The following lifestyle changes may help people with Raynaud's phenomenon:
- Stop smoking
- Avoid caffeine
- Stop and avoid medications that cause tightening or spasms of the blood vessels
- Avoid exposure to cold in any form. Wear mittens or gloves outdoors and when handling ice or frozen food. Avoid getting chilled, which may happen after any active recreational sport.
- Wear comfortable, roomy shoes and wool socks. When outside, always wear shoes.
Your health care provider may prescribe medications to relax the walls of the blood vessels. These include topical nitroglycerin, calcium channel blockers, sildenafil (Viagra), and ace inhibitors.
It is important to treat the condition causing Raynaud's phenomenon.
