Common use

Dulcolax is commonly used for the relief of occasional constipation in adults and children over 6 years of age. It is particularly useful when bowel movements become infrequent, difficult, or painful due to various factors including dietary changes, travel, medication side effects, or temporary lifestyle disruptions. Healthcare providers may also recommend Dulcolax for bowel preparation before certain medical procedures, such as colonoscopy or rectal surgery, though such use should only be undertaken under medical supervision. The product is intended for short-term use, typically not exceeding 7 days, unless directed by a healthcare professional.

Dosage and direction

Adults and children 12 years and older:

• Tablets: 1–3 tablets (5–15 mg) taken orally once daily, preferably at bedtime
• Suppositories: 1 suppository (10 mg) inserted rectally once daily

Children 6–11 years:

• Tablets: 1 tablet (5 mg) taken orally once daily, preferably at bedtime
• Suppositories: 1 suppository (10 mg) inserted rectally once daily (under adult supervision)

Tablets should be swallowed whole with a full glass of water; do not crush or chew. Take tablets on an empty stomach for optimal effectiveness. Suppositories should be unwrapped and inserted pointed end first into the rectum. Remain lying down for 15–20 minutes after insertion if possible. Do not use for more than 7 days unless directed by a physician.

Precautions

Do not use if you are allergic to bisacodyl or any other ingredient in Dulcolax. Consult a healthcare provider before use if you have nausea, vomiting, abdominal pain, or sudden change in bowel habits that persists for more than 2 weeks. Use with caution in patients with pre-existing electrolyte imbalances. Prolonged use may lead to dependence on laxatives for bowel movements. Discontinue use and consult a healthcare provider if rectal bleeding occurs or if you do not have a bowel movement after using the product. Pregnant or breastfeeding women should consult a healthcare professional before use.

Contraindications

Dulcolax is contraindicated in patients with known hypersensitivity to bisacodyl or any component of the formulation. It should not be used in cases of intestinal obstruction, acute surgical abdomen, appendicitis, inflammatory bowel diseases (such as Crohn’s disease or ulcerative colitis), or severe abdominal pain with nausea and vomiting. Contraindicated in children under 6 years of age. Do not use in patients with acute constipation associated with impacted feces until the impaction has been resolved.

Possible side effects

Common side effects may include abdominal discomfort, cramping, gas, and mild nausea. These effects are usually transient and diminish with continued use or dosage adjustment. Less frequently, patients may experience dizziness, weakness, or rectal irritation (with suppository use). Rare but serious side effects include severe abdominal pain, rectal bleeding, electrolyte imbalance (manifesting as muscle cramps, weakness, dizziness), or allergic reactions (rash, itching, swelling). Discontinue use and seek medical attention if severe side effects occur.

Drug interaction

Bisacodyl may decrease the absorption of other orally administered medications if taken simultaneously due to accelerated gastrointestinal transit time. Separate administration of other oral medications by at least 2 hours from Dulcolax intake. Concurrent use with other laxatives may increase the risk of electrolyte disturbances. Use with caution with diuretics or corticosteroids, which may exacerbate electrolyte imbalances. Antacids or medications that reduce stomach acidity may cause premature dissolution of the enteric coating, leading to gastric irritation.

Missed dose

If a dose is missed, take it as soon as remembered unless it is almost time for the next dose. Do not double the dose to make up for a missed one. Since Dulcolax is typically used as needed for constipation relief rather than on a fixed schedule, the concept of “missed dose” primarily applies when using the product under medical direction for bowel preparation.

Overdose

Overdose may result in severe cramping, abdominal pain, diarrhea, dehydration, and electrolyte imbalance. Symptoms of electrolyte disturbance may include muscle cramps, weakness, dizziness, and irregular heartbeat. In case of suspected overdose, seek immediate medical attention or contact a poison control center. Treatment is supportive and may include fluid and electrolyte replacement. Do not induce vomiting unless directed by medical personnel.

Storage

Store at room temperature (20–25°C or 68–77°F) in a dry place protected from light and moisture. Keep suppositories in their original foil wrapping until ready to use. Keep out of reach of children and pets. Do not use after the expiration date printed on the packaging. Properly discard any unused medication that has expired or is no longer needed.
