De un vistazo
Albuterol is a bronchodilator medicine that widens airways to relieve asthma and COPD symptoms.
It is a "rescue" inhaler that quickly relieves breathlessness but does not prevent it.
Always carry your inhaler and use it as directed on your asthma action plan.
If your symptoms worsen or the inhaler stops working, contact your doctor immediately.
Common side effects include shakiness, headache, nervousness, and muscle cramps.
About albuterol
Tipo de medicamento | Bronchodilator (a short-acting beta2 agonist) |
Usado para | Asthma and other airways-related problems |
También llamado | Accuneb®; ProAir®; Proventil HFA®; Ventolin HFA®; |
Disponible como | Inhalation aerosol; dry powder inhaler; nebulizer solution |
Albuterol (also known as salbutamol) is called a bronchodilator medicine 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. This helps to relieve symptoms of asma y enfermedad pulmonar obstructiva crónica (EPOC) such as coughing, wheezing and feeling breathless. It starts to work within a few minutes and the effect will last between 3-5 hours.
Albuterol inhalers are often referred to as 'rescue' or 'quick-relief' medicines. This is because they relieve symptoms of breathlessness quickly. Although they relieve breathlessness, they do not prevent the breathlessness from happening.
The colour and style of your inhaler device will depend on the brand your physician has prescribed; make sure you receive the same brand each time you collect your medicine. Ask your pharmacist if you are unsure.
Before taking albuterol
Some medicines are not suitable for people with certain conditions, and sometimes a medicine may only be used if extra care is taken. For these reasons, before you start taking albuterol it is important that your physician knows:
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.
Si tienes una glándula tiroides hiperactiva.
Si tienes problemas del corazón o de los vasos sanguíneos, o si tienes un ritmo cardíaco irregular.
Si tienes presión arterial alta (hipertensión).
If you have high sugar levels in your blood (diabetes).
Si alguna vez has tenido una reacción alérgica a un medicamento.
Si está tomando otros medicamentos. Esto incluye cualquier medicamento que esté tomando y que esté disponible para comprar sin receta, así como medicamentos herbales y complementarios.
How to use albuterol inhalers
Before using your inhaler, read the manufacturer's printed information leaflet from inside the pack. The leaflet will give you more information about albuterol, diagrams to remind you how to use and clean your inhaler device, and a full list of side-effects which you may experience from using it.
Follow your physician's instructions carefully and make sure you know how to use your inhaler properly. There are several types of inhaler device. Some of these devices create a spray which you inhale, others are activated when you breathe in. If you are not sure how to use the device you have been given, ask your physician or pharmacist to show you.
You will receive a written asthma action plan from your physician to tell you how many puffs (inhalations) to use for each dose, and the maximum number of inhalations you should use in 24 hours. If you do not get relief from your symptoms after using the albuterol inhaler, you must contact your physician for advice straightaway.
Your physician may give you a spacer device to use with the albuterol inhaler, particularly if you struggle to co-ordinate breathing in and pressing the inhaler device. Spacer devices are also useful for giving albuterol to young children. The device helps to make sure that the medicine travels right into the lungs. Your physician or pharmacist will be able to advise you on how to use the spacer device with the inhaler.
Obteniendo el máximo de tu tratamiento
Try to keep your regular appointments with your physician and asthma clinic. This is so your physician can review your condition on a regular basis.
Make sure that you keep your albuterol inhaler with you all the time in case you need to use it. It should provide you with several hours' relief. If at any time you feel it is not working, you should let your physician know straightaway.
If you are using other inhalers at the same time, use the albuterol inhaler first and then wait for a few minutes before using the other inhalers. Albuterol opens your air passages to allow the other inhalers to work more effectively.
If at any time your breathing gets worse, continue to use your inhalers but also contact your physician for advice straightaway. Also, if you find you are using the maximum number of albuterol puffs (inhalations) every day, or if you continue to have symptoms despite using the maximum amount, you must let your physician know about this too, as you may require additional treatment.
Do not smoke. Smoking causes irritation and damage to the lungs, and will make your condition worse. Speak with your physician or pharmacist for further advice if you are having difficulty in stopping smoking.
Some inhalers may need to be 'primed' before first use and cleaned occasionally to ensure they continue to work properly. Follow the printed instructions that come with your device.
If you are having an operation or dental treatment, tell the person carrying out the treatment that you are taking albuterol.
If you buy any medicines, check with your doctor or a pharmacist that they are suitable for you to take with albuterol.

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 albuterol. 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 physician or pharmacist if any of the following continue or become troublesome.
Common albuterol side-effects | ¿Qué puedo hacer si experimento esto? |
Sensación de temblor | This feeling should soon pass. If not it may be a sign your dose is too high; let your physician know |
Dolor de cabeza | If the headaches continue speak with your physician; it may be a sign your dose is too high |
Nervous tension, muscle cramps, being aware of your heartbeat | If any of these become troublesome, speak with your physician or clinic |

Preguntas frecuentes
What is albuterol and how does it help with breathing problems?
Albuterol, also known as salbutamol, is a bronchodilator medicine. It works by widening (dilating) the airways in your lungs, allowing air to flow more freely. This helps to relieve symptoms like coughing, wheezing, and breathlessness associated with conditions such as asthma and COPD. Its effects typically start within a few minutes and last for about 3-5 hours.
Why is albuterol called a 'rescue' inhaler?
It's called a 'rescue' or 'quick-relief' medicine because it provides rapid relief for symptoms of breathlessness. However, it's important to remember that while it eases current symptoms, it doesn't prevent them from happening in the first place.
Can I use albuterol if I am pregnant or breastfeeding?
If you are pregnant, trying to conceive, or breastfeeding, it's important to inform your physician. They will need to ensure your breathing is well controlled, as this is particularly important during pregnancy.
What should I do if my albuterol inhaler doesn't seem to be working?
If you don't get relief from your symptoms after using your albuterol inhaler, or if you feel it's not working as effectively, you should contact your physician for advice straightaway. Also, if your breathing gets worse despite using your inhalers, or if you find you are using the maximum number of puffs every day and still have symptoms, inform your physician, as you may need additional treatment.
Are there any health conditions that mean I should be cautious about using albuterol?
Yes, it's important to tell your physician if you have an overactive thyroid gland, heart or blood vessel problems (including an irregular heartbeat or high blood pressure), high blood sugar levels (diabetes), or if you've ever had an allergic reaction to any medicine. Your physician needs this information to ensure albuterol is safe for you to use.
How long will one use of the albuterol inhaler relieve my symptoms?
After using your albuterol inhaler, the effect will typically last between 3 to 5 hours, providing relief from your symptoms during this period.
