What Chlorvescent is used for
Chlorvescent tablets are used to provide extra potassium for people who have lost potassium from their bodies because of illness
or treatment with certain medicines. It is also used for people who do not have enough potassium in their regular diet or
cannot replace the potassium they have lost from their diet alone.
Potassium is essential for life and health. Vegetables, potatoes and fruit are good sources of dietary potassium.
However, as too much potassium can be harmful, do not change your dose without first checking with your doctor.
The dose of Chlorvescent may need to be adjusted if your diet is rich in natural sources of potassium.
Ask your doctor if you have any questions about why Chlorvescent has been prescribed for you.
Your doctor may have prescribed it for another purpose.
