How to cope with Raynaud's symptoms
If your symptoms fail to improve, you may be prescribed nifedipine. This is the only medicine licensed to treat Raynaud's phenomenon in the UK. It doesn't cure Raynaud's, but can help to relieve the symptoms.
Nifedipine is a calcium channel blocker – a type of medication that encourages the blood vessels to widen.
Depending on the pattern of your symptoms and how well you respond to treatment, you may be asked to take your medication every day. Alternatively, you may only need to take it as prevention; for example, during a sudden snap of cold weather.
Side effects are common and include:
oedema – swelling of certain parts of the body, such as your hands and feet, due to a build-up of fluid
Don't drink grapefruit juice when taking nifedipine, as this could make side effects worse.
