Hydroxyurea is a commonly prescribed oral medicine used mainly for sickle cell disease and certain blood disorders like polycythemia vera and essential thrombocythemia. It isn’t a quick fix; it’s meant to lower complications over time. For people with frequent sickle cell pain or low blood counts, hydroxyurea can cut crisis frequency and hospital visits.
The drug boosts fetal hemoglobin (HbF) in red blood cells. More HbF means fewer sickled cells, which reduces pain episodes and organ damage. For blood disorders, it helps control high counts that cause clotting or bleeding risks.
Dosing varies. Doctors usually start low and slowly increase the dose until the desired effect or mild side effects appear. Common starting doses are weight-based. Take it at about the same time every day. If you miss a dose, follow your prescriber's rule — usually skip and take the next scheduled dose; don’t double up without advice.
The most important risk is bone marrow suppression. That can show up as low white blood cells, platelets, or red cells. Your doctor will order regular blood tests—often every 2–4 weeks when starting or changing dose, then every 4–12 weeks once stable. Stick to that schedule; it’s how problems are caught early.
Other side effects can include nausea, mouth sores, skin changes, or hair thinning. If you get a fever, unusual bruising, persistent vomiting, or signs of infection, contact your healthcare team right away. Those symptoms can mean your blood counts have dropped too low.
Pregnancy and breastfeeding: hydroxyurea can harm a fetus. People who can become pregnant should use reliable birth control and discuss timing with their doctor. Men concerned about fertility should talk to their provider before treatment—sperm changes are possible.
Drug interactions and vaccines: hydroxyurea can lower blood counts, so live vaccines may be risky if your counts are very low. Always tell any provider or pharmacist you’re taking hydroxyurea before getting new medicines or vaccines.
Practical tips: store pills at room temperature and keep them in their original container. Wash your hands after handling capsules if they’re broken. Take the medication with water and food if it upsets your stomach. Keep a calendar or phone reminder so you don’t miss doses. Carry a note or card that says you take hydroxyurea in case of emergency.
Questions to ask your doctor: How often will I need blood tests? What signs should make me call right away? Is this likely to help my condition and for how long? Getting clear answers helps you use hydroxyurea safely and confidently.
If you need more detailed guidance based on your condition or symptoms, check in with a hematologist or your prescribing clinician. They can tailor monitoring and dose changes to your situation.
