Cough Syrup – Best Choices for Adults, Kids & Chesty Cough
Choosing the right cough syrup in the UK can be confusing, especially with different rules for adults, children, and babies. Over-the-counter (OTC) cough medicines are widely available for chesty and dry coughs, but strict regulations prohibit most OTC cough syrups for children under 6 years and they are not recommended for babies under 1 year due to safety risks and lack of proven efficacy. This guide compares the best options by age group, symptom type, and retailer, drawing on official guidance and pharmacy expertise.
From codeine restrictions to price differences across Boots, Tesco, and Asda, understanding what to buy and what to avoid can save time and money. The UK market is dominated by brands like Covonia, Benylin, and Robitussin, alongside cheaper own-label alternatives. Below we break down the key considerations for every demographic.
Which Cough Syrup Is Best for Adults vs Kids?
Active ingredients: dextromethorphan (dry cough), guaifenesin (chesty cough). Brands: Covonia, Benylin, Robitussin. Available at supermarkets and pharmacies.
Products like Benylin Children’s and Calpol are common. Avoid codeine. For under-6s, UK government advises against OTC cough medicines.
No medicated syrups. Use saline drops or paracetamol/ibuprofen if needed after consulting a GP. Honey is unsafe due to botulism risk.
Expectorants like guaifenesin (Robitussin Chesty, Covonia Mucus Cough) help loosen mucus. Age suitability varies from 5+ years.
Key Insights

- Codeine-based syrups are banned for under-12s and available only on prescription in the UK since 2020.
- Boots, Tesco, and Asda offer own-brand chesty cough syrups that are significantly cheaper than branded alternatives.
- Covonia is the most commonly searched brand, with products for both chesty and dry coughs.

What Is Covonia Cough Syrup and How Does It Work?
Covonia is a well-known UK brand offering both chesty and dry cough formulations. The chesty cough mixture contains levomenthol, squill, and liquorice, which provide a mentholated soothing effect and help relieve phlegm. It is suitable for adults and children aged 5 years and older.
What Is Covonia Cough Syrup Used For?
Covonia products target specific symptoms: the chesty cough mixture is designed to loosen mucus and ease a sore throat, while the dry and tickly cough linctus relies on glycerol to coat the throat and suppress the cough reflex. Both are non-drowsy and available over the counter.
What Are the Side Effects of Covonia Cough Syrup?
Side effects are generally mild and may include gastrointestinal discomfort or allergic reactions in sensitive individuals. The product information advises against use in children under 5 years. As with any medicine, users should read the label and consult a pharmacist if symptoms persist.
Covonia is often cheaper than Benylin for similar-sized bottles. A 150ml bottle of Covonia Chesty Mixture typically costs around £3.50–£4.20 at Tesco or Asda, compared to £4.00–£5.50 for Benylin.
What Is the Best Cough Syrup for a Chesty Cough?
For chesty coughs where mucus is present, expectorants like guaifenesin are the first-line choice. The active ingredient helps thin and loosen phlegm, making it easier to cough up. Products such as Robitussin Chesty Cough and Covonia Mucus Cough are widely recommended.
Which Cough Syrup Is Best for Dry Cough vs Chesty Cough?
Dry coughs (no mucus) respond best to suppressants like dextromethorphan, which reduces the cough reflex. Examples include Covonia Dry & Tickly Cough Linctus and Robitussin Dry Cough Syrup. Chesty coughs require expectorants such as guaifenesin (Robitussin Chesty) or the mentholated mixture from Covonia.
Codeine-containing cough syrups are not available over the counter in the UK. They require a prescription due to opioid risks and are banned for under-12s. Always check the active ingredient before buying.
Is Codeine Cough Syrup Available in the UK?
Codeine linctus, once a common OTC cough remedy, is now restricted. Since 2020, the MHRA has made codeine cough syrups available only on prescription, and they must not be given to anyone under 18 years. This change followed concerns about addiction, misuse, and serious side effects in children.
What Is Codeine Linctus Cough Syrup?
Codeine linctus is an opioid-based cough suppressant used for severe, dry coughs. In the UK, it is no longer available over the counter. Patients who need it must obtain a prescription from a doctor, and pharmacists are advised to restrict supply.
Can I Buy Codeine Cough Syrup Over the Counter in the UK?
No. Codeine cough syrup is not available OTC. All codeine-based cough medicines are prescription-only. The MHRA advises that safer alternatives such as simple linctus or honey-based remedies should be used first.
Do not attempt to buy codeine cough syrup online from unregulated sources. Products sold without a prescription may be counterfeit or contain harmful ingredients. Always consult a GP for a legitimate prescription.
Where Can I Buy Cough Syrup at Major UK Retailers?
Most adult cough syrups are available on open shelves at supermarkets and pharmacies. For children aged 6–12, many products are classified as pharmacy (P) medicines, meaning they must be sold under pharmacist supervision. Below is a guide to availability at the main UK retailers.
| Store Type | What’s Available |
|---|---|
| Supermarkets (Tesco, Asda, Morrisons) | Adult chesty/dry syrups (GSL). Benylin/Covonia for 6+ years may be on open shelves, but some 6–12 year products are pharmacy-only. |
| Pharmacies (Boots, Lloyds) | All OTC syrups, including children’s versions (P status). Pharmacist advice provided. |
| Online (Amazon UK, Boots.com) | Full range, including 300ml sizes, often with next-day delivery. |
Price comparisons show that Covonia is generally cheaper than Benylin for similar sizes. Tesco and Asda often offer Clubcard or Parent Club discounts of 10–20% off. For example, a 150ml bottle of Covonia Chesty Mixture costs around £3.50–£3.90 at Tesco/Asda, while Benylin Children’s Chesty 125ml is £4.00–£4.80.
Key Dates in UK Cough Syrup Regulation
- 2020 – MHRA bans codeine linctus for under-12s and restricts to prescription only.
- 2022 – New labelling requirements for cough syrups to clearly state age restrictions.
- 2025 – Ongoing availability of OTC codeine-free alternatives; no further major regulatory changes.
What Is Known and What Remains Unclear About Cough Syrup Safety?
| Established Information | Information That Remains Unclear |
|---|---|
| Cough syrups for adults and children are widely available. Codeine is prescription-only. Babies under 1 should not have medicated cough syrup. | Effectiveness of natural remedies versus medicated syrups varies; no definitive clinical consensus for some herbal ingredients. Price fluctuation across retailers. |
How Does the UK Cough Syrup Market Work?
The UK cough syrup market is dominated by a few large brands (Covonia, Benylin, Robitussin) and pharmacy own-brands. Price sensitivity is high, with own-brand options offering similar active ingredients at lower cost. The codeine ban has reduced misuse but also limited options for severe cough. Parents frequently search for child-safe and baby-safe options, yet few resources provide a unified guide.
The NHS recommends simple linctus or honey for children over 1, and for adults to check active ingredients. Boots provides a cough medicine page but lacks cross-brand comparison. Pharmacists remain the best source of personalised advice.
What Do the Authorities Say?
“Cough medicines should not be given to children under 6 years old, and older children should use them carefully.”
NHS (via Boots website)
“Codeine-containing cough syrups are now only available on prescription in the UK, and should not be given to anyone under 18.”

What Should You Do Next?
When choosing a cough syrup, match the product to the cough type and age of the patient. For children, prefer non-medicated remedies like honey and lemon (over 1 year) or simple linctus. Compare prices across Boots, Tesco, Asda, and online retailers. For severe or persistent coughs, consult a pharmacist or GP.
