Side Effects of Zalcitabine

During extensive clinical trials studying the side effects of zalcitabine, unusual sensations (like numbness, burning, or tingling) were reported the most often. Other common side effects included nausea, fatigue, and headaches. Some side effects of zalcitabine should be reported immediately to your healthcare provider, including unusual bruising or bleeding, seizures, and frequent infections.

 

Side Effects of Zalcitabine: An Introduction

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