Description
Hydrea 500 mg is a prescription medicine containing hydroxyurea. It belongs to a group of medicines called antimetabolites. Doctors use hydroxyurea for certain blood cancers and other specific medical conditions. The appropriate use depends on the diagnosis, treatment plan, and medical assessment.
Hydrea 500 mg is taken by mouth as a capsule. It requires careful monitoring because it can affect blood cells and cause other important side effects. Your doctor may request regular blood tests and adjust your treatment according to your response and laboratory results.

Important: Hydrea 500 mg is not suitable for self-medication. Use it only when prescribed by a qualified medical professional.
Key Benefits
Hydrea 500 mg may offer the following treatment-related benefits when prescribed appropriately:
- Supports treatment of certain approved medical conditions.
- Provides hydroxyurea in an oral capsule form.
- Allows doctors to individualize treatment according to the patient’s condition.
- Can be included in specialist-directed treatment plans.
These are treatment characteristics, not guarantees of individual results. Your doctor decides whether hydroxyurea is appropriate for you.
Active Ingredients
The active ingredient in Hydrea 500 mg is hydroxyurea.
Hydroxyurea is the generic name. Hydrea is the brand name associated with this medicine. The 500 mg strength refers to the amount of hydroxyurea in each capsule.
Some capsule formulations also contain inactive ingredients. These may vary by manufacturer and product presentation. Check the medicine packaging and official product information for the exact ingredients of your supplied product.
How Hydrea 500 mg Works
Hydroxyurea works by interfering with DNA synthesis. It inhibits an enzyme called ribonucleotide reductase. This enzyme is needed to produce the building blocks used to make DNA.
By reducing DNA synthesis, hydroxyurea can slow the growth of certain rapidly dividing cells. This action helps explain its role in selected cancer treatment plans.
Hydroxyurea may also affect normal blood-forming cells. This is one reason doctors monitor blood counts during treatment.
The way Hydrea works does not mean it treats every cancer. Its approved indications and other specialist-directed uses depend on the medical condition and treatment plan.
Indications and Uses
What is Hydrea 500 mg used for?
The official US prescribing information lists Hydrea for:
- Resistant chronic myeloid leukemia.
- Locally advanced squamous cell carcinoma of the head and neck, excluding the lip, in combination with concurrent chemoradiation.
These are the indications listed in the referenced US label. Treatment decisions depend on the patient’s diagnosis and the prescribing clinician’s assessment.
Chronic Myeloid Leukemia
Chronic myeloid leukemia, or CML, is a blood cancer involving abnormal white blood cells. Hydrea may be used in selected patients with resistant CML.
The choice of treatment depends on disease status, previous treatment, and current medical guidance. Your specialist will determine whether hydroxyurea is appropriate.
Head and Neck Squamous Cell Carcinoma
Hydrea is also indicated in the US label for locally advanced squamous cell carcinoma of the head and neck, excluding the lip, when used with concurrent chemoradiation.
This is a specific treatment setting. Hydrea should not be considered a general treatment for every head and neck cancer.
Dosage & Administration
Take Hydrea 500 mg exactly as prescribed by your doctor.
The correct dose depends on factors such as:
- Medical condition.
- Treatment response.
- Other medicines being used.
- Kidney function.
- Blood counts.
- Previous treatment and risk factors.
The official prescribing information states that the dose should be individualized. It also provides specific dose-adjustment guidance for patients with reduced kidney function.
How to Take Hydrea 500 mg
Follow the instructions provided by your prescriber and pharmacist.
- Take the medicine according to your prescribed schedule.
- Swallow the capsule whole unless your prescriber gives specific alternative instructions.

Kidney Function and Dose Adjustment
Hydroxyurea dosing may require adjustment when kidney function is reduced. The US Hydrea label specifies a 50% dose reduction for patients with creatinine clearance below 60 mL/min.
This does not mean every patient should use the same reduced dose. The prescribing clinician must determine the correct regimen.
