PRECAUTIONS: Before taking this medication, tell your doctor or pharmacist if you are allergic to it; or to similar antiplatelet drugs (thienopyridines such as clopidogrel); or if you have any other allergies. This product may contain inactive ingredients, which can cause allergic reactions or other problems. Talk to your pharmacist for more details. Before using this medication, tell your doctor or pharmacist your medical history, especially of: current or past history of blood or immune disorders (thrombotic thrombocytopenic purpura, aplastic anemia, agranulocytosis, neutropenia), serious/active bleeding (such as bleeding stomach ulcers), bleeding/blood clotting disorders, liver disease, kidney problems. Before having surgery, tell your doctor or dentist about all the products you use (including prescription drugs, nonprescription drugs, and herbal products). Your doctor may instruct you to stop ticlopidine for 10 to 14 days before surgery. Follow your doctor's instructions carefully. This medication may cause stomach bleeding. Daily use of alcohol while using this medication will increase your risk for stomach bleeding. Limit alcoholic beverages. Ask your doctor or pharmacist about how much alcohol you may safely drink. Ticlopidine can make you more likely to get infections or may worsen any current infections. Therefore, wash your hands well to prevent the spread of infection. Avoid contact with people who have infections that may spread to others (such as chickenpox, measles, flu). Consult your doctor if you have been exposed to an infection or for more details. Do not have immunizations/vaccinations without the consent of your doctor. Avoid contact with people who have recently received live vaccines (such as flu vaccine inhaled through the nose). While you are taking this medication, it may take longer than usual for bleeding to stop if you have a cut or injury. To lower the chance of getting cut, bruised, or injured, use caution with sharp objects like razors and nail cutters, and avoid activities such as contact sports. Older adults may be at greater risk for bleeding while using this drug. During pregnancy, this medication should be used only when clearly needed. Discuss the risks and benefits with your doctor. It is unknown if this drug passes into breast milk, but it may have undesirable effects on a nursing infant. Consult your doctor before breast-feeding.

DRUG INTERACTIONS: Drug interactions may change how your medications work or increase your risk for serious side effects. This document does not contain all possible drug interactions. Keep a list of all the products you use (including prescription/nonprescription drugs and herbal products) and share it with your doctor and pharmacist. Do not start, stop, or change the dosage of any medicines without your doctor's approval. Some products that may interact with this drug include: mifepristone, other antiplatelet drugs (such as clopidogrel), cimetidine, antacids. Other drugs like this medication that affect blood clotting may increase your risk of bleeding. Examples are "blood thinners" (anticoagulants such as enoxaparin, heparin, warfarin). Follow your doctor's instructions carefully and continue your medications as directed. Tell your doctor right away if you notice unusual bleeding. Consult your doctor or pharmacist for more details. For certain conditions, you may be instructed by your doctor to take ticlopidine together with aspirin. Follow your doctor's instructions and continue aspirin as directed. If you are not currently taking aspirin, consult your doctor before starting it for any medical condition. Check the labels on all your medicines because they may contain aspirin or aspirin-like NSAIDs (such as ibuprofen, naproxen) that can increase the risk of bleeding. Ask your pharmacist about the safe use of those products.
