Magnesium hydroxide for constipation

About magnesium hydroxide

Constipation is a common problem. It can mean either going to the toilet less often than usual to empty your bowels, or passing hard or painful stools. Constipation 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. Often, increasing the amount of fibre in your diet (such as by eating more fruit, vegetables, cereals and wholemeal bread) and drinking plenty of water each day can effectively prevent or relieve constipation. A laxative such as magnesium hydroxide can also be helpful, if used occasionally.

Magnesium hydroxide works by drawing fluid into your bowel, which makes your stools softer and easier to pass. It can be bought without a prescription at pharmacies and other retail outlets.

Before taking magnesium hydroxide

To make sure that this is the right treatment for you, ask a pharmacist or doctor for advice before you start taking magnesium hydroxide if:

• You are pregnant. This is because if you are expecting a baby, medicines should only be taken on the advice of a doctor.

• You have problems with the way your kidneys work, or problems with the way your liver works.

• You have severe tummy (abdominal) pain, cramping, or sickness (vomiting).

• You are taking any prescription medicines. This is because magnesium hydroxide can reduce the absorption of many medicines.

• Sie hatten schon einmal eine allergische Reaktion auf ein Arzneimittel.

How to take magnesium hydroxide

• Before you start taking the mixture, read the manufacturer's printed information attached to the pack. It will give you more information about magnesium hydroxide and how to take it.

• Shake the bottle well to make sure the medicine is evenly mixed before pouring out a dose. The dose for an adult is 30-45 ml (six to nine 5 ml spoonfuls). The dose for a child aged 3-12 years is 5-10 ml (one or two 5 ml spoonfuls), although magnesium hydroxide should only be given to a child on the advice of a healthcare professional. Swallow the dose with a glass of water or milk at bedtime. The water/milk helps the magnesium hydroxide to work so it is important that you drink a glassful. It is also especially important if you are elderly, or at risk of becoming lacking in fluid in the body (dehydrated) for any reason.

• Magnesium hydroxide is a laxative for occasional use only - do not take it for more than three consecutive days. It must not be taken to prevent constipation or to 'keep you regular'. If you are concerned about your bowel habit, please speak with your doctor for advice.

• Do not take magnesium hydroxide at the same time as any other medicines. This is because it can interfere with the way your body absorbs other medicines and may stop them from working properly. Try to leave at least two hours both before and after a dose of magnesium hydroxide before you take any other medicines.

Das Beste aus Ihrer Behandlung herausholen

• It is important for you to drink plenty while you are constipated. Adults should aim to drink at least two litres (about 8-10 cups) of fluid per day. Most sorts of drink will do but as a start, try just drinking a glass of water 3-4 times a day in addition to what you normally drink.

• Versuchen Sie, eine ausgewogene Ernährung mit ballaststoffreichen Lebensmitteln wie Vollkornbrot und -getreide, Obst und Gemüse, braunem Reis und Vollkornnudeln zu essen. Wenn Sie nicht an eine ballaststoffreiche Ernährung gewöhnt sind, sollten Sie die Menge an Ballaststoffen schrittweise erhöhen.

• Wenn Sie Ihren Körper aktiv halten, können Sie Ihr Verdauungssystem in Schwung halten, also versuchen Sie, sich regelmäßig zu bewegen.

• You may wish to include some foods in your diet that contain sorbitol. Sorbitol is a naturally occurring sugar. It is not digested very well and draws water into your bowel which has an effect of softening stools. Fruits (and their juices) that have a high sorbitol content include apples, apricots, gooseberries, grapes (and raisins), peaches, pears, plums, prunes, raspberries and strawberries.

• You can read more about how to prevent or treat constipation in the separate condition leaflets called Constipation (for adults) and Constipation in Children.

Can magnesium hydroxide cause problems?

Occasionally, people who have taken magnesium hydroxide have experienced digestive symptoms such as mild diarrhoea and stomach cramps. If either of these happens to you, stop taking it. Other side-effects are unlikely but if you do experience any other symptoms, speak with a doctor or pharmacist for further advice.
