Albuterol is used to prevent and treat wheezing, difficulty breathing, chest tightness, and coughing caused by lung diseases such as asthma and chronic obstructive pulmonary disease (COPD; a group of diseases that affect the lungs and airways). Albuterol is in a class of medications called bronchodilators. It works by relaxing and opening the air passages to the lungs to make breathing easier.

Albuterol comes as a tablet, a syrup, and an extended-release (long-acting) tablet to take by mouth. The tablets and syrup are usually taken three or four times a day. The extended-release tablets are usually taken once every 12 hours. Take albuterol at around the same times every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take albuterol exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.

Swallow the extended-release tablets whole with plenty of water or other liquid. Do not split, chew, or crush them.

Your doctor may start you on a low dose of albuterol and gradually increase your dose.

Albuterol may help control your symptoms but will not cure your condition. Continue to take albuterol even if you feel well. Do not stop taking albuterol without talking to your doctor.

Call your doctor if your symptoms worsen or if you feel that albuterol no longer controls your symptoms.

This medication may be prescribed for other uses; ask your doctor or pharmacist for more information.

Before taking albuterol,

• Tell your doctor and pharmacist if you are allergic to albuterol, any other medications, or any of the ingredients in albuterol tablets, extended-release tablets, or capsules. Ask your pharmacist for a list of the ingredients.
• Tell your doctor and pharmacist what prescription and nonprescription medications, vitamins, nutritional supplements, and herbal products you are taking or plan to take. Be sure to mention any of the following: beta blockers such as atenolol (Tenormin), labetalol (Normodyne), metoprolol (Lopressor, Toprol XL), nadolol (Corgard), and propranolol (Inderal); digoxin (Lanoxin); diuretics (‘water pills’); epinephrine (Epipen, Primatene Mist); other oral and inhaled medications for asthma and medications for colds. Also tell your doctor or pharmacist if you are taking the following medications or have stopped taking them within the past two weeks: antidepressants such as amitriptyline (Elavil), amoxapine (Asendin), clomipramine (Anafranil), desipramine (Norpramin), doxepin (Adapin, Sinequan), imipramine (Tofranil), nortriptyline (Aventyl, Pamelor), protriptyline (Vivactil), and trimipramine (Surmontil); and monoamine oxidase (MAO) inhibitors, including isocarboxazid (Marplan), phenelzine (Nardil), selegiline (Eldepryl, Emsam, Zelapar), and tranylcypromine (Parnate). Your doctor may need to change the doses of your medications or monitor you carefully for side effects.
• Tell your doctor if you have or have ever had an irregular heartbeat, heart disease, high blood pressure, hyperthyroidism (condition in which there is too much thyroid hormone in the body), diabetes, or seizures.
• Tell your doctor if you are pregnant, plan to become pregnant, or are breast-feeding. If you become pregnant while taking albuterol, call your doctor.
• You should know that albuterol sometimes causes wheezing and difficulty breathing. If this happens, call your doctor right away. Do not use albuterol again unless your doctor tells you that you should.

Unless your doctor tells you otherwise, continue your normal diet.

Take the missed dose as soon as you remember it. However, if it is almost time for the next dose, skip the missed dose and continue your regular dosing schedule. Do not take a double dose to make up for a missed one.

Keep this medication in the container it came in, tightly closed, and out of reach of children. Store it at room temperature and away from excess heat and moisture (not in the bathroom).

Unneeded medications should be disposed of in special ways to ensure that pets, children, and other people cannot consume them. However, you should not flush this medication down the toilet. Instead, the best way to dispose of your medication is through a medicine take-back program. Talk to your pharmacist or contact your local garbage/recycling department to learn about take-back programs in your community. See the FDA’s Safe Disposal of Medicines website (http://goo.gl/c4Rm4p) for more information if you do not have access to a take-back program.

It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location – one that is up and away and out of their sight and reach. http://www.upandaway.org
