TYGACIL®Drug Interactions (tigecycline)

7 DRUG INTERACTIONS

7.1 Warfarin

Prothrombin time or other suitable anticoagulation test should be monitored if TYGACIL is administered with warfarin [see Clinical Pharmacology (12.3)].

7.2 Calcineurin Inhibitors

Concomitant use of TYGACIL and calcineurin inhibitors such as tacrolimus or cyclosporine may lead to an increase in serum trough concentrations of the calcineurin inhibitors. Therefore, serum concentrations of the calcineurin inhibitor should be monitored during treatment with TYGACIL to avoid drug toxicity.

7.3 Oral Contraceptives

Concurrent use of antibacterial drugs with oral contraceptives may render oral contraceptives less effective.
