Xopenex

Why should Xopenex not be prescribed?

If Xopenex gives you an allergic reaction, you will not be able to use it.

Special warnings about Xopenex

There is a slight chance of developing an immediate, serious allergic reaction to Xopenex, with symptoms such as hives, rash, mouth and throat swelling, and bronchospasm (constricted airways and difficulty breathing). If this happens, or you experience bronchospasm alone, stop using Xopenex and call your doctor immediately.

If your asthma symptoms get worse despite Xopenex, call your doctor. He may need to add an anti-inflammatory steroid drug such as prednisone or beclomethasone to your treatment regimen.

Use Xopenex with caution if you have a heart condition, an irregular heartbeat, or high blood pressure. Call your doctor immediately if you notice any change in heartbeat, pulse, or blood pressure. Caution is also advised if you suffer from seizures, an overactive thyroid gland, or diabetes.

Possible food and drug interactions when taking Xopenex

Xopenex should be used cautiously, if at all, with other bronchodilators.

If Xopenex 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 Xopenex with the following:

• Antidepressant drugs classified as MAO inhibitors or tricyclics
• Beta blockers (heart and blood pressure drugs)
• Digoxin
• Diuretics (water pills) that lower your potassium levels

Special information if you are pregnant or breastfeeding

The effects of Xopenex 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 Xopenex appears in breast milk, but it's considered wise to either give up breastfeeding or discontinue the drug.
