Nafcillin FAQs
What is nafcillin used to treat?

Nafcillin is used to treat infections caused by certain types of bacteria, particularly Staphylococcus aureus. It is commonly used for skin and soft tissue infections, bone and joint infections, and endocarditis when the bacteria are resistant to penicillin but sensitive to nafcillin.

Nafcillin and penicillin are both antibiotics, but they differ in their spectrum of activity and resistance to certain bacterial enzymes. Nafcillin is a penicillinase-resistant penicillin, meaning it is effective against bacteria that produce the enzyme penicillinase, which can inactivate penicillin. This makes nafcillin particularly useful for treating infections caused by penicillinase-producing strains of Staphylococcus aureus. In contrast, penicillin is not resistant to penicillinase and is generally used for infections caused by non-penicillinase-producing bacteria.

Nafcillin is primarily administered intravenously (IV), but it can also be given intramuscularly (IM) in certain cases. However, the IV route is more commonly used for its effectiveness in treating serious infections.

Nafcillin is primarily effective against Gram-positive bacteria, particularly Staphylococcus aureus, including penicillinase-producing strains. It is not effective against methicillin-resistant Staphylococcus aureus (MRSA) or Gram-negative bacteria.

Penicillin is commonly used to treat bacterial infections such as strep throat, syphilis, and pneumonia.
