Symproic (naldemedine) is a prescription opioid antagonist. More specifically, it's a peripherally acting mu-opioid receptor antagonist (PAMORA) that targets opioid receptors in the gut. It's a first-choice treatment option for opioid-induced constipation in adults. It comes as a tablet that's taken by mouth once per day with or without food. Side effects include stomach pain, diarrhea, and nausea. Symproic (naldemedine) is brand name only and not available as a generic.
People who take opioid medications for pain commonly experience constipation as a side effect. This is because opioid receptors are found in the brain and the gut. Opioid medications ease pain by affecting the receptors in the brain, but they cause constipation when they affect the receptors in the gut.
Symproic (naldemedine) is a peripherally acting mu-opioid receptor antagonist (PAMORA). This means that it blocks opioid receptors in the gut only, but not in the brain. As a result, Symproic (naldemedine) relieves constipation from opioid medications, without affecting their pain-relieving actions.
The following side effects may get better over time as your body gets used to the medication. Let your healthcare provider know immediately if you continue to experience these symptoms or if they worsen over time.
Contact your healthcare provider immediately if you experience any of the following.
Side effects that you should report to your care team as soon as possible:
Side effects that usually do not require medical attention (report these to your care team if they continue or are bothersome):
No, weight gain isn't a typical side effect of Symproic. Let your healthcare team know if you experience unexpected weight gain after you start Symproic. They can help figure out the cause and recommend tips to help you maintain a healthy body weight.
Studies show most people had a bowel movement within 24 hours of starting Symproic. It can take about a week to get the maximum benefit from the medication. Keep taking Symproic every day and follow up with your prescriber if you're concerned with how well the medication is working for you.
No. When Symproic was first FDA-approved, it was classified as a schedule II controlled substance because it can be derived from opium alkaloids. But after further review, the Drug Enforcement Administration (DEA) removed this classification because this medication is not an opioid pain medication. Instead, Symproic is an opioid antagonist that helps treat constipation from opioid medications, which are controlled substances.
No, Symproic and Relistor (methylnaltrexone) aren't the same, but they're similar. Both are peripherally acting mu-opioid receptor antagonist (PAMORA) used to treat constipation from opioids. They're taken by mouth once per day and have similar side effects (e.g., stomach pain, diarrhea, nausea). One difference is that Relistor (methylnaltrexone) is also available as an injection under the skin, while Symproic isn't. Treatment guidelines recommend both medications for the treatment of constipation due to opioids. Talk to your healthcare professional if you have more questions about the differences between both medications.
Though not common, it's possible for Symproic to cause opioid withdrawal symptoms, like sweating, chills, fever, and stomach pain. People who have medical conditions that affects the blood–brain barrier (BBB), such as stroke or brain injury, are at higher risk for this side effect. Contact your prescriber right away if you notice any withdrawal symptoms.
Symproic can technically be taken at any time of day. But you might consider taking it in the morning since it can make you go to the bathroom. Let your prescriber know if taking Symproic in the morning isn't possible for you to discuss the best time of day to take the medication.
No, there isn't a generic version of Symproic available yet.
Symproic (naldemedine) can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.
In some rare cases, people who've taken Symproic (naldemedine) reported having stomach or gut problems, including inflammation or a tear in the wall of the gut. This can be dangerous and require hospitalization. Before you start Symproic (naldemedine), let your prescriber know if you have a history of bowel or gut-related problems. Notify your healthcare team right away if you have severe stomach pain, stomach pain that doesn't go away, worsening stomach pain, chills, or fever.
Although rare, some people who took Symproic (naldemedine) experienced withdrawal symptoms, such as sweating, chills, diarrhea, stomach pain, anxiety, and irritability. In some rare cases, you might also get less pain relief from your opioid medication. People who have medical conditions that affects the blood–brain barrier (BBB), such as stroke or brain injury, are at higher risk for these side effects. Talk to your prescriber if you experience any withdrawal symptoms or if your pain medication isn't working as well anymore.
