Dulcolax Soft Chews are chewed thoroughly and swallowed with a full 8-ounce glass of water. Adults take 2 to 4 chews per day, and most people can expect a bowel movement within 30 minutes to 6 hours.
Dosage by Age
The recommended dose depends on your age group:
- Adults and children 12 and older: 2 to 4 chews per day
- Children 6 to under 12: 1 to 2 chews per day
- Children 4 to under 6: 1 chew per day
- Children under 4: not recommended without a doctor’s guidance
You can take the full dose at once or split it into smaller doses throughout the day. Do not exceed the maximum daily amount listed for your age group within any 24-hour period.
How to Take Them
Chew the pieces completely before swallowing. The most important step people skip is drinking a full glass of liquid (8 ounces) with each dose. Water is ideal, but any liquid works. The fluid helps the active ingredient, magnesium hydroxide, draw water into your intestines and soften stool so it moves through more easily.
You can take them with or without food. There’s no specific time of day that works best, though many people prefer taking them in the evening or morning so the bowel movement happens at a predictable time. Since the effect can kick in as quickly as 30 minutes, plan to be near a bathroom.
Soft Chews vs. Dulcolax Tablets
These are not the same product in a different form. Dulcolax Soft Chews contain magnesium hydroxide, an osmotic laxative that pulls water into the bowel. The classic Dulcolax tablets contain bisacodyl, a stimulant laxative that triggers contractions in the intestinal muscles. The chews work faster (30 minutes to 6 hours) and tend to produce a gentler effect, while bisacodyl tablets typically take 6 to 12 hours.
Dulcolax also makes a product called “Chewy Fruit Bites,” which has a different dosing schedule: 4 chews for adults (up to 8), and 2 chews for children 6 to under 12 (up to 4). Check the specific product name on your package so you’re following the right instructions.
Who Should Be Cautious
Because these chews contain magnesium, your kidneys need to be working normally to clear the extra magnesium from your body. People with kidney disease or those on a magnesium-restricted diet should talk to a doctor before using them. The same applies if you’re pregnant or breastfeeding.
Skip this product and get medical advice first if you currently have stomach pain, nausea, vomiting, or a sudden change in bowel habits that has lasted more than two weeks. These symptoms could point to something that a laxative won’t fix and might mask.
If you take prescription medications, check with a pharmacist before adding these chews. Magnesium-based laxatives can interfere with how some drugs are absorbed.
Side Effects and Warning Signs
The most common side effects are mild cramping and loose stools. These usually pass once the laxative effect wears off. Taking too many chews can cause nausea, vomiting, diarrhea, and dehydration, especially in children.
In rare cases, particularly in people with reduced kidney function, magnesium can build up to unsafe levels. Signs of this include confusion, drowsiness, facial flushing, muscle weakness, and an irregular heartbeat. Stop taking the chews and get medical attention if you notice any of these.
If you have rectal bleeding or no bowel movement at all after taking the product, that warrants a call to your doctor. These can be signs of a more serious condition.
How Long You Can Use Them
Dulcolax Soft Chews are designed for occasional constipation relief, not daily long-term use. Using any osmotic laxative regularly can disrupt your body’s electrolyte balance, particularly sodium, potassium, and magnesium levels. If you find yourself reaching for them more than a few days in a row, that’s a signal to look into what’s causing the constipation rather than continuing to treat the symptom.
