Information on Tablets A-Z
Generic name: Levalbuterol hydrochloride
Why is this drug prescribed: Xopenex is a "bronchodilator." It works by relaxing the muscles in the walls of the lungs' many tiny airways (bronchioles), allowing them to expand so you can get more air. It is prescribed for asthma.
Most important fact about this drug: If your prescribed dosage of Xopenex does not provide relief, or your symptoms become worse, consult your doctor immediately.
How should you take this medication: Do not use more Xopenex than prescribed. Increasing the number of doses can be dangerous and may actually make your asthma worse. Xopenex should be taken only with an inhalation device called a nebulizer. Do not add any other drugs to the nebulizer without first asking your doctor. --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... Store unopened vials of Xopenex inhalation solution in their protective foil pouch at room temperature, away from light and excessive heat. Once the foil pouch has been opened, the vials should be used within 1 to 2 weeks. Once a vial has been opened, the contents should be used immediately or discarded. The solution should be colorless. If not, throw the vial out.
What side effects may occur: Side effects cannot be anticipated. If any develop or change in intensity, inform your doctor as soon as possible. Only your doctor can determine if it is safe for you to continue taking Xopenex.

Special warnings about this medication: 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 this medication: Xopenex should be used cautiously, if at all, with other bronchodilators such as Proventil, Ventolin, or Primatene Mist. 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 (Marplan, Nardil, and Parnate) or tricyclics (Elavil and Tofranil) Beta blockers (heart and blood pressure drugs) such as Inderal, Lopressor, and Tenormin Digoxin (Lanoxin) Diuretics (water pills) that lower your potassium levels such as Lasix and HydroDIURIL
