Macrogoles para el estreñimiento o la limpieza intestinal

About macrogols

Macrogols belong to a group of medicines known as osmotic laxatives. They are substances which are used medically to relieve constipation or to clear the bowel before some clinical procedures. They are sometimes called polyethylene glycols. Macrogols are identified by a number which represents their molecular weight so, for example, the macrogol used to relieve constipation is called macrogol '3350'.

Constipation is a common problem which can be caused by a number of things. Not eating enough fibre or not drinking enough fluid can cause constipation. Some conditions (such as pregnancy) can cause constipation, as can a lack of exercise or movement (such as being ill in bed) and some medicines. Macrogols relieve constipation by drawing water into your bowel to soften your stools, making them easier to pass.

Bowel cleansing solutions also contain macrogol '3350' although they are not treatments for constipation. They are used to ensure that the bowel is free of solid contents before a bowel examination or surgical procedure.

Before taking macrogols

Some medicines are not suitable for people with certain conditions, and sometimes a medicine may only be used if extra care is taken. For these reasons, before you start the treatment it is important that your doctor or pharmacist knows:

• Si estás embarazada o amamantando.

• If you have any bowel problems other than constipation, such as Crohn's disease, ulcerative colitis or toxic megacolon.

• Si tienes una afección cardíaca.

• Si alguna vez has tenido una reacción alérgica a un medicamento.

• If you use starch-based food-thickeners to help with difficulty swallowing.

• Si está tomando otros medicamentos. Esto incluye cualquier medicamento que esté tomando y que esté disponible para comprar sin receta, así como medicamentos herbales y complementarios.

• If the treatment is intended for a child. This is because laxatives should solo be given to children on the advice of a doctor or healthcare professional.

How to take macrogols

Before starting the treatment, read the manufacturer's printed information leaflet from inside the pack. It will tell you how to prepare your dose and how long the solution can be kept for after preparation. Once mixed with water, the solution should be kept in the fridge. Do not use any solution remaining after the time recommended in the manufacturer's instructions.

If taking for constipation (brands CosmoCol®, Movicol®, Laxido®, Molaxole®)

• Your doctor will tell you how many sachets to take for each dose. A daily dose can range from 1-2 sachets daily, up to a maximum of 8 sachets daily. Unless the directions say otherwise, stir the contents of each sachet into half a glass of water (100-125 ml) before taking.

If taking for bowel cleansing (brands Klean-Prep®, Moviprep®)

• You will be given written instructions from the clinic that will tell you how many sachets to make up into a solution, and when you should start to drink it. It is important that you follow the directions carefully.

• You will also be given written instructions about what food or drink you can, or cannot, have until after the procedure is completed. Typically, the advice is to not eat any solid food from about two hours before you start drinking the solution. Again, it is important that you carefully follow the directions you are given.

• The treatment can interfere with the absorption of medicines taken at the same time. If you take medication regularly, please ask your doctor about when to take your other medicines.
