What is Relistor 150 mg, and what is it used for?
Relistor 150 mg tablets contain methylnaltrexone bromide. It is used to treat certain types of constipation caused by opioids, typically when opioid medicines are needed but constipation has not responded adequately to standard laxatives.
How does Relistor work?
Relistor is an opioid receptor antagonist that targets opioid receptors in the gut. It helps reduce opioid-related constipation without reversing pain relief in the brain to the same extent as older, broader opioid-blocking drugs.
How do you take a 150 mg tablet (and who should avoid it)?
The dose depends on the patient’s situation and prescribing information. Patients are usually advised not to use it in ways that conflict with the label instructions, and dosing can be affected by kidney problems, since methylnaltrexone is cleared from the body through the kidneys.
What side effects are patients most likely to notice?
Common side effects can include gastrointestinal effects (such as abdominal pain, nausea, diarrhea) given the medicine’s action in the digestive tract. If severe symptoms occur (for example, significant or worsening abdominal pain), patients should seek urgent medical advice.
Is Relistor the only option for opioid-induced constipation?
No. There are multiple treatments for opioid-induced constipation, including other prescription options (often with different mechanisms) and non-drug measures. Choice depends on factors like prior laxative response, kidney function, and individual risk factors.
