Key Features

• Extra-Firm Medical Compression: Provides consistent high therapeutic pressure for managing severe venous and lymphatic insufficiency, delivering physician-prescribed gradient compression that actively combats advanced circulatory disorders.
• Maximum Strength Fabric Construction: Constructed with a durable 72% nylon, 28% spandex blend specifically engineered to deliver and sustain high compression levels through repeated wear and professional laundering protocols.
• Heavily Reinforced for Clinical Durability: Features heavy reinforcement in heel, toe, and sole areas to withstand the substantial rigors of daily donning and doffing at this intensive pressure level.
• Precise Graduated Pressure Profile: Maintains a strict medical-grade gradient, delivering the highest pressure at the ankle to forcefully combat venous pooling and severe edema accumulation.
• Wide, Non-Constricting Comfort Band: Features a broader top band specifically designed to distribute high pressure comfortably across a larger surface area, preventing rolling, cutting in, or tourniquet effects.
• Economical High-Compression Solution: Offers a cost-effective option for long-term, high-pressure compression therapy as part of a managed care plan for chronic conditions.
• Closed Toe Protection: Provides complete foot coverage for patients requiring full leg compression therapy without toe exposure concerns.
• Medical Device Classification: Meets stringent quality standards for Class 3 compression therapy devices used in clinical wound care and lymphedema management.

Therapeutic Benefits and Use

• Manages Severe Edema and Lymphedema: Applies strong, sustained pressure to reduce significant fluid accumulation, soften fibrotic tissue, and maintain limb volume reduction achieved through manual lymphatic drainage.
• Active Venous Ulcer Management: A cornerstone of evidence-based compression therapy for healing venous leg ulcers by improving microcirculation, reducing venous hypertension, and promoting wound closure.
• Prevention of Venous Ulcer Recurrence: Essential for maintaining ulcer closure and preventing reoccurrence after healing, with studies showing significantly reduced recurrence rates with consistent high compression use.
• Treatment of Post-Thrombotic Syndrome (PTS): Helps control pain, swelling, skin changes, and functional impairment associated with PTS following deep vein thrombosis (DVT) episodes.
• Management of Severe Chronic Venous Insufficiency (CVI): Addresses advanced manifestations including skin changes like hyperpigmentation, lipodermatosclerosis, venous eczema, and atrophie blanche.
• Supports Orthostatic Hypotension Management: The high compression can help mitigate symptomatic blood pressure drops upon standing for diagnosed patients with autonomic dysfunction.
• Reduces Venous Hypertension: Significantly decreases ambulatory venous pressure in the lower extremities, addressing the underlying pathophysiology of advanced venous disease.
• Improves Calf Muscle Pump Function: Enhances the efficiency of the muscle pump mechanism, improving venous return even in patients with compromised calf muscle function.

Important Medical Notice

Consult your physician before use. This high compression level is a medical device requiring professional evaluation. Do not use if you have: arterial disease (ABPI < 0.5), severe peripheral arterial disease, acute deep vein thrombosis, untreated cellulitis or dermatitis, congestive heart failure (unless under close monitoring), or a known allergy to garment materials. Proper medical diagnosis, professional fitting, and precise medical sizing are absolutely essential for safety and efficacy. Your vascular specialist or wound care physician can determine if this compression level is appropriate for your specific condition.

Frequently Asked Questions

Who prescribes 30-40 mmHg compression stockings?
This extra-firm compression is typically prescribed by a physician specializing in vascular medicine, wound care, or lymphedema management for specific severe conditions like active venous ulcers, severe lymphedema, or advanced post-thrombotic syndrome. Self-selection without medical guidance is not advised and may be contraindicated. See our compression therapy guide for comprehensive context on medical compression levels.

How do I put on such high compression stockings?
Donning aids are highly recommended and often essential at this compression level. Use donning gloves, a metal or plastic frame, or a specialized stocking slide to facilitate application while protecting the garment fibers. Ensure meticulous skin care, complete dryness, and consider applying in the morning when swelling is minimal. Accurate sizing via our compression stocking measuring guide is absolutely critical for both effectiveness and ability to don the garment.

Can I sleep in these compression stockings?
Generally, no. Extra-firm compression should be removed at night to allow tissues to rest and perfuse naturally, unless your doctor has given you specific instructions to wear them 24 hours a day (for example, during acute lymphedema treatment or intensive ulcer healing protocols). Always follow your physician's prescribed wearing schedule.

What if they feel too tight or cause pain?
Remove them immediately and consult your doctor. Do not continue wearing garments that cause numbness, tingling, severe pain, coldness, or color changes (white, blue, or dark purple) in your toes or feet. This may indicate incorrect size, improper application, compromised arterial circulation, or an underlying medical contraindication requiring immediate evaluation.

How long do 30-40 mmHg compression stockings last?
With proper care, medical-grade compression garments typically maintain therapeutic effectiveness for 3-6 months of daily wear. Monitor compression efficacy and garment condition regularly, and replace when you notice decreased compression, fabric thinning, or loss of elasticity. Your insurance may cover replacements on this schedule.

Do I need a prescription to purchase these?
While not always legally required for purchase, physician evaluation and prescription are strongly recommended for 30-40 mmHg compression. Many insurance plans require a prescription for reimbursement, and proper medical assessment ensures this high compression level is safe and appropriate for your specific condition.
