About Constipation
Constipation is a common digestive condition characterized by infrequent, hard, or difficult-to-pass bowel movements. It occurs when stool moves too slowly through the intestines, allowing too much water to be absorbed—resulting in dry, firm stool that is harder to eliminate. Common contributing factors include low fiber intake, inadequate hydration, lack of physical activity, changes in routine or travel, certain medications (such as opioids or iron), and stress.
​
Symptoms often extend beyond just fewer bowel movements. Many people experience bloating, abdominal discomfort, straining, and a sensation of incomplete evacuation after using the bathroom. While occasional constipation is common, persistent symptoms can interfere with daily comfort and quality of life.
​
How to Manage Constipation
Constipation can often be managed with over-the-counter (OTC) options that soften stool, increase bowel movement frequency, and reduce straining.
-
Fiber supplements (such as psyllium or methylcellulose) add bulk to the stool and promote regularity when taken daily with adequate fluids.
-
Stool softeners (like docusate) draw water into the stool, making it easier to pass.
-
Osmotic laxatives (such as polyethylene glycol/Miralax®) pull water into the colon to provide more consistent relief and are suitable for short-term use.
-
Stimulant laxatives (like senna or bisacodyl) trigger bowel contractions and should be used occasionally for quick relief rather than daily maintenance.
​​
Lifestyle habits are equally important. Drink plenty of water, stay physically active, and respond promptly to the urge to have a bowel movement. These steps help OTC treatments work more effectively and reduce recurrence.​

​
🟩 Stool Softner (Docusate sodium)🔗→
Docusate sodium is best used for hard, dry stools that are painful to pass. It is commonly recommended after surgery, childbirth, or during hemorrhoid flare-ups to reduce straining. It works by drawing water into the stool, making it softer and easier to pass without stimulating the intestines.
**Pharmacist Tip**
-
Take with a full glass of water and maintain adequate fiber intake for best results.
-
Stool softeners are most effective for prevention and easing stool passage, not for immediate relief of severe constipation.
-
Relief is gradual, typically occurring within 12–72 hours, and it is gentle enough for short-term or occasional longer use when needed.
​​
🟩 Senna (e.g., Senokot®)🔗→
Senna is a stimulant laxative used for occasional constipation when faster relief is needed. It works by stimulating the intestinal muscles to promote bowel movement activity. It typically produces a bowel movement within 6–12 hours, which is why it is often taken at bedtime for a morning result.
**Pharmacist Tips**
-
Use for short-term relief only.
-
Avoid daily or long-term use unless directed by a healthcare professional, as overuse may lead to cramping, dependence, or reduced natural bowel function.
-
Stay well hydrated while using stimulant laxatives.
​​
🟩 Bisacodyl (e.g., Dulcolax®) Tablets or Suppositories🔗→
Bisacodyl is a stimulant laxative used for short-term relief of constipation, especially when symptoms have not improved with fiber supplements or stool softeners. It works by stimulating bowel contractions to help move stool through the colon.
**Pharmacist Tips**
-
Use occasionally for quick relief rather than daily.
-
Regular or long-term use may cause abdominal cramping or dependence unless advised by a healthcare professional.
-
Swallow tablets whole, do not crush or chew, and avoid taking them with milk or antacids.
-
Oral tablets typically produce a bowel movement within 6–12 hours, while rectal suppositories act faster, usually within 15–60 minutes.
​​
🟩 Senna + Docusate (e.g., Senokot-S®, Senna-S)
This combination product is helpful when stools are both hard and infrequent, particularly in more stubborn cases of constipation. It combines docusate, a stool softener that adds moisture to make stool easier to pass, with senna, a stimulant laxative that triggers intestinal contractions to promote a bowel movement. It typically works within 6–12 hours, making it convenient for overnight relief.
**Pharmacist Tips**
-
Best used short term for temporary constipation.
-
Prolonged daily use should be avoided unless directed by a healthcare professional, as regular stimulant use may lead to dependence or cramping.
-
Swallow tablets whole, do not crush or chew.
