What Exactly is Naldemedine?
Simply put, Naldemedine is a prescription tablet used to treat constipation caused by opioid pain medicines. When you take strong pain relievers, they relieve your pain but also slow down the movement of your gut.
Think of your gut like a highway where traffic has suddenly slowed down to a crawl. This slowdown is what causes hard, difficult stools and uncomfortable constipation. Naldemedine steps in to fix this specific traffic jam.
The medicine travels directly to your gut and blocks the slowing effects of the pain killer. It tells your gut muscles to relax and start working normally again. The best part is that it does this without blocking the pain relief working in the rest of your body.
Important Note: This is not a treatment for ordinary, everyday constipation. It is strictly meant for constipation caused by opioid pain medicines.
