Why is Proventil prescribed?
Drugs containing albuterol are prescribed for the prevention and relief of bronchial spasms that narrow the airway. This especially applies to the treatment of asthma. Some brands of Proventil are also used for the prevention of bronchial spasm due to exercise.
Most important fact about Proventil
Do not take albuterol more frequently than your doctor recommends. Increasing the number of doses can be dangerous and may actually make symptoms of asthma worse.
If the dose your doctor recommends does not provide relief of your symptoms, or if your symptoms become worse, consult your doctor immediately.
How should you take Proventil?
If you are taking extended-release tablets, swallow them whole with some liquid--never chew or crush them.
Shake the inhalation aerosol canister well before using and make sure it's firmly seated in the plastic mouthpiece. Before using it for the first time, prime the canister with 4 sprays into the air away from your face. Prime it with 2 sprays whenever it has not been used for at least 4 days. Use only the adapter that comes with the product; do not use this adapter with any other product. Wash the plastic mouthpiece with warm running water at least once a week to prevent medication buildup and blockage.
If you are using an inhalation solution, be sure to protect it from contamination. Keep the tip of the dropper away from the lip of the bottle or any other surface. Do not use the solution if it changes color or becomes cloudy.
--If you miss a dose...
Take the forgotten dose as soon as you remember; then take any remaining doses for that day at equally spaced intervals. Never take a double dose.
--Storage instructions...

Why should Proventil not be prescribed?

Special warnings about Proventil
When taking albuterol inhalation aerosol, you should not use other inhaled medications before checking with your doctor.
Make sure the doctor is aware of it if you have a heart condition, seizure disorder, high blood pressure, abnormal heartbeat, overactive thyroid gland, or diabetes. Call your doctor immediately if you notice any change in heartbeat or pulse while taking Proventil.
You may have an immediate, serious allergic reaction to the first dose of albuterol, causing symptoms such as hives, rash, and swelling of the mouth, throat, lips, and tongue. The drug has been known to cause life-threatening bronchial spasms, especially with the first dose from a new canister or vial. There have also been rare reports of skin reddening and peeling in children taking albuterol syrup.
Do not exceed your doctor's recommended dose of albuterol. If you need more than usual, check with your doctor. Your asthma may be getting unstable, and you may need another medication. Do not, however, change your medication without first consulting your doctor or pharmacist.
Possible food and drug interactions when taking Proventil
Use albuterol inhalation aerosol with other aerosol bronchodilators only if your doctor recommends it.
If albuterol is taken with certain other drugs, the effects of either could be increased, decreased, or altered. It is especially important to check with your doctor before combining albuterol with the following:

Antidepressants classified as MAO inhibitors, such as Nardil and Parnate, and tricyclic antidepressants such as Elavil, Norpramin, Pamelor, and Tofranil.
Beta blockers (heart and blood pressure drugs such as Inderal, Tenormin, and Sectral)
Digoxin (Lanoxin)
Drugs similar to albuterol, such as Alupent, Brethine, Isuprel, and epinephrine
Drugs that lower potassium levels (water pills such as Lasix or HydroDIURIL)
Special information if you are pregnant or breastfeeding
The effects of albuterol during pregnancy have not been adequately studied. If you are pregnant or plan to become pregnant, inform your doctor immediately. It is not known whether albuterol appears in breast milk. If Proventil is essential to your health, your doctor may advise you to stop nursing your baby until your treatment is finished.
