It is possible that a beta-lactam alone can treat your pulmonary exacerbation without the side effects that come with an aminoglycoside. But if you only get a beta-lactam, your exacerbation might not improve as much as if you got both a beta-lactam and an aminoglycoside.
Medical tests
There can be discomfort from some of the medical tests, such as the pulmonary function test and sputum collection. These discomforts are the same as when you do these tests at your regular CF clinic visits.
