Dulcolax is a clinically trusted, over-the-counter laxative designed to provide reliable relief from occasional constipation. Its active ingredient, bisacodyl, is a stimulant laxative that works directly on the colon to encourage bowel movement, making it a preferred choice for both patients and healthcare professionals. Suitable for adults and children over a certain age, it offers a predictable onset of action, typically within 6 to 12 hours when taken orally. Available in various forms including coated tablets and suppositories, Dulcolax provides flexible options to meet individual needs and preferences, ensuring comfort and efficacy.

Features

• Active ingredient: Bisacodyl (5 mg per tablet in standard adult dosage)
• Formulations: Enteric-coated tablets for oral use; rectal suppositories
• Onset of action: Tablets: 6–12 hours; Suppositories: 15–60 minutes
• Non-habit forming when used as directed for occasional constipation
• Sugar-free, gluten-free, and suitable for vegetarians (tablet coating is plant-derived)
• Available without a prescription in most regions

Benefits

• Provides predictable relief from occasional constipation, typically overnight when taken at bedtime.
• Stimulates natural peristalsis in the colon, promoting a comfortable bowel movement.
• Flexible administration: oral tablets for planned relief, suppositories for faster action.
• Does not interfere with the digestive process of the upper gastrointestinal tract due to enteric coating.
• Trusted by healthcare providers and used in clinical settings for bowel preparation.
• Minimal systemic absorption, focusing action locally in the bowel.

Common use

Dulcolax is commonly used for the relief of occasional constipation. It is also frequently recommended for bowel cleansing prior to diagnostic procedures such as colonoscopy, often in combination with other laxatives as per medical advice. It can be used to establish regularity after surgery, childbirth, or when opioid use causes constipation. It is not intended for long-term daily use without medical supervision.

Dosage and direction

Adults and children 12 years and older (oral tablets): 1 to 3 tablets (5 mg to 15 mg) taken orally, swallowed whole with a full glass of water. Do not chew or crush. Best taken at bedtime for predictable relief the next morning.
Suppositories: 1 suppository (10 mg) inserted rectally, as needed.
Children under 12: Use only under the direction of a physician.
Do not use for more than 7 days unless directed by a doctor. Taking with milk or antacids may cause premature dissolution of the coating; avoid concurrent use.

Precautions

Do not use if you are allergic to bisacodyl or any inactive ingredients. Consult a doctor before use if you have nausea, vomiting, abdominal pain, or a 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 or electrolyte disturbances. Not recommended during pregnancy or breastfeeding except under medical advice. Keep out of reach of children.

Contraindications

Dulcolax is contraindicated in patients with known hypersensitivity to bisacodyl. Do not use in cases of acute surgical abdomen, appendicitis, inflammatory bowel diseases (such as Crohn’s disease or ulcerative colitis), intestinal obstruction, or severe abdominal pain with nausea and vomiting. Contraindicated in patients with acute dehydration or those with ileostomy.

Possible side effects

Common side effects may include abdominal discomfort, cramping, gas, and mild nausea. These are generally mild and temporary. Less frequently, dizziness or lightheadedness may occur. Rectal administration may cause mild burning or irritation. Excessive use may lead to diarrhea, dehydration, electrolyte loss (such as hypokalemia), and weakness. Severe or persistent abdominal pain, rectal bleeding, or allergic reactions (rash, itching, swelling) warrant discontinuation and medical attention.

Drug interaction

Antacids or medications that reduce stomach acidity may cause the enteric coating of Dulcolax tablets to dissolve prematurely, potentially leading to stomach irritation or cramping. Do not take within 1 hour of consuming milk or antacids. Concomitant use with other laxatives may increase the risk of electrolyte imbalance. Use with caution alongside diuretics, corticosteroids, or heart rhythm medications, as hypokalemia may potentiate their effects.

Missed dose

Dulcolax is used on an as-needed basis for occasional constipation. It is not intended for regular scheduled dosing. If you miss a planned dose for bowel preparation, follow your doctor’s instructions. Do not double the dose.

Overdose

Overdose may lead to severe cramping, diarrhea, dehydration, and electrolyte imbalance. Symptoms can include muscle cramps, weakness, dizziness, and in severe cases, cardiac arrhythmias. Treatment is supportive and includes discontinuation, fluid and electrolyte replacement. Seek immediate medical attention or contact a Poison Control Center in case of suspected overdose.

Storage

Store at room temperature (15–30°C or 59–86°F). Keep tablets in their original container, away from moisture and light. Suppositories may be stored in a cool place; some formulations may require refrigeration—check product packaging. Keep out of reach of children and pets.
