Frequently asked questions
Why can't salmeterol be used alone for asthma?
On its own it can hide worsening airway inflammation and raise the risk of severe attacks. An inhaled steroid treats the inflammation.
How is salmeterol different from salbutamol?
Both relax airways, but salmeterol is slow-starting and long-lasting, while salbutamol works fast for sudden symptoms.
Is shaking of the hands normal?
Mild tremor is common at first and often settles. Tell your doctor if it persists.
