The Effectiveness of Colace vs. Senokot
Colace
Colace is a stool softener, so it is not as effective in relieving constipation as a laxative would be. Colace can take up to three days to soften the stool for a bowel movement to take place unless you are using the suppository. Colace is considered safe to be taken long-term with the guidance of a doctor.
Colace Contraindications
Colace should not be taken in cases of:
- Hypersensitivity
- Intestinal obstruction, symptoms of appendicitis or acute abdominal pain, fecal impaction
- Concomitant use of mineral oil
- Nausea or vomiting
Senokot
Senokot encourages the muscles in the intestines to move so that a stool moves through the body. This process happens faster than with just a standard stool softener. It is recommended to take Senokot before bed, so you have a bowel movement in the morning. Senokot is not recommended for long-term use because your bowel will become dependent on the medication.
Senokot Contraindications Senokot should not be taken in cases of:
- Hypersensitivity
- Gastrointestinal obstruction or perforation
- Ulcerative colitis
- Symptoms of appendicitis or acute surgical abdomen
- Crohn's disease
- Fecal impaction
- GI or rectal bleeding
The Side Effects of Colace vs. Senokot
Colace
- Abdominal pain
- Diarrhea
- Cramping
- Irritated throat (with liquid form)
- Irritated rectum (with suppository)
Senokot
- Abdominal pain
- Cramping
- Nausea
- Diarrhea
- Weakness
The Difference Between Colace and Senna
Stool softeners like Colace are generally safer than a laxative like Senokot because they are used less frequently and have less chance of causing dependence. However, Colace is not as effective as Senokot in relieving the symptoms of constipation. Many people find that a combination of a Colace and senna provides the best benefit.
Pricing Comparison
Colace vs. Senokot: Which Product Is Better?
Both Colace and Senokot have benefits. If you are looking for relief for hard, dry stools or occasional constipation and aren't in a hurry to have a bowel movement, then Colace will be more suited to you. If you are looking for a more natural alternative that provides overnight relief from constipation, Senokot would be the better option.
Overall, deciding which constipation relief product to choose comes down to personal preference.
