Drug Interactions With Paclitaxel

A number of medications may cause drug interactions with paclitaxel, including rifamycin antibiotics, protease inhibitors, and certain anticonvulsants. These interactions can increase the level of paclitaxel in your blood and increase your risk of developing potentially negative side effects. If drug interactions with paclitaxel are a concern, your healthcare provider may advise you to avoid certain medications or adjust your dosages.
