Administration
Nafcillin can be given either orally (UnipenĀ®) or by injection (NallpenĀ®)
Side effects
As with all penicillins, serious life-threatening allergic reactions can occur.
Milder side effects include:
- Nausea and vomiting
- Diarrhea, often due to suppression of normal gastrointestinal bacteria. Occasionally, this leads to a more serious super-infection with an organism like Clostridium difficile
- Abdominal pain
- Yeast infections (thrush) affecting the mouth and tongue or vagina
