Uses for albuterol
Albuterol is used to treat bronchospasm or wheezing in patients with reversible obstructive airway disease, such as asthma.
Albuterol belongs to the family of medicines known as adrenergic bronchodilators. Adrenergic bronchodilators are medicines that open up the bronchial tubes (air passages) in the lungs. They relieve cough, wheezing, shortness of breath, and troubled breathing by increasing the flow of air through the bronchial tubes.
Albuterol is available only with your doctor's prescription.
Before using albuterol
In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For albuterol, the following should be considered:
Tell your doctor if you have ever had any unusual or allergic reaction to albuterol or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.
Appropriate studies performed to date have not demonstrated pediatric-specific problems that would limit the usefulness of albuterol in children 2 years of age and older.
No information is available on the relationship of age to the effects of albuterol in geriatric patients. However, elderly patients are more likely to have age-related heart problems, which may require caution and an adjustment in the dose for patients receiving albuterol.
There are no adequate studies in women for determining infant risk when using this medication during breastfeeding. Weigh the potential benefits against the potential risks before taking this medication while breastfeeding.
Interactions with medicines
Although certain medicines should not be used together at all, in other cases two different medicines may be used together even if an interaction might occur. In these cases, your doctor may want to change the dose, or other precautions may be necessary. When you are taking albuterol, it is especially important that your healthcare professional know if you are taking any of the medicines listed below. The following interactions have been selected on the basis of their potential significance and are not necessarily all-inclusive.
Using albuterol with any of the following medicines is usually not recommended, but may be required in some cases. If both medicines are prescribed together, your doctor may change the dose or how often you use one or both of the medicines.

Using albuterol with any of the following medicines may cause an increased risk of certain side effects, but using both drugs may be the best treatment for you. If both medicines are prescribed together, your doctor may change the dose or how often you use one or both of the medicines.
Interactions with food/tobacco/alcohol
Certain medicines should not be used at or around the time of eating food or eating certain types of food since interactions may occur. Using alcohol or tobacco with certain medicines may also cause interactions to occur. Discuss with your healthcare professional the use of your medicine with food, alcohol, or tobacco.
Other medical problems
The presence of other medical problems may affect the use of albuterol. Make sure you tell your doctor if you have any other medical problems, especially:
- Diabetes or
- Heart or blood vessel disease or
- Heart rhythm problems (e.g., arrhythmia) or
- Hypertension (high blood pressure) or
- Hyperthyroidism (overactive thyroid) or
- Hypokalemia (low potassium in the blood) or
- Seizure disorders—Use with caution. May make these conditions worse.
Proper use of albuterol
Use albuterol only as directed by your doctor. Do not use more of it and do not use it more often than your doctor ordered. Also, do not stop taking albuterol or any asthma medicine without telling your doctor. To do so may increase the chance for breathing problems.
Swallow the extended-release tablet whole with water or liquids. Do not break, crush, or chew the tablet.
Measure the oral liquid with a marked measuring spoon, oral syringe, or medicine cup. The average household teaspoon may not hold the right amount of liquid.
The dose of albuterol will be different for different patients. Follow your doctor's orders or the directions on the label. The following information includes only the average doses of albuterol. If your dose is different, do not change it unless your doctor tells you to do so.
The amount of medicine that you take depends on the strength of the medicine. Also, the number of doses you take each day, the time allowed between doses, and the length of time you take the medicine depend on the medical problem for which you are using the medicine.

Precautions while using albuterol
It is very important that your doctor check your progress or your child's progress at regular visits. This will allow your doctor to see if the medicine is working properly and to check for any unwanted effects.
Albuterol may cause paradoxical bronchospasm, which means your breathing or wheezing will get worse. Paradoxical bronchospasm may be life-threatening. Check with your doctor right away if you or your child have coughing, difficulty breathing, shortness of breath, or wheezing after using albuterol.
You or your child may also be taking an antiinflammatory medicine, such as a steroid, together with albuterol. Do not stop taking the antiinflammatory medicine, even if your asthma seems better, unless you are told to do so by your doctor.
Albuterol may cause allergic reactions. Stop using the medicine and check with your doctor right away if you or your child develop a skin rash, hives, itching, swelling, or any type of allergic reaction after taking albuterol.

Check with your doctor right away if you or your child have more than one of the following symptoms: convulsions; decreased urine; dry mouth; increased thirst; irregular heartbeat; loss of appetite; mood changes; muscle pain or cramps; nausea or vomiting; numbness or tingling in the hands, feet, or lips; shortness of breath; or unusual tiredness or weakness.
