What medications are used to treat varicose veins?

Medications for Varicose Veins

Medications play a limited role in treating varicose veins, with phlebotonics (venoactive drugs) being the primary pharmacologic option for symptom relief, though they do not cure the underlying venous reflux and should not delay definitive interventional treatment when indicated. 1

Phlebotonics (Venoactive Drugs)

Horse Chestnut Seed Extract (Aesculus hippocastanum)

• Horse chestnut seed extract may ease symptoms of varicose veins including pain, heaviness, and leg swelling, though long-term safety and effectiveness studies are lacking. 1
• The evidence supporting phlebotonics is rated as Level B, based on systematic reviews and Cochrane reviews of lower-quality randomized controlled trials. 1

Other Venoactive Agents

• Conservative therapies for symptom management include venoactive agents, though specific agents and dosing are not well-established in guidelines. 1
• Sulodexide has shown benefits in chronic venous insufficiency and venous leg ulcers, with recent data suggesting it could improve venous smooth muscle contraction. 2

Adjunctive Medications for Symptom Management

Nonsteroidal Anti-Inflammatory Drugs (NSAIDs)

• NSAIDs can be used for symptomatic relief of pain and discomfort associated with varicose veins. 1
• These medications address symptoms but do not treat the underlying venous reflux or prevent disease progression. 1

Hormonal Agents and Ergot Alkaloid Derivatives

• These agents are mentioned as conservative therapies for pelvic-origin lower extremity varicose veins, though specific evidence is limited. 1

Critical Treatment Algorithm Context

When Medications Are Appropriate

• Medications should be considered only for patients who are not candidates for endovenous or surgical management, do not desire intervention, or are pregnant. 3
• Conservative measures including medications are recommended when interventional treatment is ineffective or contraindicated. 3

When Medications Should NOT Delay Definitive Treatment

• For symptomatic varicose veins with documented valvular reflux in non-pregnant patients, referral for interventional treatment should not be delayed for a trial of medications or external compression. 1, 3
• This recommendation is rated as Level C evidence based on clinical guidelines and expert consensus. 1
• Endovenous thermal ablation has largely replaced surgery as standard of care due to better outcomes and fewer complications. 1, 3

Important Caveats

Insurance Requirements vs. Clinical Guidelines

• Insurance companies may require a trial of conservative management (including compression stockings) before approving interventional treatments, even though clinical guidelines do not support delaying definitive treatment. 3
• A documented 3-month trial of medical-grade gradient compression stockings (20-30 mmHg) may be required for insurance authorization. 3, 4

Evidence Limitations

• There is insufficient high-certainty evidence that compression stockings or medications are effective as sole treatment for varicose veins without venous ulceration. 5, 6
• The certainty of evidence for conservative treatments is low to very low due to small studies, inadequate reporting, and heterogeneity. 5

Medications Do Not Address Underlying Pathophysiology

• Varicose veins result from valvular reflux and venous hypertension, which medications cannot correct. 1, 7
• Without treating the underlying reflux, symptoms typically recur and disease may progress to chronic venous insufficiency with skin changes or ulceration. 8, 7, 2
