Som people can 'grow out' of penicillin allergies. Is this true?

In brief: Yes

There are follow up studies in children with penicillin allergy that showed a good chance (>85%) of losing skin reactivity to penicillin after 5 years of absolute avoidance.
Whether the allergy might come back with repeated exposure is not clear. We recommend caution, since anaphylaxis can not be predicted.

Allergy skin testing for penicillin can help determine whether someone has lost penicillin sensitivity. See an allergist for evaluation.
