Beclometasone inhalers

About inhaled beclometasone

Beclometasone inhalers (sometimes called "puffers") are used for asthma and chronic obstructive pulmonary disease (COPD).

They are known as "preventer" inhalers and are often brown or beige. If you have asthma or COPD, they help stop you getting symptoms.

Beclometasone inhalers are available on prescription only. Some inhalers contain beclometasone mixed with other medicines that help your breathing.

Beclometasone (sometimes written as "beclomethasone") is a type of medicine known as a corticosteroid (or steroid).

How and when to use your inhaler

Different types of inhalers

The usual dose is 1 or 2 puffs, taken twice a day.

It's important to use your beclometasone inhaler regularly to manage your condition. Keep using it, even if you do not have any symptoms. After using your inhaler, always put the lid back on to keep it clean.

Always follow the instructions from your doctor, or your asthma or respiratory nurse. They may tell you to use your inhaler more often, up to 4 times a day, or to have more than 2 puffs at a time. This depends on how bad your breathing is and which inhaler you're using.

There are different types of beclometasone inhaler. It's very important to use your inhaler properly. This is so you get the right amount of beclometasone into your lungs and the most benefit from your medicine.

Watch a video

Asthma UK has some short videos showing you how to use your inhaler to help you manage your symptoms. You can search by type of inhaler and by brand (such as Clenil, Fostair or Qvar).

If you use a pressurised metered-dose inhaler for example, you can watch a pMDI video.

Check your inhaler technique

To get the most from your inhaler, it's important to have your technique checked regularly.

If you're not sure how to use your inhaler, or your technique has not been checked for a year, ask your doctor, nurse or a pharmacist to watch you use it.

Using your inhaler with a spacer

If you or your child find it difficult to use an inhaler, your doctor or nurse may give you a spacer to use with it. Spacers can reduce the risk of side effects affecting your mouth and throat. They are particularly useful for giving beclometasone to young children.

A spacer is a large plastic container with a mouthpiece and a hole for the inhaler. It makes it easier to get the right amount of beclometasone into your lungs.

Your doctor, nurse or a pharmacist can show you how to use a spacer with your inhaler.

Will my dose go up or down?

Your dose may go up or down depending on how bad your breathing is. You will be prescribed the lowest dose that controls your symptoms.

If you have agreed a personal action plan with your doctor or nurse, follow your action plan.

What if I forget to use it?

Use your inhaler as soon as you remember. If it’s almost time for your next dose, skip the missed one and take your next dose as usual.

Do not take a double dose to make up for a forgotten dose.

If you forget doses often, it may help to set an alarm to remind you. You could also ask your pharmacist for advice on other ways to help you remember to take your medicine.

Do not stop using beclometasone suddenly, even if you feel better, without speaking to your doctor or nurse first.

What if I take too much?

Taking too much beclometasone by accident is unlikely to harm you.

If you're worried, talk to your doctor or a pharmacist.

Steroid cards

If you are using a steroid inhaler regularly, ask your doctor, nurse or a pharmacist if you need to carry a blue steroid card.


If you need any medical or dental treatment, show your blue steroid card to the doctor, dentist or pharmacist so they know that you're taking beclometasone.

Side effects

Common side effects

Like all medicines, beclometasone can cause side effects although not everyone gets them.

With inhaled beclometasone very little medicine gets into the rest of your body, so it's unlikely to give you side effects.

If you’re on high doses of beclometasone, or you’re also taking other steroid medicines or tablets for fungal infections or HIV, you may get underactive adrenal glands as a side effect. Ask your doctor if you need to carry a steroid emergency card.

These common side effects may happen in more than 1 in 100 people.

Keep taking the medicine but talk to your doctor if these side effects bother you or do not go away:

Serious side effects

It's unusual to have any serious side effects when using a beclometasone inhaler.

Side effects are more likely if you're on a higher dose of beclometasone for a long time (more than a few months).

Tell a doctor straight away if you get:

Serious allergic reaction

It happens rarely but it is possible to have a serious allergic reaction (anaphylaxis) to beclometasone.

This is different to an asthma attack. If you or your child have asthma symptoms, such as wheezing or have tightness in the chest or throat, use a reliever inhaler. If the symptoms do not improve or get worse, call 999 or go to A&E.

Call 999 or go to A&E if:

  • you get a skin rash that may include itchy, red, swollen, blistered or peeling skin
  • you have trouble breathing or talking
  • your mouth, face, lips, tongue or throat start swelling

You could be having a serious allergic reaction and may need immediate treatment in hospital.

Children and teenagers

Taking beclometasone at higher doses for a long time can slow down the normal growth of children and teenagers.

Your child's doctor will monitor their height and weight carefully for as long as they're taking this medicine. This will help them spot any slowing down of your child's growth and change their treatment if needed.

Even if your child's growth slows down, it does not seem to have much effect on their overall adult height.

Talk to your doctor if you're worried. They will be able to explain the benefits and risks of giving your child beclometasone.

You can report any suspected side effect to the UK safety scheme.

These are not all the side effects of beclometasone. For a full list see the leaflet inside your medicines packet.

How to cope with side effects

What to do about:

Pregnancy and breastfeeding

Beclometasone and pregnancy

Beclometasone inhalers are safe to use during pregnancy. Since it is taken into the lungs, very little of the medicine gets into your bloodstream and almost none gets to your baby. Even if a small amount does get to your baby, it will not harm them.

It's important to keep using beclometasone in pregnancy to ensure that your asthma or COPD is well controlled. Having a lung condition and breathing difficulties is dangerous for you and your baby.

You may find that you need extra beclometasone during pregnancy. This is fine and it's safe to increase the dose if you need to.

If your asthma or COPD gets worse during pregnancy then contact your doctor, midwife or specialist.

For more information about how using a beclometasone inhaler might affect you and your baby during pregnancy, read this leaflet on inhaled corticosteroids on the Best Use of Medicines in Pregnancy (BUMPS) website.

Beclometasone and breastfeeding

It's OK to use your beclometasone inhaler as normal while you're breastfeeding.

When beclometasone is used as an inhaler, tiny amounts are likely to be in breast milk. It is very unlikely to cause any side effects in your baby.

If you notice that your baby is not feeding as well as usual, or if you have any other concerns about your baby, talk to your health visitor, midwife or doctor as soon as possible.

Tell your doctor if you're:

  • trying to get pregnant
  • pregnant
  • breastfeeding

There's very little information about taking herbal remedies and supplements while taking or using beclometasone. Ask a pharmacist for advice.


Tell your doctor or pharmacist if you're taking any other medicines, including herbal remedies, vitamins or supplements.
