Metallic gallium is not toxic. However, several gallium compounds are toxic.

Gallium halide complexes can be toxic.<ref>{{cite journal |last1=Ivanoff |first1=C. S. |last2=Ivanoff |first2=A. E. |last3=Hottel |first3=T. L. |date=February 2012 |title=Gallium poisoning: a rare case report. |journal=Food Chem. Toxicol. |volume=50 |issue=2 |pages=212–5 |doi=10.1016/j.fct.2011.10.041 |pmid=22024274}}</ref> The Ga<sup>3+</sup> ion of soluble gallium salts tends to form the insoluble hydroxide when injected in large doses; precipitation of this hydroxide resulted in [[nephrotoxicity]] in animals. In lower doses, soluble gallium is tolerated well and does not accumulate as a poison, instead being excreted mostly through urine. Excretion of gallium occurs in two phases: the first phase has a [[biological half-life]] of 1 hour, while the second has a biological half-life of 25 hours.<ref name="Nordberg">{{cite book |first1=Gunnar F. |last1=Nordberg |first2=Bruce A. |last2=Fowler |first3=Monica |last3=Nordberg |title=Handbook on the Toxicology of Metals |publisher=Academic Press |pages=788–90 |edition=4th |date=7 August 2014 |isbn=978-0-12-397339-9}}</ref>
