If you take too many tablets, consult your doctor and take this leaflet with you.

It may be harmful to take too much of this medicine or take it for too long. This is because it may lead to - A ‘lazy bowel’, where the muscle in the bowel becomes too relaxed. This means that bowel emptying happens less often. This can lead to long-term constipation.

  • Imbalance of fluids and salts in the body. This can affect the tightness of muscles such as those in the bowel. It can also affect the salts in the blood. - Low levels of potassium in the blood (called hypo-kalaemia). This can make you tired, dizzy, make your muscles weak and cause an uneven heart-beat.
  • Dehydration, making you thirsty, feel faint and giving you headaches. It can also mean that you cannot pass enough urine.

If you miss a dose, take your next dose at the usual time. Do not take two doses at the same time to make up for the missed dose.

Always consult your doctor if you need further advice.
