What Dulcolax SP Drops is used for

Dulcolax SP Drops is used to treat constipation.

Dulcolax SP Drops works by acting on the lining of the lower bowel to stimulate movement and promotes accumulation of water into the bowel to produce soft formed stools.

Sodium picosulfate, the active ingredient in Dulcolax SP Drops, is ineffective in altering the digestion or absorption of calories in the small intestine and therefore does not assist with weight loss.

How long to take it

Dulcolax SP Drops is recommended for short-term use only. If symptoms persist seek medical advice.

Long-term use of Dulcolax SP Drops is not recommended. If you take Dulcolax SP Drops every day you should consult with your doctor to find out the cause of your constipation. Long-term or excessive use of Dulcolax SP Drops may cause an imbalance of salts in your body including lowering potassium levels in the blood and an excessive loss of water from your body. It may also cause the bowel to become dependent on Dulcolax SP Drops to produce a bowel motion.

If you take too much (overdose)

Seek medical advice immediately if you have taken more than the recommended or prescribed dose of Dulcolax SP Drops. Advice can be provided by a doctor, pharmacist or Poisons Information Centre (telephone 13 11 26).

Signs of overdose may include diarrhoea and abdominal cramps as well as other medical problems caused by a loss of salts and water from your body. Damage to the lining of the large bowel may also occur.

As with other laxatives, persistent overdose may cause diarrhoea, abdominal pain, imbalance of salts in the body (including low potassium), secondary hyperaldosteronism and kidney stones. If an imbalance of salts (low potassium) occurs, then kidney disease, metabolic alkalosis and muscle weakness may be experienced.
