Droxia (hydroxyurea) is an antimetabolite that affects certain cells in the body, such as cancer cells or sickled red blood cells, used to treat melanoma (a type of skin cancer), chronic myelocytic leukemia, cancer of the ovary, and primary squamous cell (skin) cancer of the head and neck. Droxia is also used to treat sickle cell anemia. Common side effects of Droxia include nausea, vomiting, loss of appetite, mouth sores, diarrhea, constipation, hair loss, skin peeling or discoloration, mild rash, upset stomach, headache, dizziness, drowsiness, or weight gain.

Dosage of Droxia is based on weight, medical condition, laboratory test results, and response to treatment. The initial dose of Droxia is 15 mg/kg/day as a single dose. Treatment may be stopped for a short time if blood counts are too low. Other drugs may interact with Droxia. Tell your doctor all medications and supplements you use. Droxia is not recommended for use during pregnancy. It may harm a fetus. Discuss birth control with your doctor. If you become pregnant or think you may be pregnant, tell your doctor.

SIDE EFFECTS

The following adverse reactions are described in detail in other labeling sections:

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.

Clinical Trial Experience

In 299 patients treated for sickle cell anemia in the Multicenter Study of Hydroxyurea in Sickle Cell Anemia, 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.

Other adverse reactions include hair loss, macrocytosis, bleeding, and melanonychia.

Postmarketing Experience

The following adverse reactions have been identified during postapproval use of hydroxyurea in the treatment of neoplastic diseases. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency.
