Patient/Family Teaching ⬆ ⬇

Instruct patient to take medication exactly as directed; do not skip or double doses. Take missed dose as soon as possible except if next dose is almost due.

Caution patient to use sunscreen and protective clothing to prevent photosensitivity reactions.
Instruct patient to report symptoms of leukopenia (fever, sore throat, signs of infection); thrombocytopenia (bleeding gums; bruising; petechiae; blood in stools, urine, or emesis); or gold toxicity immediately. Diarrhea may be resolved by ↓ the dose.
Emphasize the importance of regular visits to health care professional to monitor progress and evaluate blood and urine tests for side effects.
