What is this medication and its most common uses?Ticlopidine is a medicine used to help reduce the risk of stroke in people who have had a stroke or early stroke warning symptoms while being treated with aspirin, or for those who are intolerant or allergic to aspirin. Ticlopidine is also used in combination with aspirin for up to 30 days to reduce the risk of blood clots in stents placed in the heart to open blocked arteries.
What should I know when beginning and continuing on this medication?How does this medication work?
A stroke happens when a clot forms in a blood vessel in the brain or forms in another part of the body and breaks off, then travels to the brain. In both cases, the blood supply to part of the brain is blocked and that part of the brain is damaged. A heart attack or chest pain can happen when fatty deposits block the arteries that carry blood, oxygen, and nutrients to your heart. In this case, your healthcare provider may recommend the placement of a stent in your heart to decrease the chance of fatty deposits building up over time. Ticlopidine works by making platelets in the blood less sticky, so they are less likely to clump together and form blood clots.
What are the beneficial effects of this medication and when should I begin to have results?
What: Ticlopidine has been shown to reduce your risk of having a stroke or blood clots in your stent.
When: Everyone responds differently to treatment, so try to be patient and follow your healthcare provider's directions. It is important that you take ticlopidine exactly as your healthcare provider has prescribed.

What are the possible side effects of this medication?The following is not a full list of side effects. Side effects cannot be anticipated. If any develop or change in intensity, tell your healthcare provider as soon as possible. Only your healthcare provider can determine if it is safe for you to continue taking this medication.
Ticlopidine can cause a condition known as neutropenia (a decrease in the number of white blood cells that fight infection). Tell your healthcare provider immediately if you develop any signs of infection, including fever, chills, or sore throat.
Ticlopidine can cause thrombotic thrombocytopenic purpura (TTP) (a condition in which blood clots form in the blood vessels and can occur all over the body). Tell your healthcare provider immediately if you develop yellowing of your skin or the whites of your eyes, pinpoint dots on your skin, paleness, fever, weakness on a side of the body, or dark urine.
Rarely, ticlopidine can cause a condition known as aplastic anemia (a blood disorder in which the body's bone marrow doesn't make enough new blood cells). Tell your healthcare provider immediately if you develop excessive weakness and tiredness, paleness, bruising, or bleeding (such as from your nose or gums), or signs of an infection (such as fever).
These life-threatening blood problems occur most frequently during the first 3 months of treatment. Your healthcare provider will arrange for you to have blood tests before you start taking ticlopidine and then every 2 weeks for the first 3 months you are taking ticlopidine. If you stop taking ticlopidine for any reason within the first 3 months, you still need to have your blood tested for an additional 2 weeks after you stop taking ticlopidine.
More common side effects may include: diarrhea, nausea, indigestion, rash, stomach pain.
