Because irritable bowel syndrome signs and symptoms may include diarrhea, constipation or a combination of both, the recommended prescriptions and over the counter medications for irritable bowel syndrome vary depending on the individual. For example, Zelnorm is used to treat IBS with constipation, but it should not be used by those who suffer from IBS with diarrhea.

Irritable bowel syndrome signs and symptoms typically include abdominal (stomach) pain that is relieved by a bowel movement. It is believed that the pain may be caused by muscle spasms, so anti-spasmodic medications for irritable bowel syndrome are sometimes prescribed. The idea being that reducing the muscle spasms or contractions may relieve the pain, relax the intestines and possibly prevent diarrhea. Anti-spasmodic medications, like most prescription drugs, are not intended for long term use, so a complete treatment program which includes dietary changes and other therapies may be recommended as well.

Anti-depressants are sometimes prescribed for IBS. Depression is not commonly one of the irritable bowel syndrome signs and symptoms, but studies have shown anti-depressants may block pain receptors in the brain. Most prescribed medications for irritable bowel syndrome target pain relief. Stress and anxiety sometimes accompany irritable bowel syndrome signs and symptoms and anti-depressants may help relieve these, as well as the pain.

Over the counter medications for irritable bowel syndrome with diarrhea include Kaopectate, Imodium and other anti-diarrhea products. But though they may be effective for slowing diarrhea, they will not help to relieve the other irritable bowel syndrome signs and symptoms. Herbal and botanical remedies may be effective for the relief and control of IBS with diarrhea or constipation, but there is no conclusive evidence that they work. There are only user testimonials. What works for one may not work for everyone and natural does not always mean safe. Herbs and botanicals should only be purchased from reliable companies. Doctor consultation is often recommended, but most doctors know very little about herbal and botanical treatment. A better source for information may be an herbalist or doctor of naturopathic medicine.

Irritable bowel syndrome signs and symptoms may include excessive gas, bloating or feeling that the stomach is swollen. If these symptoms are present, recommended over the counter medications for irritable bowel syndrome may include Gas-X or other anti-gas products. Herbs and botanicals designed to prevent or relieve gas are also available.

Irritable bowel syndrome signs and symptoms are very similar to the symptoms of other more serious conditions such as colitis and Crohn's disease. If you have some or many irritable bowel syndrome signs and symptoms, it is important to consult your doctor. A complete physical exam or other tests may be necessary to learn what is causing your pain. Your doctor can also help you decide if over the counter or prescription medications for irritable bowel syndrome or other therapies are right for you.
