What is Relistor 150 mg?
Relistor 150 mg is a brand of methylnaltrexone (an opioid receptor antagonist) used to treat certain forms of opioid-induced constipation. It is designed to counter constipation caused by opioid pain medicines without reversing the pain relief.
What is Relistor 150 mg used for?
Relistor is used when constipation is caused by opioids, including:
- Opioid-induced constipation in people with advanced illness who are receiving opioid therapy.
- Opioid-induced constipation in adults (and, depending on local prescribing information, may include certain pediatric indications via specific formulations).
How does Relistor 150 mg work?
Methylnaltrexone blocks opioid effects in the gut by antagonizing opioid receptors in the gastrointestinal tract. This helps restore bowel function while preserving the analgesic effect of opioids.
What doses are typical for Relistor 150 mg?
The “150 mg” strength is the tablet dose commonly associated with adult use. The exact regimen depends on patient factors (including opioid regimen and constipation severity) and should follow the specific prescribing information.
What side effects do people report with Relistor?
Common side effects can include gastrointestinal symptoms such as:
- Abdominal pain or discomfort
- Nausea

As with any constipation treatment, patients should seek medical advice if symptoms worsen or if they develop severe abdominal pain.

If you tell me what you need (for example, “dose for adults,” “how fast it works,” “side effects,” “who can’t take it,” or “generic/patent status”), I can narrow the answer to that exact question.
