Buy Linzess (Linaclotide) Online

Linzess is affordable and easy to buy with Canada Drug Warehouse. You can order your prescription medications online or call us 7 days a week and get your Linzess delivered to your door for the fraction of the cost you usually pay.

What is Linzess?

Linzess (linaclotide) is a medication used to treat chronic constipation or chronic irritable bowel syndrome (IBS) for adults who have constipation as the main symptom. Linzess works by increasing the secretion of chloride and water in the intestines which softens stools and stimulates bowel movements.

Always read the patient information and instructions carefully before using this medication.

  • Take Linzess orally on an empty stomach. Linzess is typically taken once a day at least 30 minutes before your first meal of the day.
  • Swallow Linzess capsules whole without breaking or chewing them.
  • If you have problems swallowing the capsule, you can open the capsule and mix the contents with a teaspoon of apple sauce and swallow without chewing. Alternatively you can empty a capsule into 30ml of water, swirl the mixture for 20 seconds before drinking. Add another 30ml of water into the cup and swirl that for 20 seconds and drink to make sure you get the full dose.
  • Your Linzess dosage is based on your medical condition and your response to treatment. Do not change your dosage or the frequency you take this medication unless advised by a doctor.
  • Linzess is most effective when it is taken regularly. Try to take this medication at the same time each day. Tell your doctor if your condition does not improve or worsens.


Make sure to tell your doctor and pharmacist:

  • If you have any drug allergies.
  • Which other prescription and non-prescription medications you currently take.
  • Your medical history especially of stomach or intestinal blockage.
  • If you are breast feeding.

Also be aware that:

  • This medication should only be taken when clearly needed during pregnancy.

Linzess Side Effects

Common Linzess side effects may include but are not limited to:

  • Diarrhea, stomach pain or gas.
  • Bloating or feeling full.

Contact your doctor if you experience any of the following side effects of Linzess:

  • Severe or ongoing diarrhea.
  • Diarrhea alongside dizziness or lightheadedness.
  • Severe stomach pain.
  • Black, bloody or tarry stools.
  • Signs of an electrolyte imbalance such as feeling unsteady, irregular heartbeats, fluttering in your chest, leg cramps, mood changes, confusion, muscle weakness, limp feeling or increased urination or thirst.
  • Signs of an allergic reaction such as hives, difficulty breathing or a swelling of your face, lips or throat.


Q: What else is Linzess called?

A: Linzess is also known as Constella. Constella is not a generic alternative but the same brand name medication with a different name internationally.

Q: What should I do if I miss a dose of Linzess?

A: Skip your missed dose and take the medicine at the next scheduled time. Do not take extra medication to make up for a missed dose.
