They are limited to infections due to germs defined as sensitive:
- documented angina at beta-hemolytic streptococcus A, as an alternative to beta-lactam therapy, especially when it can not be used,
- superinfections of acute bronchitis,
- exacerbations of chronic bronchitis;
- community-acquired pneumopathies, in subjects:
. without a risk factor,

. in the absence of clinical evidence suggestive of pneumococcal etiology.
In case of suspicion of atypical pneumopathy, macrolides are indicated whatever the gravity and the ground.
Official recommendations concerning the appropriate use of antibacterials should be taken into account.
