The research suggests that Amitiza is slightly better than a placebo in reducing the symptoms of constipation. Amitiza has been shown to:
- Increase stool frequency
- Produce more consistent, well-formed stools
- Reduce straining and incomplete bowel evacuation
- Reduce abdominal pain and discomfort
Many gastroenterologists use lubiprostone in limited settings, as there are many alternative treatment choices.
Amitiza is usually well-tolerated and serious side effects are rare. The following side effects have been reported:
- Nausea
- Diarrhea
- Headache
- Abdominal pain
- Abdominal distension
Nausea associated with Amitiza is not a rare event: It's estimated that 19 to 29% of Amitiza users experience nausea. In order to reduce the risk of nausea, it is recommended that you take the medication with food. To find out what type of experiences real people have had with with Amitiza, see:
