Medicines

Your doctor may recommend medicine to relieve your IBS symptoms.

To treat IBS with diarrhea, your doctor may recommend

loperamide
rifaximin (Xifaxan), anantibiotic
eluxadoline (Viberzi)
alosetron (Lotronex), which is prescribed only to women and is prescribed with special warnings and precautions

To treat IBS with constipation, your doctor may recommend

fiber supplements, when increasing fiber in your diet doesn’t help
laxatives
lubiprostone (Amitiza)
linaclotide (Linzess)
plecanatide (Trulance)

Other medicines may help treat pain in your abdomen, including

antispasmodics
antidepressants, such as low doses of tricyclic antidepressants and selective serotonin reuptake inhibitors
coated peppermint oil capsules

Follow your doctor’s instructions when you use medicine to treat IBS. Talk with your doctor about possible side effects and what to do if you have them.

Probiotics

Your doctor may also recommend probiotics. Probiotics are live microorganisms, most often bacteria, that are similar to microorganisms you normally have in your digestive tract. Researchers are still studying the use of probiotics to treat IBS.

To be safe, talk with your doctor before using probiotics or any other complementary or alternative medicines or practices. If your doctor recommends probiotics, talk with him or her about how much probiotics you should take and for how long.

Mental health therapies

Your doctor may recommend mental health therapies to help improve your IBS symptoms. Therapies used to treat IBS include

cognitive behavioral therapy, which focuses on helping you change thought and behavior patterns to improve IBS symptoms
gut-directed hypnotherapy, in which a therapist uses hypnosis—a trance-like state in which you are relaxed or focused—to help improve your IBS symptoms
relaxation training, which can help you relax your muscles or reduce stress
