He should avoid all macrolide antibiotics(erythromycin, clarithromycin,
spyramycin).
Azithromycin is an erythromicin derivate and others macrolide antibiotics
are erythromicin derivates ,too. Crossreaction is posible. But, you must
be sure to cause of allergy. Because
it is possible that the allergy is to azithromycin or to any adjuvante
supstance in suspension or cough syrup or new food (todlers). Allergy to
azithromycin is long lasting ( long t1/2 of drug) versus allergy to other
supstance in suspension.
