Hydroxyurea or hydroxycarbamide (the latter being the recommended International Non-Proprietary Name), (brand names include Hydrea® and Droxia®) is an antineoplastic drug used in hematological malignancies. It is also used as an antiretroviral agent (e.g., against HIV).
500 milligrams once or twice a day, or more if pancytopenia does not develop.
Reported side-effects are: drowsiness, nausea, vomiting and diarrhea, constipation, mucositis, anorexia, stomatitis, bone marrow toxicity (which may take 7-21 days to recover after the drug has been discontinued), alopecia (hair loss), skin changes, abnormal liver enzymes, creatinine and blood urea nitrogen.
Due to its effect on the bone marrow, regular monitoring of the full blood count is vital, as well as early response to possible infections. In addition, renal function, uric acid and electrolytes, as well as liver enzymes, are commonly checked.
