MHRA warns Christmas foods may interact with medicines
The Medicines and Healthcare products Regulatory Agency (MHRA) has issued a reminder that some Christmas foods and drinks can interact with medicines, potentially altering how well they work or increasing the risk of side effects.
The agency highlighted the example of warfarin, where cranberry products – including juices and sauces – may increase the likelihood of bruising or bleeding.
Leafy greens and brassica vegetables – such as Brussels sprouts, broccoli and cabbage – are rich in vitamin K, which can reduce the effectiveness of warfarin when eaten in large or inconsistent amounts.
The MHRA advised that such foods do not need to be avoided, but intake should be kept consistent.
The agency also noted that sugary seasonal snacks can cause unexpected changes to blood glucose levels in people who use insulin. It advised enjoying these foods in moderation and following guidance from healthcare teams.
Tyramine-rich foods – such as aged cheeses, cured meats and dark chocolate – can cause problems for people taking monoamine oxidase (MAO) inhibitors, a type of antidepressant.
People taking these medicines should check the information provided with their prescription and follow the recommended food restrictions, the MHRA advised.
Dr Stephanie Millican from the MHRA’s safety and surveillance team said: ‘Many people don’t realise that what we eat and drink can affect how some medicines work.
‘With a little planning and the right advice, you can enjoy your festive favourites while keeping your treatment on track.’
The MHRA advised patients to read patient information leaflets and speak to a pharmacist or GP if unsure about possible interactions.
It also issued a reminder that any unexpected side effects or concerns about a medicine can be reported via the Yellow Card scheme.
