Best prescription medications to treat IBS

Commonly Prescribed IBS Medications

Several classes of prescription medications are commonly used to treat IBS, depending on the main symptoms and IBS subtype.

For people with abdominal pain and discomfort as their main symptoms, antispasmodics may be prescribed. These medications, such as dicyclomine (Bentyl) and hyoscyamine (Levsin), work by relaxing the muscles in the gut, helping to reduce abdominal pain and cramping. 4,5

For those with diarrhea-predominant IBS (IBS-D), antidiarrheal medications like loperamide (Imodium) can help control loose stools and reduce how often you have a bowel movement. 6 Loperamide works by slowing down the movement of fluids through the intestines, allowing more water to be absorbed back into the body.

On the other hand, people with constipation-predominant IBS (IBS-C) may benefit from laxatives or medications that promote bowel movements. Lubiprostone (Amitiza) and linaclotide (Linzess) are two medications that work by increasing fluid secretion in the intestines, making stools softer and easier to pass. 7,8

Antidepressants, particularly tricyclic antidepressants (TCAs) and selective serotonin reuptake inhibitors (SSRIs), can also help manage IBS symptoms. 9,10 These medications work by modulating pain signals in the gut and changing gut motility, even at lower doses than those used for treating depression.

In some cases, antibiotics like rifaximin (Xifaxan) may be prescribed to treat IBS-D. Rifaximin is a non-absorbable antibiotic that works by targeting bacteria in the gut, which may play a role in IBS symptoms. 11

Natural Remedies for IBS Relief

In addition to prescription medications, several natural remedies can help you manage IBS symptoms. Some of these are:

• Peppermint oil: This oil contains menthol, which can relax the muscles in the gut and reduce abdominal pain. 12,13 Peppermint oil capsules, when taken as directed, can provide relief for some people with IBS.
• Probiotics: Probiotics are beneficial bacteria that help maintain a healthy gut microbiome. 14,15 Certain probiotic strains, such as Bifidobacterium and Lactobacillus, have been found to improve IBS symptoms, including bloating, abdominal pain, and bowel habits.
• Herbal remedies: Remedies such as ginger and chamomile have also been traditionally used to alleviate digestive issues. Ginger has anti-inflammatory properties and can help reduce nausea and bloating, while chamomile has a calming effect on the digestive system. 16,17
• Fiber supplements: Supplements such as psyllium husk or methylcellulose can help regulate bowel movements and alleviate constipation in some people with IBS-C. 18 However, it is important to introduce fiber gradually and drink plenty of water to prevent discomfort and bloating.

Lifestyle Changes to Manage IBS Symptoms

Making lifestyle changes is an important part of managing IBS symptoms. Some of these changes include:

• Dietary changes: Following a low-FODMAP diet can help identify and eliminate trigger foods that make IBS symptoms worse. 19,20 FODMAPs (fermentable oligosaccharides, disaccharides, monosaccharides, and polyols) are short-chain carbohydrates that are poorly absorbed in the gut, leading to gas, bloating, and abdominal discomfort in some people with IBS.
• Stress management techniques: Techniques such as meditation, yoga, and deep breathing exercises, can also help reduce IBS symptoms. 21,22 Stress is a significant trigger for IBS flare-ups, and learning to manage stress effectively can help improve overall gut health and well-being.
• Regular exercise: Getting physical activity helps regulate bowel movements, reduces stress, and improves mood. Aim for at least 30 minutes of moderate exercise, such as brisk walking or cycling, most days of the week.
• Adequate sleep and hydration: Lack of sleep can exacerbate digestive issues and increase stress levels, while dehydration can worsen constipation. Aim for 7-9 hours of quality sleep per night and drink plenty of water throughout the day.

Potential Side Effects of IBS Medications

As with any medication, IBS treatments can cause potential side effects. Antispasmodics may cause dry mouth, blurred vision, constipation, and difficulty urinating. 31 Antidiarrheal medications like loperamide can cause abdominal pain, bloating, and nausea. 32

Laxatives and medications that promote bowel movements may cause diarrhea, abdominal pain, and bloating, especially when first starting treatment. 33 Antidepressants can cause side effects such as dry mouth, drowsiness, and weight gain, although these may be less common at the lower doses used for IBS treatment. 34

If side effects are severe or persistent, consult with a healthcare provider. They may recommend adjusting the medication dose, switching to a different medication, or exploring alternative treatment options. In some cases, lifestyle changes and natural remedies may be recommended to help manage side effects.

Conclusion

IBS is a complex disorder that requires a personalized approach to treatment. Prescription medications, including antispasmodics, antidiarrheals, laxatives, and antidepressants, can be effective in managing IBS symptoms. However, the choice of medication depends on the main symptoms, IBS subtype, and personal response to treatment.

Natural remedies, such as peppermint oil, probiotics, and herbal supplements, may also provide relief for some people with IBS. Lifestyle changes, including dietary changes, stress management techniques, regular exercise, and adequate sleep and hydration, can all help you manage your IBS.

Working closely with a healthcare provider is important to developing a personalized treatment plan that addresses specific needs and preferences. With the right combination of medications, natural remedies, and lifestyle changes, people with IBS can effectively manage their symptoms and improve their quality of life.
