Generic name: Hydroxyurea

Hydroxyurea capsules

HYDROXYUREA (Droxia®, Hydrea®) is used to treat sickle cell disease or certain types of cancer. Hydroxyurea is used for treating cancers of the blood, skin, ovary and head and neck. Hydroxyurea is also used to decrease the painful episodes associated with sickle cell disease. Hydroxyurea does not cure sickle cell disease, but may help to control the symptoms when used on a regular basis. Generic hydroxyurea capsules are available.

They need to know if you have any of these conditions:

• bleeding problems
• blood disorders
• dental disease
• having intramuscular injections
• infection (especially virus infection such as chickenpox or herpes)
• kidney disease
• an unusual or allergic reaction to hydroxyurea, other chemotherapy, other medicines, foods, dyes, or preservatives

Take hydroxyurea capsules by mouth. Follow the directions on the prescription label. Swallow the capsules with a drink of water. Do not take your medicine more often than directed. Finish the full course prescribed by your doctor or health care professional, even if the capsules make you feel unwell. Do not stop taking except on your prescriber's advice. If you have difficulty swallowing the capsule, carefully open it and empty the contents into a glass of water. Drink at once, some ingredients may not dissolve, but float on the surface; this does not matter. Make sure to drink all of the water to get the entire dose. Rinse and wash the glass thoroughly after using.

Hydroxyurea is a medicine that must be handled with care. People who are not taking hydroxyurea should not be exposed to the powder in the open capsules. Wear disposable gloves when handling bottles or capsule of hydroxyurea. Wash your hands before and after handling the hydroxyurea bottle or capsules. If the powder from the capsule is spilled, it should be wiped up immediately with a damp towel. The towel should then be put in a closed container such as a plastic bag and thrown away.

If you miss a dose, skip that dose unless you remember within a few hours, or your prescriber or health care professional tells you otherwise. Do not take double or extra doses. If you vomit after taking a dose, call your prescriber or health care professional for advice.

When given alone or with other chemotherapy agents, hydroxyurea may decrease your body's ability to fight infections or increase your risk to bruise or bleed.

Avoid taking aspirin, acetaminophen (Tylenol®), ibuprofen (Advil®), naproxen (Aleve®), or ketoprofen (Orudis® KT) products as these may hide a fever, unless instructed to by your prescriber or health care professional.

Be careful brushing and flossing your teeth or using a toothpick while receiving hydroxyurea because you may get an infection or bleed more easily. If you have any dental work done, tell your dentist you are receiving hydroxyurea.
