In clinical trials, 2514 patients were treated with tigecycline (the active ingredient contained in Tygacil) In comparative trials, serious side effects related to infection were reported more often in patients treated with tigecycline (7%) versus comparators (6%), with sepsis/septic shock reported in 2% and 1% of patients treated with tigecycline and comparator drugs, respectively. The most common side effects were nausea and vomiting which usually occurred within the first 2 days of treatment.
