Proventil

What is Proventil

Proventil works by relaxing muscles in the airways to improve breathing.

Proventil is used to treat bronchospasm (wheezing, shortness of breath) associated with reversible obstructive airway disease such as asthma.

Proventil may also be used for conditions other than those listed in this medication guide.

General medical information about Proventil

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.

What you should find out before taking Proventil

Before taking Proventil, tell your doctor if you have:
- heart disease or high blood pressure;
- epilepsy or another seizure disorder;
- diabetes;
- an overactive thyroid (hyperthyroidism);
- difficulty swallowing;
- liver disease; or
- kidney disease.

You may not be able to take Proventil or you may require a dosage adjustment or special monitoring during treatment if you have any of the conditions listed above.

Proventil is in the FDA pregnancy category C. This means that it is not known whether it will harm an unborn baby. Do not take Proventil without first talking to your doctor if you are pregnant or could become pregnant during treatment.

It is not known whether Proventil passes into breast milk. Do not take Proventil without first talking to your doctor if you are breast-feeding a baby.

How should take Proventil

Take Proventil exactly as directed by your doctor. If you do not understand these directions, ask your pharmacist, nurse, or doctor to explain them to you.

Take each dose with a full glass of water.

To ensure that you get a correct dose, measure the liquid forms of Proventil with a special dose-measuring spoon or cup, not with a regular table spoon. If you do not have a dose-measuring device, ask your pharmacist where you can get one.

Do not break, crush, or chew the Volmax or Proventil Repetabs tablets. These are specially formulated to release the medication slowly in the body. The Volmax tablets have an outer shell that is not absorbed by the body. Occasionally, this shell may be seen in the stool. This is not a problem as the medication has been absorbed by the body.

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.

Store the Volmax brand of Proventil tablets in the refrigerator between 36 and 46 degrees Fahrenheit (2 and 8 degrees Celsius).

Store all other forms of Proventil at room temperature away from moisture and heat.

If you miss a dose:

Take the missed dose as soon as you remember. However, if it is almost time for the next regularly scheduled dose, skip the missed dose and take the next one as directed. Do not take a double dose of this medication.

What happens if you overdose:

Seek emergency medical attention.

Symptoms of an Proventil overdose may include angina or chest pain, irregular heartbeats or a fluttering heart, seizures, tremor, weakness, headache, nausea, and vomiting.

Avoid while taking Proventil

Avoid situations that may worsen your respiratory condition such as exercising in cold, dry air; smoking; breathing in dust; and exposure to allergens such as pet fur.

Possible side effects of Proventil

Stop taking Proventil and seek emergency medical attention if you experience any of the following serious side effects:
- an allergic reaction (difficulty breathing; closing of your throat; swelling of your lips, tongue, or face; or hives); or
- chest pain or irregular heartbeats.

Other, less serious side effects may be more likely to occur. Continue to take Proventil and talk to your doctor if you experience
- headache;
- dizziness or lightheadedness;
- insomnia;
- tremor or nervousness;
- sweating;
- nausea, vomiting, or diarrhea; or
- dry mouth.

Side effects other than those listed here may also occur. Talk to your doctor about any side effect that seems unusual or that is especially bothersome.
