Due to reports of interferon alpha exacerbating pre-existing psoriatic disease and sarcoidosis, use of IntronA in patients with psoriasis or sarcoidosis is recommended only if the potential benefit justifies the potential risk.
Kuna psoriaasi ja sarkoidoosi põdevatel haigetel on kirjeldatud interferoon alfa toimel haiguse ägenemist, on IntronA kasutamine soovitatav vaid juhtudel, kus oodatav kasu õigustab potentsiaalset riski.
