Cilostazol
What is CILOSTAZOL?
(CILOSTAZOL) Cilostazol is used to improve the symptoms of a certain blood flow problem in the legs (intermittent claudication). Cilostazol can decrease the muscle pain/cramps that occur during exercise/walking. Claudication pain is caused by too little oxygen getting to the muscles. Cilostazol can increase blood flow and the amount of oxygen that gets to the muscles. Cilostazol is an antiplatelet drug and a vasodilator. It works by stopping blood cells called platelets from sticking together and prevents them from forming harmful clots. It also widens blood vessels in the legs. Cilostazol helps the blood to move more easily and keeps blood flowing smoothly in your body.
How should I use CILOSTAZOL?
Read the Patient Information Leaflet if available from your pharmacist before you start taking cilostazol and each time you get a refill. If you have any questions, ask your doctor or pharmacist. Take this medication by mouth without food as directed by your doctor, usually twice daily, at least 30 minutes before or 2 hours after breakfast and dinner. The dosage is based on your medical condition, response to treatment, and other medications you may be taking. Be sure to tell your doctor and pharmacist about all the products you use (including prescription drugs, nonprescription drugs, and herbal products). Use this medication regularly to get the most benefit from it. Remember to use it at the same times each day. Your symptoms may improve in 2-4 weeks, but it may take up to 12 weeks before you get the full benefit of this drug. Tell your doctor if your condition lasts or gets worse.
What should I tell my health care provider before I take CILOSTAZOL?
See also Warning section. Before taking cilostazol, tell your doctor or pharmacist if you are allergic to it; 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: serious/active bleeding (such as bleeding ulcers, bleeding in the eye/brain), blood disorders (such as hemophilia, low platelet counts), heart disease (such as heart attack, chest pain, fast/irregular heartbeat), stroke, kidney disease. This drug may make you dizzy. Alcohol or marijuana (cannabis) can make you more dizzy. Do not drive, use machinery, or do anything that needs alertness until you can do it safely. Limit alcoholic beverages. Talk to your doctor if you are using marijuana (cannabis). 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. This medicine may cause stomach bleeding. Daily use of alcohol while using this medicine may increase your risk for stomach bleeding. Limit alcoholic beverages. Ask your doctor or pharmacist about how much alcohol you may safely drink. Cilostazol may cause a condition that affects the heart rhythm (QT prolongation). QT prolongation can rarely cause serious (rarely fatal) fast/irregular heartbeat and other symptoms (such as severe dizziness, fainting) that need medical attention right away. The risk of QT prolongation may be increased if you have certain medical conditions or are taking other drugs that may cause QT prolongation. Before using cilostazol, tell your doctor or pharmacist of all the drugs you take and if you have any of the following conditions: certain heart problems (heart failure, slow heartbeat, QT prolongation in the EKG), family history of certain heart problems (QT prolongation in the EKG, sudden cardiac death). Low levels of potassium or magnesium in the blood may also increase your risk of QT prolongation. This risk may increase if you use certain drugs (such as diuretics/"water pills") or if you have conditions such as severe sweating, diarrhea, or vomiting. Talk to your doctor about using cilostazol safely. Before having surgery, tell your doctor or dentist about all the products you use (including prescription drugs, nonprescription drugs, and herbal products). Older adults may be more sensitive to the side effects of this drug, especially swelling of the hands/feet (fluid retention) or QT prolongation (see above). During pregnancy, this medication should be used only when clearly needed. Discuss the risks and benefits with your doctor. It is unknown if this medication passes into breast milk. Consult your doctor before breastfeeding.
What may interact with CILOSTAZOL?
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: "blood thinners" (such as heparin, warfarin), certain other antiplatelet drugs (such as dipyridamole), tipranavir. This medication is sometimes used together with other drugs that may increase your risk of bleeding. Examples are certain antiplatelet drugs (such as aspirin, clopidogrel). Follow your doctor's instructions carefully and continue your medications as directed. Tell your doctor if you notice unusual bleeding. Consult your doctor or pharmacist for more details. Check all prescription and nonprescription medicine labels carefully since many medications contain pain relievers/fever reducers (aspirin, NSAIDs such as ibuprofen/naproxen) which can increase the risk of bleeding/antiplatelet effect when used with cilostazol. However, if your doctor has told you to take low-dose aspirin to prevent heart attack or stroke (usually 81-162 milligrams a day), you should keep taking the aspirin unless your doctor tells you not to. Ask your doctor or pharmacist for more details.
