RELISTOR is a prescription medication primarily used to treat opioid-induced constipation (OIC) in adults. Opioids, commonly prescribed for pain relief, often have the side effect of significantly slowing down the digestive system, leading to constipation. RELISTOR works by blocking the effects of opioids on the gut without affecting their pain-relieving properties on the brain. This action helps to restore normal bowel movements. It is available in both subcutaneous injection and oral tablet forms, offering flexibility in administration based on patient needs and preferences. The use of RELISTOR can provide significant relief for individuals suffering from OIC, improving their quality of life while continuing necessary pain management.
