518 Users are discussing this topic

Budesonide belongs to a class of medicines known as corticosteroids (more commonly called steroids). It reduces inflammation.

You will have been prescribed it to settle flare-up symptoms in the lower parts of your bowel.

The leaflet that comes inside your pack will give you full instructions for using the preparation you have been given. Please read it carefully.
Type of medicineA corticosteroid, also commonly called a steroid
Used forUlcerative colitis
Also calledBudenofalk® Rectal Foam; Entocort® Enema
Available asRectal foam and enema

Ulcerative colitis (UC) is a condition where patches of inflammation develop in your large intestine. The most common symptoms when the disease flares up are diarrhoea mixed with blood, and tummy (abdominal) pain. In between these flare-ups you may have few or no symptoms. If the patches are confined to the lower parts of your bowel (the colon and rectum), it may be helpful during flare-ups for you to be treated with a rectal preparation. This means giving budesonide into your back passage as an enema which you retain for a short time, or administering it as a foam.

Budesonide helps to reduce inflammation. A course of treatment will last a few weeks only - it will be stopped once your flare-up has settled.

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

  • If you are pregnant or breast-feeding (even though budesonide could still be prescribed for you).
  • If you have any kind of infection, or if you have ever had tuberculosis (TB).
  • If you have had a heart attack, or if you have a heart condition.
  • If you have any problems with the way your liver works, or if you have any problems with the way your kidneys work.
  • If you have sugar diabetes, or if you have an eye condition called glaucoma. You should also tell your doctor if a close member of your family has either of these conditions.
  • If you currently have any of the following conditions: high blood pressure, 'thinning' of the bones (osteoporosis), diverticulitis, an underactive thyroid, epilepsy, cataracts, or a condition causing severe muscle weakness, called myasthenia gravis.
  • If you have ever had any of the following: a blood clot in a blood vessel, a stomach ulcer, or a mental health problem such as depression or psychosis.
  • If you are taking any other medicines. This includes any medicines which are available to buy without a prescription, as well as herbal and complementary medicines.
  • If you have ever had an allergic reaction to a medicine, or if you have ever developed muscle pain after taking a steroid medicine.
  • Before you start the treatment, read the manufacturer's printed information leaflet from inside the pack. It will give you more information about budesonide, and will also provide you with a full list of the side-effects which you could experience from using it. It will also give you a step-by-step guide on how to use it.
  • Your doctor will tell you how to use budesonide. If you have been given Budenofalk® Rectal Foam, use one metered application once daily (you can use it in the morning or the evening, whichever suits you best). If you have been given Entocort® Enema, use one enema at bedtime.
  • Continue to use budesonide each day until your doctor tells you to stop. A course of treatment with Budenofalk® Rectal Foam may last up to eight weeks, whereas a course of treatment with Entocort® Enema is likely to last four weeks.

How to use Budenofalk® Rectal Foam

  1. Attach an applicator to the spray can nozzle and then shake the can well for about 15 seconds.
  2. Before you use the foam for the first time, remove the plastic safety lock from under the pump dome, and twist the dome until the small notch on the underneath of it is in line with the nozzle.
  3. Turn the spray vertically upside down.
  4. Insert the applicator into your back passage as far as is comfortable.
  5. Push down the pump dome on the container once, and then release it very slowly.
  6. Wait for 10-15 seconds before withdrawing the applicator.
  7. Remove the applicator and dispose of it in a plastic bag.

How to use Entocort® Enema

  1. Unscrew the nozzle section including the protective cap from one of the plastic bottles containing liquid.
  2. Drop one of the tablets from the foil strip into the bottle.
  3. Put the nozzle with the protective cap back on to the bottle and shake the bottle for 15 seconds, or until the tablet has dissolved.
  4. Lie down, then take off the protective cap and gently insert the nozzle into your back passage as far as is comfortable.
  5. Squeeze the bottle to empty it of most of the liquid, then remove the nozzle from your back passage and dispose of the bottle into a plastic bag.
  6. Roll over on to your stomach and stay like this for five minutes to keep the liquid in place. After this, get comfortable and allow yourself to go to sleep. The enema is intended to be retained (kept in your bowel) for as long as possible.
  • Try to keep your regular appointments with your doctor and clinic. This is so your doctor can check on your progress.
  • Budesonide can suppress your immune system, so it is important if you become ill that you make an appointment to see your doctor straightaway. Also, if you come into contact with anyone who has measles, shingles or chickenpox (or anyone who suspects they might have one of these viruses), you should see your doctor as soon as possible.
  • Some vaccines may not be suitable for you while you are being treated with budesonide. If you need any immunisations, make sure you mention that you are using a steroid medicine.
  • It is recommended that you should not drink grapefruit juice while you are on budesonide. This is because a chemical in grapefruit juice increases the amount of budesonide in your bloodstream and could make side-effects more likely.
  • If you are having an operation or any medical treatment, tell the person carrying out the treatment that you are using budesonide.
  • If you buy any medicines, check with a pharmacist that they are safe to take with your prescribed medicines.

Along with their useful effects, most medicines can cause unwanted side-effects although not everyone experiences them. The table below contains some of the most common ones associated with budesonide when used rectally. You will find a full list in the manufacturer's information leaflet supplied with your medicine. The unwanted effects often improve as your body adjusts to the new medicine, but speak with your doctor or pharmacist if any of the following continue or become troublesome.

Common rectal budesonide side-effects (these affect less than 1 in 10 people)What can I do if I experience this?
Local irritationThis should soon ease. If it continues, speak with your doctor
Wind, stomach upset, feeling sickStick to simple or bland foods - avoid fatty or spicy foods

For more information about side-effects which can develop when budesonide is taken by mouth or used long-term, see the separate leaflet called Oral Steroids.

If you experience any other symptoms which you think may be due to budesonide, speak with your doctor or pharmacist for further advice.

  • Keep all medicines out of the reach and sight of children.
  • Store in a cool, dry place, away from direct heat and light.
  • Budenofalk® Rectal Foam should only be used for four weeks once it has been opened. You will need to obtain a fresh supply if you are still using it after this time.

Never use more than the prescribed dose. If you suspect that you or someone else might have taken an overdose of this medicine, go to the accident and emergency department of your local hospital at once. Take the container with you, even if it is empty.

This medicine is for you. Never give it to other people even if their condition appears to be the same as yours.

Do not keep out-of-date or unwanted medicines. Take them to your local pharmacy which will dispose of them for you.

If you have any questions about this medicine ask your pharmacist.
