Serevent contains the same active ingredient (salmeterol) as Soltel, and comes in two different formats. It relaxes your airways in the same way, but both strengths are limited to one dose only. Like Soltel, you’d need to combine Serevent with a corticosteroid inhaler. Unlike Soltel, it contains chlorofluorocarbons.
Inhalers such as Symbicort and Relvar Ellipta are combination inhalers, so contain both steroids and LABAs.
Salamol is a reliever which, like Soltel, is CFC-free.
