Cough syrup is one of the most commonly purchased over‑the‑counter remedies in the UK, but finding the right product depends on the type of cough, the age of the person, and where you shop. Adults with a chesty cough are often directed toward guaifenesin products such as Benylin Chesty Cough or Covonia Chesty Cough, while a dry tickly cough typically leads to dextromethorphan‑based syrups like Benylin Dry Cough. For children under six and for babies, the NHS advises against routine use of over‑the‑counter cough medicines, recommending simple home remedies instead.
The UK market includes established brands such as Benylin, Covonia, Boots, and Superdrug, each offering a range of syrups for different symptoms. Retailers like Tesco, Asda, and Boots stock these products, and own‑brand alternatives are also widely available. Codeine‑based cough syrups are no longer sold over the counter and are restricted to prescription‑only use.
This guide covers the best cough syrup choices for adults, children, and babies, explains where to buy them, discusses popular brands, and outlines the regulatory position on codeine linctus in the UK. All information is based on official NHS guidance, pharmacist reviews, and retailer listings.
What Cough Syrup is Recommended for Adults, Kids, and Babies?
Cough syrups like Boots 5‑in‑1, Benylin Chesty Coughs, and Covonia Chesty Cough are commonly recommended for adults. Always check age restrictions – many are not for under 12.
For children under 12, NHS recommends honey and lemon (for ages 1+). Avoid cough syrups with codeine. Products like Calpol and simple linctus are safer options.
Leading brands include Benylin, Covonia, Boots Pharmaceuticals, and Superdrug own brand. Each offers different active ingredients for dry or chesty coughs.
Cough syrups are widely available at Boots, Tesco, Asda, Superdrug, and online. Prices vary; check own‑brand options for cost savings.
- Cough syrups for adults often contain guaifenesin (expectorant) or dextromethorphan (suppressant), while children under 12 should avoid many of these.
- The NHS advises hot lemon and honey as a first‑line remedy for coughs, especially for children, as cough syrups may not be effective.
- Codeine‑based cough syrups (codeine linctus) are restricted in the UK – available only on prescription and not recommended for children under 18.
- Retailer own‑brand cough syrups (e.g., Tesco, Boots, Asda) offer affordable alternatives to branded products with similar active ingredients.
- For chesty coughs, expectorants like guaifenesin help loosen mucus; for dry coughs, suppressants like dextromethorphan reduce the cough reflex.

Where to Buy Cough Syrup in the UK: Tesco, Asda, and Boots
Cough syrups are available at major UK pharmacies and supermarkets. Boots has a dedicated cough‑medicine category with multiple treatments, including own‑brand options. Tesco stocks brands such as Covonia and its own Tesco Health Chesty Cough Relief Oral Solution. Superdrug also carries a range of cough medicines. Prices vary, and comparison sites such as Trolley.co.uk list popular cough syrups and where they are sold.
When buying cough syrup at Tesco, Boots, or Asda, check the active ingredient on the label. For chesty coughs look for guaifenesin; for dry coughs look for dextromethorphan. Own‑brand syrups often contain the same ingredients as branded versions at a lower price.
At Boots, the 5‑in‑1 Multi‑Symptom Action Cough Syrup is a frequently chosen product for adults. Tesco listings include Covonia Chesty Cough Relief Liquid and Tesco Health Chesty Cough Relief. Asda and Superdrug provide similar selections. The availability of specific products can change, so checking the retailer’s website before visiting is advisable. For more on where to find these products, see our UK cough syrup buying guide.
Is Covonia an Effective Cough Syrup?
Covonia is a well‑known UK brand offering several cough syrups. Covonia Chesty Cough Sugar Free Syrup contains guaifenesin and is described as a more strongly mentholated choice. Covonia Dry and Tickly Cough Linctus is a honey‑based formula suitable for adults and children over one year. The brand is widely stocked at Tesco and other retailers. Pharmacist guides often list Covonia alongside Benylin as a top option.
Covonia’s effectiveness depends on matching the product to the cough type. For a chesty cough, the guaifenesin formulation helps thin mucus. For a dry tickly cough, the honey‑based linctus provides soothing relief. As with all cough medicines, individual results vary.
What is the Best Cough Syrup in the UK?
There is no single best cough syrup for everyone. The most suitable product depends on the cough type, age, and individual health factors. For chesty coughs in adults, Benylin Chesty Cough and Covonia Chesty Cough are commonly recommended. For dry coughs, Benylin Dry Cough (containing dextromethorphan) is a frequent choice. Bronchostop is sometimes listed as a broad option for both dry and chesty symptoms.
The NHS advises that many coughs resolve on their own and that simple home remedies such as hot lemon and honey are effective for symptom relief. For children under six, over‑the‑counter cough syrups are not routinely recommended. Parents should consult a pharmacist or GP for age‑appropriate advice. For a deeper look at the best options by symptom, read our guide to cough syrups for adults.
No single product is proven to be the “best” for all cough types. Clinical effectiveness varies, and most cough syrups primarily relieve symptoms rather than shorten the duration of the cough. Always read the label and follow age restrictions.
Can You Buy Codeine Cough Syrup in the UK?
Codeine linctus, a cough syrup containing the opioid codeine, is not available over the counter in the UK. In 2018, it was reclassified as a prescription‑only medicine due to risks of addiction and misuse. It is generally reserved for severe, persistent dry coughs and is not recommended for children under 18.
The MHRA guidance states that codeine linctus should only be used under medical supervision. Over‑the‑counter sales are illegal, and it is not stocked on the shelves of supermarkets or pharmacies. Anyone seeking codeine cough syrup must obtain a prescription from a doctor.
Codeine cough syrup is not safe for children and can cause respiratory depression. In the UK, it is restricted to prescription‑only use for adults under strict medical guidance. Do not attempt to buy codeine linctus without a prescription.
Key Regulatory Timeline for Cough Syrups in the UK
- 2018 – Codeine linctus reclassified as a prescription‑only medicine due to risk of addiction and misuse.
- 2020 – NHS updates guidelines for children’s cough medicines, recommending against over‑the‑counter cough syrups for children under 6.

Background: How Cough Syrups Fit into UK Self‑Care
Cough syrup is a common over‑the‑counter remedy, but the UK market is segmented by age, symptom type, and regulatory restrictions. Adults have a wide choice of expectorants and suppressants, while children under 12 require careful product selection – often avoiding most commercial syrups. Retailers like Boots, Tesco, and Asda offer convenient access, but price and brand vary. Codeine‑based syrups are tightly controlled. The NHS position is that many coughs resolve on their own and symptom relief can be achieved with simple home remedies. This guide helps users navigate the options based on age, location, and preference.
