Dry Cough or Chesty Cough? How to Pick the Right Medicine.
Stand in front of the cough medicine shelf for long enough and the labels can quickly start to blur together: dry, chesty, suppressant, expectorant, non-drowsy. You don’t need to work through every box to find the right option. Here are a few questions we’d usually ask at the pharmacy counter to help you understand which type of cough medicine may be most suitable for you.
3 Key Things to Know
Dry and chesty coughs are different and may need different approaches
Choosing the right type of medicine depends on your symptoms
Not every cough needs the same treatment, and some symptoms may need further advice
Educational Guide
What kind of cough have you actually got?
A dry or “tickly” cough does not usually produce mucus. It may feel like a tickle or irritation in the throat and can sometimes be worse when talking, lying down, or in cold or smoky environments.
A chesty or “productive” cough produces mucus and may sound or feel rattly. You may also feel the need to clear your throat or cough up phlegm.
A cough can sometimes change from dry to chesty, or vice versa, as an illness develops. This means the type of treatment that is most suitable for your symptoms may change too.
Why the medicine has to match the cough?
This is where choosing the right type of cough medicine matters:
Cough suppressants, such as those containing dextromethorphan, work by reducing the urge to cough. They may be more suitable for a dry, irritating cough where there is no mucus to clear.
Expectorants, such as those containing guaifenesin, help loosen and thin mucus, making it easier to cough up with a chesty cough.
Using a cough suppressant when you have a chesty cough may not be appropriate because coughing helps clear mucus from the airways. If you are unsure which type of cough you have, speak to a pharmacist before choosing a treatment.
Expert Advice
A suppressant on a chesty cough can trap the very mucus it should be helping you clear. Match the medicine to the cough, not just to whichever bottle is at eye level.
Choosing a Cough Medicine Based on Your Symptoms
Dry, tickly cough: a cough syrup containing glycerol or dextromethorphan may help soothe the irritation and reduce the urge to cough, particularly at night.
Chesty cough with mucus: an expectorant containing guaifenesin may help loosen the mucus on your chest, making it easier to cough up.
Cough that’s worse at night: a cough suppressant may help reduce coughing before bed. Honey and warm lemon can also be soothing.
Looking for a sugar-free option: sugar-free cough medicines and lozenges are available. If you have diabetes or need to avoid sugar, ask a pharmacist which option is most suitable for you.
Educational Guide
When your cough needs more than an over the counter treatment
Speak to a pharmacist, GP or other healthcare professional if your cough:
Lasts for more than three weeks
Causes you to cough up blood, or phlegm that is rust-coloured or unusually dark
Comes with chest pain, shortness of breath or a high temperature
Causes wheezing that does not settle between coughing episodes
Started soon after you began taking a new medicine, as some medicines can cause a persistent dry cough
If you’re unsure what to do or need medical advice, contact NHS 111 by calling 111.
If you have severe difficulty breathing, severe chest pain or feel seriously unwell, call 999 or go to A&E.
Your Consultation: 4 Common Questions
1. Can I take a suppressant and an expectorant together?
Not usually, they work in opposite directions, so combining them tends to cancel out the benefit of both. If your cough is doing both (dry at night, chesty in the day), message us and we'll suggest a sensible routine
2. Is honey and lemon actually useful?
It can help soothe an irritated throat and may make a cough feel more comfortable, particularly at night. It can be used as a simple comfort measure alongside other treatments. Honey should not be given to babies under 1 year old.
3. Why can a cough linger after my cold has gone?
It’s common for a cough to continue after the other symptoms of a cold have improved because the airways can remain irritated and sensitive. Most coughs settle on their own within a few weeks. If your cough lasts for more than three weeks, speak to a clinician or pharmacist for further advice.
4. Can children take the same cough medicines as adults?
No. Cough and cold medicines have different age restrictions and doses for children. Some products are not suitable for younger children, so always check the label carefully. If you’re unsure, speak to a clinician or pharmacist for age-appropriate advice rather than using an adult dose.
