Senna for constipation

About senna

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.

You could be recommended senna as a laxative to help relieve constipation if you cannot increase the fibre in your diet, or if this is insufficient. Senna works by encouraging the muscles in your bowel to move stools through your body. This helps you to go to the toilet. It usually has an effect within 8-12 hours. It is available to buy without a prescription at pharmacies and other retail outlets.

Before taking senna

To make sure that this is the right treatment for you, before you start taking senna it is important that you speak with your doctor or a pharmacist if:

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

• It is intended for a child under 12 years old. Laxatives should only be given to children on the advice of a doctor, or a healthcare professional experienced in the management of constipation in children.

• You are so constipated that you think you may have a blockage.

• Está tomando o utiliza otros medicamentos. Esto incluye cualquier medicamento que esté tomando y que pueda adquirirse sin receta, así como las hierbas medicinales y los medicamentos complementarios.

• Ha tenido alguna vez una reacción alérgica a un medicamento.

How to take senna

• Before taking senna, read the manufacturer's printed information leaflet from the pack. It will give you more information about the medicine and will provide you with a full list of the side-effects which you could experience.

• The usual adult dose is two to four 7.5 mg tablets, or two to four 5 ml spoonfuls (10-20 ml) of liquid medicine once a day. Take senna in the evening. It should only be used for a few days - this is because your bowel can start to rely on this type of laxative to make it work rather than working on its own. If you are still constipated after taking senna for three days, you should make an appointment to speak with your doctor.

• If a doctor or healthcare professional has recommended senna for your child, check the label on the pack carefully to make sure that you give the correct dose for the age of your child.

• 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.

• Intente seguir una dieta equilibrada que contenga alimentos ricos en fibra, como panes y cereales integrales, fruta y verdura, arroz integral y pasta integral. Si no está acostumbrado a una dieta rica en fibra, puede ser mejor que aumente la cantidad de fibra que ingiere de forma gradual.

• Mantener el cuerpo activo le ayudará a mantener el sistema digestivo en movimiento, así que intente hacer algo de ejercicio diario con regularidad.

• 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) which 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.
