GENERIC AVAILABLE: no
PREPARATIONS: Capsules: 250 mg.
STORAGE: The capsules should be kept at room temperature, 15 C to 30 C (59 F to 86 F).

DRUG INTERACTIONS: Administering salicylic acid derivatives with low molecular weight heparins (for example, enoxaparin) used as blood thinners may increase the risk of bleeding after neuraxial anesthesia (local anesthesia with anesthetics that are injected around nerves). Olsalazine may increase the effect of warfarin (Coumadin), a blood thinner, and cause bleeding. Administering olsalazine with 6-mercaptopurine or thioguanine may increase the risk of bone marrow suppression, resulting in decreased blood cells.
PREGNANCY: It is not known whether olsalazine crosses the placenta to the fetus.
NURSING MOTHERS: Mesalamine, which is the active form of olsalazine, may be secreted into breast milk and cause diarrhea in the infant.
