Quick Answer: What Is Hydroxyurea?
Hydroxyurea (also called hydroxycarbamide) is an oral chemotherapy medicine that slows the overproduction of blood cells. Its main uses are chronic myeloid leukemia (CML), essential thrombocythemia, polycythemia vera, and — at different dosing — reducing painful crises in sickle cell disease. This 500mg, 100-capsule pack is an oral medicine taken at home, but every aspect of dosing, blood monitoring, and duration is set by your treating hematologist or oncologist based on regular blood counts. Never adjust the dose yourself.

How Hydroxyurea Works
Hydroxyurea blocks ribonucleotide reductase, an enzyme cells need to make the DNA building blocks required for division. Blood-forming cells in the bone marrow divide rapidly and constantly, which is exactly why an overactive bone marrow (as in CML, essential thrombocythemia, or polycythemia vera) responds so well to this mechanism — the drug slows the excessive cell production at its source. In sickle cell disease, hydroxyurea works through a related but distinct mechanism: it boosts fetal hemoglobin production, which interferes with the sickling process and meaningfully reduces painful crises and hospitalizations.
Taking Hydroxyurea Safely at Home
- Take exactly as your hematologist/oncologist prescribes — dose is calculated by body weight and blood count results, and changes based on regular lab monitoring.
- Handle with gloves when touching the capsules directly; if a capsule breaks or opens, avoid contact with the powder and clean the area as instructed by your pharmacist — hydroxyurea is a cytotoxic medicine even in oral form.
- Swallow capsules whole with water; do not open or crush them.
- Take at the same time daily for consistency, with or without food as your doctor advises.
- Keep every blood-count appointment — these determine whether your dose continues, increases, decreases, or pauses.
What Regular Monitoring Looks For
Complete blood counts track white cells, platelets, and hemoglobin — hydroxyurea’s main effect and main risk is on these same cell lines it’s designed to control. Your specialist adjusts the dose to keep counts in a safe therapeutic range: enough to control the underlying disease, not so much that healthy blood production is suppressed dangerously. This is why appointments cannot be skipped even when you feel completely well.
Possible Side Effects
Common: mild nausea, skin changes (darkening, nail changes), and mouth sores — usually manageable and often improve with dose adjustment. Important to report promptly: unusual bruising or bleeding, fever, mouth ulcers that won’t heal, or unusual fatigue — these can signal blood counts have dropped too low and need same-day medical attention. Long-term use requires periodic skin checks, as hydroxyurea is associated with an increased risk of certain skin cancers with prolonged use — sun protection is a standing recommendation.
Important Precautions
- Pregnancy: It can harm a developing fetus — effective contraception is essential during treatment for both men and women, and pregnancy plans must be discussed with your specialist well in advance.
- Kidney and liver function are monitored alongside blood counts, as both affect how the drug is processed.
- Live vaccines should be avoided during treatment — check with your specialist before any vaccination.
- Avoid direct skin contact with the medicine; caregivers should use gloves when handling.
Storage and Handling
Store below 25°C, in the original container, away from children and other household members — cytotoxic medicines require dedicated, clearly labeled storage separate from other family medicines.

Expert Note
“It is one of the quieter success stories in hematology — a decades-old oral medicine that still meaningfully reduces sickle cell crises and controls myeloproliferative disorders. The patients who do best treat their blood-count appointments as non-negotiable, because this drug’s safety margin lives entirely in that regular monitoring.” — Dr. Abdallah Fouad, Clinical Nutrition Specialist, 25+ years of pharmaceutical experience.
Frequently Asked Questions About Hydroxyurea
Do I need to handle the capsules with gloves?
Direct skin contact should be minimized as a precaution since it’s a cytotoxic medicine; avoid opening or crushing capsules, and wash hands after handling.
What if I develop mouth sores or skin darkening?
These are recognized, often manageable side effects — report them to your specialist, who may adjust the dose or suggest supportive care.
Can I skip a blood test if I feel fine?
No — hydroxyurea’s effect on blood counts can occur without symptoms; regular monitoring is how your specialist keeps treatment both effective and safe.
Is hydroxyurea safe during pregnancy?
No — it can harm a developing fetus. Effective contraception is essential during treatment, and pregnancy planning must be discussed with your specialist in advance.
Why does long-term use need skin checks?
Hydroxyurea is associated with increased skin cancer risk with prolonged use; sun protection and periodic dermatology checks are standard precautions.
