Treatment Strategies for Raynaud's Phenomenon

Non-Pharmacological Management (Essential Foundation for All Patients)

All patients with Raynaud's phenomenon must implement trigger avoidance and lifestyle modifications before or alongside any pharmacotherapy. 1

Cold Protection Measures

Wear insulated mittens (not gloves), warm footwear, hats, and coats when exposed to cold environments to reduce vasospastic attacks. 1
Use hand and foot warmers actively during cold exposure to further lower the frequency of digital ischemic episodes. 1
These cold protection strategies are consistently supported by strong evidence across major rheumatology guidelines. 1

Mandatory Lifestyle Modifications

Smoking cessation is absolutely mandatory because tobacco directly aggravates vasospasm and reduces treatment efficacy. 1, 2
Discontinue medications that precipitate vasospasm, including beta-blockers, ergot alkaloids, bleomycin, and clonidine, as these agents directly undermine all other therapies. 1, 2
Implement stress-reduction techniques to lessen emotionally triggered attacks. 1, 2
Avoid vibration injury and repetitive hand trauma, especially in occupational settings. 1, 2

Physical Therapy

Structured physical-therapy exercises aimed at stimulating peripheral blood flow and generating heat are beneficial for reducing episode frequency. 1, 2
In patients with connective-tissue disease and hand edema, approximately five weekly sessions of manual lymphatic drainage can improve hand function. 1

Pharmacological Treatment Algorithm

First-Line: Calcium Channel Blockers

Extended-release nifedipine is the recommended first-line agent for both primary and secondary Raynaud's phenomenon. 1, 3, 2

Start nifedipine extended-release 30 mg once daily on an empty stomach, then titrate over 7–14 days to a target of 60–90 mg daily according to therapeutic response and tolerability. 3
Nifedipine reduces attack frequency and severity in approximately two-thirds of patients with an acceptable safety profile and low cost. 1, 3
Meta-analyses of randomized controlled trials confirm that nifedipine reduces both frequency and severity of Raynaud's attacks. 3, 2
If nifedipine is not tolerated, alternative dihydropyridine calcium-channel blockers (e.g., felodipine, isradipine, diltiazem) may be used, although efficacy may be modestly lower. 1

Critical Safety Warnings:

Immediate-release nifedipine must not be used without concurrent beta-blocker therapy in patients with acute coronary syndromes, as omission is associated with increased mortality. 3
Nifedipine is contraindicated in patients with clinically significant left-ventricular dysfunction or high risk of cardiogenic shock. 3

Second-Line: Phosphodiesterase-5 Inhibitors

When calcium-channel blockers provide inadequate response, add or switch to a phosphodiesterase-5 inhibitor (sildenafil or tadalafil). 1, 3, 2

These agents effectively lower the frequency, duration, and severity of attacks. 1, 3
They are especially valuable when digital ulcers are present, as they promote ulcer healing and prevention. 1, 3, 2
Cost considerations and off-label status may limit their use. 1

Third-Line: Intravenous Prostacyclin Analogue (Iloprost)

For severe Raynaud's refractory to oral therapies, intravenous iloprost should be considered. 1, 3, 2

Iloprost has demonstrated efficacy in reducing attack frequency and severity. 1, 3
It is particularly effective for healing existing digital ulcers. 1, 3, 2

Management of Digital Ulcers

Prevention of New Digital Ulcers

Bosentan (endothelin-receptor antagonist) is the most effective agent for preventing new digital ulcers in patients with systemic sclerosis who have multiple baseline ulcers. 1, 3, 2

Initiate bosentan at 62.5 mg twice daily for 4 weeks, then increase to 125 mg twice daily. 3
Bosentan is particularly effective in patients with four or more digital ulcers at baseline. 3, 2
Phosphodiesterase-5 inhibitors also contribute to ulcer prevention, although study results are mixed. 1, 3

Healing of Existing Digital Ulcers

Intravenous iloprost and phosphodiesterase-5 inhibitors both have proven benefit in promoting healing of established digital ulcers. 1, 3, 2

Specialized wound-care teams should manage ulcer care, reserving antibiotics for suspected infection and providing adequate analgesia. 1, 3
Topical nitroglycerin may provide ancillary relief for acute painful episodes. 1, 3

Severity-Based Treatment Pathway

Mild Disease

Non-pharmacological measures alone are sufficient. 1
Add nifedipine if quality of life is impaired. 1

Moderate to Severe Disease or Inadequate Response to Calcium-Channel Blockers

Introduce or switch to a phosphodiesterase-5 inhibitor. 1, 3

Severe Refractory Disease

Consider intravenous iloprost. 1, 3

Presence of Digital Ulcers

Use bosentan for prevention and either intravenous iloprost or phosphodiesterase-5 inhibitors for healing. 1, 3, 2

Gangrene or Osteomyelitis

Amputation may be required in extreme cases. 1

Additional Treatment Options

Fluoxetine (a selective serotonin-reuptake inhibitor) can be considered in refractory cases, but supporting evidence is limited to small studies. 1, 3
Digital sympathectomy may be employed for persistent ulcer-related problems. 1, 3
Emerging therapies such as botulinum-toxin injections or autologous fat grafting show promise for ulcer healing and prevention. 1, 3

Critical Pitfalls to Avoid

Always screen for systemic sclerosis and other connective-tissue diseases, as Raynaud's is present in nearly all systemic-sclerosis patients and often represents the initial manifestation. 1, 3, 2

Red-Flag Features Requiring Urgent Assessment

Severe painful episodes with digital ulceration or tissue necrosis. 1, 3
Systemic symptoms (e.g., joint pain, skin changes, dysphagia, weight loss, fever). 1
Involvement of the entire hand rather than isolated digits. 1
Onset after age 60 (suggesting possible atherosclerotic disease). 1

Diagnostic Workup for Suspected Secondary Raynaud's

Order complete blood count with differential, erythrocyte sedimentation rate, antinuclear antibody panel, rheumatoid factor, anticentromere and anti-Scl-70 antibodies, anticardiolipin antibodies, and lupus anticoagulant testing. 1, 3

Common Treatment Errors

Continuing triggering medications (beta-blockers, vasoconstrictors) will undermine all treatment efforts. 2
Delaying escalation in secondary Raynaud's leads to digital ulcers and poor outcomes; more aggressive therapy is required. 2
Avoiding delays in rheumatology referral when red-flag features are present is the most significant preventable cause of poor outcomes. 3

Specialist Referral

Rheumatologists should be the primary specialists managing Raynaud's disease, especially when secondary causes or connective-tissue disease are suspected. 3

Early referral to rheumatology for patients with suspected secondary Raynaud's phenomenon is critical because delays are a major cause of postponed effective treatment. 3
Rheumatologists achieve superior outcomes: they diagnose earlier, prescribe disease-modifying therapies more frequently, and patients experience better prevention of complications. 3
