As the UK braces for a cold snap with anticipated snowfall, it’s time to prepare not just your wardrobe but also your medicine cabinet. A leading pharmacist has outlined five key medications that households should consider stocking up on to combat the seasonal drop in temperature.

Peter Thnoia, who serves as the superintendent pharmacist for PillTime, an online pharmacy, emphasizes the importance of being proactive with treatments for common winter ailments like coughs and colds.

To help fend off winter woes, Thnoia has compiled a list of five essential medications everyone should have ready at home. Here’s a look at his top picks.

1. Vitamin D3 (not D2)

Among his recommendations, Vitamin D supplements stand out as crucial for adults in the UK, particularly throughout autumn and winter. With diminished sunlight exposure during these months, Vitamin D plays a vital role in bolstering the immune system, maintaining bone health, and enhancing overall wellness.

“Vitamin D is one of those unnoticed heroes,” Thnoia remarked. “While you might not realize its presence when levels are sufficient, a deficiency is certainly felt. For this reason, we advise everyone in the UK to take a daily supplement from October through March. It provides essential support for your immune system, bone integrity, and general health when your body requires a bit more assistance.”

“That’s why we recommend everyone in the UK takes a daily supplement between October and March. It supports immunity, bone health, and general wellbeing during the months when our bodies need a little extra help.”

Vitamin D3 is generally more effective and better absorbed by the body than D2, Mr Thnoia added.

He said: “For most adults, the NHS recommends 10 micrograms a day, and it’s advised not to exceed 100 micrograms (4,000 IU). Children and infants have even lower safe limits.

“If you’re unsure about how much to take, especially if you have an existing health condition, it’s always best to check with your doctor or pharmacist.”

2. Paracetamol

Most of us reach for paracetamol to treat common ailments and it can be helpful when dealing with the early signs of a cold. But Mr Thnoia warned not to double-dose when using cold and flu medicines in combination.

He explained: “It’s brilliant for bringing down fevers and helping with headaches or general winter aches, which are all those typical signs when something’s brewing.

“But it’s important to remember that a lot of cold and flu tablets already contain paracetamol, so you need to be careful not to double up. Always check the label and stick to the stated dose.”

3. Sore throat remedies

Lozenges or throat sprays can help ease pain and irritation, one of the earliest cold symptoms.

Mr Thnoia said: “Winter viruses often start with a sore, dry throat, and it can really knock you off your stride. Lozenges with a mild anaesthetic can ease the sting, and sprays are great for targeting pain more directly.”

4. Saline nasal spray

Saline nasal sprays can help to relieve congestion, particularly for people who are prone to sinus issues.

Mr Thnoia said: “It’s always worth having a few of these ready to go, especially if you talk a lot in your job or work in a colder environment.”

5. Cough syrups

Coughs and colds can spread more easily when people spend more time indoors during the colder months. Choosing the right cough syrup to match your symptoms — whether it is a tickly or chesty cough — can help speed recovery, Mr Thnoia said.

He added: “We always see a rise in coughs and sniffles as the weather turns, it’s part of the season.

“But what makes a big difference is being stocked up ahead of time, especially if you rely on regular medication too. No one wants to be caught out during a weekend.”
