Hydroxyurea 500mg Uses

How Does Hydroxyurea 500mg Work?

Hydroxyurea 500mg works through different mechanisms depending on the condition being treated:

• For Cancer: It inhibits DNA synthesis in rapidly dividing cells, slowing their growth and progression.
• For Sickle Cell Disease: It increases the production of fetal hemoglobin (HbF), which reduces the sickling of red blood cells and prevents blockages in blood vessels.

These mechanisms help control disease progression, reduce symptoms, and minimize complications.
