Riborea contains Hydroxyurea.

Product Overview

Riborea is a medication containing the active ingredient Hydroxyurea. It is an oral chemotherapy drug that works by interfering with the growth and spread of cancer cells in the body. Riborea is available in capsule form for oral administration.


Riborea is primarily used in the treatment of certain types of cancer, including chronic myeloid leukemia (CML), essential thrombocythemia, and polycythemia vera. It may also be prescribed to treat sickle cell anemia, a genetic blood disorder. Riborea works by inhibiting the activity of an enzyme called ribonucleotide reductase, which is involved in DNA synthesis. By disrupting DNA replication and cell division, Riborea helps slow down or stop the growth of cancer cells.

How to Use

Riborea capsules should be taken orally with a full glass of water. It is usually taken once daily on an empty stomach, at least one hour before or two hours after a meal. The dosage and duration of treatment depend on the type and stage of cancer being treated, as well as the patient’s overall health and response to therapy. Follow your doctor’s instructions carefully and do not crush, chew, or open the capsules.

How it Works

Hydroxyurea, the active ingredient in Riborea, works by inhibiting the activity of ribonucleotide reductase, an enzyme involved in DNA synthesis. By blocking this enzyme, Riborea interferes with the production of DNA building blocks, thereby disrupting the replication and division of cancer cells. This leads to the suppression of tumor growth and the eventual death of cancer cells.

Dosage and Administration

The dosage of Riborea varies depending on the type of cancer being treated and the patient’s individual factors such as age, weight, and overall health. Your doctor will determine the appropriate dosage and duration of treatment for your condition. It is important to take it exactly as prescribed and to not miss any doses. Do not adjust your dosage without consulting your doctor.

Common Side Effects

Common side effects of Riborea may include nausea, vomiting, diarrhea, loss of appetite, and mild skin rash. These side effects are usually temporary and may improve with continued use. However, if they persist or worsen, inform your doctor. It may also cause more serious side effects such as bone marrow suppression, which can lead to anemia, leukopenia, or thrombocytopenia. Contact your doctor immediately if you experience signs of infection, unusual bruising or bleeding, or severe fatigue.


Riborea should not be used in pregnant women, as it may cause harm to the unborn baby. Use effective birth control to prevent pregnancy while taking it, and inform your doctor if you become pregnant during treatment. Riborea may also cause dizziness or drowsiness. Avoid driving or operating heavy machinery until you know how it affects you. Inform your doctor about all medications, supplements, and medical conditions before starting it.
