Raynaud's Phenomenon

Raynaud's phenomenon is a condition where blood vessels in the fingers and toes (and sometimes in the earlobes, nose, and lips) constrict. It is usually triggered by cold or by emotional stress. Episodes are intermittent and may last minutes or hours. Approximately 5 to 10 percent of the U.S. population is affected, and women are affected five times more often than men. It usually occurs between the ages of 20 and 40 in women and later in life in men.

Signs and Symptoms

bulletChanges in skin color in the fingers or toes and sometimes in the nose, legs, or earlobes (may occur in three phases: white, blue, then red)
bulletThrobbing, tingling, numbness, and pain
bulletDeterioration of the pads on fingertips or toes
bulletGangrenous ulcers near fingertips


What Causes It?

Risk factors for Raynaud's phenomenon include the following.


bulletCigarette smoking
bulletAge in women (onset primarily between the ages of 20 and 40)
bulletOccupation (for example, using vibrating tools such as chain saws and jackhammers)
bulletDrug use, including some cancer drugs, narcotics, and over-the-counter cold medications
bulletElectric shock injury
bulletPrevious frostbite
bulletRepetitive physical stress (for example, typing or playing the piano)
bulletPrimary pulmonary hypertension
bulletExposure to cold
bulletPsychological stress
bulletGeneral medical conditions such as rheumatoid arthritis, scleroderma, systemic lupus erythematosus, and carpal tunnel syndrome


What to Expect at Your Provider's Office

Your health care provider may conduct several laboratory tests, such as the antinuclear antibody test, to look for antibodies associated with connective tissue disease or other autoimmune disorders. If you have Raynaud's phenomenon, your provider will most likely begin with a conservative approach involving non-drug and self-help measures (for example, dressing warmly, avoiding the cold, controlling stress).

Treatment Options

Treatment Plan

If you smoke, it is very important to stop because nicotine shrinks arteries and decreases blood flow. Protecting yourself well from the cold reduces episodes. Exercising can be good to increase circulation. Raising your arms above your head and vigorously whirling them can be a helpful exercise. Be careful not to cut or injure affected areas to avoid tissue damage. Several types of drugs and even surgery are used in more severe situations.

Drug Therapies



bulletCalcium channel blockers—are vasodilators (drugs that open up blood vessels) that reduce frequency and severity of episodes; various side effects including dizziness, headache, flushing, and heart palpitations
bulletAdrenergic blocking agents—increase blood flow to fingers and toes; various side effects
bulletNitroglycerine—relaxes smooth muscle and dilates veins


Over the Counter


Surgical Procedures

If attacks become extremely frequent and severe and interfere with your well-being and ability to work or function, a surgical procedure called sympathectomy may be used. This surgery becomes less effective as the disease advances.

Complementary and Alternative Therapies



bulletVitamin E (400 to 800 IU per day) improves circulation and helps certain blood cells function well.
bulletVitamin C (1,000 mg two to three times per day) supports connective tissue and reduces swelling.
bulletB-complex (50 to 100 mg per day) reduces stress.
bulletCoenzyme Q10 (100 mg two times per day) promotes healthy tissues.
bulletCalcium (1,500 mg per day) and Magnesium (200 mg 3 times per day) relieves spasm.
bulletOmega-3 oils (1,500 mg two to three times per day) reduce swelling and help certain blood cells function well.
bulletZinc (30 to 50 mg per day) boosts your immune system.



Herbs are generally a safe way to strengthen and tone the body's systems. As with any therapy, it is important to work with your provider on getting your problem diagnosed before you start any treatment. Herbs may be used as dried extracts (capsules, powders, teas), glycerites (glycerine extracts), or tinctures (alcohol extracts). Unless otherwise indicated, teas should be made with 1 tsp. herb per cup of hot water. Steep covered 5 to 10 minutes for leaf or flowers, and 10 to 20 minutes for roots. Drink 2 to 4 cups per day. Tinctures may be used singly or in combination as noted. The following herbs are circulatory stimulants with other properties as well. Use one or more tinctures in combination. Take 20 to 30 drops two times per day.


bulletHawthorn berries (Crataegus oxyanthoids) strengthens and mildly dilates blood vessels
bulletGinkgo (Ginkgo biloba) (120 to 160 mg per day for dried extracts) keeps blood cells from sticking together
bulletRosemary (Rosemariana officianalis) is a gentle relaxant
bulletGinger root (Zingiber officianale) is a mild soothing agent
bulletPrickly ash bark (Xanthoxylum clava-herculis) enhances lymph activity and integrity of blood vessels



Homeopathy may be useful as a supportive therapy.


Acupuncture may be useful as an adjunct therapy.

Following Up

Most milder cases can be brought under control through self-help measures.

Special Considerations

Many drugs used to treat Raynaud's phenomenon can affect a growing fetus and should not be used by pregnant women.
