Medication Information Leaflet
Cough suppressants are a group of medications which work by stopping the urge to cough and reducing cough. Cough suppressants may contain ingredients such as codeine, dextromethorphan, promethazine and diphenhydramine. They may be found as either liquids, tablets, capsules or lozenges.
They may also be found in combination with other ingredients for relief of runny or blocked nose.
- Take these medications as recommended by your healthcare professional. Consult your healthcare professional if you are not sure how to take these medications correctly.
- These medications may be taken with or without food
- For syrups, shake the bottle well before use.
- If your symptoms do not go away or worsen after one week of taking these medications, please speak to your healthcare professional.
Cough suppressants may be taken when required for a short period of time. This means that you do not have to take them if you do not have any symptoms. If you miss a dose, take it as soon as you remember. However, if it is almost time for your next dose, skip the missed dose and continue normally.
