HYDREA is a medication that must be handled with care. People who are not taking HYDREA should not be exposed to it. If the powder from the capsule is spilled, it should be wiped up immediately with a damp disposable towel and discarded in a closed container, such as a plastic bag. The medication should be kept away from children and pets.
Prospective studies on the potential for hydroxyurea to interact with other drugs have not been performed.
Concurrent use of hydroxyurea and other myelosuppressive agents or radiation therapy may increase the likelihood of bone marrow depression or other adverse events.
Since hydroxyurea may raise the serum uric acid level, dosage adjustment of uricosuric medication may be necessary.
Hydroxyurea is contraindicated in patients with marked bone marrow depression, i.e., leukopenia (<2500 WBC) or thrombocytopenia (<100,000), or severe anemia.
HYDREA is contraindicated in patients who have demonstrated a previous hypersensitivity to hydroxyurea or any other component of its formulation.
