Dulcolax is a leading over-the-counter laxative medication designed to provide reliable and effective relief from occasional constipation. Its active ingredient, bisacodyl, is a stimulant laxative that works directly on the colon to encourage bowel movement, offering predictable results typically within 6 to 12 hours when taken at bedtime. Trusted by healthcare professionals and used by millions worldwide, Dulcolax is formulated to restore comfort and regularity with a well-understood mechanism of action. This product is available in various forms, including coated tablets and suppositories, to suit individual patient needs and preferences under medical guidance.

Features

• Mechanism of Action: Stimulant laxative that directly irritates the colonic mucosa and stimulates colonic peristalsis
• Onset of Action: Tablets: 6–12 hours; Suppositories: 15–60 minutes
• Formulations: Enteric-coated oral tablets and rectal suppositories
• Non-Habit Forming: When used occasionally and as directed

Benefits

• Provides predictable relief from occasional constipation, typically overnight when tablets are taken at bedtime
• Dual-format options allow for personalized treatment: oral for planned relief, rectal for faster action

• Minimizes straining, which can be beneficial for patients with hemorrhoids or cardiovascular concerns
• Does not interfere with the absorption of nutrients or other orally administered medications due to local action in the colon
• Trusted efficacy with a long history of clinical use and safety monitoring

Common use

Dulcolax is commonly used for the temporary relief of occasional constipation. It is also frequently recommended to prepare the bowel for diagnostic procedures such as colonoscopy, or in situations where defecation needs to be facilitated, such as post-surgical recovery or for patients with certain medical conditions causing reduced motility. It is not intended for long-term daily use but serves as an effective short-term solution to re-establish regularity.

Dosage and direction

For adults and children 12 years and older:

• 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 results the next morning.
• Suppositories: 1 suppository (10 mg) inserted rectally, once daily.

Do not use for more than 7 days unless directed by a physician. For children under 12 years, consult a healthcare provider before use. Take tablets on an empty stomach for optimal effect. Do not take antacids or milk within 1 hour of taking Dulcolax tablets, as this may cause premature dissolution of the coating.

Precautions

• Use only as directed; prolonged or excessive use may lead to dependency or electrolyte imbalance.
• Not recommended for use in children under 6 years of age.
• Patients with sudden changes in bowel habits lasting more than 2 weeks should consult a healthcare professional before use.
• Those with nausea, vomiting, or abdominal pain should avoid use and seek medical advice.
• Stay adequately hydrated during use to support bowel function and minimize discomfort.
• If rectal bleeding occurs or if no bowel movement occurs after use, discontinue and consult a physician.

Contraindications

Dulcolax is contraindicated in individuals with:

• Known hypersensitivity to bisacodyl or any component of the formulation
• Acute surgical abdomen, appendicitis, or symptoms such as nausea, vomiting, or undiagnosed abdominal pain
• Acute inflammatory bowel diseases (e.g., Crohn’s disease, ulcerative colitis)
• Intestinal obstruction or severe dehydration
• Severe electrolyte disturbances

Possible side effect

While generally well-tolerated when used occasionally and as directed, some individuals may experience:

• Abdominal discomfort, cramping, or pain
• Nausea
• Diarrhea or loose stools
• Electrolyte imbalance (with prolonged or excessive use)
• Dizziness or weakness
• Rectal irritation (with suppository use)

These effects are usually mild and transient. If severe or persistent, discontinue use and consult a healthcare provider.

Drug interaction

Bisacodyl may interact with certain medications:

• Antacids or proton pump inhibitors: May cause premature dissolution of the enteric coating, leading to stomach irritation or reduced efficacy.
• Diuretics or corticosteroids: Concurrent use may increase the risk of electrolyte imbalance.
• Other laxatives: Concomitant use is not recommended due to increased risk of adverse effects.
• Medications affected by rapid gastrointestinal transit: Theoretical potential for reduced absorption.

Always inform your healthcare provider of all medications you are taking, including over-the-counter products and supplements.

Missed dose

Dulcolax is used on an as-needed basis for occasional constipation. It does not require a regular dosing schedule. If a dose is missed, it is not necessary to double the next dose. Simply take the next dose when needed, following the recommended dosage instructions.

Overdose

Overdose may lead to severe cramping, diarrhea, dehydration, and electrolyte imbalance. Symptoms can include weakness, dizziness, and fainting. In case of suspected overdose, seek medical attention immediately. Treatment is supportive and may include fluid and electrolyte replacement. Do not induce vomiting.

Storage

Store at room temperature (20–25°C or 68–77°F). Keep away from moisture, light, and heat. Suppositories may become soft at higher temperatures but will firm up again if cooled. Keep out of reach of children. Do not use after the expiration date printed on the packaging.
