Raynaud’s disease is treated with a combination of lifestyle changes and, when needed, medications that relax blood vessels and improve circulation to your fingers and toes. Mild cases often improve with behavioral strategies alone, while more severe or secondary forms typically require prescription therapy. The right approach depends on whether your Raynaud’s is primary (occurring on its own) or secondary (linked to another condition like an autoimmune disease).
Why the Type of Raynaud’s Matters
Primary Raynaud’s is the more common form. It shows up on its own, usually in your teens or twenties, and tends to be uncomfortable but not dangerous. Secondary Raynaud’s is driven by an underlying condition, most often scleroderma, lupus, or another connective tissue disease. It carries a higher risk of complications like digital ulcers and tissue damage, and almost always requires medication.
If your Raynaud’s developed after age 30, affects one hand more than the other, or comes with skin changes, joint pain, or sores on your fingertips, it’s more likely secondary. Treatment for secondary Raynaud’s also means managing whatever condition is behind it.
Lifestyle Changes That Actually Help
Lifestyle modifications are the foundation of treatment for every Raynaud’s patient, and for mild primary cases, they may be all you need. The core principle is keeping your whole body warm, not just your hands. When your core temperature drops, your body redirects blood away from your extremities, and that’s what triggers an attack.
Temperature has a surprisingly direct relationship with symptom severity. Research on scleroderma patients found that Raynaud’s severity scores drop meaningfully as outdoor temperatures rise from 5°C to 25°C (41°F to 77°F), with the biggest improvements happening in that range. Interestingly, symptoms also worsen again above 25°C (77°F), likely because air conditioning creates sudden temperature swings. The practical takeaway: it’s not just winter you need to plan for. Grocery store freezer aisles, over-cooled offices, and reaching into the freezer at home are all common triggers.
Specific strategies that work:
- Layer your core. A warm torso signals to your body that it’s safe to keep blood flowing to your fingers and toes. Insulated vests and base layers matter more than gloves alone.
- Use chemical hand warmers strategically. Disposable iron-powder warmers generate heat up to 44°C (111°F) and last about six hours. A clinical trial found that placing warmers on the upper arms near the elbows helped relieve symptoms in scleroderma patients without covering the fingers, so patients could still use their hands normally for daily tasks.
- Warm your hands before they go numb. Once an attack starts, it’s harder to reverse. If you feel the early tingling, run warm (not hot) water over your hands or tuck them under your arms.
- Quit smoking. Nicotine constricts blood vessels and directly worsens Raynaud’s.
- Limit caffeine and certain medications. Stimulants, some migraine drugs, and decongestants containing pseudoephedrine can narrow blood vessels.
First-Line Medications
When lifestyle changes aren’t enough, calcium channel blockers are the standard first medication. These drugs relax the smooth muscle in blood vessel walls, keeping small arteries in your fingers and toes open wider. Nifedipine is the most commonly prescribed option for Raynaud’s. Your doctor will typically start at a low dose and adjust based on how you respond.
Calcium channel blockers can cause side effects like headaches, flushing, dizziness, and ankle swelling. These tend to be mild and often improve after the first few weeks. The extended-release versions cause fewer side effects than short-acting formulations.
Topical nitroglycerin ointment (usually a 2% concentration) is another first-line option. You apply it directly to your fingers, where it releases nitric oxide and dilates blood vessels locally. The advantage is that it targets the problem area without as much systemic effect. The disadvantage is headaches, which can be significant. Because the drug absorbs through the skin and dilates blood vessels elsewhere in the body, headaches are the most commonly reported side effect.
When First-Line Treatments Fall Short
If calcium channel blockers and topical treatments don’t control your symptoms, a class of drugs originally developed for erectile dysfunction offers a meaningful second option. These medications work by blocking an enzyme that breaks down a natural vessel-relaxing signal in your body, keeping blood vessels open longer.
A study published in Circulation tested this approach in patients whose Raynaud’s had resisted standard vasodilator therapy. Over four weeks, treated patients experienced about 33% fewer attacks compared to placebo (35 attacks versus 52), and total attack duration dropped by nearly half (581 minutes versus 1,046 minutes). Perhaps most strikingly, capillary blood flow velocity more than quadrupled. Among the six patients with chronic digital ulcers, all showed visible healing, and two had their ulcers disappear completely.
Endothelin receptor antagonists are another option for severe secondary Raynaud’s, particularly when digital ulcers are present. These block a potent vessel-constricting protein and are typically reserved for patients with scleroderma-related Raynaud’s who haven’t responded to other treatments.
Botulinum Toxin Injections
Botulinum toxin injections into the hand have emerged as a treatment for Raynaud’s that doesn’t respond to medications. The injections are placed near the blood vessels at the base of the fingers, where they block the nerve signals that trigger vessel constriction. In a retrospective study of 46 patients, about 72% reported overall improvement one month after injection.
The effects are temporary, typically lasting several months before repeat treatment is needed. This approach is most often used for secondary Raynaud’s with severe symptoms or early signs of tissue damage, not as a routine treatment for mild cases.
Surgical Options for Severe Cases
Digital sympathectomy is a procedure reserved for patients with critical blood flow problems who haven’t responded to other treatments. A surgeon strips away the tiny nerves wrapped around the finger arteries that cause them to constrict. This can restore blood flow and is sometimes performed urgently when tissue is at risk.
Critical digital ischemia, where blood flow to a finger is severely and persistently reduced, is treated as a medical emergency. Signs include persistent pain that doesn’t resolve when you warm up, open sores on your fingertips that heal slowly or not at all, and skin that turns dark or black at the tips. These symptoms mean tissue is being damaged and need immediate medical attention.
Managing Attacks in Real Time
Even with treatment, you’ll likely still experience some attacks. Knowing how to shorten them matters. When you feel an attack starting, move to a warmer environment if possible. Swing your arms in wide circles to push blood toward your fingertips through centrifugal force. Run warm water (around 100-104°F) over the affected area. Avoid rubbing your fingers directly, as numb skin is more vulnerable to injury than you might realize.
Stress is a major and often underestimated trigger. The same fight-or-flight response that cold activates can be triggered by emotional stress, redirecting blood away from your extremities. Techniques that lower your stress response, whether that’s deep breathing, exercise, or biofeedback, can reduce attack frequency for some people. If your attacks seem to correlate more with anxiety or pressure than with temperature, this is worth paying attention to.
