administered orally with light food, can be used to treat respiratory infections.
- Certain antibiotics like macrolides decrease inflammation and protect tissues and prevent bacteria from attaching to cells and reduce toxins.
