Hello, Thanks for your query. There is no cure for primary Raynaud s phenomenon, although the condition often can be effectively controlled. You may be able to limit or reduce the severity of attacks by keeping warm; managing emotional stress; and avoiding medicines or other substances that affect blood flow, such as nicotine, caffeine, or cold medicines that contain pseudoephedrine. Avoiding beta-blockers, which are often used to treat high blood pressure and fast or irregular heart rates, is also advised. I do hope that you have found something helpful and I will be glad to answer any further query. Take care
