Poor blood circulation in the legs, often a symptom of underlying conditions like Peripheral Artery Disease (PAD) or Chronic Venous Insufficiency (CVI), can cause pain, cramping, and fatigue. While diagnosis and treatment must always be guided by a healthcare provider, several types of tablets are commonly prescribed to manage symptoms and improve blood flow. These medications address the issue by widening blood vessels, preventing blood clots, or treating underlying causes like high cholesterol.

Prescription Tablets for Peripheral Artery Disease (PAD)
Peripheral Artery Disease (PAD) is a condition in which narrowed arteries in the legs restrict blood flow, a process called atherosclerosis. The resulting leg pain during exercise is known as intermittent claudication. For PAD, doctors commonly prescribe specific tablets to improve circulation.
Cilostazol
Cilostazol (brand name Pletal) is a primary treatment for intermittent claudication. It works in two ways to improve blood flow to the legs:
- Vasodilation: It relaxes and widens the blood vessels, allowing more blood to flow through.
- Antiplatelet effects: It keeps blood platelets from sticking together, which helps prevent blood clots from forming.
By improving blood flow, Cilostazol helps patients with PAD walk longer distances with less pain. It is important to note that Cilostazol is contraindicated for patients with heart failure. Side effects may include headache, diarrhea, dizziness, and heart palpitations. It can take several weeks or even months to see the full benefit.
Pentoxifylline
Pentoxifylline (brand name Trental) is another tablet used to treat intermittent claudication. It is known as a hemorrheologic agent, meaning it affects the thickness and flow of blood. Pentoxifylline works by:
- Making blood less viscous (thick), helping it flow more easily, especially in smaller vessels.
- Increasing the flexibility of red blood cells, which allows them to pass through narrow arteries more effectively.
- Providing anti-inflammatory and antioxidant benefits.
This medication can also help patients walk longer distances without leg pain. Common side effects include nausea, vomiting, dizziness, and headaches. Pentoxifylline is typically taken with food to minimize stomach upset.
Associated Medications for Managing Poor Circulation
In addition to specific circulation enhancers, other prescription medications treat underlying conditions that contribute to poor blood flow.
Statins
Statins are cholesterol-lowering tablets used to treat atherosclerosis, the buildup of plaque that narrows arteries in PAD. Common examples include atorvastatin (Lipitor) and simvastatin (Zocor). By lowering LDL ('bad') cholesterol, statins slow the progression of plaque buildup, which protects against heart attack, stroke, and limb loss.
Antiplatelets
Medications like aspirin or clopidogrel (Plavix) prevent blood platelets from sticking together. For patients with PAD, these are often prescribed to reduce the risk of blood clots, heart attack, and stroke. This is different from the specific vasodilator effect of Cilostazol, though both target platelets.
Anticoagulants
Often called "blood thinners," anticoagulants such as warfarin, rivaroxaban (Xarelto), and apixaban prevent or dissolve blood clots. They are crucial for treating and preventing deep vein thrombosis (DVT), a serious type of blood clot in the leg veins.
ACE Inhibitors and Angiotensin II Receptor Blockers (ARBs)
These medications are used to lower high blood pressure, a significant risk factor for vascular disease. By relaxing and widening blood vessels, they allow blood to flow more easily. Examples include lisinopril and losartan.
Over-the-Counter Supplements and Herbal Remedies
Many supplements are marketed for improving circulation, but it is critical to approach these with caution. The FDA does not regulate supplements in the same way as prescription drugs, and their effectiveness is often not clinically proven for treating serious vascular conditions. Always consult a doctor before taking any supplement, as they can interact with other medications.
Commonly Mentioned Supplements
- Diosmin and Hesperidin: These bioflavonoids are sometimes used for chronic venous insufficiency (CVI) and varicose veins. Studies have shown they can help reduce inflammation and improve venous tone.
- Horse Chestnut Extract: Often included in vein health supplements, horse chestnut is thought to reduce inflammation and swelling associated with CVI.
- L-Arginine: This amino acid can increase nitric oxide production, a natural vasodilator that helps relax blood vessels.
- Vitamins: Vitamins C, E, and B-complex are sometimes promoted for vascular health, but they are not a substitute for prescribed medication. For instance, Vitamin E may have anti-clotting properties, and Vitamin C supports vein walls.
Non-Pharmacological Treatments for Improving Blood Flow
Medication is often most effective when combined with lifestyle changes. Adopting healthy habits can significantly improve circulation and support overall vascular health.
Lifestyle Modifications
- Regular Exercise: Activities like walking, cycling, and swimming strengthen calf muscles, which help pump blood back to the heart. Structured exercise programs are especially beneficial for PAD.
- Quit Smoking: Smoking is one of the most damaging habits for the circulatory system, as it severely narrows arteries and increases blood clot risk. Quitting is one of the single most effective measures to improve circulation.
- Healthy Diet: A diet rich in fruits, vegetables, whole grains, and healthy fats can help control weight, cholesterol, and blood pressure. Foods high in antioxidants and omega-3 fatty acids are particularly beneficial.
- Weight Management: Carrying excess weight puts additional strain on the heart and veins, hindering proper circulation.
- Hydration: Staying well-hydrated helps maintain optimal blood volume and flow.
Supportive Therapies
- Elevate Legs: Propping up your legs above heart level for 15–20 minutes daily helps reduce swelling and encourages blood flow back to the heart.
- Compression Stockings: These specialized garments apply pressure to the legs, improving circulation and reducing swelling, particularly in CVI.

Conclusion
Several types of tablets, including prescription medications like Cilostazol and Pentoxifylline, can be used to improve blood circulation in the legs, primarily by addressing the underlying causes of Peripheral Artery Disease. Other drugs, such as statins and blood thinners, also play vital roles in managing risk factors and preventing complications. While numerous supplements are available, their effectiveness is often not scientifically proven for serious vascular conditions, and they should never replace a doctor-prescribed treatment plan. The best approach involves a combination of medication, lifestyle changes, and supervision by a healthcare professional to ensure safe and effective treatment.
