Contents of the pack
What Constella is used for
Constella contains the active substance linaclotida. It is used to treat the symptoms of irritable bowel syndrome with constipation (often referred to as IBS-C) of moderate to severe intensity in adult patients.
IBS is a common intestinal disorder. The main symptoms of IBS-C are:
These symptoms can vary from person to person.
How Constella works
Constella acts locally in the intestine, relieving pain and bloating and restoring normal bowel function. It is not absorbed by the body, but binds to a receptor on the surface of the intestine, called guanylate cyclase C. By binding to this receptor, it blocks the sensation of pain and allows fluid to pass from the body into the intestine, softening the stools and increasing bowel movements.
Do not take Constella
Warnings and precautions
Your doctor has given you this medicine after ruling out other diseases, especially of your intestines, and concluding that you have IBS-C. Since these other diseases can have the same symptoms as IBS, it is important that you inform your doctor immediately of any change or irregularity in your symptoms.
If you experience severe or prolonged diarrhea (frequent passage of liquid stools for 7 days or more), stop treatment with Constella and consult your doctor (see section 4); do not forget to drink plenty of fluids to replace the water and electrolytes, such as potassium, lost with diarrhea.
If you have severe stomach symptoms that persist or worsen, stop treatment with Constella and contact your doctor immediately, as they could be symptoms of a hole in the wall of the intestine (gastrointestinal perforation). See section 4.
Consult your doctor if you experience intestinal or rectal bleeding.
Take special precautions if you are over 65 years old, as you have a higher risk of experiencing diarrhea.
Also, take special precautions if you experience severe or prolonged diarrhea and have an additional disease, such as high blood pressure, a previous heart or blood vessel disease (e.g., previous heart attacks), or diabetes.
Consult your doctor if you have inflammatory bowel diseases such as Crohn's disease or ulcerative colitis, as Constella is not recommended in these patients.
Children and adolescents
Do not give this medicine to children or adolescents under 18 years old, as the safety and efficacy of Constella in this age group have not been established.
Other medicines and Constella
Tell your doctor or pharmacist if you are taking, have recently taken, or might take any other medicines:
Taking Constella with food
Constella increases the frequency of bowel movements and causes diarrhea (looser stools) to a greater extent when taken with food than when taken on an empty stomach (see section 3).
Pregnancy and breastfeeding
There is limited information on the effects of Constella in pregnant or breastfeeding women.
Do not take this medicine if you are pregnant, think you may be pregnant, or are planning to become pregnant, unless your doctor advises you to do so.
In a lactation study conducted in seven breastfeeding women who were already receiving treatment with linaclotida, no linaclotida or its active metabolite was detected in breast milk. Therefore, it is not expected that breastfeeding will cause exposure of the infant to linaclotida, and Constella can be used during breastfeeding.
Driving and using machines
Constella will not affect your ability to drive or use machines.
Follow the instructions for administration of this medicine exactly as told by your doctor. If you are unsure, consult your doctor or pharmacist again.
The recommended dose is one capsule (i.e., 290 micrograms of linaclotida) orally once daily. The capsule should be taken at least 30 minutes before a meal.
If you have not experienced improvement in your symptoms after 4 weeksof treatment, consult your doctor.
If you take more Constella than you should
The most likely effect of taking too much Constella is diarrhea. Contact your doctor or pharmacist if you have taken too much of this medicine.
If you forget to take Constella
Do not take a double dose to make up for forgotten doses. Simply take the next dose at the scheduled time and continue with the treatment as usual.
If you stop taking Constella
Before stopping treatment, it is recommended that you consult your doctor; however, you can stop taking Constella at any time with complete safety.
If you have any further questions on the use of this medicine, ask your doctor or pharmacist.
