What is Fybogel Lemon?

Fybogel Lemon contains sachets of granules which are used to make up a lemon flavoured drink that you can take to relieve constipation. It helps to ease constipation naturally, making your poo easier to pass and letting you go to the toilet comfortably. This makes it ideal for those who have piles that are making their constipation worse and for those who are pregnant. If you’re looking for a natural way to relieve constipation, Fybogel is a tasty way to get things moving again.

Why am I constipated?

Constipation is a very common problem, you’ll probably experience it at least once in your lifetime and there are lots of reasons why it may happen to you. When you have constipation you’ll find that you aren’t able to poo for a few days at a time, and if you do poo it may be larger, harder, or lumpier than usual, making it more difficult to pass. Some of the most common causes of constipation include:

  • Not getting enough fibre in your diet

  • Not drinking enough fluids

  • A change in your diet or general routine

  • Being inactive or not exercising

  • Stress or anxiety

  • Some medications which can cause constipation, e.g. codeine, morphine

  • Some medical conditions

  • Pregnancy

  • Ignoring the urge to poo when you need to

Are piles (haemorrhoids) and constipation related?

Haemorrhoids are small lumps which can appear in and around your back passage. Some people may not notice that they have piles, but they can be itchy or sore and can make it more difficult for you to poo. The problem with this is that straining or pushing too hard when you have a poo may be the cause of your piles in the first place, so by making it more difficult for you to poo your piles just make the problem worse in an itchy, irritating cycle.

How will Fybogel Lemon relieve my constipation?

Fybogel Lemon contains an active ingredient called ispaghula husk, which can help to relieve your constipation by increasing the amount of fibre in your diet. This works naturally with your digestive system, making it easier to pass your poo without feelings of discomfort or urgency. This makes Fybogel not only ideal for those who are constipated, but can also help people with piles, as passing your poo more easily and without straining can help to reduce haemorrhoids.

Can I take this laxative when I’m pregnant?

You can take Fybogel Lemon if you’re pregnant or breastfeeding. However, you should speak to your doctor or pharmacist before taking this or any other medication at this time.

Can I take this product if I’m taking other medication?

If you’re taking any other medication you should speak to your doctor or pharmacist before taking Fybogel. This especially applies if you are already taking:

  • Other medications which cause constipation, e.g. codeine, morphine

  • Insulin

  • Medicines for thyroid problems

If a medical professional tells you that you can take this product with your regular medication, you should leave at least a 30 minute gap between taking your medication and drinking this product.

How to make up Fybogel sachets

Fybogel Lemon comes in sachets of granules which are used to make a drink. To make up the drink, start by filling a glass with 240ml of cold water, then add the amount of Fybogel granules you need. Stir the solution well so the granules dissolve and then drink the solution right away. Do not drink this product immediately before going to bed.

How much of this product should I take every day?

The amount of Fybogel Lemon liquid you should take will differ depending on your age:

  • Adults and children over 12 - Take 2 sachets a day, one in the morning and one in the evening, preferably after meals

  • Children aged 6 - 12 - Take half to 1 level teaspoonful (5ml spoonful) of Fybogel, once in the morning and once in the evening, preferably after meals

When should this product not be used?
