Interactions between your drugs

Major

PACLitaxel atazanavir

Applies to: paclitaxel and atazanavir

Talk to your doctor before using PACLitaxel together with atazanavir. Combining these medications may significantly increase the blood levels of PACLitaxel.

You may also be more likely to develop anemia, bleeding problems, or infections due to low blood cell counts. Your doctor may be able to prescribe alternatives that do not interact, or you may need a dose adjustment or more frequent monitoring to safely use both medications. You should contact your doctor if you develop paleness, fatigue, dizziness, fainting, unusual bruising or bleeding, fever, chills, diarrhea, sore throat, muscle aches, shortness of breath, blood in phlegm, weight loss, red or inflamed skin, body sores, and pain or burning during urination.
