Potentially fatal pancreatitis and hepatotoxicity, and severe peripheral neuropathy have been reported
in HIV-infected patients who received hydroxycarbamide in combination with first generation
antiretroviral medicinal products, particularly didanosine plus stavudine. Patients treated with
hydroxycarbamide in combination with didanosine, stavudine, and indinavir showed a median decline
in CD4 cells of approximately 100/mm3.

The possibility of interactions with other medicinal products administered concurrently should be
considered, particularly when the main route of elimination is active renal secretion via the organic
cationic transport system e.g. trimethoprim. Other medicinal products (e.g. ranitidine, cimetidine) are
eliminated only in part by this mechanism and were shown not to interact with lamivudine. The
nucleoside analogues (e.g. didanosine) like zidovudine, are not eliminated by this mechanism and are
unlikely to interact with lamivudine.