-
Stay well hydrated while taking this medication.
​​
🟩 Psyllium Fiber (e.g., Metamucil®)🔗→
Psyllium is a bulk-forming fiber supplement best used for daily prevention and long-term management of chronic constipation. It works by absorbing water in the intestines, adding bulk and softness to the stool, which helps promote regular bowel movements.
**Pharmacist Tips**
-
Mix with a full glass of water and drink promptly, then follow with another glass of water.
-
Adequate hydration is essential, taking fiber without enough fluids can worsen constipation or cause blockage.
-
Expect results within 1–3 days with consistent use.
-
In addition to supporting digestive health, psyllium may also help improve cholesterol levels when taken consistently.
​​
🟩 Polyethylene Glycol(PEG)(e.g., MiraLAX®)🔗→
Polyethylene glycol (PEG) is an osmotic laxative suitable for frequent or chronic constipation when gentle, consistent relief is needed. It works by drawing water into the colon, softening stool and increasing bowel movement frequency without usually causing significant cramping. It is commonly used for consistent, predictable relief.
**Pharmacist Tips**
-
Use the bottle cap to measure the correct dose (fill to the marked line), then dissolve the powder completely in 4–8 ounces of water, juice or another beverage before drinking.
-
It typically works within 1–3 days. Maintain good hydration and consult a healthcare provider if long-term use becomes necessary.
​​
🟩 Milk of Magnesia🔗→
Milk of Magnesia (magnesium hydroxide) is an osmotic laxative helpful for occasional constipation when relatively faster relief is desired. It works by drawing water into the intestines, which softens stool and stimulates a bowel movement.
**Pharmacist Tips**
-
Use short term for temporary relief and drink plenty of fluids while taking it.
-
Avoid use if you have kidney disease or are on a magnesium-restricted diet unless directed by a healthcare professional.
-
Do not exceed the recommended dose.
-
It typically produces results within 30 minutes to 6 hours, depending on the dose and individual response.
​​
🟩 Fleet® Saline Enema​​​​​🔗→
Fleet® Saline Enema is used for urgent relief of constipation when oral treatments have not worked or cannot be used. It contains a saline solution that draws water into the rectum, softening stool and stimulating a bowel movement.
How to Use: Remove the protective cap and lubricate the tip if needed. Lie on your left side with your right knee bent (or kneel and lean forward), gently insert the applicator tip into the rectum, and squeeze the bottle until most of the liquid is emptied. Remove the tip and try to hold the solution in place until the urge to have a bowel movement is strong—usually a few minutes.
**Pharmacist Tips**
-
Use only as directed and avoid daily or frequent use, as overuse may cause electrolyte imbalance or dependence.
-
Do not use if you have severe abdominal pain, suspected bowel obstruction, rectal bleeding, or kidney problems unless advised by a healthcare professional.
-
Results are typically rapid, often occurring within 1–5 minutes.
-
Seek medical care if no bowel movement occurs after use.
Product Selection Guide​
-
For Hard or Painful Stools: Use a stool softener (docusate) to reduce straining, especially if you have hemorrhoids or discomfort with bowel movements.
​

​
-
For Hard and Infrequent Stools: Use a combination product (senna + docusate) when stool is both dry and difficult to pass and a single treatment has not been effective.
​
-
For Long-Term Regulation: Use psyllium fiber daily to add bulk and softness to stool. Best suited for ongoing maintenance when taken consistently with adequate hydration.
​
-
For Gentle, Consistent Relief: Use polyethylene glycol (PEG, e.g., MiraLAX®) to draw water into the colon and increase stool frequency. Helpful for frequent or chronic constipation.
​
-
For Faster Relief: Use milk of magnesia occasionally when more rapid action is needed.
​
-
For Urgent Constipation: Use a Fleet® Saline Enema when other treatments have not worked. This option is for short-term or emergency use—not regular management.
​
Important:
Seek medical care if constipation is severe, persistent (longer than 2 weeks), or accompanied by severe abdominal pain, vomiting, blood in stool, or unexplained weight loss.
