10 Best Laxative 2026 in the United States

MiraLAX Gentle Constipation Relief Laxative Powder is an osmotic laxative designed to help relieve occasional constipation. It works by drawing water into the colon to hydrate and soften stool, making it easier to pass within 1-3 days. Unlike stimulant laxatives that can cause immediate and sometimes harsh effects, MiraLAX is known for its gentle action without causing gas, bloating, cramping, or sudden urgency. This makes it suitable for those who prefer a mild and gradual relief from constipation.

It's also noteworthy that MiraLAX is the #1 physician-recommended OTC laxative brand, which adds to its credibility and trustworthiness. To use, simply dissolve the powder in a beverage of choice, as it has no added taste or grit, making it easy to consume. The product is free from gluten, sugar, and preservatives, which may be beneficial for those with dietary restrictions.

However, it's important to consider that the onset of action is not immediate, so it might not be the best choice for those seeking quick relief. Additionally, frequent use is not recommended as it is intended for occasional constipation. MiraLAX provides a gentle and effective option for those looking for a reliable stool softener without harsh side effects.

Amazon Basic Care ClearLax uses Polyethylene Glycol 3350 as its active ingredient, which is an osmotic laxative. This type of laxative works by drawing water into the bowel to help soften stools and increase bowel movement frequency. It generally takes 1 to 3 days to produce results, making it suitable for relieving occasional constipation rather than immediate relief.

The product is unflavored and dissolves well in any beverage, which can be a plus for those who dislike the taste of flavored laxatives. It is also grit-free, sugar-free, and gluten-free, catering to various dietary preferences and needs. One significant advantage is that Polyethylene Glycol 3350 is the number one doctor-recommended laxative active ingredient, which adds a level of trust and reliability.

It is essential to note that this laxative is intended for adults and children over 17, limiting its use for younger children. Additionally, since the onset of action is 1 to 3 days, it may not be suitable for those needing quick relief. Users should also be aware of potential side effects like bloating, gas, or an upset stomach, which are common with osmotic laxatives. Despite these considerations, the product's formulation and effectiveness for occasional constipation make it a reliable option for many adults.

Dulcolax Stimulant Laxative Tablets are designed to offer effective and predictable relief from occasional constipation. This product contains bisacodyl, which stimulates bowel movement, helping to combat symptoms like straining and bloating. A key strength is its relatively fast onset of action, typically providing relief within 6 to 12 hours, making it a convenient option for overnight use.

The tablets are comfort-coated, making them easier to swallow and reducing potential discomfort during ingestion. Each box includes 100 tablets, suitable for regular use, especially handy for travelers or those experiencing stress-induced irregularity. Dulcolax is a well-regarded brand, frequently recommended by doctors for its dependability in restoring natural gut rhythm.

However, as a stimulant laxative, it is important to use it as directed to minimize side effects, which can include abdominal discomfort or cramping. Overuse or prolonged use may lead to dependency, so it's best suited for occasional use rather than as a daily solution. This product is a solid choice for those needing quick and reliable relief from constipation, but users should be mindful of the potential for side effects and use it within the recommended guidelines.
