Constipation Medications: OTC and Prescription Options

Tricyclic agents such as amitriptyline and imipramine were initially prescribed to IBS patients with significant depression. Today, they are frequently used to treat patients with severe or refractory IBS symptoms and may have analgesic and neuromodulatory benefits in addition to their psychotropic vicks on cotton ball in ear effects. In one trial, nearly 70 percent of patients receiving 10 mg of amitriptyline experienced a complete loss of IBS symptoms compared with 28 percent of those on placebo. Most OTC laxatives are safe to use during pregnancy and breastfeeding, but you should talk to your doctor before using.

The benzodiazepine receptor modulator dextofisopam binds to benzodiazepine receptors in the brain, not the GI tract, without a sedating effect. In animal studies, it exhibited the potential to reduce colonic motility and visceral sensitivity in response to stress. Further studies are needed to determine the mechanism of action, safety and efficacy in humans. In two placebo-controlled, parallel-group studies of 1,000 patients with IBS-D, this selective 5-HT3 antagonist increased self-reported global assessment of relief of IBS symptoms. Constipation occurred in roughly 5 percent of participants — less than the rate observed with alosetron.

Side effects, drug interactions, dosage, and pregnancy safety information should be reviewed prior to taking this medication. Treatment for IBS includes diet changes, medications, and other lifestyle changes to manage symptoms. Despite their widespread use, traditional treatments for IBS-C are of limited effectiveness in improving IBS symptoms, such as bulking agents, stool softeners, laxatives and antispasmodics. Linaclotide is a selective agonist of GC-C, which is selectively expressed in the brush border membranes of the intestinal mucosa from the duodenum to the rectum.

“You want to give routine laxatives a chance because many times you can treat the constipation without going to an opioid antagonist,” Wald says.
