Important information about Amitiza
The active ingredient in Amitiza is lubiprostone. This medication is a laxative and belongs to a class of medications known as chloride channel activators. Its mechanism of action involves turning on switches in your cells that tell more fluid to come into your intestines and gastrointestinal tract. This softens the stool, making it easier to have a bowel movement.
Follow all directions given to you by your doctor and read all documents provided, including the full Prescribing Information, FDA-Approved Product Labeling, Instructions for Use, and Medication Guide before using Amitiza. However, the following is a synopsis of the general guidelines for the use of Amitiza:
- Take this medication exactly as directed by your physician. It is typically taken by mouth twice daily.
- Swallow the capsule whole and do not crush, chew, break, or open it.
- If you miss a dose, take it as soon as you can. If it is almost time for your next dose, take only that dose.
The most common side effects of Amitiza include:
- Bloating.
- Diarrhea.
