Levalbuterol HFA Interactions Explained
The following sections explain in detail the potentially negative interactions that can occur when levalbuterol HFA is combined with any of the drugs listed above.
Taking levalbuterol HFA and a beta blocker together can decrease the effectiveness of both medications. Additionally, people with asthma should generally avoid beta blockers, as they may worsen their condition. While some beta blockers are less likely than others to interact with levalbuterol HFA, all beta blockers can potentially cause problems.
Taking levalbuterol HFA and certain diuretics together can increase your risk of low potassium levels (hypokalemia), especially when you use levalbuterol HFA more frequently than recommended. Talk to your healthcare provider before using these medications together.
Digoxin (Digitek, Lanoxin)
Levalbuterol HFA may decrease the level of digoxin in your blood, perhaps making it less effective. Your healthcare provider may need to monitor the level of digoxin in your blood and adjust your digoxin dosage as necessary, especially when you are starting or stopping levalbuterol HFA.
Monoamine Oxidase Inhibitors (MAOIs)
Levalbuterol HFA should be used with extreme caution in combination with MAOIs. Dangerously low blood pressure (hypotension) may occur as a result. Talk to your healthcare provider before combining levalbuterol HFA with an MAOI.
Levalbuterol HFA should be used with extreme caution in combination with tricyclic antidepressants. Dangerously low blood pressure (hypotension) or an irregular heart rhythm (arrhythmia) may occur as a result. Talk to your healthcare provider before combining levalbuterol HFA with a tricyclic antidepressant.
