Expert Review


Leftose has been prescribed by doctors for over 40 years. You will probably have encountered or used Leftose without realising it, as doctors usually prescribe them in a strip of 10 small tablets in a clear dispensing bag.

As most sore throats are caused by inflammation which results in pain, Leftose works by reducing the inflammation and swelling, thus reducing the pain. Thick mucus or phlegm when stuck in the throat can also cause a lot of discomfort for those with chesty coughs. Leftose breaks down the phelgm, making it easier to cough out, and thus providing relief.

Leftose can be used together with lozenges which often provide just temporary relief. However, the plus point of Leftose is that it doesn't numb the tongue like many lozenges do, which can make eating or tasting food less pleasant. It being in a tablet form also provides convenience as compared to (cough) syrup bottles which can be quite cumbersome to bring to work.

For real relief real fast, one can take 3 doses 3 times a day which can really help to relieve symptoms very quickly. However, should infection persist, antibiotics may be needed.
