Which constipation medication is best for me?

The constipation aids we sell are a mix of antispasmodic medication to help the muscles of your gut relax, herbal treatments that have a similar effect on your body to help you have easier bowel movements, and sachets of electrolytes and epsom salts to gently help your body stay hydrated and regulate its bowel movements.

Do you need a prescription?






No, but can also be prescribed




Occasional constipation is very common and can affect people of all ages. It can usually be treated at home with simple diet and lifestyle changes or medication available without prescription. Some people may suffer from chronic constipation—if this is the case for you, it may be worth speaking to your doctor about.

How do I know if I’m constipated?

Depending on your diet and lifestyle, you may be more prone to constipation. If you haven’t been able to pass stool for three or more days, it’s probably worth adding more fibre to your diet or taking medication to help your bowels.

You might also be constipated if your stools are very hard or if they are causing you discomfort or straining to pass them.

What causes constipation?

Sometimes there may be no obvious cause for constipation, and there are many different things that can cause it.

The most common causes of constipation include:

  • Not eating enough fibre
  • Not drinking enough fluids
  • Not moving around enough, being less active or spending long periods sitting or lying down
  • Ignoring the urge to use the toilet
  • Sudden changes in your diet or daily activities
  • A side effect of certain medicines
  • Stress, anxiety and depression

Constipation is also common during pregnancy and for 6 weeks after giving birth.

When should I talk to my doctor about constipation?

Usually you won’t need to talk to your GP about being constipated, but if any of the following apply to you then it might be beneficial to seek help:

  • If you are not improving with treatment (laxatives or diet/lifestyle changes)
  • If you have blood in your poo
  • If you are regularly constipated for a long time
  • If you feel very tired all the time
  • If you have lost weight very suddenly
