SPECIAL CONSIDERATIONS

Use with extreme caution in patients with severe Gr, neurologic, or blood disorders.

Use cautiously in patients with hepatic disease or alcoholism because drug concentrates in liver, and in those with G6PD deficiency or psoriasis because drug may exacerbate these conditions.

Alert: Drug dosage may be discussed in mg or mg-base; be aware of the difference.

Baseline and periodic ophthalmic examinations should be performed. Tests for ocular muscle weakness should periodically be checked after long-term use.

Patient should undergo audiometric examinations before, during, and aftertherapy, especially if therapy is long-term.

CBC and liver function studies should be monitored periodically during longterm therapy; if severe blood disorder not attributable to disease develops, drug may need to be discontinued.

Alert: Patient should be monitored for possible overdose, which can quickly lead to toxic signs or symptoms: headache, drowsiness, visual disturbances, CV collapse, and seizures, followed by cardiopulmonary arrest. Children are extremely susceptible to toxicity; long-term treatment should be avoided.
