About bambuterol tablets
Type of medicine | A longer-acting beta2-agonist bronchodilator |
Used for | Asthma and other airways-related problems |
Also called | Bambec® |
Available as | Tablets |
Bambuterol is called a bronchodilator because it widens (dilates) your airways. It works by opening up the air passages in your lungs so that air can flow into your lungs more freely. For people with asthma this helps to relieve symptoms such as coughing, wheezing and feeling breathless, particularly at night.
There are other bronchodilator medicines which are available as inhalers and these tend to be preferred to tablets. You may, however, have been prescribed tablets if your symptoms are not fully eased by an inhaler alone, or if you have difficulty using an inhaler.
Beta2-agonists like bambuterol work by stimulating receptors called beta2 receptors in the muscles that line your airways. This relaxes these muscles, making your air passages widen, and this makes it easier for you to breathe.
Before taking bambuterol
Back to contentsSome 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 taking bambuterol it is important that your doctor knows:
If you have an overactive thyroid gland.
If you have heart or blood vessel problems, or an irregular heartbeat.
If you have high blood pressure.
If you have high sugar levels in your blood (diabetes).
If you have been told by a doctor that there are low levels of potassium in your blood.
If you are pregnant, trying for a baby or breastfeeding. This is because it is particularly important that your breathing is well controlled if you are pregnant.
If you have any problems with the way your liver works, or any problems with the way your kidneys work.
If you are taking or using any other medicines or inhalers. This includes any medicines you are taking 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.

How to take bambuterol
Back to contentsBefore you start the treatment, read the manufacturer's printed information leaflet from inside the pack. It will give you more information about bambuterol, and it will provide you with a full list of the side-effects which you could experience from taking it.
Take one tablet just before bedtime, with a drink of water. Take the tablet exactly as your doctor tells you to. Bambuterol can be taken with or without food.
If you forget to take a dose, take it as soon as you remember. If it is almost time to take your next dose, wait until then and take the dose that is due. Do not take two doses together to make up for a forgotten dose.
Getting the most from your treatment
Back to contentsTry to keep your regular appointments with your doctor. This is so your doctor can review your condition on a regular basis.
If you find that your symptoms are becoming worse or that you need to use a reliever (rescue) inhaler more regularly, contact your doctor or nurse for advice straightaway. If you have asthma, you will receive a written asthma action plan from your nurse or doctor which will help you to manage your asthma and tell you what to do if you have an asthma attack.
Do not smoke. Smoking causes irritation and damage to your lungs and will make your condition worse. Speak with your doctor or practice nurse for advice if you are having difficulty in stopping smoking.
If you have diabetes you may need to check your blood sugar (glucose) more frequently, as bambuterol can affect the levels of sugar in your blood. Your doctor will advise you about this.

Frequently asked questions
Why have I been prescribed bambuterol tablets instead of an inhaler?
Bambuterol tablets are often prescribed if your breathing symptoms are not fully controlled by an inhaler alone, or if you have difficulty using an inhaler device properly. Inhalers are generally preferred, but tablets offer an alternative in these situations.
How exactly does bambuterol help with my breathing?
Bambuterol is a bronchodilator. It works by stimulating specific receptors in the muscles lining your airways, causing these muscles to relax. This widening of the air passages allows air to flow more freely into your lungs, which helps relieve symptoms like coughing, wheezing, and breathlessness, especially at night.
I have diabetes. What do I need to know about taking bambuterol?
If you have diabetes, bambuterol can affect your blood sugar levels. Your doctor may advise you to check your blood sugar (glucose) more frequently while you are taking this medication. Always follow your doctor's guidance on managing your diabetes with bambuterol.
What should I do if my asthma symptoms get worse while taking bambuterol?
If you notice that your symptoms are worsening, or if you find yourself needing to use your reliever (rescue) inhaler more often, you should contact your doctor or nurse for advice straight away. If you have asthma, your healthcare provider will have given you a written action plan that outlines what to do during an asthma attack.
Can I take other medicines or herbal remedies with bambuterol?
Before starting bambuterol, it is very important to tell your doctor about all other medicines and inhalers you are currently taking. This includes any medicines you've bought without a prescription, as well as herbal or complementary remedies. Your doctor needs to know this to ensure that bambuterol is safe for you and won't interact negatively with anything else you're taking.
What are some common side-effects of bambuterol and what should I do about them?
Common side-effects include headache, feeling restless or shaky, disturbed sleep, muscle cramps, and being aware of your heartbeat. For headaches, you can try drinking plenty of water and taking a suitable painkiller. If the headaches continue, or if any other side-effects become troublesome or concerning, you should discuss them with your doctor or pharmacist for advice.
Is it important to keep my doctor's appointments while on bambuterol?
Yes, it is important to attend your regular appointments with your doctor. These appointments allow your doctor to monitor your condition, assess how well the bambuterol is working for you, and make any necessary adjustments to your treatment plan.
I'm pregnant or planning a pregnancy. Can I still take bambuterol?
If you are pregnant, trying for a baby, or breastfeeding, it's crucial to inform your doctor. It is particularly important that your breathing is well controlled during pregnancy, and your doctor will consider this as part of your treatment plan.
