Beware of inflammatory skin care, too many sprouts and too much cheese this Christmas, say health experts Health

Christmas may be a time of comfort and joy, but health experts warn of dangers ranging from the risk of fire from skin creams to possible interactions of festive foods with certain medications.

According to the Medicines and Healthcare products Regulatory Agency (MHRA), people who use medicated moisturizers, known as emollient creams, which are often used for eczema and other dry skin conditions, should stay away from heat sources such as candles and open flames, as such creams can penetrate fabrics and make them more flammable.

The agency also warns that traditional Christmas vegetables, including Brussels sprouts and broccoli, may be problematic for people taking the anticoagulant warfarin because their high levels of vitamin K can reduce the drug’s effectiveness.

“These foods should not be avoided entirely – instead, try to eat consistent amounts to ensure your vitamin K levels remain stable,” the MHRA said.

However, some people may have to forego festive treats. Aged cheese and dark chocolate are among the foods that contain a substance called tyramine. Tyramine may interact with drugs known as monoamine oxidase inhibitors (MAOIs), sometimes used to treat depression and Parkinson’s disease, causing a sudden increase in blood pressure.

Other foods that people taking these medications should avoid include staples of many Christmas tables such as smoked fish, beer, figs, gravy granules, pies and cheese biscuits, according to Torbay and South Devon NHS Trust.

Dr. Alison Cave, the MHRA’s chief safety officer, said: “The festive period is a time to come together, share traditions and create lasting memories. But as we fill our homes with light, warmth and cheer, it is important that we don’t forget safety – particularly around medicines and medical products.”

This also includes being careful with celebratory drinks. As the MHRA notes, some medicines taken with alcohol can cause drowsiness, dizziness or poor coordination.

“Even if you don’t drive, you should still exercise caution when using a mobility scooter or electric wheelchair,” the agency said. “These are medical devices and alcohol or medications that impair judgment may make them unsafe to use.”

The MHRA also says those looking to lose weight should be careful when purchasing weight loss medications online, noting that they should only be purchased with a prescription and from reputable websites.

“Products sold through unregulated websites or social media channels may be counterfeit, contaminated, incorrectly dosed, or contain potent ingredients not listed on the packaging,” the MHRA said. “Taking these medications can cause serious side effects, including heart problems, psychological effects, or dangerously low blood sugar.”

At a time of seasonal coughs and colds, the MHRA has also stressed the importance of sticking to dosage instructions and not taking multiple products with the same active ingredients such as paracetamol.

Prof Victoria Tzortziou-Brown, chair of the Royal College of GPs, welcomed the MHRA’s advice. She added that it was a good idea for patients to refresh their understanding of possible side effects of medications by looking at the patient information leaflet, checking the NHS website or speaking to a pharmacist. Health advice can also be obtained through NHS 111 services and GPs.

“The MHRA rightly highlights the risks associated with purchasing cheap ‘medical’ or cosmetic Christmas gifts online, particularly from unregulated sellers,” Tzortziou-Brown added. “If an offer seems too good to be true, it usually is.”
