Nausea and vomiting, hair loss, and muscle or joint pain are some of the most commonly reported paclitaxel side effects. Those that occur rarely but are more serious include high or low blood pressure during an infusion, blood in the stool, and severe fluid retention or difficulty breathing.

An Introduction to Paclitaxel Side Effects

As with any medicine, side effects are possible with paclitaxel (Taxol^®); however, not everyone who takes the medication will experience side effects. In fact, most people tolerate it quite well. If side effects do occur, in most cases, they are minor and either require no treatment or can easily be treated by you or your healthcare provider.

(This article covers many, but not all, of the possible side effects with paclitaxel. Your healthcare provider can discuss a more complete list of paclitaxel side effects with you.)
