H371: May cause damage to organs (systemic toxicity)
P307+P311: IF exposed: Call a POISON CENTER or doctor/physician.
P260: Do not breathe dust/fume/gas/mist/vapours/spray.

In Physicians' Desk Reference (PDR 64 edition (2010)), there are reports of nausea, vomiting, myelosuppression (decreased white blood cell count and platelet count) in the section on Common Side Effects. Based on the data, the substance was classified into Category 1 (bone marrow). In addition, there are reports of fatigue, sores in mouth or on lips, feeling disoriented, difficulty walking, blurred vision, change in vision, liver and kidney problems, and scarring of lung tissue in the section on Rare Side Effects. Since it is unclear whether they are acute effects, the substance was classified into Category 2 (systemic toxicity).

Warning
H372: Cause damage to organs through prolonged or repeated exposure (bone marrow)
H373: May cause damage to organs through prolonged or repeated exposure (liver, kidney, lung, nervous system)
P260: Do not breathe dust/fume/gas/mist/vapours/spray.
P264: Wash ... thoroughly after handling.
P270: Do not eat, drink or smoke when using this product.
P314: Get medical advice/attention if you feel unwell.

In addition, there are reports of fatigue, sores in mouth or on lips, feeling disoriented, difficulty walking, blurred vision, change in vision, liver and kidney problems, and scarring of lung tissue in the section on Rare Side Effects. Since it is unclear whether they are secondary effects, the substance was classified into Category 2 (liver, kidney, lung, nervous system).
