Pirbuterol Interactions

What other drugs affect Pirbuterol?

Before using this medication, tell your doctor if you are taking any of the following medicines:

• a beta-blocker (used to treat high blood pressure and other heart conditions) such as atenolol (Tenormin), metoprolol (Lopressor), or propranolol (Inderal). These medicines may greatly decrease the effects of pirbuterol and lead to an asthma attack
• other commonly used beta-blockers, including acebutolol (Sectral), bisoprolol (Zebeta), carteolol (Cartrol), carvedilol (Coreg), labetalol (Normodyne, Trandate), nadolol (Corgard), and pindolol (Visken)
• a tricyclic antidepressant such as amitriptyline (Elavil), doxepin (Sinequan), or nortriptyline (Pamelor). Very high blood pressure and other effects harmful to the heart may occur if these medicines are taken with pirbuterol
• other commonly used tricyclic antidepressants, including amoxapine (Asendin), clomipramine (Anafranil), desipramine (Norpramin), imipramine (Tofranil), and protriptyline (Vivactil)
• a monoamine oxidase (MAO) inhibitor such as isocarboxazid (Marplan), phenelzine (Nardil), or tranylcypromine (Parnate). Very high blood pressure and other effects harmful to the heart may also occur if these medicines are taken with pirbuterol
• another inhaled bronchodilator such as albuterol (Ventolin, Proventil), bitolterol (Tornalate), isoetharine (Bronkometer, Bronkosol), isoproterenol (Isuprel, Medihaler-Iso), metaproterenol (Alupent, Metaprel), salmeterol (Servent), or terbutaline (Brethaire, Brethine, Bricanyl). Using other inhaled medicines to open up your lungs will increase the risk of damage to your heart when you are taking pirbuterol
• caffeine, diet pills, or decongestants. These may also increase heart-related side effects

Drugs other than those listed here may also interact with pirbuterol inhalation, or affect your condition. Talk to your doctor and pharmacist before taking any prescription or over-the-counter medicines.

Avoid situations that may trigger an asthma attack such as exercising in cold, dry air; smoking; breathing in dust; and exposure to allergens such as pet fur.

Pirbuterol Dosage

How should I take Pirbuterol?

Take pirbuterol inhalation exactly as directed by your doctor. If you do not understand these directions, ask your pharmacist, nurse or doctor to explain them to you.
Shake the inhaler several times and uncap the mouthpiece. Breathe out fully and place your lips around the mouthpiece. Take a deep, slow breath as you push down on the canister. Hold your breath for several seconds, then exhale slowly.
The Autohaler releases the correct amount of drug. The force of your inhalation will trigger the release. You do not have to press down on a canister. Follow the instructions that accompany your inhaler.
If you take more than one dose at a time, wait for at least 1 full minute, then repeat the procedure.
Rinse your mouth after each use of the inhaler.
If you also use a steroid inhaler, use your pirbuterol inhaler first to open up your airways, then use the steroid inhaler as directed.
It is very important that you use your pirbuterol inhaler properly, so that the medicine gets into your lungs. Your doctor may want you to use a spacer with your inhaler. Talk to your doctor about proper inhaler use.
Seek medical attention if you notice that you require more than your usual or more than the maximum amount of any asthma medication in a 24-hour period. An increased need for medication could be an early sign of a serious asthma attack.
Keep your inhaler clean and dry. Keep the mouthpiece capped to avoid getting dirt inside it. Clean your inhaler once a day by removing the canister and mouthpiece and immersing it in warm water or alcohol. Allow the parts to dry, then reassemble the inhaler.
Carry your inhaler with you at all times in case of emergencies. Get a refill before you run out of medicine and before going on vacation.
