How Long Does It Take for Diurex to Work?

Updated April 17, 2017

Diurex is a water pill containing a gentle diuretic, a substance that increases the flow of urine and is meant to promptly increase the outflow of excess body water, leading to temporary water weight loss and helping alleviate other ailments.


Because Diurex helps the body release excess water, it can allow for temporary weight loss and relief from bloating. It's generally directed to women, as relief from other menstrual symptoms such as puffiness, pressure related cramps, headaches, backaches and breast tenderness.


Diurex is meant to expel excess body water, starting one to two hours after a dose has been taken as long as the person using it drinks plenty of water. Diurex, and other diuretics, allow the kidneys to expel water and salts more quickly, leading to less water weight and bloat.

Side Effects

Due to its quick action on the body, Diurex may cause certain side effects. Among those are muscle cramps, diarrhoea, dizziness, vomiting, joint pain, muscle weakness, skin rash and increased sensitivity to sunlight. However, frequent urination is mainly what happens when a person takes Diurex, and this may be effective for 12 to 24 hours.
