ADVERSE REACTIONS
Sickle Cell Anemia
In patients treated for sickle cell anemia in the Multicenter Study
of Hydroxyurea in Sickle Cell Anemia,1 the most
common adverse reactions were hematologic, with neutropenia, and low reticulocyte
and platelet levels necessitating temporary cessation in almost all patients.
Hematologic recovery usually occurred in two weeks.
Non-hematologic events that possibly were associated with treatment
include hair loss, skin rash, fever, gastrointestinal disturbances, weight
gain, bleeding, and parvovirus B-19 infection; however, these non-hematologic
events occurred with similar frequencies in the hydroxyurea and placebo treatment
groups. Melanonychia has also been reported in patients receiving DROXIA for SCA.
Other
Adverse events associated with the use of hydroxyurea in the treatment
of neoplastic diseases, in addition to hematologic effects include: gastrointestinal
symptoms (stomatitis, anorexia, nausea, vomiting, diarrhea, and constipation),
and dermatological reactions such as maculopapular rash, skin ulceration,
dermatomyositis-like skin changes, peripheral erythema, and facial erythema.
Hyperpigmentation, atrophy of skin and nails, scaling, and violet papules
have been observed in some patients after several years of long-term daily
maintenance therapy with hydroxyurea. Skin cancer has been reported. Cutaneous
vasculitic toxicities, including vasculitic ulcerations and gangrene, have
occurred in patients with myeloproliferative disorders during therapy with
hydroxyurea. These vasculitic toxicities were reported most often in patients
with a history of, or currently receiving, interferon therapy (see
WARNINGS). Dysuria and alopecia have been reported. Large doses may produce drowsiness. Neurological disturbances
have occurred and were limited to headache, dizziness, disorientation, hallucinations, and convulsions. Hydroxyurea may cause temporary
impairment of renal tubular function accompanied by elevations in serum uric acid, blood urea nitrogen (BUN), and creatinine levels. Abnormal bromsulphalein (BSP) retention has been reported. Fever, chills, malaise, edema, asthenia, and elevation of hepatic enzymes have also been reported.
The association of hydroxyurea with the development of acute pulmonary reactions consisting of diffuse pulmonary infiltrates, fever, and dyspnea
has been reported. Pulmonary fibrosis also has been reported.
In HIV-infected patients who received hydroxyurea in combination with antiretroviral agents, in particular, didanosine plus stavudine, fatal and nonfatal pancreatitis and hepatotoxicity, and severe peripheral neuropathy have been reported. Patients treated with hydroxyurea in combination with didanosine,
stavudine, and indinavir in Study ACTG 5025 showed a median decline in CD4 cells of approximately 100/mm3. (See
