From the Guidelines
The most effective treatment for Raynaud's phenomenon when toes go numb is to keep extremities warm and use calcium channel blockers like nifedipine (10-20 mg three times daily) as first-line treatment. To manage Raynaud's phenomenon, it is essential to avoid triggers such as cold temperatures, stress, and smoking 1. Wearing proper clothing, including warm socks, insulated footwear, and using hand/foot warmers, can help prevent attacks 1. When an attack occurs, warming the feet gradually by soaking them in warm water or moving to a warmer environment can help alleviate symptoms.
For medication options, calcium channel blockers like nifedipine are the first-line treatment, as they help dilate blood vessels and improve blood flow to the extremities 1. Other medications, such as topical nitroglycerin, sildenafil, or losartan, may also be considered, but their use should be guided by a healthcare provider 1. In severe cases, more specialized treatments like intravenous prostacyclins may be necessary 1. It is crucial to consult a healthcare provider if symptoms worsen, develop ulcers, or do not respond to treatment, as this could indicate a more serious underlying condition 1.
Some key points to consider in the management of Raynaud's phenomenon include:
- Avoiding triggers and keeping extremities warm
- Using calcium channel blockers as first-line treatment
- Considering other medications, such as topical nitroglycerin or sildenafil, under the guidance of a healthcare provider
- Seeking medical attention if symptoms worsen or do not respond to treatment.

Treatment Options for Raynaud's Phenomenon
When toes go numb due to Raynaud's phenomenon, treatment options are available to manage the condition. The following are some of the treatment approaches:
- Non-pharmacological treatment, including avoiding cold and smoking cessation 2
- Calcium channel antagonists, such as nifedipine, which can reduce the frequency and severity of vasospastic attacks 3, 2, 4
- Other pharmacological treatments, including:
Individualized Treatment Approach
It is essential to note that the treatment of Raynaud's phenomenon should be individualized, especially when the condition is severe and accompanied by digital ulcers or tissue necrosis 3. The therapeutic regime may involve combinations of different drugs, and the response to treatment can vary and is difficult to predict 5, 6.
