For children with acute asthma exacerbations, does levalbuterol work better or have fewer side effects than albuterol? What does this article say? Should we believe this study? Although mainly consistent with basic findings, clinical studies suggest no overwhelming superiority of levalbuterol over racemic albuterol; however, levalbuterol's effects may be greatest in moderate to severe asthma patients, especially with racemic albuterol overuse.
Recent adoption of the hydrofluoroalkane formulation has narrowed the cost gap between levalbuterol and racemic albuterol metered-dose inhalers, but it remains for the nebulized formulations. Thus, physician selection of these drugs has remained dependent on experience, pharmaceutical knowledge, and established prescribing habits combined with cost factors, formulary structures, and availability, such that racemic albuterol is still used significantly compared with levalbuterol to treat acute asthma exacerbations.
Never exceed the maximum recommended daily dosage. If Xopenex fails to provide relief at this dose, other medications will likely be needed to sustain long-term control of your asthma or COPD symptoms. Because of its convenience and simpler dosing schedule, Xopenex HFA is often the preferred choice for first-time users. On the other, nebulizers are easier to use with younger children and allow for accurate dosing for people with severe COPD or asthma.
Speak with your healthcare provider about the benefits and drawbacks of each. Both can be stored at room temperature, ideally between 68 degrees F and 77 degrees F. Do not store in direct sunlight or use after the expiration date. Keep out of reach of children. Using Nebulized Xopenex Solution. Never mix another inhaled medication with Xopenex nebulized solution unless your healthcare provider tells you to.
Xopenex is considered safe for long-term use with few intolerable side effects. The risk of side effects is dose-dependent, meaning that it increases in tandem with the dose or the frequency of dosing. Most of these side effects are mild and tend to resolve without treatment within an hour or so. Many will resolve fully as your body adapts to the medication. There are few severe side effects associated with Xopenex.
Of these, some are potentially life-threatening and require immediate medical attention. One such condition is known as paradoxical bronchospasm in which an inhaled beta-agonist causes an unexpected worsening of symptoms. While the cause is poorly understood, paradoxical bronchospasm often occurs with the first use of a new canister or vial. It can be life-threatening. It is also important to watch for signs of allergy.
While rare, some people have been known to develop rash or hives after using Xopenex. The drug may also cause anaphylaxis which, if left untreated, can lead to shock and death. Likewise, seek emergency medical attention if allergy symptoms develop rapidly and are accompanied by shortness of breath, wheezing, irregular heartbeats, dizziness, and the swelling of the face or throat.
Xopenex can affect potassium levels and, in some cases, lead to hypokalemia—a condition in which low potassium causes weakness, fatigue, muscle cramps and stiffness, and tingling or numbness. It is important to let your healthcare provider know if you experience these symptoms as hypokalemia can increase the risk of cardiovascular side effects.
Do not take a potassium supplement in an effort to avoid hypokalemia unless your healthcare provider tells you to. Doing so can interfere with other medications you may be taking, including ACE inhibitors. Xopenex is known to interact with certain drugs, either by increasing or decreasing drug concentrations of one or both drugs, or triggering severe side effects.
In some cases, a dose adjustment or separation of doses by one to four hours may be enough to compensate for the interaction. In others, a change of treatment may be indicated. Others still may require no adjustment at all. To avoid drug interactions, let your healthcare provider know about any and all drugs and supplements you take before starting Xopenex. This includes pharmaceutical, over-the-counter, nutritional, herbal, and recreational drugs.
