What Is Pletal Used For?
Pletal is mainly used for peripheral arterial disease (PAD), a condition where arteries supplying the legs become narrowed or blocked. In many people, PAD causes intermittent claudication—pain, cramping, or discomfort in the legs that appears when walking and improves with rest.
By improving blood flow and reducing clotting tendencies, cilostazol can help increase:
- Walking distance before symptoms start
- Walking tolerance and overall mobility
- Quality of life for people with claudication
Pletal is not a cure for underlying artery narrowing, but it can help manage symptoms alongside lifestyle measures and other cardiovascular risk management.
Mechanism of Action (How Pletal Works)
Cilostazol acts through multiple pathways to improve circulation. The main actions include:
-
Antiplatelet effect (helps reduce “stickiness” of platelets):
- It inhibits platelet aggregation, which can reduce the risk of small clots forming in narrowed vessels.
-
Vasodilation (supports relaxation of blood vessels):
- It helps blood vessels open more effectively, improving blood flow to the legs.
-
Improved microcirculation:
- It can improve blood flow at the smallest vessel level, which may translate into better walking ability.
-
Increased cyclic AMP signalling:
- Clinically, this contributes to both reduced platelet aggregation and vascular effects.
When Will You Notice Improvement?
Many people start to notice improvements in walking tolerance over time, though responses can vary. The timing below is a general guide:
- Early phase: some patients notice changes within 1–2 weeks.
- Ongoing benefit: clearer improvements are often seen over 4–12 weeks.
- If no benefit: it may be necessary for your healthcare professional to review whether cilostazol is appropriate and whether other causes of leg discomfort are present.
Keep taking Pletal as directed and combine it with an exercise and risk-management plan for best results.
Pharmacokinetics (How the Body Handles Pletal)
Pharmacokinetics describes how the body absorbs, distributes, metabolises, and eliminates a medicine. The following is a practical summary for patient understanding:
- Absorption: Cilostazol is absorbed after oral dosing and reaches active blood levels suitable for twice-daily use.
- Metabolism: It is metabolised mainly by liver enzymes. Two metabolites (including one often referenced as a major active metabolite) contribute to overall effect.
- Distribution: It circulates in the bloodstream and distributes into tissues, including where it can exert vascular and antiplatelet effects.
- Elimination: It is removed from the body through metabolic pathways and subsequent elimination, with a net effect of a dosing interval that supports symptom control.
If you have liver problems or take medicines that strongly affect liver enzymes, drug levels and safety can change. This is one reason regular medication review is important.
Typical Indications
Pletal is indicated for the symptomatic treatment of:
- Intermittent claudication in adults with peripheral arterial disease.
Cilostazol may be used in people where improvement in walking distance and symptoms is the main goal. It is generally considered alongside:
- Smoking cessation
- Supervised or structured exercise therapy
- Managing cardiovascular risk factors (e.g., cholesterol, blood pressure, diabetes)
- Appropriate antiplatelet and other cardiovascular medicines, as advised
How to Take Pletal (Dosing and Timing)
The usual dosing approach for cilostazol is twice daily, commonly in the morning and evening. Your individual dose may differ based on your medical history, other medicines, and how you tolerate treatment. Follow the specific instructions given to you.
General timing tips
- Pick a consistent schedule: take your morning dose at about the same time each day and your evening dose similarly.
- Try to keep doses 10–12 hours apart when possible.
- Swallow whole with water. Do not crush or chew unless your pharmacist advises otherwise.
- If a dose is missed: take it when you remember on the same day unless it is close to your next dose. Do not double doses.
With or without food?
Cilostazol can generally be taken with or without food. For consistency and to reduce stomach upset for some people, many prefer to take it with food (or after meals).
Food Interactions
Food may influence how quickly some medicines are absorbed. With cilostazol:
- General approach: consistent dosing relative to meals is helpful.
- High-fat meals: may affect absorption rate for some medicines; if you notice symptom changes depending on meals, discuss with a pharmacist.
