🚻 Say Goodbye to Constipation — A Pharmacist’s Complete Guide to Laxatives

Feeling bloated or having trouble going to the bathroom lately? You’re not alone — constipation is one of the most common issues people experience, especially with today’s busy lifestyle and lack of fibre in the diet. While good habits and hydration are essential, sometimes you need a little extra help. Here’s a pharmacist’s breakdown of the different types of laxatives available in Canada, so you can find the one that works best for your body. 🌾 1. Bulk-Forming Laxatives

Examples: Metamucil, Fybogel

These are the most natural and gentle types of laxatives.They work by absorbing water in the intestines, increasing stool volume and softness so it passes more easily.The main ingredient is psyllium husk, a plant-based fibre that expands when mixed with water.

✅ Best for: People with low fibre intake or irregular bowel movements ⚠️ Be careful: Always drink plenty of water when using these. Without enough fluid, your constipation could actually worsen.

Safe for long-term use, bulk-forming laxatives are a great first option for mild or occasional constipation.

💧 2. Osmotic Laxatives

Key ingredients: Polyethylene Glycol (PEG), Lactulose

These draw water into the colon through osmosis, softening stool and making it easier to pass. They’re safe for children, adults, and seniors alike — and especially helpful for chronic constipation or those recovering from surgery.

PEG isn’t absorbed by the body, making it very safe, while Lactulose also helps promote healthy gut bacteria. Results usually appear within 24 to 72 hours, so this option requires a bit of patience but is gentle on your system.

⚡ 3. Stimulant Laxatives

Examples: Dulcolax (Bisacodyl), Senna

This group stimulates the muscles in the intestines to contract and move stool along more quickly. It’s a fast-acting option — usually working within 6 to 12 hours, so many people take it at bedtime for results the next morning.

⚠️ Use only occasionally, as long-term or frequent use may weaken natural bowel function over time.Ideal for short-term relief or bowel prep before medical procedures.

🪔 4. Stool Lubricants

Example: Colace (Docusate Sodium)

This type acts like a lubricant, helping stool retain moisture and slide through more easily.

It’s considered safe for pregnant women and seniors, and it’s gentle on the body.

However, taking too much can sometimes cause mild cramps or nausea,

so always stick to the recommended dosage.

💉 5. Enemas

Example: Fleet Enema

For immediate relief, enemas can be highly effective.

They work by introducing liquid directly into the rectum to soften and loosen stool.

Results appear within minutes, but overuse can disturb your natural gut balance —

so it’s best reserved for occasional, emergency situations only.

🦠 6. Probiotics

Examples: Probiotic Probiotique, Jamieson Probiotic 10 Billion

Probiotics help restore the balance of healthy bacteria in your gut, which can naturally improve digestion and regularity over time. Common strains like Lactobacillus and Bifidobacterium have been shown in studies to improve constipation symptoms by 10–40% when taken for four or more weeks. They’re also great for reducing bloating and supporting overall gut health —think of them as daily maintenance for your digestive system.

💡 Pharmacist’s Advice

Constipation isn’t just about digestion — it’s often linked to diet, hydration, and lifestyle. Before reaching for medication, try increasing your fibre intake, drinking more water, and maintaining a regular eating and exercise routine. But if those changes aren’t enough, the right laxative — used correctly — can safely get things moving again.
