Do not administer to patients with jaundice, hypersensitivity to rifamycins or history of severe haematological disorders (thrombocytopenia, purpura) during a previous treatment with rifamycins. Do not administer the weekly regimen to children under 2 years or the daily regimen to children under 13 years. Avoid or administer with caution to patients with hepatic disorders. May cause: harmless orange-red discoloration of body secretions (urine, tears, saliva, sputum, sweat, etc.); gastrointestinal disturbances; rarely, hepatotoxicity; headache, influenza-like symptoms; haematological disorders, cutaneous reactions (rash, pruritus) and hypersensitivity reactions (approximately 4% of patients). If signs of hepatotoxicity develop (e.g. jaundice), rifapentine should be discontinued until symptoms resolve. Rifapentine reduces the effect of many drugs (antimicrobials, anticonvulsants, some antiretrovirals, some hormones, antidiabetics, corticosteroids, direct-acting antivirals for chronic hepatitis C, warfarin, etc.): do not administer in patients on protease inhibitors or nevirapine; in women using contraceptive, use medroxyprogesterone or an intrauterine device; in the event of concomitant fluconazole administration, administer each drug 12 hours apart (rifapentine in the morning, fluconazole in the evening); for the other drugs, adjust dosage if necessary. Pregnancy and breast-feeding: not recommended (safety not established)
