1. What Rizmoic is and what it is used for

Rizmoic contains the active substance naldemedine.

It is a medicine used in adults to treat constipation caused by pain medicines, called opioids (e.g morphine, oxycodone, fentanyl, tramadol, codeine, hydromorphone, methadone).

Your opioid pain medicine may cause the following symptoms:

  • reduction in how often you pass stools
  • hard stools
  • stomach ache
  • pain in the rectum when pushing hard stools out
  • a feeling that the bowel is still not empty after passing stools.

Rizmoic can be used in patients using an opioid medicine for cancer pain or long term non-cancer pain after they have previously been treated with a laxative.

2. What you need to know before you take Rizmoic
Do not take Rizmoic:
  • if you are allergic to naldemedine or any of the other ingredients of this medicine (listed in section 6).
  • if your bowel is blocked or perforated, or if there is a high risk of your bowel becoming blocked, as a blockage may cause a hole to develop in the bowel wall.

Do not take this medicine if any of the above applies to you. If you are not sure, talk to your doctor or pharmacist before taking Rizmoic.

Warnings and precautions

Talk to your doctor or pharmacist before taking Rizmoic:

  • if you suffer from a disease which may affect your bowel wall such as:
    • a stomach ulcer;
    • an enlarged colon due to a condition known as Ogilvie’s syndrome;
    • diverticulitis (an illness where your gut is inflamed);
    • cancer of the bowel or peritoneum.
      The peritoneum is the lining of your gut area.
    • a disease causing severe inflammation of the digestive tract such as Crohn’s disease .
  • if you have cancer of the brain or central nervous system, multiple sclerosis, or Alzheimer’s disease. If you have these conditions and develop opioid withdrawal symptoms (see section 4) or if the opioid medicine no longer controls your pain, contact your doctor immediately.
  • if you have had a heart attack within the last 3 months or if you have other severe problems with your heart which cause daily symptoms
  • if you have severe liver disease such as alcoholic liver disease, viral liver infection or impaired liver function.
  • if you are taking certain medicines such as itraconazole to treat fungal infections, or an antibiotic called rifampicin to treat tuberculosis and other infections. See ‘Other medicines and Rizmoic’.

If any of the above apply to you, or you are not sure, talk to your doctor or pharmacist before taking Rizmoic.

Talk to your doctor or pharmacist immediately whilst taking Rizmoic:

  • if you develop severe, lasting or worsening stomach pain as this could be a symptom of developing a hole in your bowel wall and can be life-threatening.
    Speak to your doctor immediately and stop taking Rizmoic.
  • if you suffer from symptoms of opioid withdrawal syndrome (see section 4 Possible side effects) which can develop within minutes to several days after taking a medicine such as Rizmoic. Stop taking Rizmoic and contact your doctor if you develop opioid withdrawal symptoms.
  • if you have severe diarrhoea or stomach ache, tell your doctor, so that the doctor can monitor you and treat you with rehydration and appropriate medicines if needed.

If you stop taking your opioid medicine

If you take more Rizmoic than you should

If you have taken more Rizmoic than you should, talk to your doctor or go to the hospital. You will be monitored for opioid withdrawal symptoms (see section 2, under ‘Warnings and Precautions’, and section 4).
