In clinical studies, levalbuterol started working within 10 to 17 minutes, and the effects lasted for five to six hours, on average. In some people, the effects lasted as long as eight hours.
When and How to Take Levalbuterol
General considerations for when and how to take levalbuterol include the following:
- Levalbuterol comes in a liquid form that is used in a nebulizer. You will need to purchase or rent a nebulizer in order to take the medication.
- Regular levalbuterol vials are used without being diluted, while levalbuterol concentrate vials will need to be diluted by adding 2.5 mL of sterile normal saline solution (sodium chloride 0.9 percent).
- Make sure that you know exactly how to measure the dose and how to use and clean the nebulizer.
- For the medication to work properly, it must be taken as prescribed. Levalbuterol will not work if you stop taking it.
Dosing Information for Levalbuterol
The dose of levalbuterol that your healthcare provider recommends will vary, depending on a number of factors, including:

As is always the case, do not adjust your levalbuterol dose unless your healthcare provider specifically instructs you to do so.
