Further information

1. What Dytac 50mg Capsules are and what they are used for
Dytac 50mg Capsules belong to a group of medicines called diuretics. They help the kidneys remove water from the
body. Dytac 50mg Capsules act by stopping potassium being lost from the body. The capsules are used to treat
oedema which is a build-up of fluid in the body. This may occur in many situations, for instance during treatment with
steroids, with liver and kidney problems or with heart failure (when the heart doesn’t pump efficiently).
Dytac 50mg Capsules can be used with another type of diuretic which normally allows potassium to be lost from the
body. This combination increases the amount of water being removed and prevents potassium loss at the same time.
