Zyvox Side Effects

Common Side Effects in Children

The side effects of Zyvox may be slightly different in children compared to adults. Just like in adults, Zyvox has been studied in clinical trials in children, ranging in age from birth to 17 years old. In these studies, one group of children received Zyvox, while another group was given a different antibiotic.
In these studies, the most common Zyvox side effects in children included:
  • Fever -- in up to 14.1 percent of children
  • Diarrhea -- up to 10.8 percent
  • Vomiting -- up to 9.4 percent.
  • Skin rash -- up to 7.0 percent
  • Headache -- up to 6.5 percent.
Other common reactions (occurring in 2 to 5 percent of children) included:
  • Upper respiratory tract infections
  • Nausea
  • Loose stools
  • Shortness of breath
  • Irritation or skin reaction at the site of injection (with the intravenous [IV] form)
  • Sore throat
  • Cough
  • Abdominal pain (stomach pain)
  • Generalized swelling.