- Grapefruit: grapefruit and certain other citrus products can affect liver enzymes involved in drug metabolism for some medicines. While the exact interaction profile for cilostazol can vary, it is wise to avoid large amounts of grapefruit and ask your pharmacist if you regularly use grapefruit products.
If you have a sensitive stomach, taking Pletal after a meal may be more comfortable.
Alcohol and Medicine Interactions
Alcohol can worsen side effects such as dizziness, headache, or stomach irritation in some people. It can also increase bleeding risk when combined with medicines that affect clotting.
Practical alcohol guidance
- Limit alcohol and observe how your body responds.
- Be cautious with heavy drinking because it can increase the risk of unwanted effects and affect liver metabolism.
- If you notice unusual bruising or bleeding after drinking, stop alcohol and seek medical advice.
Discuss your usual alcohol intake with a healthcare professional, especially if you also take other blood-thinning medicines.
Important Medicine Interactions
Interactions matter because cilostazol affects platelet function and is metabolised in the liver. Some medicines can increase cilostazol levels (raising side effects/bleeding risk), while others may reduce its effect.
Medicines that may increase bleeding risk
- Other antiplatelet medicines (e.g., aspirin or clopidogrel) and some anticoagulants may increase bleeding tendency.
- Non-steroidal anti-inflammatory drugs (NSAIDs) used regularly (e.g., ibuprofen, naproxen) may increase gastrointestinal bleeding risk in some people.
Medicines that may affect cilostazol metabolism
Cilostazol is metabolised by liver enzymes. Strong inhibitors can raise cilostazol concentration and increase risk. In particular, medicines that inhibit liver pathways (such as certain antifungals or some antibiotics) may require dose adjustment or avoidance.
Examples of interaction categories to discuss
- Strong enzyme inhibitors (some antifungals, certain antibiotics, and other medicines)
- Strong enzyme inducers (some seizure medicines and others)
- Other cardiovascular medicines (because of combined blood-pressure effects)
- Medicines for erectile dysfunction or other vasodilators (if relevant) due to possible additive vasodilation effects
Always provide your pharmacist or clinician with a complete list of medicines, including:
- Over-the-counter products
- Herbal supplements (e.g., ginkgo, garlic supplements, St John’s wort)
- Topical products that include active ingredients affecting circulation
Safety Profile and Side Effects
Like all medicines, cilostazol can cause side effects. Not everyone gets them, and many are mild. If symptoms are severe, persistent, or concerning, seek medical advice promptly.
Common side effects
- Headache
- Palpitations or a faster heartbeat sensation
- Dizziness
- Diarrhoea or stomach upset
- Flushing (warmth/redness)
- Swelling in some cases (e.g., fluid retention)
Less common but important adverse effects
- Bleeding problems (e.g., nosebleeds, bruising more easily, bleeding gums)
- Significant changes in heart rhythm or worsening chest discomfort
- Blood count abnormalities (rare; symptoms can include unusual fatigue, infections, or persistent bruising)
Seek urgent medical help if
- You have signs of serious bleeding (black/tarry stools, coughing/vomiting blood, sudden large bruises, blood in urine)
- You feel faint, have severe dizziness, or chest pain
- You experience significant shortness of breath or sudden swelling
- You develop an allergic reaction (swollen face/lips, rash with swelling, difficulty breathing)
Warnings and cautions
- Heart failure risk: Pletal is generally not used in people with certain types of heart failure. If you have any history of heart failure, discuss this carefully with your healthcare professional.
- Blood pressure and heart rate: cilostazol can cause palpitations or mild cardiovascular effects. Report a history of arrhythmias or ongoing heart symptoms.
- Bleeding risk: use caution if you take other medicines that affect clotting or if you have a history of bleeding problems.
- Liver impairment: metabolism involves the liver; liver disease may require extra caution or monitoring.
- Kidney impairment: dose adjustments or monitoring may be needed depending on severity.
