Covonia Linctus

Glycerol is the active ingredient in Covonia. It works as a demulcent, a medicine that forms a soothing coat over the lining of the throat, which reduces the coughing impulse and relieves any associated pain and discomfort in the throat.

It's true there's a limited amount of evidence to support the effectiveness of cough medicines. That said, some people do find linctuses like Covonia to be helpful, and it's a very safe medicine that rarely causes any side effects – so you may think it's worth a try.

Covonia Linctus is recommended to relieve the irritation and discomfort of a cough. It will not treat the underlying cause or make any infection clear more quickly. Therefore, you should use it for a few days, as needed. You can take it up to four times a day - check the label to check you have the right dose if this is for your child, as doses are suggested by age.

Do not take Covonia Linctus products if you have previously had an allergic reaction to glycerol or another ingredient listed in the medication. You may have reasons to avoid alcohol, so be aware that some Covonia Linctus products may contain trace amounts of alcohol.

Speak with your doctor or pharmacist before taking Covonia Linctus products if you are pregnant or breastfeeding or have an intolerance to certain sugars like fructose.

Occasionally, a cough can be a symptom of a more severe condition. Do speak to your doctor if you have had a cough for more than three weeks, are coughing up blood, have lost weight unexpectedly, or have chest pain or shortness of breath.

If you are coughing up mucus (chesty cough), you should try a type of medicine called an expectorant instead, such as guaifenesin.
