Who Should Not Take Dulcolax Tablets?

Dulcolax Tablets are designed for short-term relief of occasional constipation, but they are not suitable for everyone. If you are unsure whether this medicine is right for you, consult your doctor or pharmacist before use.

Do Not Take Dulcolax Tablets If You:

  • Are allergic to bisacodyl or any other ingredients in this medication (refer to the patient information leaflet).

Is Dulcolax Safe for Weight Loss?

Dulcolax and other stimulant laxatives are not effective or safe for weight loss. They do not reduce calorie absorption and are not a substitute for a healthy diet or exercise.

Although laxatives may temporarily cause water loss, any weight reduction is due to dehydration, not fat loss.

Dangers of Misusing Laxatives for Weight Loss

Using laxatives incorrectly can lead to serious health risks, including:

  • Electrolyte and mineral imbalances – Disrupting sodium, potassium, magnesium, and phosphorus levels can affect muscle and nerve function, including those in the heart and colon.
  • Severe dehydration – Symptoms include tremors, weakness, blurred vision, fainting, kidney damage, and, in extreme cases, death. Dehydration may require emergency medical treatment.
  • Digestive system damage – Overuse of laxatives can cause long-term harm to your intestines and should be avoided.

  • If you are pregnant, trying to conceive, or breastfeeding, consult your doctor or pharmacist before using Dulcolax Tablets.

  • If you have fructose intolerance, galactose intolerance, total lactase deficiency, glucose-galactose malabsorption, or sucrase-isomaltase insufficiency, you should not take this medication.

Do Dulcolax Tablets Interact with Other Medicines?

Before taking Dulcolax Tablets, inform your doctor or pharmacist if you are currently taking, have recently taken, or plan to take any other medications. Some medicines may affect how Dulcolax works, while Dulcolax can also influence the effectiveness of other medications.

Medications That May Interact with Dulcolax Tablets

If you are taking any of the following, speak to your doctor or pharmacist before using Dulcolax:

  • Diuretics (water tablets) – Used to reduce fluid retention (e.g., bendrofluazide, furosemide (frusemide)).

  • Other laxatives – Using multiple laxatives together may increase the risk of dehydration or electrolyte imbalance.
