What is the usual lubiprostone (Amitiza) dosage for constipation?
Lubiprostone dosing depends on the condition being treated and the patient’s age.
For adults treated for chronic idiopathic constipation or IBS-C, the standard regimen is 24 mcg taken by mouth twice daily with food.
What dose is used for IBS with constipation (IBS-C)?
For IBS-C, the usual lubiprostone dose is 8 mcg (by mouth) twice daily. Some prescribing may also use 24 mcg twice daily based on the indication and tolerability, but the most common labeled IBS-C starting/standard dose is 8 mcg twice daily.
How should lubiprostone be taken (with food vs empty stomach)?
Lubiprostone is taken by mouth with food. Taking it with food helps reduce the risk of nausea, which is one of the most common side effects.
Are there any dose adjustments or special instructions?
Lubiprostone dosing can be adjusted based on tolerability (especially if nausea occurs). If side effects are problematic, clinicians may reduce the dose or change the dosing schedule.
What if a dose is missed?
If you miss a dose, take it when you remember unless it’s close to the next scheduled dose. Do not take two doses at once.
What side effects do people commonly report at these doses?
Common side effects include nausea and diarrhea. Report severe or persistent symptoms to a clinician, especially dehydration from diarrhea.