Practical Use Tips (Getting the Best Results Safely)
Cilostazol works best when combined with lifestyle measures and regular risk-factor management. These tips may improve both symptom control and safety:
- Use an exercise routine: structured walking (often supervised) can improve claudication symptoms. Consider a plan that gradually increases walking distance, resting when pain starts, and continuing as tolerated.
- Track your symptoms: note when leg pain starts and how long it takes to improve with rest. This helps you (and your clinician) judge whether therapy is helping.
- Stay consistent with timing: twice-daily dosing works best when you keep a regular schedule.
- Watch for side effects: palpitations, headache, dizziness, diarrhoea, or unusual bleeding should be reported.
- Be careful with “as-needed” pain relief: if you use NSAIDs frequently, ask a pharmacist about bleeding and stomach risks.
- Review medicines at regular intervals: especially if you start new medications (including antibiotics or antifungals).
Alternative Options for Claudication (Discuss With a Clinician)
Treatment choices for PAD depend on your symptoms, cardiovascular risk profile, and overall health. Alternatives may include:
- Exercise therapy (first-line for symptoms): supervised or structured walking programs can improve functional capacity.
- Other symptom-relief medicines: depending on local practice and your medical profile, your clinician may consider different options. The suitability of each medicine depends on heart rhythm, blood pressure, bleeding risk, and other conditions.
- Cardiovascular risk reduction: cholesterol-lowering medicines, blood pressure control, diabetes management, and smoking cessation can improve overall outcomes.
- Antiplatelet therapy: sometimes used to lower cardiovascular events risk in PAD.
- Procedures for selected patients: if symptoms are severe or lifestyle measures are insufficient, your specialist may discuss angioplasty, stenting, or bypass surgery.
If you are considering stopping or switching from cilostazol, talk with a healthcare professional first—especially if you have significant PAD symptoms.

FAQ – Pletal (Cilostazol)
1) How does Pletal help with leg pain?
Pletal works by improving blood flow and reducing platelet clumping. This can increase the distance you can walk before claudication pain starts and may improve how quickly pain resolves with rest.
2) Is Pletal the same as a blood thinner?
Cilostazol has antiplatelet (anti-clotting) activity, which can affect bleeding risk. It is not the same as some anticoagulants (“blood thinners”), and the safety profile depends on your other medicines and health conditions. Discuss all medications with your pharmacist.
3) Can I take Pletal with aspirin or clopidogrel?
Sometimes these combinations are used under medical guidance, but they can increase bleeding risk. If you take antiplatelet medicines, ask your pharmacist to review the combination for safety.
4) What should I do if I miss a dose?
Take it when you remember unless it is close to the time for your next dose. Do not take two doses at the same time to make up for a missed tablet.
5) When should I expect benefits?
Some people notice changes within 1–2 weeks, but more noticeable improvements often occur over 4–12 weeks. If there is little or no benefit, discuss with your healthcare professional.
6) What side effects are most common?
Common side effects include headache, dizziness, palpitations, flushing, and diarrhoea. Many are mild, but if you experience severe or persistent symptoms, seek advice.
7) Who should not take Pletal?
Cilostazol may not be suitable for people with certain heart failure conditions and requires caution with liver problems, bleeding risk, and some drug combinations. Always review your medical history and current medicines with a pharmacist or clinician.
8) Can I drink alcohol while taking Pletal?
You may be able to drink alcohol in moderation, but alcohol can worsen dizziness or increase bleeding risk when combined with antiplatelet effects. Keep intake limited and seek advice if you notice unusual bruising or bleeding.
9) Are there interactions with antibiotics or antifungal medicines?
Yes. Some antibiotics and antifungals can increase cilostazol levels by affecting liver enzymes, which may raise side effect or bleeding risk. Tell your pharmacist if you are prescribed a new medicine.
10) Is Pletal safe for long-term use?
Many people use cilostazol long-term if it provides symptom benefit and is safe for them. Periodic review is important to assess whether it still helps, and to monitor for side effects and interactions as other medicines change.
