6. Contents of the pack and other information
Constella contains the active substance linaclotide. It is used to treat the symptoms of moderate to severe irritable bowel syndrome (often just called “IBS”) with constipation in adult patients.
IBS is a common gut disorder. The main symptoms of IBS with constipation include:
These symptoms may vary from person to person.
Constella acts locally in your gut, helping you to feel less pain and less bloated, and to restore the normal functioning of your bowels. It is not absorbed into the body, but attaches to receptor called guanylate cyclase C on the surface of your gut. By attaching to this receptor, it blocks the sensation of pain and allows liquid to enter from the body into the gut, thereby loosening the stools and increasing your bowel movements.
Your doctor has given this medicine to you after excluding other diseases, especially of your bowels and concluding that you suffer from IBS with constipation. Because these other diseases may have the same symptoms as IBS, it is important that you report any change or irregularity in symptoms to your doctor promptly.
If you experience severe or prolonged diarrhoea (passing of frequent watery stools for 7 days or more), stop taking Constella and contact your doctor (see section 4). Make sure you drink plenty of fluids to replace the water and electrolytes like potassium lost from the diarrhoea.
If you have severe stomach symptoms which continue or get worse, stop taking Constella and contact your doctor immediately because these could be symptoms of a hole developing in the bowel wall (gastrointestinal perforation). See section 4.
Talk to your doctor if you experience bleeding from the bowel or rectum.
Take special care if you are older than 65 years, as there is a higher risk you experience diarrhoea.
Take also special care if you have severe or prolonged diarrhoea and an additional disease, such as high blood pressure, previous disease of the heart and blood vessels (e.g. such as previous heart attacks) or diabetes.
Talk to your doctor if you suffer from inflammatory diseases of the guts such as Crohn’s disease or ulcerative colitis as Constella is not recommended in these patients.
Do not give this medicine to children and adolescents under the age of 18 years because the safety and efficacy of Constella in this age group has not been established.
Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines:
Constella produces more frequent bowel movements and diarrhoea (looser stools) when it is taken with food than when it is taken on an empty stomach (see section 3).
Limited information is available on the effects of Constella in pregnant and breast-feeding women.
Do not take this medicine if you are pregnant, think you may be pregnant or are planning to have a baby, unless your doctor advises you to do so.
In a milk-only lactation study in seven lactating women, who were already taking linaclotide therapeutically, neither linaclotide nor its active metabolite were detected in the milk. Therefore breastfeeding is not expected to result in exposure of the infant to linaclotide and Constella can be used during breast-feeding.
Constella will not affect your ability to drive or use machines
Always take this medicine exactly as your doctor has told you. Check with your doctor or pharmacist if you are not sure.
The recommended dose is one capsule (i.e. 290 micrograms of linaclotide) taken orally once a day. The capsule should be taken at least 30 minutes before a meal.
If you have not experienced improvement in your symptoms after 4 weeks of treatment, you should contact your doctor.
The most likely effect of taking too much Constella is diarrhoea. Contact your doctor or pharmacist if you have taken too much of this medicine.
Do not take a double dose to make up for a forgotten dose. Just take the next dose at the scheduled time and continue as normal.
It is preferable to discuss stopping treatment with your doctor before actually doing so. However, treatment with Constella can be safely stopped at any time.
If you have any further questions on the use of this medicine, ask your doctor or pharmacist.
