As hydroxyurea alters the function of DNA, there is a possibility that it may cause deformities in babies of pregnant women on the drug. Hydroxyurea is excreted in breast milk as well, and can have potentially serious side effects in infants, so new mothers should find an alternate method of feeding their babies. The side effects of hydroxyurea are related to the dose used. The most common side effect caused by this drug is bone marrow suppression. This can by monitored by doing regular blood tests to ensure that the levels of red blood cells, white blood cells, and platelets are within normal ranges.
Blood tests can also check for anemia.
Less serious, and less common, side effects include nausea, vomiting, diarrhea, constipation, anorexia, and drowsiness. As hydroxyurea is not officially approved for use in HIV in Canada, it may not be prescribed very often for this purpose. However, if you feel that you are a candidate for this drug, the best thing to do is to discuss it with your doctor or pharmacist. The manufacturer of Hydrea , Bristol Myers-Squibb, has set up a patient assistance program for people who need help accessing the drug. The phone number is available at the TIP office.
