Speak to your pharmacist if you have a cough. They can give you advice or suggest treatments to help you cough less, like cough syrups and lozenges. These won’t get rid of the cough. 
Some cough medicines shouldn’t be given to children under 12. 
Book an appointment to see your GP if you have any of the following symptoms along with your cough:

• you’ve had a cough for more than 3 weeks (persistent cough)
• your cough is very bad or quickly gets worse, for example – you have a hacking cough or can’t stop coughing
• you have chest pain
• you’re losing weight for no reason
• the side of your neck feels swollen and painful (swollen glands)
• you find it hard to breathe
• you have a weakened immune system, for example because of chemotherapy or diabetes

See a GP urgently if you’re coughing up blood.
